The quality of 'elite' publications such as The New Yorker leaves a lot to be desired these days. Adam Gopnik's recent outburst on Newtown is one more example of a downward trend: it is so breathtakingly bad that I am tempted to snark: "I can't breathe!" Could Gopnik really be as willfully stupid as the author of this piece? Or perhaps he was drunk when he posted his screed one minute after midnight on January 1st.
Luckily, I needn't waste any time disembarrassing this leftist goofball of his fallacies and fatuosities since a professional job of it as been done by John Hinderaker and Charles Cooke.
Again I ask myself: why is the quality of conservative commentary so vastly superior to the stuff on the Left?
A tip of the hat and a Happy New Year! to Malcolm Pollack from whom I snagged the above hyperlinks. Malcolm is a very good writer as you can see from this paragraph:
The New Yorker‘s essayist Adam Gopnik — whom I have always considered to be quite lavishly talented, despite his dainty and epicene style — beclowned himself one minute into this New Year with a stupendously mawkish item on gun control. It is so bad, in fact — so completely barren of fact, rational argument, or indeed any serious intellectual effort whatsoever — that I was startled, and frankly saddened, to see it in print. It is the cognitive equivalent, if one can imagine such a thing hoisted into Mr. Gopnik’s rarefied belletrist milieu, of yelling “BOSTON SUCKS” at a Yankees-Red Sox game, at a time when Boston leads the division by eleven games.
It is quite unreasonable to suppose that the appeal to sweet reason is the best way forward in all of life's situations. The reasonable appreciate that the hard fist of unreason applied to the visage of evil intransigence is sometimes the most cogent of 'arguments.'
It is unreasonable to be reasonable in all things.
Firearms instructors sometimes say that every gun is loaded. That is plainly false as it stands, but a wise saying nonetheless if interpreted to mean: every gun is to be presumed loaded until proven unloaded. Presumptions are procedural rules. To presume every gun to be loaded is to adopt a procedural rule to treat every gun as if it is loaded regardless of how antecedently likely it is that it is loaded. Suppose the likelihood is near zero: I examined the gun carefully an hour ago and I found it to be unloaded. Nevertheless, the presumption that it is loaded remains in force. I continue to behave as if it is loaded. For example, I don't point the gun at anything unless I want to destroy it.
I conclude that to presume that p is not to assert that p is true, nor to assert that p is probably true, nor to assume that p is true, but to decide to act as if p is true. A presumption, then, is not a proposition, although it embeds one. A presumption is something like a decision. More precisely, a presumption is the accusative of an act of presuming, an accusative that is not itself a proposition, but embeds one.
A presumption is not like a belief in the following important respect. To presume that a gun is loaded or that a man is innocent is not to believe that it is or that he is. To believe that p is to believe that p is true. But to presume that p is not to presume that p is true; it is to act as if p is true without either accepting or rejecting p. To presume that Jones is innocent until proven guilty is not to believe that he is innocent until proven guilty; it is to suspend judgment as to guilt or innocence until sufficient evidence is presented by the prosecution to warrant a verdict one way or the other. When I presume that p, I take no stand as to the truth-value of p — I neither accept nor reject p — what I do is decide to act as if p is true.
Presumptions must be defeasible. (I suspect that an indefeasible presumption is no presumption at all.) The presumption of being loaded is defeated in a particular case by carefully examining the gun and showing that it is unloaded. So while a presumption is not a proposition, it embeds a proposition that can be shown to be false. Defeasible presumption and burden-of-proof are correlative notions. (They are like rights and duties in this respect but also in that both are normative notions.) In a court of law, for example, if the accused enjoys a presumption of innocence, as he does in the Anglosphere, then the accuser bears a burden of proof, a burden which, if properly discharged, defeats the presumption.
Appeal to Ignorance?
So if person A claims to person B that a certain gun is unloaded, the burden of proof is on A to show that it is unloaded; person B does not bear the burden of proving that it is loaded. It is not just that he bears a lesser burden'; he bears no burden. Indeed it seems that B would be within his epistemic rights were he to claim that his ignorance of whether or not the gun is loaded is good evidence of its being loaded. But this is an appeal to ignorance. It has not been shown that the gun is unloaded; ergo, the gun is loaded.
It has not been shown that ~p; therefore p gives us the form of the ad ignorantiam 'fallacy.' Construed as a deductive argument, it is clearly invalid. Construed as an inductive argument, it will be in many cases weak. For example, suppose the gun is straight from the manufacturer and right out of the box. Then the probability of its being loaded is very low, and the argument: This gun out of the box has not been shown to be unloaded; ergo, this gun is loaded is very weak.
Nevertheless, safety considerations dictate a defeasible presumption in favor of every gun's being loaded, whether out of the box or not, a presumption that places the onus probandi on the one who maintains the opposite. So one might conclude that the appeal to ignorance in this case is reasonable even though the argument is deductively invalid and inductively weak.
The situation is similar to that in a court of law. The defendant is presumed innocent until proven guilty, so the burden of proof rests on either the state in a criminal proceeding, or on the plaintiff in a civil trial. In a criminal case the probative bar is set very high: the accused has to be shown guilty beyond a reasonable doubt. Here too there seems to be a legitimate appeal to ignorance: if it has not been shown that the defendant is guilty beyond a reasonable doubt, the conclusion to be drawn is that he is not guilty.
We will have to examine this more carefully in a separate post.
Safety Considerations
There are 'safety' considerations in both the gun example and the law example. It is because we want to be on the safe side — and not get shot — that we presume every gun to be loaded. "Better that a hundred guns be unnecessarily examined than that one sentient being be accidentally shot."
And it is because we want to be on the safe side — and not sentence an innocent person — that we presume the accused to be innocent until proven guilty. "Better that a hundred guilty people go free than that one innocent person be wrongly convicted."
But now what about God? Don't safety considerations apply here as well? If God exists, then our ultimate happiness depends on getting into right relation with him. So why can't one make a legitimate appeal to ignorance here? Now of course from the fact that no one has proven that God does not exist, it does not follow that God exists. That is an invalid deductive argument. That would be a truly fallacious instance of ad ignorantiam. But it is also invalid to infer than a gun is loaded because it hasn't been proven to be unloaded, or that a man is innocent because he hasn't been proven to be guilty. It just doesn't follow in any of these cases. And yet we reasonably consider the gun loaded and we reasonably find the accused to be innocent. And so why can't we reasonably presume God to exist on the basis of the fact that he hasn't been shown not to exist? If the burden of proof rests on the one who claims that gun is unloaded, why doesn't the burden of proof rest on the one who claims that God is nonexistent? We don't want to get shot, but we also don't want to lose our ultimate beatitude — if ultimate beatitude there be.
You can't say that that the burden of proof rests on the theist because he is making a positive claim; for there are positive claims that need no proof. And you can't say that the burden of proof rests on the theist because he is making an existential claim; for there are existential claims that need no proof. If you claim that extraterrestrial intelligent beings exist, then the burden is on you. But if you claim that there are Saguaro cacti in Arizona, then the burden of proof is not on you but on the one who denies it. Nor can you say that the burden rests on the theist because he is controverting the widely-accepted; the consensus gentium is that God exists.
Earlier I argued that we shouldn't bring BOP considerations into the God discussion at all. But if we do, why doesn't the BOP rest on the atheist?
Pigliucci's Confusion
Massimo Pigliucci thinks that if one understands who bears the burden of proof in a trial, then one ought to see right away that the burden of proof rests on the theist. For, "the burden of proof is always on the party making a positive claim, not on the one making a negative one." This strikes me as confused. It is true that the party making a complaint or bringing a charge is making a positive claim, but this is not the reason why the BOP rests on the accuser. It rests on the accuser because of the presumption of innocence that the accused enjoys. The BOP rests on the accuser not because his claim is positive but because of the procedural rule enshrined in our system of law according to which one is presumed innocent until proven guilty.
It is not true that the BOP is always on the one who makes a positive claim. 'That hillside is studded with Saguaro cacti' said to my hiking companion needs no proof. I shoulder no probative burden when I make a commonplace observation such as that. Therefore, the following is an unsound argument:
Everyone who make a positive claim bears a BOP. The theist makes a positive claim. ergo The theist bears the BOP in his debate with the atheist.
I argued above that if BOP considerations are relevant to the God debate, then the BOP is on the atheist. To appreciate the argument I gave, you have to realize that the God question is not merely theoretical. It is a practical question. In that respect it is like the gun safety and court room cases. My interest in whether or not a particular firearm is loaded or unloaded is not merely theoretical, or I should say, not at all theoretical. It is a practical interest in maintaining the health and physical integrity of myself and the people around me. Similarly with the law. If you are accused of homicide you are in deep trouble and face the loss of your liberty or your life. Arguably, the God question is in the same boat.
So I invite you to accept one or the other of the following conclusions. The BOP is borne by the atheist. BOP considerations should be kept out of the theist-atheist debate altogether.
A: The law of noncontradiction (LNC) is a law of thought merely.
B: I dispute your claim. LNC is not a law of thought merely; it is also a law of extramental reality.
In this example, B disputes what A says by making a counter-claim, a counter-assertion. Both are asserting. It strikes me as foolish to ask who has the burden of proof (BOP). How decide such a question? I assume that in a dialectical situation like the above, if BOP considerations are relevant at all, then the BOP is on one side or the other, but not on both, and not on neither. But there is no non-arbitrary way to place the onus probandi on one side or the other. Therefore, BOP considerations are a useless detour. Why not go straight to the question and evaluate the arguments pro et contra?
Suppose you say that the BOP rests on the one who opposes the received or traditional view. Then the BOP would be on A. But if you say that the BOP rests on the one who makes the stronger claim, the more committal claim, then the BOP would be on B. I don't see how there could be a non-arbitrary assignment of BOP in a dialectical situation like this. Correlatively, I don't see how it could be non-arbitrarily claimed that there is a defeasible presumption (DP) in favor of A's assertion or of B's. So I suggest we drop the BOP talk!
Concerning your dialogue: In my opinion, both A and B bear a burden of proof here. For that reason, it is an unlucky start of a dispute – because it is in fact the start of two disputes at once, and a dialectical confusion is likely to arise. In order that the dialogue be fruitful, B should not have put forward a negation of A's claim as his own claim, but simply refuse to accept A's claim until proved (this is the meaning of the rule Necessitas probandi incumbit ei qui dicit non ei qui negat – "negare" here has the technical meaning of "to refuse to concede until proved", according to the rules of disputation). If A failed to produce a proof, his case would fail. If he produced one, his case would succeed unless and until B attacked that proof, thus prompting another argument to "restore" the former one. And so on, until one of the parties failed to do their duty. Only if A was the one who so failed, would it be in place for B to state his opposite meaning as a claim, if he wishes, with the burden of proof incumbent on him
There are three, not two possible dialectical states of a proposition: (i) proved (ii) disproved (iii) neither. The "burden of proof" just means that the default state is (iii).
Perhaps our difference boils down to this: you think that a dispute is about truth or falsity of a proposition, whereas I think that it is about validity or invalidity of rational support of a proposition. Whereas from the former point of view the dialectical situation comes out as symmetric, in the latter view it is inherently asymmetric.
Reply to Novak
Part of our difference here may be due to a different understanding of 'dispute.' I think Lukas may be using it is a technical way similarly as he uses negare in a technical way. And perhaps these technical meanings are the same. When I used 'dispute' in the little dialog above I was using it to mean 'disagree with.' Lukas seems to be using it to mean 'refuse to concede until argument is provided.'
Lukas seems just to be assuming that the BOP rests on A who must "produce a proof" otherwise his "case would fail." I take that to mean that A is obliged to give an argument for the claim he has made. (In my book, an argument is not the same as a proof, although every proof is an argument.) But, by my lights, if so, then the same goes for B: he too must give an argument for his counterclaim. B cannot just cross his arms across his chest and say, "I don't have to give an argument for my assertion; it suffices for me to poke holes in your argument. The BOP is on you, not on me." This is precisely what I reject. Otherwise, there would be a presumption in favor of B's claim. But there isn't. And to insist that there is, is to beg a philosophical question.
I think Lukas is right when he says that, for me, the dialectical situation is symmetric, at least in the example given above, while for him it is asymmetric.
Lukas is also right when he says that, for me, the dispute (disagreement) is about the truth-value of a proposition: Is it true or is it false that LNC is a law of thought merely? He says that, for him, the disagreement is "about validity or invalidity of rational support of a proposition."
But this needs explaining. Validity and invalidity are technical concepts from formal logic. Our present topic, however, is not formal logic, but dialectics. Lukas seems to think that there are certain procedural rules that govern the conduct of a discussion, and that these rules induce certain rights and duties in the interlocutors. Thus, he who makes an assertion puts himself under a dialectical obligation to support his assertion with one or more arguments, while the one to whom the assertion is made is under no obligation to support the negation of the asserted proposition: he has the right to do no more than find fault with the arguments for the asserted proposition.
I am skeptical of this entire adversarial model which has its provenience in the court-room situation and makes perfect sense there, but seems to me not appropriate in philosophy which, by my lights, is not a matter of debate or disputation but one of dialogue in which the interlocutors are not out to prove propositions they antecedently accept and do not question, but who aim at arriving at the truth together, a truth that they do not claim to possess, but are seeking.
. . . by my lights, parsimony might be a consideration that puts the burden of proof on the theist. Theories that multiply entities unnecessarily are less likely to be true and the theist's theory postulates an entity. Now, it may be that the theist will say that we need God as a first cause or something like that– that could be enough to absolve him of the burden. But in the absence of other reasons for believing in God (known to the interlocutors), the burden of proof would be on the theist.
Let's think about this. I doubt the usefulness in philosophy of burden-of-proof considerations, at least when we are discussing such big questions as God, freedom, and immortality. I also doubt the usefulness in philosophy of considerations of parsimony. What is parsimony anyway?
Parsimony
Parsimony or Occam's Razor is a principle of theoretical economy that states or rather enjoins:
OR. Do not multiply entities beyond necessity.
It is sometimes formulated in Latin: Entia non sunt multiplicanda praeter necessitatem. The principle or rather injunction is presumably to be interpreted qualitatively rather than quantitatively, thus:
OR*. Do not multiply TYPES or CATEGORIES of entity beyond necessity.
Thus it is not individual entities that are not to be multiplied, but types or kinds or categories of entity. To illustrate. Some criticized David Lewis' extreme modal realism on the ground that it proliferates concreta: there are not only all the actual concreta , there are all those merely possible ones as well. He responded quite plausibly to the proliferation charge by pointing out that the Razor applies to categories of entity, not individual entities, and that category-wise his ontology is sparse indeed.
'Multiply' is a picturesque way of saying posit. (Obviously, there are as many categories of entity as there are, and one cannot cause them to 'multiply.') And let's not forget the crucial qualification: beyond necessity. That means: beyond what is needed for purposes of adequate explanation of the data that are to be explained. Hence:
OR** Do not posit types of entity in excess of what is needed for purposes of explanation.
So the principle enjoins us to refrain from positing more types of entity than we need to explain the phenomena that need to be explained. It is obvious that (OR**) does not tell us to prefer theory T1 over theory T2 if T1 posits fewer types of entity than T2. What it tells us is to prefer T1 over T2 if T1 posits fewer types of entity AND accounts adequately for all the data. So there is a trade-off between positing and accounting.
Spencer tells us that "Theories that multiply entities unnecessarily are less likely to be true . . . ." I don't think this is right. Theories that posit entities or types of entity beyond the needs of explanation are uneconomical and to be rejected for this reason. We prefer simpler theories to save cognitive labor, not because simplicity is the mark of truth (simplex sigillum veri) or even because simpler theories are more likely to be true. Now it may be that simpler theories are more likely to be true — how would one show this? — but this is no part of the principle of parsimony as I understand it. It is a principle of Denkoekonomie.
The defeasible presumption in favor of parsimonious explanations is very much like the defeasible presumption of innocence (POI) in the law. The accused is presumed innocent until proven guilty even if the probability of his being innocent is low or even near or at zero. The presumption of innocence does not vary with the probability of innocence, and is in fact logically consistent wth guilt. And of course the presumption of innocence does not entail innocence.
POI is a procedural rule: we proceed in the law as if the accused is innocent even if it is evident that he isn't. (Suppose 100 reputable winesses observe a man in a non-self-defense situation bludgeoning a woman to death. There still has to be a trial, the accused will enjoy the POI, and the prosecutors will bear the burden of proof. It's just that this trial will be very short.) Similarly, the principle of parsimony is a principle of procedural presumption. (See N. Rescher, Presumption and the Practices of Tentative Cognition, Cambridge UP, 2006. p. 124 ff.)
God
Suppose everything could be explained just as well without God as with God. Then we would have no reason to posit God as playing an explanatory role. But it wouldn't follow that God doesn't exist, or even that it is unlikely that God exists. All that would follow is that we would have no reason to posit God as an explanation of the existence, order, intelligibility of the universe: The 'God hypothesis' would not be rationally motivated.
Now one point I want to make is that Parsimony is a fairly useless and trivial injunction. After all, who wants to posit types of entity in excess of what is needed for purposes of explanation? The real question is what is needed for explanation. Parsimony gives us no help with this question. I would argue that God is needed to explain the existence and the intelligibility of the universe. Now that is a meaty set of issues that cannot be resolved by brandishing the Razor. We all agree about the Razor. What we don't agree about is what is necessary for an adequate explanation of what needs explaining.
And so it would be a cheap shot for an atheist to claim that theists violate Parsimony by positing God. Spencer of course understands this. For again, the issue is whether the posit is necessary for explanation.
Burden of Proof
Who bears the burden? Theist or atheist? The question is senseless or else has a trivial answer: both bear it. For it is not evident that God exists, nor it is evident that God does not exist. Neither side can invoke a defeasible presumption.
But there is a defeasible presumption in favor of the reliability of memory as a source of knowledge; so it does make sense to place the burden of proof on one who denies it.
Finally, does parsimony put the burden of proof on the theist as Spencer claims? No and for two reasons. First, Parsimony is a trivial injunction that, by itself, cannot decide between theism and atheism. Second, it is either senseless or trivial to ask where the BOP lies in the atheism-theism dispute.
UPDATE (10/28): Spencer Case e-mails: "I think you should make clear to your readers that your post attributes views to me that I do not hold. The part you quote from me is given in a context that is meant to show how my view of burden of proof would apply to a particular dialectical situation where an atheist thought parsimony mattered for the reason I stated. I wasn't actually subscribing to that view of parsimony. My account of what philosophical burden of proof amounts to was the main point of my comments.
Andrew Bailey sends the following quotations for our delectation:
"(When a philosopher says, "The burden of the proof lies on you", he means, "You must deduce your conclusion from the truths of immediate sensory experience by means of an argument that is formally valid according to the rules of elementary logic; I on the other hand may employ any dialectical tactic I find expedient".)"
-PvI, An Essay on Free Will, p.18
"Where does the burden of proof lie in a philosophical debate? In a debate of the type we are imagining, the answer is clear–in fact, trivial. The burden of proof lies on the person who's trying to prove something to someone."
-PvI, The Problem of Evil, p.46
Notice that the thesis encoded in the second is a little different (and much more plausible) than "he who asserts must prove".
I'd have to examine the context, but the second quotation seems to support what I was saying yesterday, namely, that burden-of-proof considerations have no non-trivial role to play in philosophical discussions.
It is quite otherwise in the law, which is where we get the notion of burden of proof (BOP) and the correlative notion of defeasible presumption (DP). As N. Rescher remarks (Presumption and the Practices of Tentative Cognition, p. 13), both are at root legal conceptions dating back to Roman law. Now court-room proceedings are essentially both practical and adversarial: what is in dispute is not a matter of theory, but a matter bearing upon such things as a person's wealth and liberty. Thus it makes perfect sense that the BOP should be placed on the plaintiff in a civil case and the state in a criminal case, which is equivalent to granting to the accused a defeasible presumption of innocence. The onus probandi rests on those who make allegations. Thus it makes sense within the law to maintain that
Necessitas probandi incumbit ei qui dicit non ei qui negat.
The need for proof lies with him who affirms, not him who denies.
Now to my way of thinking, philosophy-as-inquiry is never adversarial, and is primarily theoretical. This is part of my reason for thinking that the fundamentally legal notions of BOP and DP ought not be imported into philosophy-as-inquiry. It strikes me as very clear that one who makes an accusation bears the burden of proof. But it is not so clear that one who makes an assertion bears a burden of proof.
Indeed, it is either false or meaningless. For if van Inwagen asserts that there are no modes of being, and I assert that there are, then we both make assertions. So if he who asserts bears a burden of proof, then we both bear the burden of proof — which trivializes the very notion of BOP.
So I am skeptical about the importation of the fundamentally legal concept of BOP from that essentially adversarial and practical dialectical context into philosophy-as-inquiry. But this is a complicated topic. I'll say some more tomorrow.
1. The question this post raises is whether it is at all useful to speak of burden of proof (BOP) in dialectical situations in which there are no agreed-upon rules of procedure that are constitutive of the 'game' played within the dialectical situation. By a dialectical situation I mean a context in which orderly discussion occurs among two or more competent and sincere interlocutors who share the goal of arriving as best they can at the truth about some matter, or the goal of resolving some question in dispute. My main concern is with dialectical situations that are broadly philosophical. I suspect that in philosophical debates the notion of burden of proof is out of place and not usefully deployed. That is what I will now try to argue.
2. I will begin with the observation that the presumption of innocence (POI) in an Anglo-American court of law is never up for grabs in that arena. Thus the POI is not itself presumptively maintained and subject to defeat. If Jones is accused of a crime, the presumption of his innocence can of course be defeated, but that the accused must be presumed innocent until proven guilty is itself never questioned and of course never defeated. The POI is not itself a defeasible presumption. And if Rescher is right that there are no indefeasible presumptions, then the POI is not even a presumption. The POI is a rule of the 'game,' and constitutive of the 'game.' The POI in a court room situation is like a law of chess. The laws of chess, as constitutive of chess, cannot themselves be contested within a game of chess. In a particular game a dispute may arise as to whether or not a three-fold repetition of position has occurred. But that a three-fold repetition of position results in a draw is not subject to dispute. The reason there is always a definite outcome in chess (win, lose, or draw) is precisely because of the non-negotiable chess-constitutive laws. These laws, of course, are not inscribed in the nature of things, but are conventional in nature.
As I pointed out earlier, defeasible presumption (DP) and burden of proof are correlative notions. The defeasible presumption that the accused is innocent until proven guilty places the onus probandi on the prosecution. Therefore, from the fact that the POI is not itself defeasible in a court of law, it follows that neither is the BOP. Where the initating BOP lies — the BOP that remains in force and never shifts during the proceedings — is never subject to debate. It lies on the state in a criminal case and on the plaintiff in a civil case. If you agree to play the game, then you agree to its constitutive rules. Since these rules are constitutive of the game, they cannot be rejected on pain of ceasing to play the particular game in question.
3. But in philosophy matters are otherwise. For in philosophy everything is up for grabs, including the nature of philosophical inquiry and the rules of procedure. (This is why metaphilosophy is not 'outside of' philosophy but a branch of same.) And so where the BOP lies in a debate between, say, atheists and theists is itself a matter of debate and bitter contention. Each party seeks to put the BOP on the other, to 'bop' him if you will. The theist is inclined to say that there is a defeasible presumption in favor of the truth of theism; but of course few atheists will meekly submit to that pronunciamento. If the theist is right in his presumption, then he doesn't have to do anything except turn aside the atheist's objections: he is under no obligation to argue positively for theism any more than the accused is under an obligation to prove his innocence.
Accused to accuser: "I don't have to prove my innocence; you have to prove my guilt. I enjoy the presumption of innocence; you bear the burden of proof."
Theist to atheist: "I don't have to prove that God exists; you have to prove that God does not exist. Theism enjoys the presumption of being true; atheism bears the burden of proving that theism is not true." (This assumes that BOP and DP are legitimately deployed within broadly philosophical precincts — which I am denying.)
Note that if the theist invokes the above presumption he needn't be committing the ad ignorantiam fallacy. He needn't be saying that theism is true because it hasn't been proved to be false. Surely the following deductive argument is invalid:
No one has ever proved that God does not exist ergo God does exist.
Just as the presumption of innocence does not entail that the accused is innocent, the presumption of truth does not entail that the proposition presumed true is true. So the mere fact that I have the presumption on my side does not amount to an argument that what I am presuming is true. If I have the presumption on my side, then my dialectical opponent bears the BOP. That's all.
4. Now we come to my tentative suggestion. There is no fact of the matter as to where the BOP lies in any dialectical context, legal, philosophical or any other: it is a matter of decision and agreement upon what has been conventionally decided. In chess, for example, the rules had to be decided and the players have to agree to accept them. No one thinks that these rules are inscribed in rerum natura. The same goes for BOP and DP. It had to be decided that in court room discourse and dialectic the accused enjoys the DP and the accuser(s) the BOP.
In philosophical discourse, however, there are no procedural rules regarding DP and BOP that we will all agree on.
For example, according to Douglas N. Walton, ". . . the basic rule of burden of proof in reasonable dialogue is: He who asserts must prove." (Informal Logic, p. 59) That is clearly false. If I assert that that you left the door open, there is no need for me to prove my assertion. A proof is an argument having premises and conclusion. Surely there is no need to argue for matters evident to sense perception. In fact, it would be unreasonable to do so. Or suppose I assert the Law of Noncontradiction. There is no way I can (non-circularly) prove it. So I cannot be under any epistemic obligation to prove it. 'Ought' implies 'can.'
And how would this work in a dispute between theist and atheist? I assert that God exists and you assert that God does not exist. We both assert. So we both bear the BOP, and we both enjoy DP? But then BOP and DP have no application in this area.
I have heard it said that the BOP lies on the one who makes a positive (affirmative) assertion. But surely both theist and atheist make positive assertions about reality. 'Reality is such that God exists.' 'Reality is such that God does not exist.' Both propositions are logically affirmative.
Suppose our atheist denies God by saying 'God is an unconscious anthropomorphic projection.' Logically, that is an affirmative proposition. Will you conclude that the BOP is on the atheist?
Some say that presumptions are essentially conservative: there is a presumption in favor of the existing and the established and against the novel, the far-out, and what runs contrary to prevailing opinion. "If it ain't broke, don't fix it." Suppose I give the following speech:
There is a presumption in favor of every existing institution, long-standing way of doing things, and well-entrenched and widespread way of belief. Now the consensus gentium is that God exists. And so I lay it down that there is a defeasible presumption in favor of theism and that the burden of proof lies squarely on the shoulders of the atheist. Theism is doxastically innocent until proven guilty. The theist need only rebut the atheist's objections; he needn't make a positive case for his side.
Not only would the atheist not accept this declaration, he would be justified in not accepting it, for reasons that are perhaps obvious. For my declaration is as much up for grabs as anything else in philosophy. And of course if I make an ad baculum move then I remove myself from philosophy's precincts altogether. In philosophy the appeal is to reason, never to the stick.
The situation in philosophy could be likened to the situation in a court of law in which the contending parties are the ones who decide on the rules of procedure, including BOP and DP rules. Such a trial could not be brought to a conclusion. That's the way it is in philosophy. Every procedural rule and methodological maxim is further fodder for philosophical Forschung. (Sorry, couldn't resist the alliteration.)
My tentative conclusion is as follows. In philosophy no good purpose is served by claims that the BOP lies on one side or the other of a dispute, or that there is a DP in favor of this thesis but not in favor of that one. For there is no fact of the matter as to where the BOP lies. BOP considerations are usefully deployed only in dialectical situations in which there is an antecedent conventional agreement on the rules of procedure, rules that constitute the dialectical 'game' in question, and that are agreed upon by the players of the game and never contested by them while playing it.

But we need to nuance this a bit inasmuch as (1) conflates the distinction between
1a. Philosophical inquiry pursued in order to support (defend and rationally justify) an antecedently held thesis or worldview whose source is extraphilosophical, a thesis or worldview that will continue to be maintained whether or not the defensive and justificatory operations are successful
and
1b. Philosophical inquiry pursued in order to support (defend and rationally justify) an antecedently held thesis or worldview whose source is extraphilosophical, a thesis or worldview that will continue to be maintained only if the defensive and justificatory operations are successful.
Alvin Plantinga may serve as an example of (1a). I think it is fair to say that his commitment to his Dutch Reformed Christian worldview is such that he would continue to adhere to it whether or not his technical philosophical work is judged successful in defending and rationally justifying it. For a classical example of (1a), we may turn to Thomas Aquinas. His commitment to the doctrine of the Incarnation does not depend on the success of his attempt at showing the doctrine to be rationally acceptable. (Don't confuse rational acceptability with rational provability. The Incarnation cannot of course be rationally demonstrated.) Had his amanuensis Reginald convinced him that his defensive strategy in terms of reduplicatives was a non-starter, Thomas would not have suspended his acceptance of the doctrine in question; he would have looked for a defense immune to objections.
There are of course atheists and materialists who also exemplify (1a). Suppose a typical materialist about the mind proffers a theory that attempts to account for qualia and intentionality in purely naturalistic terms, and I succeed in showing him that his theory is untenable. Will he then reject his materialism about the mind or suspend judgment with respect to it? Of course not. He will 'go back to the drawing board' and try to develop a naturalistic theory immune to my objections.
The same thing goes on in the sciences. There are climate scientists who are committed to the thesis that anthropogenic global warming is taking place. They then look for evidence to buttress this conviction.
According to Susan Haack, following C. S. Peirce, the four examples above (which are mine, not hers) are examples of pseudo-inquiry:
The distinguishing feature of genuine inquiry is that what the inquirer wants is to find the truth of some question. [. . .] The distinguishing feature of pseudo-inquiry is that what the 'inquirer' wants is not to discover the truth of some question but to make a case for some proposition determined in advance. (Manifesto of a Passionate Moderate, University of Chicago Press, 1998, p. 8)
Haack, again following Peirce, distinguishes within pseudo-inquiry sham inquiry and sham reasoning from fake inquiry and fake reasoning. You engage in sham reasoning when you make "a case for the truth of some proposition your commitment to which is already evidence- and argument-proof." (8) Characteristic of the sham 'inquirer' is a "prior and unbudgeable commitment to the proposition for which he tries to make a case." (9)
There are also those who are indifferent to the truth-value of the thesis they urge, but argue for it anyway to make a name for themselves and advance their careers. Their reasoning is not sham but fake. The sham reasoner is committed to the truth of the thesis he urges; the fake reasoner isn't: he is a bullshitter in Harry Frankfurt's sense. I will not be concerned with fake inquiry in this post.
The question I need to decide is, first of all, whether every case of (1a) is sham inquiry. And the answer to that is No. That consciousness exists, for example, is something I know to be true, and indeed from an extraphilosophical source, namely, introspection or inner sense. Those who claim that consciousness is an illusion are frightfully mistaken. I would be within my epistemic rights in simply dismissing their absurd claim as a bit of sophistry. But suppose I give an argument why consciousness cannot be an illusion. Such an argument would not count as sham reasoning despite my mind's being made up before I start my arguing, despite my "prior and unbudgeable commitment to the proposition" for which I argue.
Nothing is more evident that that consciousness, in my own case at least, exists. Consider a somewhat different case, that of other minds, other consciousnesses. Other minds are not given in the way my own mind is given (to me). Yet when I converse with a fellow human being, and succeed in communicating with him more or less satisfactorily, I am unshakably convinced that I am in the presence of an other mind: I KNOW that my interlocutor is an other mind. And in the case of my cats, despite the fact that our communication does not rise to a very high level, I am unbudgingly convinced that they too are subjects of consciousness, other minds. As a philosopher I want to know how it is that I have knowledge of other minds; I seek a justification of my belief in them. Whether I come up with a decent justification or not, I hold fast to my belief. I want to know how knowledge of other minds is possible, but I would never take my inability to demonstrate possibility as entailing that the knowledge in question is not actual. The reasoning I engage in is genuine, not sham, despite the fact that there is no way I am going to abandon my conviction.
Suppose an eliminative materialist claims that there are no beliefs or desires. I might simply dismiss his foolish assertion or I might argue against it. If I do the latter, my reasoning is surely not sham despite my prior and unbudgeable commitment to my thesis.
Suppose David Lewis comes along and asserts that unrealized possibilities are physical objects. I know that that is false. Suppose a student doesn't see right off the bat that the claim is false and demands an argument. I supply one. Is my reasoning sham because there is no chance that I will change my view? I don't think so.
Suppose someone denies the law of noncontradiction . . . .
There is no need to multiply examples: not every case of (1a) is sham inquiry. Those who claim that consciousness is an illusion or that there are no beliefs and desires can, and perhaps ought to be, simply dismissed as sophists or bullshitters. "Never argue with a sophist!" is a good maxim. But deniers of God, the soul, the divinity of Christ, and the like cannot be simply dismissed as sophists or bullshitters.
So now we come to the hard cases, the interesting cases.
Consider the unshakable belief held by some that there is what William James calls an "unseen order." (Varieties of Religious Exerience, p. 53) Some of those who have this belief claim to have glimpsed the unseen order via mystical experience. They claim that it lies beyond the senses, outer and inner, and that is also lies beyond what discursive reason can grasp. And yet they reason about it, not to prove its existence, but to show how it, though suprarational, is yet rationally acceptable. Is their reasoning sham because they will hold to their conviction whether or not they succeed in showing that the conviction is rationally acceptable?
I don't think so. Seeing is believing, and mystical experience is a kind of seeing. Why trust abstract reasoning over direct experience? If you found a way out of Plato's Cave, then you know there is a way out, and all the abstract reasoning of all the benighted troglodytes counts for nothing at all in the teeth of that experience of liberation. But rather than pursue a discussion of mystical experience, let's think about (propositional) revelation.
Consider Aquinas again. There are things he thinks he can rationally demonstrate such as the existence of God. And there are things such as the Incarnation he thinks cannot be rationally demonstrated, but can be known to be true on the basis of revelation as mediated by the church's teaching authority. But while not provable (rationally demonstrable), the Incarnation is rationally acceptable. Or so Thomas argues. Is either sort of reasoning sham given that Aquinas would not abandon belief in God or in the Incarnation even if his reasoning in either case was shown to be faulty? Russell would say yes:
There is little of the true philosophic spirit in Aquinas. He does not, like the Platonic Socrates, set out to follow wherever the argument may lead. He is not engaged in an inquiry, the result of which it is impossible to know in advance. Before he begins to philosophize, he already knows the truth; it is declared in the catholic faith. If he can find apparently rational arguments for some parts of the faith, so much the better; if he cannot, he need only fall back on revelation. The finding of arguments for a conclusion given in advance is not philosophy, but special pleading. (Bertrand Russell, The History of Western Philosophy, Simon and Schuster, p. 463)
.
It is easy to see that Haack is a sort of philosophical granddaughter of Russell at least on this point.
In correspondence Dennis Monokroussos points out that "Anthony Kenny had a nice quip in reply to the Russell quotation. On page 2 of his edited work, Aquinas: A Collection of Critical Essays (London, 1969) (cited in Brian Davies, The Thought of Thomas Aquinas (Clarendon Press, 1992), p. 19), he says that the remark “comes oddly from a philosopher who took three hundred and sixty dense pages to offer a proof that 1 + 1 = 2.”
Exactly right. This is yet another proof that not every instance of (1a) above is an instance of sham reasoning or sham inquiry.
It is certainly false to say that, in general, it is unphilosophical or special pleading or an abuse of reason to seek arguments for a proposition antecedently accepted, a proposition the continuing acceptance of which does not depend on whether or not good arguments for it can be produced. But if we are to be charitable to Lord Russell we should read his assertion as restricted to propositions, theological and otherwise, that are manifestly controversial. So restricted, Russell's asseveration cannot be easily counterexampled, which is not to say that it is obviously true.
Thus I cannot simply cite the Incarnation doctrine and announce that we know this from revelation and are justified in accepting it whether or not we are able to show that it is rationally acceptable. For if it really is logically impossible then it cannot be true. If you say that it is actually true, hence possibly true whether or not we can explain how it is possible for it to be true, then you beg the question by assuming that it is actually true despite the opponent's arguments that it is logically contradictory.
It looks to be a stand-off.
One can imagine a Thomist giving the following speech.
My reasoning in defense of the Incarnation and other such doctrines as the Trinity is not sham despite the fact that I am irrevocably committed to these doctrines. It is a question of faith seeking understanding. I am trying to understand what I accept as true, analogously as Russell tried to understand in terms of logic and set theory what he accepted as true in mathematics. I am not trying to decide whether what I accept is true since I know it it to be true via an extraphilosophical source of knowledge. I am trying to understand how it could be true. I am trying to integrate faith with reason in a manner analogous to the way Russell sought to integrate arithmetic and logic. One can reason to find out new truths, but one can also reason, and reason legitimately, to penetrate intellectually truths one already possesses, truths the ongoing acceptance of which does not depend on one's penetrating them intellectually.
What then does the Russell-Haack objection amount to? It appears to amount to a rejection of certain extraphilosophical sources of knowledge/truth such as mystical experience, authority, and revelation. I have shown that Russell and his epigones cannot reject every extraphilosophical source of knowledge, else they would have to reject inner and outer sense. Can they prove that there cannot be any such thing as divine revelation? And if they cannot prove that, then their rejection of the possibility is arbitrary. If they say that any putative divine revelation has to validate itself by our lights, in our terms, to our logic, then that is just to reject divine revelation.
It looks to be a stand-off, then. Russell and his epigones are within their rights to remain within the sphere of immanence and not admit as true or real anything that cannot be certified or validated within that sphere by the satisfaction of the criteria human reason imposes. And their opponents are free to make the opposite decision: to open themselves to a source of insight ab extra.
It occurred to me this morning that there is a connection between the two.
Suppose a person asserts that abortion is morally wrong. Insofar forth, a bare assertion which is likely to elicit the bare counter-assertion, 'Abortion is not morally wrong.' What can be gratuitously asserted may be gratuitously denied without breach of logical propriety, a maxim long enshrined in the Latin tag Quod gratis asseritur, gratis negatur. So one reasonably demands arguments from those who make assertions. Arguments are supposed to move us beyond mere assertions and counter-assertions. Here is one:
Infanticide is morally wrong There is no morally relevant difference between abortion and infanticide Ergo Abortion is morally wrong.
Someone who forwards this argument in a concrete dialectical situation in which he is attempting to persuade himself or another asserts the premises and in so doing provides reasons for accepting the conclusion. This goes some distance toward removing the gratuitousness of the conclusion. THe conclusion is supported by reasons that are independent of the conclusion. But suppose he gave this argument:
Abortion is the deliberate and immoral termination of an innocent pre-natal human life Ergo Abortion is morally wrong.
The second argument is a clear example of petitio principii, begging the question. While the premise entails the conclusion, it does not support it with a reason independent of the conclusion. The argument 'moves in a circle' presupposing the very thing it needs to prove.
So the second 'argument' merely appears to be an argument: it us really just an assertion in the guise of an argument, and a gratuitous assertion at that. But what is gratuitously asserted can be gratuitously denied.
So there we have the connection between Quod gratis asseritur, gratis negatur and Petitio principii.
Alex L. writes, "I was interested in the post where you mentioned voting rationality. I've heard this argument as well — that the chance your vote will influence elections is minuscule, so it's not rational to vote."
But that is not the argument. The argument is not to the conclusion that it is not rational to vote, but that it is rational for many people to remain ignorant of past and present political events and other relevant facts and principles that they would have to be well-apprised of if they were to vote in a thoughtful and responsible manner.
What is at issue is not the rationality of voting but the rationality of political ignorance.
The reason it is rational for many people to remain politically ignorant is that one's vote will have little or no effect on the outcome. To become and remain politically knowledgeable as one must be if one is to make wise decisions in the voting booth takes a considerable amount of initial and ongoing work. I think Ilya Somin has it right:
. . . political ignorance is actually rational for most of the public, including most smart people. If your only reason to follow politics is to be a better voter, that turns out not be much of a reason at all. That is because there is very little chance that your vote will actually make a difference to the outcome of an election (about 1 in 60 million in a presidential race, for example). For most of us, it is rational to devote very little time to learning about politics, and instead focus on other activities that are more interesting or more likely to be useful.
And please note that if it is rational for many to remain politically ignorant, that is consistent with the rationality of others to become and remain politically knowledgeable. I gave three reasons for someone like me to be politically savvy.
First. My goal is to understand the world as best I can. The world contains political actors, political institutions, and the like. Therefore, in pursuit of my goal it is rational to study politics.
Second. Politics is interesting the way spectator sports are. Now I don't give a flying enchilada about the latter. Politics are my sports. In brief, staying apprised of political crapola is amusing and diverting and also has the salutary effect of reminding me that man is a fallen being incapable of dragging his sorry ass out of the dreck by his own power, or, in Kantian terms, that he is a piece of crooked timber out of which no straight thing ever has been or ever will be made.
Third. Knowledge of current events in the political sphere can prove useful when it comes to protecting oneself and one's family. Knowledge of the Obaminations of the current administration, for example, allows one to to plan and prepare.
It is also worth pointing out that while political ignorance is for many if not most citizens rational, that it not to say that it is good.
Note finally that if it is not rational for most of us to acquire and maintain the political knowledge necessary to vote wisely, election after election, that is not to say that it is not rational for most of us to vote. For one can vote the way most people do, foolishly. Consider those voters who vote a straight Democrat ticket, election after election. That takes little time and no thought and may well be more rational than not voting at all. Let's say you are a welfare recipient or a member of a teacher's union or an ambulance chaser. And let's assume you are voting in a local election. Then it might be in your interest, though it would not be for the common good, to vote a straight Dem ticket. It might well be rational given that no effort is involved.
There are those who love to expose and mock the astonishing political ignorance of Americans. According to a 2006 survey, only 42% of Americans could name the three branches of government. But here is an interesting question worth exploring:
Is it not entirely rational to ignore events over which one has no control and withdraw into one's private life where one does exercise control and can do some good?
I can vote, but my thoughtful vote counts for next-to-nothing in most elections, especially when it is cancelled out by the vote of some thoughtless and uninformed idiot. I can blog, but on a good day I will reach only a couple thousand readers worldwide and none of them are policy makers. (I did have some influence once on a Delta airline pilot who made a run for a seat in the House of Representatives.) I can attend meetings, make monetary contributions, write letters to senators and representatives, but is this a good use of precious time and resources? I think Ilya Somin has it right:
. . . political ignorance is actually rational for most of the public, including most smart people. If your only reason to follow politics is to be a better voter, that turns out not be much of a reason at all. That is because there is very little chance that your vote will actually make a difference to the outcome of an election (about 1 in 60 million in a presidential race, for example). For most of us, it is rational to devote very little time to learning about politics, and instead focus on other activities that are more interesting or more likely to be useful.
Is it rational for me to stay informed? Yes, because of my intellectual eros, my strong desire to understand the world and what goes on in it. The philosopher is out to understand the world; if he is smart he will have no illusions about changing it, pace Marx's 11th Thesis on Feuerbach.
Another reason for people like me to stay informed is to be able to anticipate what is coming down the pike and prepare so as to protect myself and my stoa, my citadel, and the tools of my trade. For example, my awareness of Obama's fiscal irresponsibility is necessary if I am to make wise decisions as to how much of my money I should invest in precious metals and other hard assets. Being able to anticipate Obaminations re: 'gun control' will allow me to buy what I need while it is still to be had. 'Lead' can prove to be useful for the protection of gold. And so on.
In brief, a reason to stay apprised of current events is not so that I can influence or change them, but to be in a position so that they don't influence of change me.
A third reason to keep an eye on the passing scene, and one mentioned by Somin, is that one might follow politics the way some follow sports. Getting hot and bothered over the minutiae of baseball and the performance of your favorite team won't affect the outcome of any games, but it is a source of great pleasure to the sports enthusiast. I myself don't give a damn about spectator sports. Politics are my sports. So that is a third reason for me to stay on top of what's happening.
All this having been said and properly appreciated, one must nevertheless keep things in perspective by bearing in mind Henry David Thoreau's beautiful admonition:
Read not The Times; read the eternities!
For this world is a vanishing quantity whose pomps, inanities, Obaminations and what-not will soon pass into the bosom of nonbeing. And you with it.
"Not enough evidence, God, not enough evidence!" (Bertrand Russell)
It may well be that our predicament is such as to disallow conclusive or even sufficient evidence of the truth about it. If Plato's Cave Allegory is apt, if it lays bare the truth of the human predicament, then it must be that the evidence that the cave is a cave and that there is an outer world, whether it be the evidence of someone's testimony or the evidence of one's own rare and fleeting experiences, is scant and flimsy and easily doubted and denied. What I merely glimpse on rare occasions I can easily doubt. One can also doubt what any church teaches for the simple reason that there are many churches and they contradict each other on many points of doctrine and practice. And the same goes for what I believe on the testimony of others.
We don't know that the human condition is a cave-like predicament along Platonic lines, but if it is then we have an explanation of the paucity of sufficient evidence of its being what it is. (By sufficient evidence for a proposition p I mean evidence that renders p more likely than its negation.)
It is vitally important to us whether God or some form of Transcendence exists, and whether a higher life is possible for us beyond the miserably short and indigent predicament in which we presently find ourselves. But it may be that the truth in this matter cannot be known here below, but only believed on evidence that does not make it more likely than not. It may be that our predicament is such as to make impossible sufficient evidence of the truth about it.
Do I violate an ethics of belief if I believe on insufficient evidence? But don't I also have a duty to myself to pursue what is best for myself? And seek my ultimate happiness? Why should the legitimate concern to not be wrong trump the concern to find what is salvifically right? Is it not foolish to allow fear of error to block my path to needed truth?
Lately I've heard bandied about the idea that to have faith is to pretend to know what one does not know. Now that takes the cake for dumbassery. One can of course pretend to know things one does not know, and pretend to know more about a subject than one does know. The pretence might be part of a strategy of deception in the case of a swindler or it might be a kind of acting as in the case of an actor playing a mathematician.
But in faith one does not pretend to know; one honestly faces the fact that one does not know and ventures beyond what one knows so as to gain access to a needed truth that by its very nature cannot satisfy the strictures that we moderns and post-moderns tend to build into 'know.'
Recognizing your praise for Critical Rationalism and Morris Raphael Cohen, I believe his page (and also the Karl Popper page) in my PDF Logic Gallery will interest you.
Of course, I hope the book's entire theme/content will also interest you.
Your comments will surely interest ME.
In these dark days of the Age of Feeling, when thinking appears obsolete and civilization is under massive threat from Islamism and its 'liberal' and leftist enablers, it seems fitting that I should repost with additions my old tribute to Morris Raphael Cohen. So here it is:
Tribute to Morris R. Cohen: Rational Thought as the Great Liberator
Morris Raphael Cohen (1880-1947) was an American philosopher of naturalist bent who taught at the City College of New York from 1912 to 1938. He was reputed to have been an outstanding teacher. I admire him more for his rationalism than for his naturalism. In the early 1990s, I met an ancient lady at a party who had been a student of Cohen's at CCNY in the 1930s. She enthusiastically related how Cohen had converted her to logical positivism, and how she had announced to her mother, "I am a logical positivist!" much to her mother's incomprehension.
We best honor a thinker by critically re-enacting his thoughts. Herewith, a passage from Cohen's A Preface to Logic, Dover, 1944, pp. 186-187:
…the exercise of thought along logical lines is the great liberation, or, at any rate, the basis of all civilization. We are all creatures of circumstance; we are all born in certain social groups and we acquire the beliefs as well as the customs of that group. Those ideas to which we are accustomed seem to us self-evident when [while?] our first reaction against those who do not share our beliefs is to regard them as inferiors or perverts. The only way to overcome this initial dogmatism which is the basis of all fanaticism is by formulating our position in logical form so that we can see that we have taken certain things for granted, and that someone may from a purely logical point of view start with the denial of what we have asserted. Of course, this does not apply to the principles of logic themselves, but it does apply to all material propositions. Every material proposition has an intelligible alternative if our proposition can be accurately expressed.
These are timely words. Dogmatism is the basis of all fanaticism. Dogmatism can be combatted by the setting forth of one's beliefs as conclusions of (valid) arguments so that the premises needed to support the beliefs become evident. By this method one comes to see what one is assuming. One can also show by this method that arguments 'run forward' can just as logically be 'run in reverse,' or, as we say in the trade, 'One man's modus ponens is another man's modus tollens.' These logical exercises are not merely academic. They bear practical fruit when they chasten the dogmatism to which humans are naturally prone.
In Cohen's day, the threats to civilization were Fascism, National Socialism, and Communism. Today the main threat is Islamo-totalitarianism, with a secondary threat emanating from the totalitarian Left. Then as now, logic has a small but important role to play in the defeat of these threats. The fanaticism of the Islamic world is due in no small measure to the paucity there of rational heads like Cohen.
But I do have one quibble with Cohen. He tells us that "Every material proposition has an intelligible alternative…" (Ibid.) This is not quite right. A material proposition is one that is non-logical, i.e., one that is not logically true if true. But surely there are material propositions that have no intelligible alternative. No color is a sound is not a logical truth since its truth is not grounded in its logical form. No F is a G has both true and false substitution-instances. No color is a sound is therefore a material truth. But its negation Some color is a sound is not intelligible if 'intelligible' means possibly true. If, on the other hand, 'intelligible' characterizes any form of words that is understandable, i.e., is not gibberish, then logical truths such as Every cat is a cat have intelligible alternatives: Some cat is not a cat, though self-contradictory, is understandable. If it were not, it could not be understood to be self-contradictory. By contrast, Atla kozomil eshduk is not understandable at all, and so cannot be classified as true, false, logically true, etc.
So if 'intelligible' means (broadly logically or metaphysically) possibly true, then it is false that "Every material proposition has an intelligible alternative . . . ."
Edith Stein, Finite and Eternal Being, tr. Reinhardt, ICS Publications, 2002, p. 22:
Reason would turn into unreason if it would stubbornly content itself with what it is able to discover with its own light, barring out everything which is made visible to it by a brighter and more sublime light.
Is it unreasonable to rely on reason alone, or is this exactly what reason demands? If the latter, how could reason validate its demand? Reason cannot validate itself by appeal to itself: A circular validation is no validation at all. So it is by a sort of transrational faith that reason relies on itself and accepts only what it can validate by its own lights. But if reason allows transrational faith in justification of itself, then it ought to be open to other transrational or suprarational sources of insight.
There is much depth in your short post on religion and reason from 6 May. Here are two points I often ponder about this topic:
First, I appreciate the difficulty of solving philosophical problems, but I wonder about the claim that they are insoluble (I suppose “insoluble” means “insoluble by humans alone”). If the problems are beyond mere human knowledge, how could we know this? One may inductively suspect insolubility by reflecting upon his experience of practicing philosophy, but how could he know the unknowable? If we can’t solve philosophical problems by philosophizing, then it seems we can’t conclude insolubility by philosophizing because this very conclusion would be a philosophical conclusion.
BV: I hold that the central problems of philosophy are most of them genuine, some of them humanly important, but all of them insoluble. And you are right, by 'insoluble' I mean insoluble by us or by beings of a similar cognitive architecture, ectypal intellects in Kant's jargon. Furthermore, pace Nicholas Rescher, I don't count a 'solution' that is relative to some set of background assumptions and cognitive values as a solution. Of course there are solutions in this sense. Nominalists solve the problem of univerals in one way, realists in another, conceptualists in a third, etc. But those are merely intramural solutions. What is wanted are solutions acceptable to all, solutions that hold ouside the walls of self-reinforcing enclaves of the like-minded.
You ask a very important question: How could one know that the central philosophical problems are insoluble? You yourself supplied the clue: by induction from philosophical experience. The best and the brightest have been at this game for thousands of years but not one single problem has been solved during this period, solved to the satisfaction of all competent practitioners. Everything is up for grabs, even the most elementary and picayune topics. Take a look at what is going one as we speak in the thread on logical form. Philosophers can't even agree on the most basic concepts of deductive logic. There is controversy everywhere. This is a plain fact.
The strife of systems and the ubiquity and longevity of controversy need explaining and I offer the insolubility thesis as the best explanation. Why haven't the problems been solved? Because they are insoluble. I agree with Benson Mates on this point. Of course, the following is an invalid argument form: Such-and-such has hitherto not been accomplished; ergo, such-and-such will never be accomplished. But then every inductive argument is invalid. Some inductive arguments, however, do quite reasonably support their conclusions.
But you can and should press your objection. If I maintain that the problems of philosophy are insoluble, then, given that the metaphilosophical problem of whether or not philosophical problems are soluble is a philosophical problem, it follows that the metaphilosophical problem is insoluble. Is this a difficult for my position? Not obviously. I simply 'bite the bullet' as they say. I accept that the meta problem is also insoluble.
In fact, the insolubility of the meta problem is further evidence of my thesis.
In other words, I am not dogmatizing. I am not claiming to know with certainty that the problems of philosophy are insoluble. I am not claiming to have solved the meta problem. I am merely claiming that the insolubility thesis is very reasonably maintained. Not every truth is such that we can know it to be true. With some truths the most we can expect here below is reasonable belief.
Compare God and the soul. I do not claim to know with certainty whether either exists. I claim merely that it it is reasonable to affirm both.
Second, I agree that it’s wise to intelligently practice religion and mysticism — which, by the way, rules out superstition and group-think! Take religion: religious practice does not exclude reason, as Mates’ quote implies. It is a false dilemma to say “One can seek truth either by reason or religion, but not both.” Why not both? If I try to lift a stone and realize I can’t manage alone, this would not entail that I can or should stop lifting. If a stronger person assists me, and I trust his assistance, I can still lift. He may request my help. He may even require that I give it my all, and I may grow from the effort. Likewise, intelligent religion requires reason.
Consider Christianity: The biblical conception of faith is “trust based on good reasons”. This point is clear in passages such as Hebrews 11:1 and 1 Peter 3:15. In the Gospels, Jesus himself reasons and encourages others to do the same. Christian faith calls for the whole self: heart, mind, soul, and strength.
I’d be interested in your thoughts on reason and intelligent religion.
BV: I basically agree with you. Reason in the end must confess its own infirmity. It cannot deliver on its promises. The truth-seeker must explore other avenues. Religion is one, mysticism is another.
