The Notion of a Cumulative Case

 In a comment thread Tony Hanson asked me if I had written a post on cumulative-case arguments.  After some digging, I located one that I had written 24 August 2004.  Here it is for what its worth. 

……………
 
Suppose you have a good reason R1 to do X. Then along comes a second good reason R2 to do X. Does R2 remove the justificatory force of R1? Obviously not. Does R2 leave the justificatory force of R1 unchanged? No again. Clearly, R2 augments the force of R1. Any additional good reasons R3, R4, . . . Rn, would of course only add to the justification for doing X. What we have here is a cumulative case for doing X, a case in which the justificatory force of the good reasons is additive.
 
A thorough discussion would have to distinguish between cumulative case arguments in which each reason is sufficient to justify the action envisaged, and cumulative case arguments in which one or more or all of the reasons are individually insufficient to justify the action envisaged.
 
Suppose each reason in a cumulative case argument is individually sufficient to justify the action envisaged. Then in what sense are the reasons additive? They are additive in that each additional sufficient reason provides an additional fail-safe mechanism. If an agent has many reasons each of which is both good and sufficient for doing X, then, if one of the reasons should turn out to be either bad or insufficient, then the other reasons are available to shoulder the justificatory burden.
 
Apply this to the Iraq war. One reason for going to war was the widely shared belief that Saddam had WMDs. Another was that he was a known sponsor of Palestinian Arab terrorists and a reasonably surmised sponsor of other terrorists. (On the second point, see Stephen F. Hayes, The Connection: How al-Qaeda's Collaboration with Saddam Hussein Has Endangered America, Harper Collins, 2004) A third was humanitarian: the liberation of the Iraqi people from a brutal dictator and his sons. A fourth was to enforce unanimous U.N. resolutions that this august body did not have the cojones to enforce itself. A fifth was to end the ongoing hostilities, e.g., Iraqi attacks on coalition warplanes. Even if no one of these reasons is sufficient to justify the invasion, the five taken together arguably provide good and sufficient reason for the action.
 
The strategy of ‘Divide and Conquer’ cannot be used against a cumulative case argument. Suppose Jack has several reasons for marrying Jill: she’s nubile and pretty, moneyed and witty; they are physically and psychologically compatible; they share the same values; she has beautiful eyes, and there is beauty at the opposite pole of her being as well. So Jack has nine good reasons. It simply won’t do to point out that each of them, taken singly, is insufficient to justify the marriage. A good reason is not the same as a sufficient reason. A good reason can be either sufficient or insufficient. What then are examples of bad reasons? A bad reason would be her having a police record, or her having a doctorate in biology when her doctorate is in mathematics.
 
The point is that several good, but individually insufficient, reasons can add up to a good and sufficient reason. If so, then ‘Divide and Conquer’ is a fallacious form of refutation. But that is what many leftists do when they oppose the Iraq war. Suppose that the cumulative case consists of R1, R2, and R3, each of which is insufficient by itself to justify doing X. The ‘Divide and Conquer’ objector wrongly infers ‘no reason’ from ‘insufficient reason.’ Thus he thinks that if R1 is insufficient, then R1 is no reason, and similarly for R2 and R3. He then concludes: no reason + no reason + no reason = no reason. He fails to appreciate the additivity of individually insufficient but good reasons, just as the typical poor person fails to appreciate the additivity of the small amounts of money he throws away on cigarettes, lottery tickets, and overpriced convenience store items.
For example, if a conservative gives liberation of the Iraqi people as a reason for the invasion, the leftie is likely to object: "But then why don’t we liberate the North Koreans?" This is an asinine response since it it is based on a failure to appreciate that the liberation reason is only one part of a cumulative case, not to mention the fact that an attempted liberation of the North Koreans could easily lead to nuclear war. Granting that liberating the Iraqi people is an insufficient reason for the war, it does not follow that it is no reason at all. It is a good reason which, though insufficient taken by itself, is part of a cumulative case which amounts to a good and sufficient reason for the war.
Another mistake that leftists make is to confuse a reason with a motive. They do this when they say that a proffered reason is not the real reason. A reason is a motive when it plays a motivating role within the psychic economy of an agent. Suppose Jack has available to him an objectively good reason R for marrying Jill. But Jack is not consciously or subconsciously aware of R. Obviously, R can play no role in the etiology of his envisaged action. Yet R remains an objectively good reason for performing the act in question. A good reason need not be a motivating reason, and a motivating reason need not be a good reason. The expression ‘real reason’ should be avoided because it is ambiguous as between good reason and motivating reason.
 
Suppose Bush II’s sole motive for invading Iraq was to avenge Saddam’s assasination attempt on his father, Bush I. Even on this wildly counterfactual assumption, there were good reasons for the invasion. For an action to be justified, all that is required is that there be objectively good reasons for the action; it is not necessary that the agent’s motives be objectively good reasons. Even if an agent is not justified in doing X – because he is either not aware of or motivated by the good reasons for doing X – the act itself (the act-type itself) can have justification. Our man Jack, for example, may be driven to marry Jill by his lust and nothing besides; but this does not entail that his marrying her lacks justification. Jack’s father might say to him: "Son, you made the right decision, but for the wrong reason." The rightness of the decision is due to the availability of good reasons even if horny Jack did not avail himself of them.

At this point an objector might maintain that what I am calling good reasons are simply ex post facto rationalizations.But a rationalization after the fact is not the same as a good reason that plays no motivating role in bringing about the fact. For a rationalization is a bad reason. Suppose Ali physically assaults Benjamin because Benjamin is a Jew and Ali believes that Jews are the "sons of pigs and monkeys." After the fact, A explains his behavior by saying that B insulted him. Suppose B did insult A. A is rationalizing after the fact as opposed to giving a good reason after the fact. B’s insulting of A did not give A a good reason for initiating physical violence against B.

Now let us suppose that Bush II’s sole motive for ordering the Iraq invasion was his desire to deprive Saddam of the WMDs that he, Bush, believed Saddam to possess. Suppose, plausibly, that the belief is false. In that case, Bush II’s motivating reason was not an objectively good reason – based as it was on a false belief – but it could still count as a subjectively good reason in this sense: he had a reason that was a good reason based on the information he had available to him at the time of the decision. I would then argue that the other reasons, which are objectively good, bear the justificatory burden.

An astonishing number of people, some of them intelligent, believe that the motivating reason for the Iraq invasion was the desire to secure access to Iraqi oil. But if that was the motivating reason, it is was a very bad reason since (i) the oil was flowing; (ii) starting a war with an opponent believed to have WMDs and known to have ignited oil wells in the past is clearly a stupid way to secure access to Iraqi oil; (iii) the projected cost of the war would be scarcely offset by the value of the oil secured; and (iv) deposing Saddam and his sons was not at all necessary to insure the flow of oil. I would argue that since this oil reason is so obviously bad, it is not reasonable to impute it to Bush and his advisers as the motivating reason for the invasion.

To sum up. The case for invading Iraq was a cumulative case. A cumulative case cannot be refuted by ‘Divide and Conquer.’ A good reason need not be a sufficient reason. A reason is not the same as a motive: there can be objectively good reasons for an action even if the agent of the action is not motivated by any of these reasons. To find good reasons after the fact is not to engage in ex post facto rationalization. This is because a rationalization is the providing of a bad reason.  But of course, liberals and leftists are so blinded by their passionate hatred of Bush II, that patient analysis of the foregoing sort will be lost on them.

 

On Smiting One’s Political Enemies

Tony Hanson e-mails from the once-great state of California whose governor-elect is once again Governor Moonbeam:

I see you had Berlin's essay in your library and reread it. I just wanted to say I don't think that we are in quite the bind you describe since there still seems to be a lot of room for some good rationally justified smiting, polemics and general political ass-kicking in spite of value pluralism. I'll make this very brief.

Defense of Polemics. I am sure you would agree that one's opponents may have all sorts of bad reasons for their positions, and (politely?) exposing them can make people more thoughtful, and may even enlighten them to the truth of value pluralism so much so that they may "flinch" too. Could this encourage comity?

That is a good point and I fully agree with it.  The pluralistic position, according to which no objective resolution satisfactory to all competent practioners is possible due to irresolvable value differences, is entirely consistent with the possibility of the fully objective exposure of bad arguments and empirical falsehoods on both sides.  Take abortion.  There are bad arguments on both sides of the debate, and almost everyone will agree that there are.   (I won't say what those bad arguments are lest I spark a meta-debate as to exactly which arguments on both sides are bad; but that there are bad arguments on both sides is uncontroversial.)   An argument can be objectively bad for a number of different reasons: it is logically invalid; rests on an empirically false premise; involves a weak analogy; commits an informal fallacy; is so murky and indistinct as to be insusceptible of evaluation, etc.  The essence of the pluralistic position is that once all the bad arguments on both sides are set aside, one arrives at a set of 'good' arguments which, however, do not resolve the issue for an  impartial observer.

I would quibble, though, with your use of 'polemics.'  From the Greek polemos, it means strife, struggle, war.  So we can define polemics as verbal warfare, warfare at the level of ideas.  There needn't be anything polemical about pointing out to an opponent that one of his arguments falls short of an objective standard such as the one represented by formal logic.  Here there is the possibility of convincing the opponent (assuming he is sincere, intelligent, etc.) because the cognitive values that come into play (truth, clarity, logical coherence, etc.) are agreed upon.

Defense of War and Smiting.  You said, "Suppose further … that this value difference that divides them cannot be objectively resolved to the satisfaction of both parties by appeal to any empirical fact or by any reasoning or by any combination of the two." Say you are arguing with a Fascist or radical libertarian (who thinks property rights are absolute), and no empirical fact or reasoning satisfies them In other words, they are unreasonable.

But if you say that the radical libertarian is unreasonable, what are your criteria of reasonability or rationality?  I reject the radical libertarian position on property rights and I get the impression that you do as well.  But from his point of view, his stance is reasonable in that it is rationally derivable from certain axioms he accepts.  Is there some plain empirical fact that he fails to take cognizance of, or some rule of logic that he flouts?  When you  say that the radical libertarian is unreasonable, aren't you just rejecting his scheme of values? He places an absolute, inviolable, value on the individual and his property and refuses to admit that there are any competing values that would tend to have a relativizing effect.  Consider an eminent domain dispute.  Farmer Jones has worked hard all his life and owns 100 acres.  The Feds want to buy from him a strip of land for a much-needed road that cannot be placed anywhere else. Jones refuses to sell.  Even if he agrees that there is such a thing as the common good, he refuses to concede that it has the power to limit the absoluteness of his property right.

When you say that Jones is unreasonable, what you are doing is pitting your value-based conception of reasonableness against his.  But then my point goes through, which was that disputes like this are objectively irresolvable because rooted in value disputes which are objectively irresolvable.

Seems like its time for the Converse Clausewitz Principle [Politics is war conducted by other means]. Well, you can of course work to defeat libertarians in the political arena (though they do a pretty good job of this themselves, which is why I follow Medved in calling them 'losertarians.')  But the issue concerns your rational warrant for "unflinchingly" opposing them.  What makes you so cocksure that you are right and they are wrong?

Further, it seems a distinction needs to be made between the priority of a value, and the weight (or  height?) of the priority. Two people could prioritize security over liberty, but one would be prepared to sacrifice a lot more liberty for security than the other. The extremist gives his value too much weight, obviously; but it also seems one can be objectively wrong about the weight of the prioritized value, and not be an extremist. Invoking Aristotle might be helpful. Though one might not be a complete coward (or extremist), one might miss the mark with respect to courage and be a little cowardly, and so on with the various values. Moreover, it might not be possible to come to an agreement by using facts and reason, to what "hitting the mark" is, but you know it misses. Someone might have a different intuition on what hitting the mark is, or the target might be a large one allowing for disagreement, but it still might be worth trusting your sense of "tone," and fighting for it.

I agree that if value V1 takes priority over value V2, there remains the question of how much higher up in the axiological hierarchy V1 is.  Patrick Henry said, "Give me liberty or give me death."  He apparently valued his liberty over his very life.  Would you call him an extremist?  If yes, then what is wrong with being an extremist?  If he is placing an inordinate value on liberty, how do you show that?  Or take the Obama liberal who is willing to sacrifice his liberty for (the promise of) cradle-to-grave security and material comfort.  How do you show in an objective manner that the liberal places too much value on security and not enough on liberty?  You simply assert that "one can be objectively wrong about the weight of the prioritized value." Gratuitous assertions, however, elicit gratuitous counterassertions in response.

Tea Partiers object to the liberty-encroaching governmental overreach of the Obama gang.  (Case in point: the 'individual mandate' of Obamacare which forces citizens to buy health insurance.)  The political conflict is rooted in a deep value conflict.  How resolve it?

I don't see how Aristotle helps in this.  I would also point out that he was talking about virtues, not values, which are a different animal entirely and didn't come into philosophical currency until the 19th century.  A virtue is a habit (hexis, habitus), a dispositional feature of an agent; a value is . . . well what exactly is a value?  An abstract or ideal object of some sort?

The ComBox is open to give Hanson an opportunity to reply.  Others may chime in as well, but only if their comments are well-informed, intelligent, and stick precisely to the topic under discussion, what he says and what I say here and in the post that Hanson in replying to.  I simply delete comments I consider to be substandard. 

Visualize Using Your Turn Signals

Visualize This is one of my favorite bumper stickers, and not just because there are all too many motorists clogging the roads who seem unacquainted with the function of turn signals. The sticker is a parody of ‘Visualize World Peace’ (‘Visualize Whirled Peas’). Visualizing something as nebulous and utopian as world peace is about as pointless as the sort of visualizing going on in John Lennon’s silly ditty, “Imagine.”

If you want to improve the world, try visualizing some concrete action that it is in your power to perform such as letting a motorist enter your lane. Better, visualize an entire day in which you gratuitously offend no one in word or deed. Then take the next step: visualize an entire day in which you gratuitously offend no one in word or deed, and entertain no negative thoughts to boot. In the end, there is only one person over whose behavior you have any real control, namely, yourself. So if you are serious about improving the world, you can start with that guy. If you desire peace in the world, begin by making war against your lower self.

I am not saying that this is sufficient for world peace, but it may well be necessary.

‘One Man’s Terrorist is Another Man’s Freedom Fighter’

Often and thoughtlessly repeated, 'One man's terrorist in another man's freedom fighter' is one of those sayings that cry out for logical and philosophical analysis. Competent analysis will show that clear-thinking persons ought to avoid the saying.

Note first that while freedom is an end, terror is a means. So to call a combatant a terrorist is to say something about his tactics, his means for achieving his ends, while to call a combatant a freedom fighter is to say nothing about his tactics or means for achieving his ends. It follows that one and the same combatant can be both a terrorist and a freedom fighter. For one and the same person can employ terror as his means while having freedom as his end.

Excellent Advice on Non-Violence from Simone Weil

Simone Weil, Gravity and Grace, tr. Emma Craufurd, Routledge 1995, p. 77, emphasis added.

Non-violence is no good unless it is effective. Hence the young man's question to Ghandi about his sister. The answer should have been: use force unless you are such that you can defend her with as much chance of success without violence. Unless you possess a radiance of which the energy (that is to say, the possible effectiveness in the most material sense of the word) is equal to that contained in your muscles.

We should strive to become such that we are able to be nonviolent.

This also depends on the adversary.

The Post-Modern Protocols of War: Victor Davis Hanson on the Gaza Rules

Required reading from the pen of Victor Davis Hanson.  Since I cannot do better than him, I will simply provide excerpts of five key points he makes.  Be sure and read the whole piece.  Here are Hanson's Gaza rules in his words but with material omitted:

First is the now-familiar Middle East doctrine of proportionality. Legitimate military action is strangely defined by the relative strength of the combatants. World opinion more vehemently condemns Israel's countermeasures, apparently because its rockets are far more accurate and deadly than previous Hamas barrages that are poorly targeted and thus not so lethal.

Second, intent in this war no longer matters. Every Hamas unguided rocket is launched in hopes of hitting an Israeli home and killing men, women and children. Every guided Israeli air-launched missile is targeted at Hamas operatives, who deliberately work in the closest vicinity to women and children.

Third, culpability is irrelevant. The "truce" between Israel and Hamas was broken once Hamas got its hands on new stockpiles of longer-range mobile rockets — weapons that are intended to go over Israel's border walls.

Yet, according to the Gaza rules, both sides always deserve equal blame. Indeed, this weird war mimics the politically correct, zero-tolerance policies of our public schools, where both the bully and his victim are suspended once physical violence occurs.

Fourth, with instantaneous streaming video from the impact sites in Gaza, context becomes meaningless. Our attention is glued to the violence of the last hour, not that of the last month that incited the war.

Israel withdrew from Gaza in 2005 to great expectations that the Palestinians there would combine their new autonomy, some existing infrastructure left behind by the Israelis, Middle East oil money and American pressure for free and open elections to craft a peaceful, prosperous democracy.

Fifth and finally, victimization is crucial. Hamas daily sends barrages into Israel, as its hooded thugs thump their chests and brag of their radical Islamic militancy. But when the payback comes, suddenly warriors are transmogrified into weeping victims, posing teary-eyed for the news camera as they deplore "genocide" and "the Palestinian Holocaust." At least the Japanese militarists did not cry out to the League of Nations for help once mean Marines landed on Iwo Jima.

Weakness Does Not Justify

Might does not make right, but neither does impotence or relative weakness. That weakness does not justify strikes me as an important principle, but I have never seen it articulated. The power I have to kill you does not morally justify my killing you. In a slogan: Ability does not imply permissibility.  My ability to kill, rape, pillage & plunder does not confer moral justification on my doing these things.  But if you attack me with deadly force of magnitude M and I reply with deadly force of magnitude 10 x M, your relative weakness does not supply one iota of moral justification for your attack, nor does it subtract one iota of moral justification from my defensive response.  If I am justified in using deadly force against you as aggressor, then the fact that my deadly force is greater than yours does not (a) diminish my justification in employing deadly force, nor does it (b) confer any justification on your aggression.

Suppose a knife-wielding thug commits a home invasion and attacks a man and his family. The man grabs a semi-automatic pistol and manages to plant several rounds in the assailant, killing him. It would surely be absurd to argue that the disparity in lethality of the weapons involved diminishes the right of the pater familias to defend himself and his family.

The principle that weakness does not justify can be applied to the Israeli-Hezbollah conflict from the summer of 2006 as well as to the current Israeli defensive operations against the terrorist entity, Hamas.  The principle ought to be borne in mind when one hears leftists, those knee-jerk supporters of any and every 'underdog,' start spouting off about 'asymmetry of power' and 'disproportionality.'
