One aspect of contemporary scientism is the notion that great insights are to be gleaned from neuroscience about the mind and its operations. If you want my opinion, the pickin's are slim indeed and confusions are rife. This is your brain on prayer:
A test subject is injected with a dye that allows the researcher to study brain activity while the subject is deep in prayer/meditation. The red in the language center and frontal lobe areas indicates greater brain activity when the subject is praying or meditating as compared to the baseline when he is not. But when atheists "contemplate God" — which presumably means when they think about the concept of God, a concept that they, as atheists, consider to be uninstantiated — "Dr. Newberg did not observe any of the brain activity in the frontal lobe that he observed in religious people."
The upshot?
Dr. Newberg concludes that all religions create neurological experiences, and while God is unimaginable for atheists, for religious people, God is as real as the physical world. "So it helps us to understand that at least when they [religious people] are describing it to us, they are really having this kind of experience… This experience is at least neurologically real."
First of all, why do we need a complicated and expensive study to learn this? It is well-known that serious and sincere practioners of religions will typically have various experiences as a result of prayer and meditation. (Of course most prayer and meditation time is 'dry' — but experiences eventually come.) The reality of these experiences as experiences cannot be doubted from the first-person point of view of the person who has them. There is no need to find a neural correlate in the brain to establish the reality of the experience qua experience. The experiences are real whether or not neural correlates can be isolated, and indeed whether or not there are any.
Suppose no difference in brain activity is found as between the religionists and the atheists when the former do their thing and the latter merely think about the God concept. (To call the latter "contemplating God" is an absurd misuse of terminology.) What would that show? Would it show that there is no difference between the religionists' experiences and the atheists'? Of course not. The difference is phenomenologically manifest, and, as I said, there is no need to establish the "neurological reality" of the experiences to show that they really occur.
Now I list some possible confusions into which one might fall when discussing a topic like this.
Confusion #1: Conflating the phenomenological reality of a religious experience as experienced with its so-called "neurological reality." They are obviously different as I've already explained.
Confusion #2: Conflating the religious experience with its neural correlate, the process in the brain or CNS on which the experience causally depends. Epistemically, they cannot be the same since they are known in different ways. The experience qua experience is known with certainty from the first-person point of view. The neural correlate is not. One cannot experience, from the first-person point of view, one's own brain states as brain states. Ontically, they cannot be the same either, and this for two sorts of reasons. First, the qualitative features of the experiences cannot be denied, but they also cannot be identified with anything physical. This is the qualia problem. Second, religious/mystical experiences typically exhibit that of-ness or aboutness, that directedness-to-an-object, that philosophers call intentionality. No physical states have this property.
Confusion #3: Conflating a religious entity with its concept, e.g., confusing God with the concept of God. This is why it is slovenly and confused to speak of "contemplating God" when one is merely thinking about the concept of God. The journalist and/or the neuroscientist seem to be succumbing to this confusion.
Confusion #4: Conflating an experience (an episode or act of experiencing) with its intentional object. Suppose one feels the presence of God. Then the object is God. But God is not identical to the experience. For one thing, numerically different experiences can be of the same object. The object is distinct from the act, and the act from the object. The holds even if the intentional object does not exist. Suppose St Theresa has an experience of the third person of the Trinity, but there is no such person. That doesn't affect the act-object structure of the experience. After all, the act does not lose its intentional directedness because the object does not exist.
Confusion #5: Conflating the question whether an experience 'takes an object' with the question whether the object exists.
Confusion #6: Conflating reality with reality-for. There is no harm is saying that God is real for theists, but not real for atheists if all one means is that theists believe that God is real while atheists do not. Now if one believes that p, it does not follow that p is true. Likewise, if God is real for a person it doesn't follow that God is real, period. One falls into confusion if one thinks that the reality of God for a person shows that God is real, period.
We find this confusion at the end of the video clip. "And if God only exists in our brains, that does not mean that God is not real. Our brains are where reality crystallizes for us."
This is confused nonsense. First of all God cannot exist in our brains. Could the creator of the universe be inside my skull? Second, it would also be nonsense to say that the experience of God is in our brains for the reasons give in #2 above. Third, if "God exists only in our brains" means that the experience of God is phenomenologically real for those who have it, but that the intentional object of this experience does not exist, then it DOES mean that God is not real.
Confusion #7: Conflating the real with the imaginable. We are told that "God is unimaginable for atheists." But that is true of theists as well: God, as a purely spiritual being, can be conceived but not imagined. To say that God is not real is not to say that God is unimaginable, and to say that something (a flying horse, e.g.) is imaginable is not to say that it is real.
What I am objecting to is not neuroscience, which is a wonderful subject worth pursuing to the hilt. What I am objecting is scientism, in the present case neuroscientism, the silly notion that learning more and more about a hunk of meat is going to give us real insight into the mind and is operations and is going to solve the philosophical problems in the vicinity.
What did we learn from the article cited? Nothing. We don't need complicated empirical studies to know that religious experiences are real. What the article does is sow seeds of confusion. One of the confusions the article sows is that the question of the veridicality of religious experiences can be settled by showing their "neurological reality." Neither the phenomenological nor the neurological reality of the experience qua experience entails the reality of the object of the experience.
Genuine science cannot rest on conceptual foundations that are thoroughly confused.
This is the fourth in a series of posts on Thomas Nagel's Mind and Cosmos (Oxford 2012). The posts are conveniently collected under the rubric Nagel, Thomas. Before proceeding with my account of Chapter 4, I will pause in this entry to consider Elliot Sober's serious, substantial, and sober Boston Review review. Sober's sobriety lapses only in the subtitle (which may have been supplied by the editor): "Ending Science as We Know It."
According to Sober, Nagel " . . . argues that evolutionary biology is fundamentally flawed and that physics also needs to be rethought—that we need a new way to do science." This seems to me to misrepresent Nagel's project. His project is not to "end science as we know it" but to indicate the limits of scientific explanation. A legitimate philosophical task is to investigate the limits of even the most successful sciences. (4) Now, to investigate and point out the limits of evolutionary biology and physics is not to argue that they are "fundamentally flawed." They do what they are supposed to do, and the fact that they do not, or cannot, explain certain phenomena that certain scientistically inclined people would like them to explain, is no argument against them. After all, physics cannot explain the proliferation of living species, but that is no argument against physics. If evolutionary biology cannot explain how consciousness arises in certain organisms or the objectively binding character or normative judgments, that is no argument against evolutonary biology. To oppose Darwinian imperialism as Nagel does is not to oppose Darwinism. To suppose that every gap in our understanding can be filled with a Darwinian explanation is rightly ridiculed as "Darwinism of the gaps." (127)
Nagel's targets are not existing successful sciences. He tells us right at the outset what his target is (bolding added): "My target is a comprehensive, speculative world picture that is reached by extrapolation from some of the discoveries of biology, chemistry, and physics — a particular naturalistic Weltanschauung that postulates a hierarchical relation among the subjects of those sciences, and the completeness in principle of an explanation of everything in the universe through their unification." (4) He goes on to characterize this worldview as "materialist reductionism" and "reductive materialism."
Nagel is therefore not opposing any science but rather a philosophical position, materialist reductionism, that is reached by a speculative-philosophical extrapolation from some of the results of the sciences.
Although Nagel admits that there are some brute facts, mind, the intelligibility of the world, and the fact that there are conscious organisms (45) are not among them. Mind is not an accident or fluke (16) and "The intelligibility of the world is no accident." One of the limits of current evolutionary theory is that it cannot explain why these remarkable fact are non-accidental. Sober does not understand why, if some facts are brute, the remarkable facts of mind, intelligibilty and consciousness are not among them:
My philosophical feelings diverge from Nagel’s. I think that Beethoven’s existence is remarkable, but I regard it as a fluke. He could easily have failed to exist. Indeed, my jaded complacency about Beethoven scales up. I don’t think that life, intelligence, and consciousness had to be in the cards from the universe’s beginning. I am happy to leave this question to the scientists. If they tell me that these events were improbable, I do not shake my head and insist that the scientists must be missing something. There is no such must. Something can be both remarkable and improbable.
Sober seems to be imputing to Nagel the following argument:
What is remarkable cannot be improbable.
Life, consciousness, reason, etc. are remarkable
Therefore
Life, consciousness, reason, etc. cannot be improbable.
Now this is an unsound argument, of course: Beethoven's existence was remarkable but improbable. But this is not the way Nagel is arguing. He needn't be read as denying that there is an element of chance in the appearance of Beethoven, a particular instance of life, consciousness, and reason. His point is rather that consciousness and reason in general cannot be cosmic accidents. Sober ignores what is specific to reason, and views it as just another remarkable fact. Nagel's actual argument (see p. 86) is rather along these lines:
1. There are organisms capable of reason.
2. The possibility of such beings must have been there from the beginning.
3. This possibility, however, must be grounded in and explained by the nature of the cosmos.
4. What's more, the nature of the cosmos must explain not only the possibiity but also the actuality of rational animals: their occurrence cannot be a brute fact or accident.
I take Nagel to be maintaining that the eventual existence of some rational beings or other is no accident — which is consistent with maintaining that there is an element of chance involved in the appearance of any particular instance of reason such as Beethoven.
Of course, Sober will still balk. Why can't reason be a fluke? Even if we grant Nagel that the intelligibility of nature could not have been a fluke or brute fact, how does it follow that the actual existence of some rational beings or other, beings capable of 'glomming onto' the world's intelligible structure, is not a fluke? In a later post I will try to beef up Nagel's argument so that it can meet this demand.
For now, though, we have a stand-off. Nagel has this deep sense, which I share, that "rational intelligibility is at the root of the natural order . . . ." (17) Sober in his sobriety does not share that sense.
There is more to Sober's criqiue than this, but this is enough for today.
If someone questions your right to have an opinion about abortion if you are man, say Arguments don't have testicles.
In section 53 of The Foundations of Arithmetic, Gottlob Frege famously maintains that
. . . existence is analogous to number. Affirmation of existence is in fact nothing but denial of the number nought. Because existence is a property of concepts the ontological argument for the existence of God breaks down. (65)
Frege is here advancing a double-barreled thesis that splits into two subtheses.
ST1. Existence is analogous to number.
ST2. Existence is a property (Eigenschaft) of concepts and not of objects.
In the background is the sharp distinction between property (Eigenschaft) and mark (Merkmal). Three-sided is a mark of the concept triangle, but not a property of this concept; being instantiated is a property of this concept but not a mark of it. The Cartesian-Kantian ontological argument "from mere concepts" (aus lauter Begriffen), according to Frege, runs aground because existence cannot be a mark of any concept, but only a property of some concepts. And so one cannot validly argue from the concept of God to the existence of God.
Existence as a property of concepts is the property of being-instantiated. We can therefore call the Fregean account of existence an instantiation account.
My concern in this entry is the logical relation between the subtheses. Does the first entail the second or are they logically independent? There is a clear sense in which (ST1) is true. Necessarily, if horses exist, then the number of horses is not zero, and vice versa. 'So 'Horses exist' is logically equivalent to 'The number of horses is not zero.' This is wholly unproblematic for those of us who agree that there are no Meinongian nonexistent objects. But note that, in general, equivalences, even logical equivalences, do not sanction reductions or identifications. So it remains an open question whether one can take the further step of reducing existence to instantiation, or identifying existence with instantiation, or even eliminating existence in favor of instantiation.
(ST1), then, is unproblematically true if understood as expressing the following logical equivalence: 'Necessarily Fs exist iff the number of Fs is not zero.' My question is whether (ST1) entails (ST2). Peter van Inwagen in effect denies the entailment by denying that the 'the number of . . . is not zero' is a predicate of concepts:
I would say that, on a given occasion of its use, it predicates of certain things that they number more than zero. Thus, if one says, 'The number of horses is not zero,' one predicates of horses that they number more than zero. 'The number of . . . is not zero' is thus what some philosophers have called a 'variably polyadic' predicate. But so are many predicates that can hardly be regarded as predicates of concepts. The predicates 'are ungulates' and 'have an interesting evolutionary history,' for example, are variably polyadic predicates. When one says, 'Horses are ungulates' or 'Horses have an interesting evolutionary history' one is obviously making a statement about horses and not about the concept horse. ("Being, Existence, and Ontological Commitment," pp. 483-484)
It is this passage that I am having a hard time understanding. It is of course clear what van Inwagen is trying to show, namely, that the Fregean subtheses are logically independent and that one can affirm the first without being committed to the second. One can hold that existence is denial of the number zero without holding that existence is a property of concepts.
But I am having trouble with the claim that the predicate 'the number of . . . is not zero' is 'variably polyadic' and the examples van Inwagen employs. 'Robbed a bank together' is an example of a variably polyadic predicate. It is polyadic because it expresses a relation and it is variably polyadic because it expresses a family of relations having different numbers of arguments. For example, Bonnie and Clyde robbed a bank together, but so did Ma Barker and her two boys, Patti Hearst and three members of the ill-starred Symbionese Liberation Army, and so on. (Example from Chris Swoyer and Francesco Orilia.)
Now when I say that the number of horses is not zero, what am I talking about? It is plausible to say that I am talking about horses, not about the concept horse. What I don't understand is why van Inwagen says that 'the number of . . . is not zero' is a variably polyadic predicate. As far as I can see, it is not even polyadic, let alone variably polyadic. What is the relation that the predicate expresses, and why is that relation multigrade? I grant that there are indefinitely many ways the number of horses could be not zero: there could be one horse, two, three, and so on. But what is the relation between or among horses that this supposedly polyadic predicate expresses?
'. . .exist(s)' is monadic. It expresses no relation. Why not say the same about 'such that their number is not zero'?
Now consider 'are ungulates.' If an ungulate is just a mammal with hooves, then I fail to see how 'are ungulates' is polyadic, let alone variably polyadic. 'Are hooved mammals' is monadic.
The other example is 'Horses have an interesting evolutionary history.' This sentence is clearly not about the concept horse. But it is not about any individual horse either. Consider Harry the horse. Harry has a history. He was born in a certain place, grew up, was bought and sold, etc. and then died at a certain age. He went through all sorts of changes. But Harry didn't evolve, and so he had no evolutionary history. No individual evolves; populations evolve:
Evolutionary change is based on changes in the genetic makeup of populations over time. Populations, not individual organisms, evolve. Changes in an individual over the course of its lifetime may be developmental (e.g., a male bird growing more colorful plumage as it reaches sexual maturity) or may be caused by how the environment affects an organism (e.g., a bird losing feathers because it is infected with many parasites); however, these shifts are not caused by changes in its genes.
While it would be handy if there were a way for environmental changes to cause
adaptive changes in our genes — who wouldn't want a gene for malaria resistance
to come along with a vacation to Mozambique? — evolution just doesn't work that
way. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population.
'Horses have an interesting evolutionary history,' then, is not about the concept horse or about any individual horse. The predicate in this sentence appears to be non-distributive or collective. It is like the predicate in 'Horses have been domesticated for millenia.' That is certainly not about the concept horse. No concept can be ridden or made to carry a load. But it is also not about any individual horse. Not even the Methuselah of horses, whoever he might be, has been around for millenia.
A predicate F is distributive just in case it is analytic that whenever some things are F, then each is F. Thus a distributive predicate is one the very meaning of which dictates that if it applies to some things, then it applies to each of them. 'Blue' is an example. If some things are blue, then each of them is blue.
If a predicate is not distributive, then it is non-distributive (collective). If some Occupy-X nimrods have the building surrounded, it does not follow that each such nimrod has the building surrounded. If some students moved a grand piano into my living room, it does not follow that each student did. If bald eagles are becoming extinct, it does not follow that each bald eagle is becoming extinct. Individual animals die, but no individual animal ever becomes extinct. If the students come from many different countries, it does not follow that each comes from many different countries. If horses have an interesting evolutionary history, it does not follow that each horse has an interesting evolutionary history.
My problem is that I don't understand why van Inwagen gives the 'Horses have an interesting evlutionary history' example when he is committed to saying that each horse exists. His view , I take it, is that 'exist(s)' is a first-level non-distributive predicate. 'Has an interesting evolutionary history,' however, is a first-level non-distributive predicate. Or is it PvI's view that 'exist(s)' is a first-level non-distributive predicate?
Either I don't understand van Inwagen's position due to some defect in me, or it is incoherent. I incline toward the latter. He is trying to show that (ST1) doe not entail (ST2). He does this by giving examples of predicates that are first-level, i.e., apply to objects, but are variably polyadic as he claims 'the number of . . . is not zero' is variably polyadic. But the only clear example he gives is a predicate that is non-distributive, namely 'has an interesting evilutionary history.' 'Horses exist,' however, cannot be non-distributive. If some horses exist, then each of them exists. And if each of them exists, then 'exists' is monadic, not polyadic, let alone variably polyadic.
The ComBox is open if there is anyone who knows this subject and has read PvI's paper and can set me straight.
Documented by VDH. His mojo's risin' and with it his mendacity. Yes, they played politics on Libya.
Here is the video clip of Obama lying to Romney and the rest of us in their second debate. Obama lies when he claims that on the Arizona law (S. B. 1070) law enforcement officers can stop people whom they merely suspect of being undocumented workers. Obama has told this lie before.
The details are in an earlier post which I now reproduce:
Debra Saunders' article begins:
President Barack Obama hailed the Supreme Court's 5-3 decision Monday that struck down most of Arizona's 2010 immigration law. In a statement released by the White House, however, the president said that he remains "concerned about the practical impact of the remaining provision of the Arizona law that requires local law enforcement officials to check the immigration status of anyone they even suspect to be here illegally."
All eight voting members of the Supreme Court upheld this provision, which requires
that Arizona cops try to determine the immigration status of individuals who have been stopped for reasons not involving immigration.
Please note the difference between what the president is quoted as saying and what Saunders correctly reports the S.B. 1070 provision as requiring. The law requires "that Arizona cops try to determine the immigration status of individuals who have been stopped for reasons not involving immigration." President Obama of course knows this. So Obama lied in his statement when he said that "the Arizona law that requires local law enforcement officials to check the immigration status of anyone they even suspect to be here illegally."
Obama's egregious misrepresentation has been repeated time and again by leftists over the last two years. See my 1 June 2010 post, The Misrepresentations of Arizona S. B. 1070 Continue. Other
of my 1070 posts are to be found in the Arizona category.
Why are leftists so mendacious? Because in their scheme the glorious end justifies the scurrilous means.
Don't forget to read the rest of Saunders' article.
Here. Amazingly, yet another Keroauc biography has been published, this time by Johnson. Just what neither the world nor I need. But being a 'completist' I'll probably acquire this one too.

It was 42 years ago today that I first began keeping a regular journal. Before that, as a teenager, I kept some irregular journals. Why maintain a journal? When I was 16 years old, my thought was that I
didn't want time to pass with nothing to show for it. That is still my thought. The unrecorded life is not worth living. For we have it on good authority that the unexamined life is not worth living, and how examined could an undocumented life be?
The maintenance of a journal aids mightily in the project of self-individuation. Like that prodigious journal writer Søren Kierkegaard, I believe we are here to become actually the individuals we are potentially. Our individuation is not ready-made or given, but a task to be accomplished. The world is a vale of soul-making; we are not here to improve it, but to be improved by it.
Henry David Thoreau, another of the world's great journal writers, said in Walden that "Most men live lives of quiet desperation." I would only add that without a journal, one's life is one of quiet dissipation. One's life dribbles away, day by day, unreflected on, unexamined, unrecorded, and thus fundamentally unlived. Living, for us, is not just a biological process; it is fundamentally a spiritual unfolding. To mean anything it has to add up to something, and that something cannot be expressed with a dollar sign.
I have always had a horror of an unfocused existence. In my early twenties, I spoke of the supreme desideratum of a focused existence. What bothered me about the people around me, fellow students in particular, was the mere aestheticism of their existence: their aimless drifting hither and yon, their lack of commitment, their unseriousness, their refusal to engage the arduous task of self-definition and self-individuation, their willingness to be guided and mis-guided by social suggestions. In one's journal one collects and re-collects oneself; one makes war against the lower self and the
forces of dispersion.
Another advantage to a journal and its regular maintenance is that one thereby learns how to write, and how to think. An unwritten thought is still a half-baked thought: proper concretion is achieved only by expressing thoughts in writing and developing them. Always write as well as you can, in complete sentences free of grammatical and spelling errors. Develop the sentences into paragraphs, and if the Muse is with you those paragraphs may one day issue in essays, articles, and chapters of books.
Finally, there is the pleasure of re-reading from a substantial temporal distance. Two years ago I began re-reading my journal in order, month by month, at a 40 year distance. So of course now I am up to October 1972. 40 Years from now I will be at the present, or dead. One.
Good music, dreadful politics. Excerpt:
Unfortunately, the entire event was marred by the hard Left narrative particularly voiced in the most offensive manner by two artists, Tom Morello and Ry Cooder. At least Cooder is a real musician, but that does not excuse his behavior and his leftist rants delivered both in asides and in the rewriting of Guthrie’s lyrics. Cooder sang a little known Guthrie song written towards the end of WW II about how the fascists would all lose. Cooder commented, to great applause from the leftist audience, that we won that fight, but the fascists were still here, and he knew they would be defeated on election day. Singing Guthrie’s “Vigilante Man,” about hired thugs of the coal companies in the early 20th Century, Cooder changed a lyric to make it about the Trayvon Martin case. He could have grown up to be President, he said, “but he was killed by a vigilante man.” Then he sang a new verse about how those in the audience should not tell anyone that they attended the concert, or they too might be killed!
Does Ry Cooder really believe that paying an average of $100 for a Kennedy Center concert could lead anyone to be harmed, not to say murdered? Doesn’t he know that by now, Woody Guthrie is a celebrated national hero, honored and revered by many, and no kind of danger to anyone who sings his songs?
How Cooder could be such an idiot is beyond me, but then he is not atypical. Artists, actors, and musicians hang with their own left-leaning ilk and are never exposed to conservative or libertarian points of view. They reinforce each others' prejudices. Denouncing bigotry in others, they exemplify it in excelsis. Masters of psychological projection, they cannot face what they project into others. They can emote in all sorts of creative ways, but they cannot think.
Play Ry, play. But shut up about politics until you learn something. Two favorites of mine: Yellow Roses. He'll Have to Go.
Radosh reports that Arlo Guthrie is a registered Republican and libertarian. At least he has his head screwed on Right. City of New Orleans. A great piece of Americana.
This is the third in a series of posts on Thomas Nagel's Mind and Cosmos (Oxford 2012). The first is an overview, and the second addresses Nagel's reason for rejecting theism. This post will comment on some of the content in Chapter 4, "Cognition."
In Chapter 4, Nagel tackles the topic of reason, both theoretical and practical. The emphasis is on theoretical reason, with practical reason receiving a closer treatment in the following chapter entitled "Value."
We have already seen that consciousness presents a problem for evolutionary reductionism due to its irreducibly subjective character. (For some explanation of this irreducibly subjective character, see my Like, What Does It Mean?)
'Consciousness' taken narrowly refers to phenomenal consciousness, pleasures, pains, emotions, and the like, but taken widely it embraces also thought, reasoning and evaluation. Sensory qualia are present in nonhuman animals, but only we think, reason, and evaluate. We evaluate our thoughts as either true or false, our reasonings as either valid or invalid, and our actions as either right or wrong, good or bad. These higher-level capacities can be possessed only by beings that are also conscious in the narrow sense. Thus no computer literally thinks or reasons or evaluates the quality of its reasoning imposing norms on itself as to how it ought to reason if it is to arrive at truth; at best computers simulate these activities. Talk of computers thinking is metaphorical. This is a contested point, of course. But if mind is a biological phenomenon as Nagel maintains, then this is not particularly surprising.
What makes consciousness fascinating is that while it is irreducibly subjective, it is also, in its higher manifestations, transcensive of subjectivity. (This is my formulation, not Nagel's.) Mind is not trapped within its interiority but transcends it toward impersonal objectivity, the "view from nowhere." Consciousness develops into "an instrument of transcendence that can grasp objective reality and objective value." (85) Both sides of mind, the subjective and the objective, pose a problem for reductive naturalism. "It is not merely the subjectivity of thought but its capacity to transcend subjectivity and to dsiscover what is objectively the case that presents a problem." (72)
Exactly right! One cannot prise apart the two sides of mind, segregating the qualia problem from the intentionality problem, calling the former 'hard' and imagining the latter to be solved by some functionalist analysis. It just won't work. The so-called Hard Problem is actually insoluble on reductive naturalism, and so is the intentionality problem. (Some who appreciate this go eliminativist — which is a bit like getting rid of a headache by blowing one's brains out.)
The main problem Nagel deals with in this chapter concerns the reliability of reason. Now it is a given that reason is reliable, though not infallible, and that it is a source of objective knowledge. The problem is not whether reason is reliable as a source of knowledge, but how it it is possible for reason to be reliable if evolutionary naturalism is true. I think it is helpful to divide this question into two:
Q1. How can reason be reliable if materialist evolutionary naturalism is true?
Q2. How can reason be reliable if evolutionary naturalism is true?
Let us not forget that Nagel himself is an evolutionary naturalist. He is clearly a naturalist as I explained in my first post, and he does not deny the central tenets of the theory of evolution. His objections are to reductive materialism (psychophysical reductionism) and not to either naturalism or evolution. Now Nagel is quite convinced, and I am too, that the answer to (Q1) is that it is not possible for reason to be relied upon in the manner in which we do in fact rely upon it, if materialism is true. The open question for Nagel is (Q2). Reason is reliable, and some version of evolutionary naturalism is also true. The problem is to understand how it is possible for both of them to be true.
Now in this post I am not concerned with Nagel's tentative and admttedly speculative answer to (Q2). I hope to take that up in a subsequent post. My task at present is to understand why Nagel thinks that it is not possible for reason to be reliable if materialism is true.
Suppose we contrast seeing a tree with grasping a truth by reason.
Vision is for the most part reliable: I am, for the most part, justified in believing the evidence of my senses. And this despite the fact that from time to time I fall victim to perceptual illusions. My justification is in no way undermined if I think of myself and my visual system as a product of Darwinian natural selection. "I am nevertheless justified in believing the evidence of my senses for the most part, because this is consistent with the hypothesis that an accurate representation of the world around me results from senses shaped by evolution to serve that function." (80)
Now suppose I grasp a truth by reason. (E.g., that I must be driving North because the rising sun is on my right.) Can the correctness of this logical inference be confirmed by the reflection that the reliability of logical thinking is consistent with the hypothesis that evolution has selected instances of such thinking for accuracy?
No, says Nagel and for a very powerful reason. When I reason I engage in such operations as the following: I make judgments about consistency and inconsistency; draw conclusions from premises; subsume particulars under universals, etc. So if I judge that the reliability of reason is consistent with an evolutionary explanation of its origin, I presuppose the reliability of reason in making this very judgement. Nagel writes:
It is not possible to think, "reliance on my reason, including my reliance on this very judgment, is reasonable because it is consistent with its having an evolutionary explanation." Therefore any evolutionary account of the place of reason presupposes reason's validity and cannot confirm it without circularity. (80-81)
Nagel's point is that the validity of reason can neither be confirmed nor undermined by any evolutionary account of its origins. Moreover, if reason has a merely materialist origin it would not be reliable, for then its appearance would be a fluke or accident. And yet reason is tied to organisms just as consciousness is. Nagel faces the problem of explaining how reason can be what it is, an "instrument of transcendence" (85) and a "final court of appeal" (83), while also being wholly natural and a product of evolution. I'll address this topic in a later post.
Why can't reason be a cosmic accident, a fluke? This is discussed in my second post linked to above, though I suspect I will be coming back to it.
True human height is not measured in feet and inches but in the altitude of the thoughts we think and the problems we engage. The higher the problems, the higher the man.
Speaking Neatly. Excerpt:
FALSE APHORISMS are not as rare as one might think. More significant than Wilde's, on account of its influence, is Marx's dismissal of religion as "the opium of the people." For this implies that religion is adopted purely for its ability to soothe the wounds of society, and that there is some other condition to which humanity might advance in which religion would no longer be needed. Both those implications are false, but they are boiled into a stock cube as tasty as any that has been seen on the intellectual menu. How many would-be intellectuals have dissolved this cube into their prose and given their thought, in the manner of Christopher Hitchens, a specious air of wisdom?
Permit me a quibble. Should we call a striking formulation lifted from a wider context an aphorism? I don't think so. An aphorism by my lights is a pithy observation intended by its author to stand alone. Accordingly, Marx's famous remark is not an aphorism. The wider context is provided here.
In lieu of oldies this Saturday night, a taste of Bob Dylan's latest, Tempest. Duquesne Whistle. Sampler. 1962 version of "Roll on, John" 50 years of assimilation and creative reworking of musical Americana by the unlikely Jewish kid from Hibbing, Minnesota.
Jody Rosen's New Yorker review. Insightful:
The hunt for Dylan in Dylan songs is a mug’s game. Dylan is a genius; he’s also the greatest bullshitter and jive-talker in popular-music history. He began laying boobytraps for his exegetes before he even had any, and they—we—have never stopped taking the bait. Today Dylanology is a midrashic enterprise rivaling Talmudism and Shakespeare Studies, and it’s worth remembering its origins: it started with the hippie gadfly A .J. Weberman, who took to “reading” toothbrushes recovered from garbage bins outside of Dylan’s MacDougal Street townhouse.

The original Dylanological sin is to focus too much on the words, and too little on the sound: to treat Dylan like he’s a poet, a writer of verse, when of course he’s a musician—a songwriter and, supremely, a singer. “Tempest” reminds us what a thrilling and eccentric vocalist he is.
