The Twilight Zone

Most of the “pop culture and philosophy” books that have flooded the Borders and Barnes and Noble shelves in recent years seem to me to be pretty schlocky. Their purported justification is that they introduce philosophy to people who wouldn’t otherwise read it. But since the “philosophical significance” of the subject matter is usually vastly overstated (30 Rock? Jimmy Buffett? The Atkins Diet?!) and the philosophy dumbed down, it is questionable whether they really do much good on this score.

Still, there are pop culture topics that are worthy of philosophical consideration. As our pal Bill Vallicella has noted, The Twilight Zone is one of them. Naturally, a volume on that subject has appeared, and while I have not yet read Philosophy in the Twilight Zone, it looks interesting and I plan to do so. In any event, anyone who has watched the show can think of examples of episodes which raise serious philosophical questions.

In “The Man in the Bottle,” a genie grants a down-on-their-luck couple four wishes. This turns out, of course, to be less of a blessing than they assume it will be. Watching this episode as a youngster spawned one of the first philosophical thoughts I can recall ever having: Why couldn’t the couple wish for ten or twenty more wishes, as the husband suggests doing at one point? The genie just says that “wishing for more wishes is not permitted,” but this limitation seems arbitrary. It also seems easy to get around, for why couldn’t the husband just respond: “OK, then in that case I wish you hadn’t imposed that arbitrary rule!” And if the genie then said that that was also something that couldn’t be wished for, why couldn’t the husband reply that his wish in that case is that that rule had never been imposed?

The indeterminacy illustrated by this example – the difficulty of “nailing down” the content of a certain rule or statement so that what one wants it to rule out really is ruled out – is in fact part of the larger theme of the episode. Every wish the couple makes – for money, for power – turns out to have unforeseen unhappy implications, and there seems to be no way to add detail to the description of the content of the wish to make absolutely certain that no further iteration of the same basic problems can crop up. Readers of Wittgenstein, Hayek, or Kripke will appreciate the difficulty. There is also moral and political significance to the problem the episode raises. We are often prone to think of personal and social problems in terms of what would happen if only we could “press a button.” In fact this is a very foolish way to think, because human life and human problems are typically far too complicated to boil down to a single factor, the alteration of which would solve everything.

In “A Most Unusual Camera,” a gang of petty criminals acquires a camera that takes pictures of events that have not yet occurred. It turns out that the knowledge of future events that they acquire by means of the camera is one of the factors that lead to the realization of said events. Obvious fodder for those interested in time travel paradoxes and questions about determinism and free will. In “It’s a Good Life,” omnipotent 6-year old Anthony Fremont terrorizes a small town. He is clearly selfish, callous, and willful, and causes unimaginable suffering to those around him. But he is only 6, and arguably lacking in understanding both of the moral law and of the consequences of his actions. So, does he have sufficient moral responsibility for it to be morally permissible to kill him so as to save the town from the horrors he inflicts upon it? Discuss. In “A Kind of a Stopwatch,” a man acquires a watch that can stop time. I’ve used it in the classroom for years to illustrate the question that initiates the Aristotelian argument from motion: Why is the world dynamic rather than static? Why does it undergo change rather than being “frozen in place,” as the episode’s characters are when the stopwatch is pressed?

You get the idea. Of course, The Twilight Zone has other, non-philosophical charms. Perhaps there is some deep epistemological issue raised by the famous “Nightmare at 20,000 Feet”; but the reason it is so many people’s favorite episode is simply that it gives a good scare. (It made it at least a little harder for my 5-year old daughter to get on the plane to London with her mother last week!)

And then there is the excuse it gives me to link to a classic Manhattan Transfer video. Enjoy:

Popper’s World 3

The Self and Its Brain: An Argument for Interactionism, a long exchange between philosopher Karl Popper and neuroscientist John Eccles, is among the most significant 20th century defenses of mind-body dualism. I do not agree with every aspect of their approach, but the book is filled with interesting things and deserves more attention than it has received in contemporary philosophy of mind.

Popper famously distinguished between three “worlds” or levels of reality. (Though whether “levels” of reality is the right gloss on Popper’s theory is not clear. “Kinds”? “Aspects”?) World 1 is the world of physical entities and states – tables, chairs, rocks, trees, fundamental particles and forces, human bodies and behavior, and so forth. World 2 is the world of thoughts, sensations, and mental phenomena in general. World 3 is the world of scientific and philosophical theories, arguments, stories, social institutions, works of art and the like. World 3 differs from World 1 in that the entities comprising it are abstract; for example, though a theory or argument might be embodied in a particular book (a World 1 object) it does not depend for its reality on the existence of that book, or on any book or World 1 object at all. We could still consider the Pythagorean theorem, know it to be true, prove it, etc. even if every geometry textbook that had ever existed were destroyed. World 3 differs from World 2 in being objective or public, whereas World 2 is subjective or private. Your thoughts and experiences are directly knowable only to you, but World 3 objects are equally accessible to everyone.

The objectivity or “autonomy” of such World 3 objects as theories and arguments is especially evident in Popper’s view from the fact that they have logical relations – and in particular, unforeseen implications and unnoticed inconsistencies – that may not be noticed until well after we first consider them, but which were evidently there all the time waiting to be discovered. Naturally, he takes mathematics to illustrate the point vividly, but it is in his view no less evident from empirical scientific theories. The clearest mark of the reality of all three worlds is in Popper’s judgment the fact that World 3 has a causal influence on World 1, and does so only via World 2. For example, the scientific theories which entailed the possibility of nuclear weapons have had an obvious impact on the material world – they have resulted in various nuclear tests, in the destruction of Hiroshima and Nagasaki, and so forth – but only because scientists carried out the mental activity of working out the implications of the theories and applying them.

Popper’s World 3 is often compared to Plato’s realm of the Forms, and Popper himself acknowledges that there are similarities. But he also emphasizes the significant differences between his view and Plato’s, not the least of which is that he takes World 3, despite its objectivity or autonomy, to be something “man-made,” its objects in the strict sense being what the human mind “abstracts” from their World 1 embodiment. Though Popper does not take note of the fact or develop the theme in much detail, this is clearly reminiscent of an Aristotelian or “moderate realist” approach to the traditional problem of universals, as distinct from the “extreme realism” of Platonism. (See here and here for a useful short account of the traditional Aristotelian-Thomistic-Scholastic approach to the issue and its significance.)

In other ways too Popper’s views as expressed in The Self and Its Brain overlap to some extent with Aristotelian ones. The emphasis on abstract thought – and thus on what is unique to human beings – as what is of greatest interest in the debate over dualism is very much in line with the classical Platonic-Aristotelian-Scholastic approach to this subject, which is quite different from the contemporary obsession with “qualia” and the like. There is also Popper’s acknowledgement of the reality of “downward causation” in physical systems and his consequent rejection of physicalistic reductionism even where non-mental phenomena are concerned. And there is his affirmation of the existence of objective “propensities” in nature, which (possibly) hints at something like the Aristotelian notion of potencies. (Though these last two themes take us beyond the World 3 thesis itself.)

On the other hand, there are some decidedly un-Aristotelian themes in Popper as well. There is, for instance, his denial of substance in favor of a “process” conception of the material world; and there is his rejection of essentialism, which he seems to assume is inherently Platonistic and committed to an a priori or “armchair” methodology. (This is a serious misunderstanding, and a very common one, which we Aristotelian-Thomistic (A-T) types find it rather tiresome constantly to have to rebut. See Oderberg’s Real Essentialism for the most thorough rebuttal, and pp. 30-38 for a reply to Popper specifically.)

All the same, any Aristotelian must admire the non-ideological character of Popper’s approach to the mind-body problem. Unlike so many contemporary philosophers of mind, he does not fatuously pretend that a presumption in favor of materialism has somehow been established by modern science, or that dualism rests on “intuitions” or the like. He does not present the problem situation as if it were a matter of determining whether we ought to wedge the evidence of our ordinary experience into the Procrustean bed of naturalism or instead to lop it off entirely – as if these were the only alternatives worth taking seriously. Nor does he have any theological ax to grind; he deliberately avoids getting into the question of the soul’s immortality (and even expresses the view that he would prefer not to be immortal). He merely observes that reality clearly comprises at least the three sorts of thing in question and that any serious solution to the mind-body problem will simply have to accommodate this plain fact. As The Self and Its Brain shows, Popper is also much better informed about the actual history of the mind-body problem than contemporary naturalists tend to be. (As my series of posts on Paul Churchland indicated, many naturalists seem unfamiliar with anything other than the crudest caricatures of what non-naturalist philosophers of mind have actually said.)

In short, at least where the mind-body problem is concerned, Popper does not attack straw men and he respects Butler’s famous dictum that “Everything is what it is, and not another thing.” (I put to one side for present purposes Popper’s views in political philosophy and philosophy of science, contexts in which he is more open to criticism on these grounds.) He thereby stands acquitted of a charge John Searle raised in The Rediscovery of the Mind against his fellow contemporary philosophers of mind:

[W]e let our research methods dictate the subject matter, rather than the converse. Like the drunk who loses his car keys in the dark bushes but looks for them under the streetlight, "because the light is better here,” we try to find out how humans might resemble our computational models rather than trying to figure out how the conscious human mind actually works…

[W]e ought to stop saying things that are obviously false. The serious acceptance of this maxim might revolutionize the study of the mind. (p. 247)

Like Searle, Popper is in my estimation better as a critic than as a positive theorist. (I discussed an important anti-materialist argument of his in an earlier post.) Still, from an A-T point of view even his positive theorizing is closer to the mark than that of most other contemporary dualists.

Blogging note

In case anyone is wondering, the recent paucity of blog posts (or at least of substantial ones) owes to the fact that I have been on jury duty for nearly two weeks. On top of that, my wife is away for a week with two of the kids while I am watching the other three (or rather, scrambling to get others to watch them while I am at the courthouse). So, little time for blogging, much less getting any work done. Things should be back to normal by next week.
