When you are cooped up in an apartment, as I have been for
more than seven months, you quite naturally cast about for sources of
amusement. This quest has led me to some pretty bad movies on Netflix, to some
interesting brief lectures about Paleolithic man on YouTube, and also to a
number of the interviews and lectures that have been posted there featuring
Noam Chomsky. It is difficult actually to know when the original interview or
lecture took place because the date given is simply the date on which it was
uploaded, but by watching Noam age and his hair grow somewhat longer, it is
possible to take a guess as to whether what I am watching is five years old or
40 years old. After a while, I noticed that he repeats himself, sometimes using
the very same linguistic examples. How could it be otherwise? Even for someone
like Noam who has virtually transformed an entire field by his work and has
ranged across the world in his political commentary, there have to be times
when he seeks to say the same things in slightly different ways.
In a much diminished fashion, I face a similar problem.
After publishing 21 books, writing eight or 10 others that have not been
formally published, and posting well over a million words on this blog, I find
myself saying things that at some time, somewhere, in some form or other, I
have said before. Last night as I lay awake at about 3 AM, I began to think
about the deep contradiction that exists between Kant’s theory of knowledge and
his ethical theory, a fact that I think is essential to an understanding of his
work. I have actually published an article on this subject, but it appeared in
a book so obscure that I am not sure anybody still alive has ever read it.
Curious as to whether I had talked about this on my blog, I used the search
facility it provides and sure enough found that at the end of the 19 part
series on Kant’s Critique of Pure Reason posted in August 2011, I had indeed
discussed this subject in a relatively brief form.
Now, nine years is several lifetimes in cyberspace and there
cannot be many current readers of this blog who were actually around when I
posted that series and furthermore who read it, so it occurred to me that as we
all await the results of the election, this might be a good time to step aside
from that tension producing enterprise and once again explain why I believe
that there is an insoluble conflict between Kant’s theoretical philosophy and
his moral philosophy. I have no idea whether anyone reading this blog these
days will find the subject of any interest whatsoever but I surely do and it is
my blog so here goes. We shall see how long I can keep myself diverted from an
obsessive examination of the latest poll results.
Let me begin with what theoretical physicists call a gedankenexperiment. Let us suppose that a professor of creative
writing is teaching a class of 12 students to whom she gives the following
exercise: write a short story about this class, being sure that your story
satisfies two requirements, first, that every member of the class appear by
name in the story and second, that the story be in the form of a first person
narration with the narrator being the character in the story who represents
you, the author. In general, we may assume, the twelve students will write twelve
quite different stories but it is imaginable that by some fluke (or, as Leibniz
would say, by a preestablished harmony), all twelve stories will be word for word
identical (I assume that the author refers to himself or herself by name rather
than by the word “I”.)
Even in this unlikely event, the stories will differ each
from the other in one fundamental respect. In each story, the character who
represents the author will be different. In Lydia’s story, the character named
Lydia will be the appearance in the story of the author, who is Lydia. In
Nathan’s story, the character in the story who is the appearance of the author
will be Nathan, and so forth. Leaving aside cheating or joint authorship, is
there any way that two characters in numerically the same story could each be
the appearance in the story of its author? The answer is self-evidently no.
But in order for Kant’s ethical theory to be logically
compatible with his theory of knowledge, the answer to this question would have
to be yes. How so? I will explain.
As I trust we are all aware, Kant believes that the Moral
Law is binding on and applies to persons, which is to say to things in
themselves, or more precisely to selves in themselves, not to phenomenal
appearances. As an appearance in the realm of phenomena, I like every other
appearance stand under universal causal laws. Just as one can with sufficient
knowledge predict the movement of billiard balls or stars or leaves falling
from a tree, so with sufficient knowledge one can predict the behavior (not,
notice, the actions) of human beings.
The Moral Law is the universal principle, knowable a priori,
that binds absolutely all rational agents as such, whether human or otherwise.
The law is experienced by we who are humans and who are only imperfectly
rational, as a categorical imperative or command but if there are perfectly
rational agents, such as angels, they would experience the Moral Law in much
the way that logicians experience the laws governing the syllogism. I may be
tempted to break a promise, hoping that I can get away with it, but no logician
is tempted, when no one is looking, to decide that if some A are B, and some B
are C, then some A are C.
What is more, my duties are to other persons as rational
agents, not to their appearances in the realm of phenomena. It is this fact,
understood if not articulated, that gives rise to the familiar trope in science
fiction of the explorer on a foreign planet who wonders which of the objects
she encounters are the local inhabitants and which are merely part of the fauna
and flora. Is Jar-Jar Binks a rational
agent to whom I owe debts of truth and equity or just an odd looking plant? It may take a while to figure out that
Chewbacca is indeed a person worthy of respect. (I pass over in silence Kant’s
views on duties to oneself, such as the duty to develop one’s talents and not
to abuse oneself. I can understand why some parents may think that a dutiful
son should practice the violin and not masturbate but I do not think that rises
to the level of universal ethical theory.)
And now the problem should be clear. According to Kant (or
at least the interpretation of his philosophy to which I committed myself more
than 60 years ago and from which I have never deviated), the transcendental ego
synthesizes the manifold of intuition in such a manner as to impose upon it
necessitated regularities that constitute the laws of nature. As Kant says in a
famous passage in the first edition Deduction, “the understanding… is itself
the lawgiver of nature.… However exaggerated and absurd it may sound to say
that the understanding is itself the source of the laws of nature, and so of its
formal unity, such an assertion is nonetheless correct and is in keeping with
the object to which it refers, namely experience.” (A126-7)
On reflection, it should be immediately obvious that just as
it cannot be the case that two students in the class are each of them the
author of numerically the same short story, even if each writes a story that is
word for word identical with that written by the other, so it cannot be the
case that two different noumenal agents, through their synthesizing activities
in their role as transcendental egos, bring into existence numerically the same
field of experience. Which means that no morally responsible agent, no person,
can ever encounter in his or her or its field of experience the phenomenal
appearance of another moral agent.
One could of course try to save Kant’s moral theory by
arguing that it is not false but merely vacuous. The moral law would bind me if
I could ever encounter someone to whom I could make promises or to whom I could
tell the truth or with whom collectively I could enact the laws of the realm of
ends, but by an obstacle impossible to overcome, I can never in principle be in
a position to put the Moral Law into action.
I am quite certain that Kant himself was never aware of this
problem and it is my impression, unsupported by an adequate reading of the
secondary literature, that the problem is not widely recognized even today by
Kant scholars.
Well, enough of that. Back to dissecting the polls.
