Chapter Vi, Sections 23-25. See Chapters X and Xi, "system of

Metaphysics," "The Kantian Doctrine of Space" and "Difficulties connected with the Kantian Doctrine of Space."

It would be an excellent thing for the student, after he has read the above chapters, to take up Kant's "Critique of Pure Reason," and read and analyze the argument of Antinomies I and II, with the Observations appended. One can understand these arguments without being familiar with the "Critique" as a whole; at any rate, the account of Kant's philosophy contained in section 51 of this book will serve to explain his use of certain terms, such as "the laws of our sensibility."

Kant's reasonings are very curious and interesting in this part of his book. It seems to be proved that the world must be endless in space and without a beginning or end in time, and just as plausibly proved that it cannot be either. It seems to be proved that finite spaces and times are infinitely divisible, and at the same time that they cannot be infinitely divisible. The situation is an amusing one, and rendered not the less amusing by the seriousness with which the mutually destructive arguments are taken.

When the student meets such a tangle in the writings of any philosopher, I ask him to believe that it is not the human reason that is at fault--at least, let him not assume that it is. The fault probably lies with a human reason.
