hysics," "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.

Section 26. See Chapter XII, "The Berkeleian Doctrine of Space," in my
"System of Metaphysics." The argument ought not to be difficult to one
who has mastered Chapter V of this volume.

CHAPTER VII, sections 27-29. Compare Chapter XIII, "System of
Metaphysics," "Of Time."

With the chapters on Space and Time it would be well for the student to
read Chapter XIV, "The Real World in Space and Time," where it is made
clear why we have no hesitation in declaring space and time to be
infinite, although we recognize that it seems to be an assumption of
knowledge to declare the material world infinite.

CHAPTER VIII, sections 30-32. Read, in the "System of Metaphysics,"
Chapters V and XVII, "The Self or Knower" and "The Atomic Self."

Section 33. The suggestions, touching the attitude of the psychologist
toward the mind, contained in the preface to Professor William James's
"Psychology" are very interesting and instructive.

CHAPTER IX, sections 35-36. For a strong argument in favor of
interactionism see James's "Psychology," Chapter V. I wish the student
would, in reading it, bear in min
