Metaphysics means nothing but an unusually obstinate effort to think clearly. The fundamental conceptions of psychology are practically very clear to us, but theoretically they are very confused, and one easily makes the obscurest assumptions in this science without realizing, until challenged, what internal difficulties they involve.William James

There is something almost shocking in the notion of so chaste a function carrying this Kantian hurlyburly in her womb.William James

But it is the bane of psychology to suppose that where results are similar, processes must be the same. Psychologists are too apt to reason as geometers would, if the latter were to say that the diameter of a circle is the same thing as its semi-circumference, because, forsooth, they terminate in the same two points.William James

A man's Self is the sum total of all that he can call his, not only his body and his psychic powers, but his clothes and his house.William James
