I have become so accustomed to think "scientifically" that I am afraid even to imagine that there may be something else beyond the outer covering of life. I feel like a man condemned to death, whose companions have been hanged and who has already become reconciled to the thought that the same fate awaits him.

Man has no permanent and unchangeable I. Every thought, every mood, every desire, every sensation says "I." And in each case it seems to be taken for granted that this I belongs to the Whole, to the whole man, and that a thought, a desire, or an aversion is expressed by this Whole.

Man is a machine which reacts blindly to external forces and, this being so, he has no will, and very little control of himself, if any at all. What we have to study, therefore, is not psychology-for that applies only to a developed man-but mechanics. Man is not only a machine but a machine which works very much below the standard it would be capable of maintaining if it were working properly.
