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.

In all living nature (and perhaps also in that which we consider as dead) love is the motive force which drives the creative activity in the most diverse directions.

Think about death. You do not know how much time remains to you. And remember that if you do not become different, everything will be repeated again, all foolish blunders, all silly mistakes, all loss of time and opportunity - everything will be repeated with the exception of the chance you had this time, because chance never comes in the same form.You will have to look for your chance next time. And in order to do this, you will have to remember many things, and how will you remember then if you do not remember anything now?

Philosophy is based on speculation, on logic, on thought, on the synthesis of what we know and on the analysis of what we do not know. Philosophy must include within its confines the whole content of science, religion and art.

People live in sleep, do everything in sleep, and do not know they are asleep.

If a man gives way to all his desires, or panders to them, there will be no inner struggle in him, no 'friction,' no fire. But if, for the sake of attaining a definite aim, he struggles with desires that hinder him, he will then create a fire which will gradually transform his inner world into a single whole.

We often think we express negative emotions, not because we cannot help it, but because we should express them.
