Truths that become old become decrepit and unreliable; sometimes they may be kept going artificially for a certain time, but there is no life in them.

There is no tyranny more ferocious than the tyranny of morality. Everything is sacrificed to it.

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.

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.

Our ancestors were very rich and eminent people, and they left us an enormous inheritance, which we have completely forgotten, especially since the time when we began to consider ourselves the descendants of a monkey.

You can understand other people only as much as you understand yourself and only on the level of your own being. This means you can judge other people's knowledge but you cannot judge their being. You can see in them only as much as you have in yourself. But people always make the mistake of thinking they can judge other people's being. In reality, if they wish to meet and understand people of a higher development than themselves they must work with the aim of changing their being.

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.
