A man’s real nature is never altered by education.

There are men who are willing to marry a woman they do not care about merely because she is admired by other men. Such a relation exists between many men and their thoughts.

If it really were the case, as popular opinion has tried to establish, that the genius were separated from ordinary men by a thick wall through which no sound could penetrate, then all understanding of the efforts of genius would be denied to ordinary men, and their works would fail to make any impression on them. All hopes of progress depend on this being untrue. And it is untrue. The difference between men of genius and the others is quantitative not qualitative, of degree not of kind.

Among the notable things about fire is that it also requires oxygen to burn – exactly like its enemy, life. Thereby are life and flames so often compared.

An individual’s arrogance is always in proportion to his lack of self-assurance.

The danger of insanity is always present in those who try to penetrate the discipline of logic and pure knowledge.

Logic and ethics are fundamentally the same, they are no more than duty to oneself.

Sending children away to get control of their anger perpetuates the feeling of 'badness" inside them...Chances are they were already feeling not very good about themselves before the outburst and the isolation just serves to confirm in their own minds that they were right.

Mankind occurs as male or female, as something or nothing. Woman has no share in ontological reality, no relation to the thing-in-itself, which, in the deepest interpretation, is the absolute, is God. Man in his highest form, the genius, has such a relation, and for him the absolute is either the conception of the highest worth of existence, in which case he is a philosopher; or it is the wonderful fairyland of dreams, the kingdom of absolute beauty, and then he is an artist.

The man of genius is he whose ego has acquired consciousness. He is enabled by it to distinguish the fact that others are different, to perceive the "ego" of other men, even when it is not pronounced enough for them to be conscious of it themselves. But it is only he who feels that every other man is also an ego, a monad, an individual centre of the universe, with specific manner of feeling and thinking and a distinct past, he alone is in a position to avoid making use of his neighbours as means to an end.
