Philosophers are not honest enough in their work, although they make a lot of virtuous noise when the problem of truthfulness is touched even remotely. They all pose as if they had discovered and reached their real opinions through the self-development of a cold, pure, divinely unconcerned dialectic...; while at bottom it is an assumption, a hunch, indeed a kind of "inspiration" most often a desire of the heart that has been filtered and made abstract that they defend with reasons they have sought after the fact.
One who is unassuming in dealing with people exhibits his arrogance all the more strongly in dealing with things (city, state, society, age, mankind). That is his revenge.
Whoever deliberately attempts to insure confidentiality with another person is usually in doubt as to whether he inspires that person's confidence in him. One who is sure that he inspires confidence attaches little importance to confidentiality.
People are always angry at anyone who chooses very individual standards for his life; because of the extraordinary treatment which that man grants to himself, they feel degraded, like ordinary beings.
All philosophers make the common mistake of taking contemporary man as their starting point and of trying, through an analysis of him, to[21] reach a conclusion. "Man" involuntarily presents himself to them as an aeterna veritas as a passive element in every hurly-burly, as a fixed standard of things. Yet everything uttered by the philosopher on the subject of man is, in the last resort, nothing more than a piece of testimony concerning man during a very limited period of time.
Logic, too, also rests on assumptions that do not correspond to anything in the real world, e.g., on the assumption that there areequal things, that the same thing is identical at different points in time: but this science arose as a result of the opposite belief (that such things actually exist in the real world). And it is the same with mathematics, which would certainly never have arisen if it had been understood from the beginning that there is no such thing in nature as a perfectly straight line, a true circle, and absolute measure.
