The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.
Men best show their character in trifles, where they are not on their guard. It is in the simplest habits, that we often see the boundless egotism which pays no regard to the feelings of others and denies nothing to itself.
Indeed, intolerance is essential only to monotheism; an only God is by nature a jealous God who will not allow another to live. On the other hand, polytheistic gods are naturally tolerant, they live and let live.
Scholars are those who have read in books, but thinkers, men of genius, world-enlighteners, and reformers of the human race are those who have read directly in the book of the world.
The man who sees two or three generations is like one who sits in the conjuror's booth at a fair, and sees the same tricks two or three times. They are meant to be seen only once.

A man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.
Boredom is an evil that is not to be estimated lightly. It can come in the end to real despair. The public authority takes precautions against it everywhere, as against other universal calamities.
Shame on such a morality that is worthy of pariahs, and that fails to recognize the eternal essence that exists in every living thing, and shines forth with inscrutable significance from all eyes that see the sun!
What a man can do and suffer is unknown to himself till some occasion presents itself which draws out the hidden power. Just as one sees not in the water of an unruffled pond the fury and roar with which it can dash down a steep rock without injury to itself, or how high it is capable of rising; or as little as one can suspect the latent heat in ice-cold water.
