Consider the Koran... this wretched book was sufficient to start a world-religion, to satisfy the metaphysical need of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. In this book we find the saddest and poorest form of theism. Much may be lost in translation, but I have not been able to discover in it one single idea of value.
Faith is like love, it cannot be forced. Therefore it is a dangerous operation if an attempt be made to introduce or bind it by state regulations; for, as the attempt to force love begets hatred, so also to compel religious belief produces rank unbelief.
There are three stages in the revelation of truth. The first is to be ridiculed, the second is to be resisted and the third is to be considered self-evident.
There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. ... The truth is that when an author begins to write for the sake of covering paper, he is cheating the reader; because he writes under the pretext that he has something to say.
If at times I have thought myself unfortunate, it is because of a confusion, an error. I have mistaken myself for someone else... Who am I really? I am the author of The World as Will and Representation, I am the one who has given an answer to the mystery of Being that will occupy the thinkers of future centuries. That is what I am, and who can dispute it in the years of life that still remain for me?
Style is the physiognomy of the mind. It is more infallible than that of the body. To imitate the style of another is said to be wearing a mask. However beautiful it may be, it is through its lifelessness insipid and intolerable, so that even the most ugly living face is more engaging.
He who lives to see two or three generations is like a man who sits some time in the conjurer's booth at a fair, and witnesses the performance twice or thrice in succession. The tricks were meant to be seen only once; and when they are no longer a novelty and cease to deceive, their effect is gone.
It is the courage to make a clean breast of it in the face of every question that makes the philosopher. He must be like Sophocles' Oedipus, who, seeking enlightenment concerning his terrible fate, pursues his indefatigable inquiry even though he divines that appalling horror awaits him in the answer. But most of us carry with us the Jocasta in our hearts, who begs Oedipus, for God's sake, not to inquire further.
Were an Asiatic to ask me for a definition of Europe, I should be forced to answer him: It is that part of the world which is haunted by the incredible delusion that man was created out of nothing, and that his present birth is his first entrance into life.
How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.
For an author to write as he speaks is just as reprehensible as the opposite fault, to speak as he writes; for this gives a pedantic effect to what he says, and at the same time makes him hardly intelligible.
