“Regarding man as a subject of observation from whatever point of view—theological, historical, ethical, or philosophic—we find a general law of necessity to which he (like all that exists) is subject. But regarding him from within ourselves as what we are conscious of, we feel ourselves to be free. This consciousness is a source of self-cognition quite apart from and independent of reason. Through his reason man observes himself, but only through consciousness does he know himself. Apart from consciousness of self no observation or application of reason is conceivable. To understand, observe, and draw conclusions, man must first of all be conscious of himself as living. A man is only conscious of himself as a living being by the fact that he wills, that is, is conscious of his volition. But his will—which forms the essence of his life—man recognizes (and can but recognize) as free. If, observing himself, man sees that his will is always directed by one and the same law (whether he observes the necessity of taking food, using his brain, or anything else) he cannot recognize this never-varying direction of his will otherwise than as a limitation of it. Were it not free it could not be limited. A man’s will seems to him to be limited just because he is not conscious of it except as free.” – Leo Tolstoy, War and Peace (trans. Louise and Aylmer Maude)
