However often experiment and reasoning may show a man that under the same conditions and with the same character he will do the same thing as before, yet when under the same conditions and with the same character he approaches for the thousandth time the action that always ends in the same way, he feels as certainly convinced as before the experiment that he can act as he pleases. Every man, savage or sage, however incontestably reason and experiment may prove to him that it is impossible to imagine two different courses of action in precisely the same conditions, feels that without this irrational conception (which constitutes the essence of freedom) he cannot imagine life. He feels that however impossible it may be, it is so, for without this conception of freedom not only would he be unable to understand life, but he would be unable to live for a single moment.
He could not live, because all man’s efforts, all his impulses to life, are only efforts to increase freedom. Wealth and poverty, fame and obscurity, power and subordination, strength and weakness, health and disease, culture and ignorance, work and leisure, repletion and hunger, virtue and vice, are only greater or lesser degrees of freedom.
