But neither life nor happiness can be achieved by the pursuit of irrational whims. Just as man is free to attempt to survive in any random manner, but will perish unless he lives as his nature requires, so he is free to seek his happiness in any mindless fraud, but the torture of frustration is all he will find, unless he seeks the happiness proper to man. The purpose of morality is to teach you, not to suffer and die, but to enjoy yourself and live.

Life is a value to be bought and thinking is the only coin noble enough to buy it.

Professional intellectuals are the voice of a culture and are, therefore, its leaders, its integrators and its bodyguards.

Do not let the hero in your soul perish in lonely frustration for the life you deserved and have never been able to reach.

In western civilization, the period ruled by mysticism is known as the 'Dark Ages' and the 'Middle Ages'. I will assume that you know the nature of that period and the state of human existence in those ages. The Renaissance broke the rules of the mystics. "Renaissance" means the "rebirth". Few people today will care to remind you that it was a rebirth of reason - of man's mind.

Don't help me or serve me, but let me see it once, because I need it. Don't work for my happiness, my brothers — show me yours — show me that it is possible — show me your achievement — and the knowledge will give me courage for mine.

When intellectual leaders fail to foster the best in the mixed, unformed, vacillating character of people at large, the thugs are sure to bring out the worst. When the ablest men turn into cowards, the average men turn into brutes.
