The purpose of man's life...is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question.

Live and act within the limit of your knowledge and keep expanding it to the limit of your life. Redeem your mind from the hockshops of authority. Accept the fact that you are not omniscient, but playing a zombie will not give you omniscience-that your mind is fallible, but becoming mindless will not make you infallible-that an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error.

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.

If you want to feel good, be rational.

The right of a nation to determine its own form of government does not include the right to establish a slave society (that is, to legalize the enslavement of some men by others). There is no such thing as "the right to enslave." A nation can do it, just as a man can become a criminal- but neither can do it by right.

The alleged short-cut to knowledge, which is faith, is only a short-circuit destroying the mind

Litigants obey the verdict of a tribunal solely on the premise that there is an objective rule of conduct, which they both accept.
