Ignorance is the primary source of all misery and vice.

If ignorance is bliss, there should be more happy people.

A person should refrain from all those things that take him towards fallacy, misery, ignorance and degradation.

True philosophy invents nothing; it merely establishes and describes what is.

All men have an equal right to the free development of their faculties; they have an equal right to the impartial protection of the state; but it is not true, it is against all the laws of reason and equity, it is against the eternal nature of things, that the indolent man and the laborious man, the spendthrift and the economist, the imprudent and the wise, should obtain and enjoy an equal amount of goods.

You can only govern men by serving them. The rule is without exception.
