To a wise and good man the whole earth is his fatherland.
Good means not [merely] not to do wrong, but rather not to desire to do wrong.
Soul and intellect are just the same things.
We think there is color, we think there is sweet, we think there is bitter, but in reality there are atoms and a void.
Nature and education are somewhat similar. The latter transforms man, and in so doing creates a second nature.
The first principles of the universe are atoms and empty space; everything else is merely thought to exist.
