Everywhere man blames nature and fate yet his fate is mostly but the echo of his character and passion, his mistakes and his weaknesses.

By convention hot, by convention cold, by convention color, but in reality atoms and void.

Do not trust all men, but trust men of worth; the former course is silly, the latter a mark of prudence.

[Democritus says:] By convention sweet is sweet, by convention bitter is bitter, by convention hot is hot, by convention cold is cold, by convention color is color. But in reality there are atoms and the void. That is, the objects of sense are supposed to be real and it is customary to regard them as such, but in truth they are not. Only the atoms and the void are real.

Boldness is the beginning of action, but fortune controls how it ends

To a wise man, the whole earth is open, because the country of a virtuous soul is the entire universe.
