Everything existing in the universe is the fruit of chance and necessity.
~ Democritus
Many much-learned men have no intelligence.
No power and no treasure can outweigh the extension of our knowledge.
To a wise and good man the whole earth is his fatherland.
By convention sweet and by convention bitter, by convention hot, by convention cold, by convention color; but in reality atoms and void.
Everywhere man blames nature and fate, yet his fate is mostly but the echo of his character and passions, his mistakes and weaknesses.
[I would] rather discover one cause than gain the kingdom of Persia.
Good means not merely not to do wrong, but rather not to desire to do wrong.
Hope of ill gain is the beginning of loss.
Happiness resides not in possessions, and not in gold, happiness dwells in the soul.
Men should strive to think much and know little.
