It is impossible for someone to dispel his fears about the most important matters if he doesn't know the nature of the universe but still gives some credence to myths. So without the study of nature there is no enjoyment of pure pleasure.

Death does not concern us, because as long as we exist, death is not here. And when it does come, we no longer exist.

Tranquil pleasure constitutes human beings' supreme good

I was not, I was, I am not, I care not. (Non fui, fui, non sum, non curo)

Let nothing be done in your life, which will cause you fear if it becomes known to your neighbor.

Any man who does not think that what he has is more than ample, is an unhappy man, even if he is the master of the whole world.

Pleasure is our first and kindred good. It is the starting point of every choice and of every aversion, and to it we always come back, inasmuch as we make feeling the rule by which to judge of every good thing.

It is better for you to be free of fear lying upon a pallet, than to have a golden couch and a rich table and be full of trouble.

It is possible to provide security against other ills, but as far as death is concerned, we men live in a city without walls.

I would rather be first in a little Iberian village than second in Rome.

It is impossible to live a pleasant life without living wisely and honorably and justly, and it is impossible to live wisely and honorably and justly without living pleasantly. Whenever any one of these is lacking, when, for instance, the man is not able to live wisely, though he lives honorably and justly, it is impossible for him to live a pleasant life.

Of all the gifts that wise Providence grants us to make life full and happy, friendship is the most beautiful.

We cannot live pleasantly without living wisely and nobly and righteously.

Misfortune seldom intrudes upon the wise man; his greatest and highest interests are directed by reason throughout the course of life.

You don't develop courage by being happy in your relationships everyday. You develop it by surviving difficult times and challenging adversity.

There is no such thing as justice in the abstract; it is merely a compact between men in their various relations with each other, in whatever circumstances they may be, that they will neither injure nor be injured.

Justice... is a kind of compact not to harm or be harmed.
