He who is not satisfied with a little, is satisfied with nothing .

Of all the means to insure happiness throughout the whole life, by far the most important is the acquisition of friends.

Vain is the word of a philosopher which does not heal any suffering of man. For just as there is no profit in medicine if it does not expel the diseases of the body, so there is no profit in philosophy either, if it does not expel the suffering of the mind.

Neither one should hesitate about dedicating oneself to philosophy when young, nor should get tired of doing it when one's old, because no one is ever too young or too old to reach one's soul's healthy.

It is not the young man who should be considered fortunate but the old man who has lived well, because the young man in his prime wanders much by chance, vacillating in his beliefs, while the old man has docked in the harbor, having safeguarded his true happiness.

The acquisition of riches has been for many men, not an end, but a change, of troubles.

I was not; I have been; I am not; I do not mind.
