Great grief does not of itself put an end to itself.

A friend always loves, but he who loves is not always a friend.

It's a vice to trust all, and equally a vice to trust none.

We must take care to live not merely a long life, but a full one; for living a long life requires only good fortune, but living a full life requires character. Long is the life that is fully lived; it is fulfilled only when the mind supplies its own good qualities and empowers itself from within.

Shall I tell you what the real evil is? To cringe to the things that are called evils, to surrender to them our freedom, in defiance of which we ought to face any suffering.

We should conduct ourselves not as if we ought to live for the body, but as if we could not live without it.

Consider an enemy may become a friend.
