Plutarch

Those who aim at great deeds must also suffer greatly.

Nothing is harder to direct than a man in prosperity; nothing more easily managed that one is adversity.

Moral habits, induced by public practices, are far quicker in making their way into men's private lives, than the failings and faults of individuals are in infecting the city at large.

It is part of a good man to do great and noble deeds, though he risk everything.

We ought not to treat living creatures like shoes or household belongings, which when worn with use we throw away.

Courage consists not in hazarding without fear; but being resolutely minded in a just cause.

Perseverance is more prevailing than violence; and many things which cannot be overcome when they are together, yield themselves up when taken little by little.

Courage stands halfway between cowardice and rashness, one of which is a lack, the other an excess of courage.

It is indeed a desirable thing to be well-descended, but the glory belongs to our ancestors.

Medicine to produce health must examine disease; and music, to create harmony must investigate discord.

Do not speak of your happiness to one less fortunate than yourself.

Silence at the proper season is wisdom, and better than any speech.
