The rust of the mind is the destruction of genius.
There is no evil that does not offer inducements. Vices tempt you by the rewards which they offer.
Injustice never rules forever.
If a man knows not to which port he sails, no wind is favorable.
The man who while he gives thinks of what he will get in return, deserves to be deceived.
When one is friend on himself, also is friend of everybody.
