The truly learned man is he who understands that what he knows is but little in comparison with what he does not know.

The man of learning lives even after his death: the ignorant man is dead, while still alive.

Books are the gardens of the learned.

A man is a believer as long as he is virtuous.

Virtue is the key to success.

The most detestable man is he who returns evil for good, and the most praiseworthy, he whose answer to villainy is a generous deed.

The wicked man thinks no good of any one; for how should he imagine that others have what he lacks himself?

The worst man is the one who sees himself as the best.

Men are asleep: they will awake when they die.

Men are like trees; though the water with wich they are watered is the same yet the fruits are not alike.
