Consider in silence whatever any one says: speech both conceals and reveals the inner soul of man.

Don't promise twice what you can do at once.

Consider it the greatest of all virtues to restrain the tongue.

Blessed be they as virtuous, who when they feel their virile members swollen with lust, visit a brothel rather than grind at some husband's private mill.

The best way to keep good acts in memory is to refresh them with new.

Should anyone attempt to deceive you by false expressions, and not be a true friend at heart, act in the same manner, and thus art will defeat art. [If you would catch a man let him think he is catching you.]

This is my firm persuasion, that since the human soul exerts itself with so great activity, since it has such a remembrance of the best, such a concern for the future, since it is enriched with so many arts, sciences, and discoveries, it is impossible but the being which contains all these must be immortal.
