The truth is always the strongest argument.
Stubbornness and stupidity are twins.
Fortune raises up and fortune brings low both the man who fares well and the one who fares badly; and there is no prophet of the future for mortal men.
For this I see, that we, all we that live, Are but vain shadows, unsubstantial dreams.
Man's worst ill is stubbornness of heart.
Do not grieve yourself too much for those you hate, nor yet forget them utterly.
