How much luckier than all the rest of mankind are the astrologers who, if they tell one truth among a hundred lies, obtain so much credit that even their lies are believed.
Francesco GuicciardiniBe careful how you do one man a pleasure which must needs occasion equal displeasure in another. For he who is thus slighted will not forget, but will think the offence to himself the greater in that another profits by it; while he who receives the pleasure will either not remember it, or will consider the favour done him less than it really was.
Francesco GuicciardiniHe is less likely to be mistaken who looks forward to a change in the affairs of the world than he who regards them as firm and stable.
