When, however, you have an enemy, then do not requite him good for evil: for that would shame him. Instead, prove that he did some good for you. And rather be angry than put to shame! And when you are cursed, I do not like it that you want to bless. Rather curse a little also! And if you are done a great injustice, then quickly add five small ones. Hideous to behold is he who is obsessed with an injustice.
Friedrich NietzscheThe misunderstanding of passion and reason, as if the latter were an independent entity and not rather a system of relations between various passions and desires; and as if every passion did not possess its quantum of reason.
Friedrich Nietzsche
