The love of wisdom “ philo sophia ” this is the meaning of philosophy according to its Greek etymology. But this love, Nietzsche intimates, is not the end of the story. The truth is that there is only one woman that we love dearly, and this woman is Life. Even though we always betray her, and even though we always want to leave her, she is the one we truly cherish, in sickness and in health, until Death do us part. Philosophy is always about living and being alive. Philosophy is, properly speaking, the love of life.
