When I was twelve years old I thought up an odd trinity: namely, God the Father, God the Son, and God the Devil. My inference wasthat God, in contemplating himself, created the second person of the godhead; but that, in order to be able to contemplate himself, he had to contemplate, and thus to create, his opposite.--With this I began to do philosophy.
Friedrich NietzscheWe do not belong to those who only get their thought from books, or at the prompting of books, -- it is our custom to think in the open air, walking, leaping, climbing, or dancing on lonesome mountains by preference, or close to the sea, where even the paths become thoughtful.
Friedrich NietzscheAt every step one has to wrestle for truth; one has to surrender for it almost everything to which the heart, to which our love, our trust in life, cling otherwise. That requires greatness of soul: the service of truth is the hardest service. What does it mean, after all, to have integrity in matters of the spirit? That one is severe against one's heart...that one makes of every Yes and No a matter of conscience.
