There are four questions of value in life, Don Octavio. What is sacred? Of what is the spirit made? What is worth living for and what is worth dying for? The answer to each is the same. Only love.
My formula for greatness in a human being is amor fati: that one wants nothing to be other than it is, not in the future, not in the past, not in all eternity.
Such philosophy as shall not vanish in the fume of subtile, sublime, or delectable speculation but shall be operative to the endowment and betterment of man's life.
