Loyalty to life, according to Nietzsche, begins in the resolve to seek life's principle with itself and not in something outside it—not, for example, in a God or supernature that, by being conceived as all that life is not—infinite, eternal, changeless, perfect goodness, perfect plenitude—stands as antithetical to life.
