"A genuine Nietzsche study would require the psychology of religion that would spotlight the meaning of his being, his suffering, and his self-induced bliss. His entire development, as it were, derived from his loss of belief and therefore from his emotions that attend the death of God. These tremendous emotions reverberate in his writings up to the final work, the fourth part of Also Sprach Zarathustra, which was composed on the threshold of madness. The possibility of finding some substitutions for the lost God by means of the most varied forms of self-idolization constituted the story of his mind, his works, and his illness. (p. 26)"
