"Nietzsche's rejection of a rational morality is based on his rejection of a utilitarian morality; it is precisely the binding of man to arbitrary, even absurd laws, to laws which serve no particular benefit, that is the character of morality. Religion, premodern polytheism then, cannot emerge out of a utilitarian morality as in the model of Hume. Peoples themselves are the result of the founding acts of creative prophets; much as in Rousseau, Nietzsche believes such prophets or founders—legislators in the highest sense—are the origin therefore of mores and conventions by which peoples live. In this task the founder uses religion, but the religious experience of such founders, and by extension religious experience in general, is therefore not reducible to calculation of benefit or of self-interest."
