Nietzsche's Argument for a True Truth

Nietzsche laments the mass because with it comes a kind of heard like submission to what he calls slave morality, which we'll get into in a bit. He says that if there actually existed a truth, this truth would certainly not be communicable to the public at large as Christianity is or Platonism is. To anyone who hasn't submitted to the heard or hasn't submitting to the masses, this is a person who's going to most likely exist in isolation.
