Sapiens is a distinctly nihilist tract, rejecting every sort of theism, every claim that life has meaning, and every assertion of human rights. According to Harari, there’s nothing the least bit sacred about human life, the Declaration of Independence is in error about liberty and equality, and the word “nature” itself—as in human nature—is meaningless. Insofar as Sapiens is a work of philosophy, it’s Nietzchean in its rejection of the most central human values, as well as in its suggestion that a superman—created by genetic or “inorganic” engineering—may be on the way.
