Answer
Michel Onfray's philosophical perspectives are primarily indebted to the ideas of Nietzsche, Epicurus, and French materialists. Nietzsche's influence can be seen in Onfray's emphasis on the individual and the affirmation of life, while Epicurus's philosophy provided Onfray with ethical insights on pleasure and freedom from fear. Additionally, Onfray draws inspiration from French materialists, particularly their critique of religion and their focus on the material world.
