Sex is the greatest magic force of nature. Its actions prefigure the mystery of the One. Plato and Orwell are two cases in which ideology distorts the sense of sexuality. Two thinkers of the XXth century, Julius Evola and Michel Foucault, represent two different perspectives for a philosophy of sexuality – a metaphysics and a history of conscience, but the ideology must be sought where we see too much freedom or no freedom at all. And for that, we have two moments: Woodstock (1969) and Communism.
