Civilization is a process in the service of Eros, whose purpose is to combine single human individuals, and after that families, then races, peoples and nations, into one great unity, the unity of mankind. Why this has to happen, we do not know; the work of Eros is precisely this. – Sigmund Freud
The first human being who hurled an insult instead of a stone was the founder of civilization. – Sigmund Freud
