Consider Sigmund Freud's treatment of aggression as a core aspect of the human psyche in Civilization and Its Discontents, and compare it with Plato's discussion of "spirit" and courage in Republic. Does "spirit" present the same dangers and problems that Freud attributes to aggression? How does Freud explain civilization's defense against aggression, and would Plato agree with Freud's suggestion that this defense can be a potent cause of unhappiness? Cite specific passages in the works to show agreement or incongruity in our authors' views on the effect and management of aggression in society.
