Communist Manifesto examines the theory and goals expounded by Karl Marx. Marx argues that history flows inevitably toward a social revolution, which will result in a society without economic classes. The influence on Marx of Hegel, Feuerbach, and other philosophers is examined, as is his friendship and collaboration with Engels.Social Contract, by Rousseau, argues that people secure their liberty by entering into an implied contract with government. Rather than being protected by natural rights, their liberty is secured by the "general will", one of the most famous and troublesome ideas in political theory. This presentation explores Rousseau's concept of social order and its implications for individual freedom and the good of society.
