  International politics, like all politics, is for Morgenthau a struggle for power because of the basic human lust for power. But regarding every individual as being engaged in a perpetual quest for power—the view that he shares with Hobbes—is a questionable premise. Human nature cannot be revealed by observation and experiment. It cannot be proved by any empirical research, but only disclosed by philosophy, imposed on us as a matter of belief, and inculcated by education.
