Conflict theories are perspectives in sociology and social psychology that emphasize a materialist interpretation of history, dialectical method of analysis, a critical stance toward existing social arrangements, and political program of revolution or, at least, reform. Conflict theories draw attention to power differentials, such as class conflict, and generally contrast historically dominant ideologies. It is therefore a macro-level analysis of society. Karl Marx is regarded as the father of social conflict theory, which is a component of the four major paradigms of sociology. Certain conflict theories set out to highlight the ideological aspects inherent in traditional thought. While many of these perspectives hold parallels, conflict theory does not refer to a unified school of thought, and should not be confused with, for instance, peace and conflict studies, or any other specific theory of social conflict. Of the classical founders of social science, conflict theory is most commonly associated with Karl Marx (1818–1883). Based on a dialectical materialist account of history, Marxism posited that capitalism, like previous socioeconomic systems, would inevitably produce internal tensions leading to its own destruction. Marx ushered in radical change, advocating proletarian revolution and freedom from the ruling classes, as well as critiqued political economy. At the same time, Karl Marx was aware that most of the people living in capitalist societies did not see how the system shaped the entire operation of society. Just as modern individuals see private property (and the right to pass that property on to their children) as natural, many of the members in capitalistic societies see the rich as having earned their wealth through hard work and education, while seeing the poor as lacking in skill and initiative. Marx rejected this type of thinking, viewing it as something Friedrich Engels termed false consciousness, the use of misdirection by the ruling class to obfuscate the exploitation intrinsic to the relationship between the proletariat and the ruling class.
