"Discourse on the Origin of Inequality" is a philosophical work by Jean-Jacques Rousseau, first published in 1755. In this essay, Rousseau explores the origins and nature of inequality among humans, attempting to uncover the underlying causes and implications of social disparities. Rousseau argues that natural inequality stems from physical differences among individuals, such as strength and intelligence. However, he distinguishes this from moral or political inequality, which arises from the development of society and the establishment of property, laws, and social institutions. According to Rousseau, these societal developments lead to the emergence of inequality, as some individuals acquire wealth, power, and privilege at the expense of others. Rousseau further contends that the advent of private property and the formation of civil society exacerbate inequality, as they create divisions and conflicts among people. He criticizes the social contract theory of his contemporaries, arguing that the establishment of political authority and laws serve to perpetuate inequality rather than promote the common good. Overall, "Discourse on the Origin of Inequality" is a foundational text in political philosophy and social theory, raising fundamental questions about the nature of human society, the origins of inequality, and the legitimacy of political authority. Rousseau's ideas have had a significant influence on subsequent thinkers and movements, shaping discussions on democracy, justice, and social reform.
