Jean-Jacques Rousseau, the influential Genevan philosopher, provocatively argued in his Discourse on the Origin and Basis of Inequality Among Men (1755) that inequality is not a natural state of humanity but rather a construct of society, particularly stemming from the institution of private property. He distinguished between two forms of inequality: natural or physical inequality, which he saw as arising from differences in age, health, and strength, and moral or political inequality, which he attributed to consent and is established through human agreement. Rousseau’s central thesis is that it is this latter, socially manufactured inequality that has led to vice, conflict, and the corruption of human nature, a stark departure from earlier thinkers who often viewed hierarchy as inherent or even beneficial.
Rousseau traces the development of inequality through a hypothetical state of nature, where early humans, or "savages," lived solitary, independent lives guided by self-preservation and pity. In this state, there was little room for significant disparities. Individuals were largely self-sufficient, their needs were minimal, and competition, while existing, did not lead to systematic dominance. However, Rousseau identifies a crucial turning point with the emergence of "l'amour-propre," or vanity, a social sentiment that arises from comparing oneself to others. This sentiment, he argues, is nurtured by the development of language, social interaction, and the establishment of families and communities, which foster a sense of dependence and the desire for recognition.
The most significant catalyst for profound inequality, according to Rousseau, was the invention of private property. He famously declared in the Discourse that the first person who enclosed a piece of land and declared it his own, and found people simple enough to believe him, was the true founder of civil society and, by extension, of inequality. This act, he contended, created artificial needs and desires, fueled by envy and the pursuit of possessions. As societies grew, so did the complexity of social relations and the need for rules and governance. This led to the formation of laws and political institutions, which, instead of protecting the weak, primarily served to secure the property of the rich and powerful. Rousseau saw the establishment of government as a "fatal project" that legitimized and perpetuated the inequalities created by property ownership, transforming brute force into right and the industrious into slaves.
Rousseau’s critique extends to the notion of progress. He argued that advancements in arts, sciences, and technology, often celebrated as markers of civilization, had actually contributed to the degradation of human virtue and the amplification of social disparities. The refinement of manners and the pursuit of luxury masked underlying corruption, while the dependence on social approval stifled genuine freedom and autonomy. The social contract, as conceived by many thinkers, was, for Rousseau, often a pact that benefited the oppressor rather than the oppressed. He envisioned a different kind of social contract, one based on the general will of the people, where individuals would surrender their individual wills to a collective sovereign, thereby achieving a higher form of freedom through association.
In conclusion, Rousseau’s examination of inequality offers a powerful indictment of civil society as he found it. By dissecting the origins of social stratification, he argued that it is not a natural condition but an artificial construct born from property, vanity, and flawed social contracts. His work profoundly influenced subsequent political thought, providing a foundational critique that resonates in modern discussions of social justice, economic disparity, and the role of government in mitigating the negative consequences of societal structures.
