However, to understand the disparity between political thought, it was necessary to describe the primary ideas. While the central purpose of Rousseau's writings was to explain how the freedom of the individual can integrate with the authority of the State. Hobbes illustrated the need for political societies which he calls Leviathan, with the aim of saving the terrible and natural state of man. Although both agree with the inherent equality of men, Hobbes believes that men are intrinsically evil and must be governed by a higher power. In contrast, Rousseau believes that men are born with the potential for goodness, but the social systems in place propagate animosity. Although Hobbes and Rousseau are both concerned with self-preservation, Hobbes supports the idea of ​​an authoritarian regime governing men to prevent a state of war, and Rousseau specifies that freedom consists in men making their own laws. Years later, many of the problems related to inequality and the nature of men are still relevant in our societies. Hobbes and Rousseau had a profound impact on the world of philosophy with their arguments and theories. Despite their differences, both dominant intellectual figures wrote these texts with the central objective of highlighting the conditions necessary for the existence of an ideal and ideal society and governing body.
