In Hobbes' 'Leviathan,' he argues that in the state of nature, every individual has a 'right of nature'—the liberty to use their own power for the preservation of their own nature, which includes their own life. This implies that individuals possess inherent rights to do whatever they deem necessary for survival. However, because this state is a 'war of all against all,' individuals agree to surrender these rights to a sovereign to ensure security.

Hobbes argued that the sovereign is not a party to the social contract but rather its creation. Because the sovereign does not enter into the covenant with the subjects, they remain outside the contract's constraints, effectively staying in the state of nature while the subjects transition into civil society. This absolute position ensures the sovereign's power remains undivided and supreme, preventing the return to the chaotic state of nature.

Hobbes described the state of nature as a 'war of all against all'. He believed that without a common power to keep them in awe, humans are driven by competition, diffidence, and glory, leading to constant conflict and a life that is 'solitary, poor, nasty, brutish, and short'.

The term 'Leviathan' originates from the Hebrew Bible, specifically appearing in the Book of Job. It describes a powerful, fearsome sea creature that represents chaos and uncontrollable natural forces. Thomas Hobbes adopted this name for his seminal work to symbolize the absolute, all-encompassing power of the state, which is necessary to restrain the chaotic tendencies of human nature in the state of nature.

In Hobbesian political theory, human beings are driven by self-interest and a desire for self-preservation. Because the state of nature is inherently dangerous, individuals enter into a social contract. The fear of the sovereign's power and the consequences of violating the law act as the primary deterrent, ensuring that individuals comply with societal norms and maintain the peace established by the Leviathan.

This critique often targets Thomas Hobbes. While Hobbes advocates for an absolute sovereign that suppresses individual dissent, his political framework is rooted in the rational, self-interested individual of the state of nature. This paradox—using individualistic premises to justify an absolute, anti-individualistic state—is a central theme in critiques of Leviathan.

Thomas Hobbes argued that sovereignty must be absolute to be effective. He believed that if power were divided or limited, it would lead to conflict and the collapse of the state into a state of nature. Therefore, the sovereign must possess total authority over law, religion, and military force to ensure the security and survival of the commonwealth.

In Hobbes' political philosophy, the sovereign is not a party to the social contract but rather its creation. Because the sovereign does not surrender any rights to a higher authority, they remain in the state of nature, possessing absolute power while the subjects are bound by the covenant to obey.

Thomas Hobbes viewed reason as a natural faculty of the human mind, which he famously described as 'reckoning' or 'calculating' the consequences of actions. For Hobbes, reason is an innate ability that allows individuals to navigate the state of nature and eventually agree to the social contract. While he emphasizes the role of language and convention, the underlying capacity for rational thought is considered a natural human attribute.

While many scholars like T.H. Green and Vaughan criticized the historical and logical foundations of the Social Contract Theory, Karl Marx focused his critique on the economic and class-based structures of society rather than engaging directly with the contractualist framework of the state's origin.
