Leviathan, published in 1651 by Thomas Hobbes, is a foundational text in Western political philosophy. Written during the turbulence of the English Civil War, the book presents a systematic theory of civil government, grounded in Hobbes’s broader philosophical views on human nature, social order, and authority. It is divided into four parts: “Of Man,” “Of Commonwealth,” “Of a Christian Commonwealth,” and “Of the Kingdom of Darkness.”
In the first part, “Of Man,” Hobbes sets out his theory of human nature using a mechanistic and materialist framework. He argues that all phenomena, including human thought and behavior, result from the movement of matter. According to Hobbes, human actions are driven by appetites and aversions, particularly the desire for self-preservation. In the absence of a common authority, individuals would act solely according to their own interests, leading inevitably to a condition of conflict and insecurity. This hypothetical condition, which Hobbes calls the “state of nature,” is characterized by continuous fear and the danger of violent death. Life in this state, he famously writes, would be “solitary, poor, nasty, brutish, and short.”
To escape the state of nature, individuals collectively agree to form a civil society through a social contract. In doing so, they transfer their individual rights to a central authority, the “sovereign,” in exchange for peace and security. This agreement is the basis of Hobbes’s second part, “Of Commonwealth,” where he outlines the structure and functions of a legitimate state. The sovereign—whether a monarch, assembly, or other form—is given absolute authority to make and enforce laws. Hobbes argues that this concentration of power is necessary to prevent a return to the anarchy of the state of nature. Once established, the sovereign’s authority is irrevocable, and subjects have no right to rebel.
Hobbes does not base his argument for sovereignty on divine right but on rational self-interest and mutual consent. He emphasizes that the legitimacy of political authority comes from the agreement of individuals seeking to avoid the dangers of an ungoverned life. The sovereign’s primary responsibility is to ensure peace, security, and the enforcement of contracts. Although Hobbes acknowledges that tyrannical rule may occur, he believes that the risks of rebellion or civil war are worse than the potential abuses of sovereign power.
In the third part, “Of a Christian Commonwealth,” Hobbes addresses the relationship between religion and politics. He argues that religious authority must be subordinate to civil authority to avoid conflict and disorder. Hobbes interprets Scripture in a way that supports political stability, asserting that the sovereign has the final say in interpreting religious doctrine within the state.
The final part, “Of the Kingdom of Darkness,” is a critique of institutions and doctrines that, in Hobbes’s view, undermine political order. He targets scholastic philosophy, clerical authority, and superstition as sources of confusion and conflict that threaten the rational foundations of a well-ordered commonwealth.
Overall, Leviathan presents a political theory based on a pessimistic view of human nature and the necessity of a strong, centralized authority. Hobbes’s argument for absolute sovereignty, justified by a rational social contract, marks a significant departure from earlier theories based on divine right. His work has had a lasting impact on political thought, particularly in the development of modern theories of state legitimacy, authority, and individual rights. Leviathan remains a key text in understanding the evolution of political philosophy and the justification of governmental power.
