[5] In developing his moral and political philosophy, Hobbes assumes the methodological approach of deductive reasoning, combining mathematics and the mechanics of science to formulate his ideas on human nature.
[1] Hobbes was critical of the assumptions of scholastic philosophers, whose evidence for human nature was based upon Aristotelian metaphysics and Cartesian observation, as opposed to reasoning and definition.
[5] This scientific method stresses the importance of first establishing well-defined principles of human nature (moral philosophy) and ‘deducing’ aspects of political life from this.
[1] Hobbes first used the mechanics of motion to define principles of human perception, behaviour and reasoning, which were then used to draw the conclusions of his political philosophy (sovereignty, state of nature).
[3] Hobbes’s moral principles thus provide the ultimate basis for his political philosophy, defining and clarifying how an “artificial” sovereign authority may come into existence.
This moral philosophy outlines a general conceptual framework on human nature which is rigorously developed in The Elements of Law, De Cive and Leviathan.
[5] The Elements of Law provides insight into Hobbes’s moral philosophy through ideas of sensation, pleasure, passion, pain, memory and reason.
[6] Hobbes believes that as sensory organs process the movements of external stimuli, a range of different mental experiences take place, which in turn dictate human behaviour.
[4] Reason, or “ratiocination”, as used by Hobbes, was not defined in the traditional sense as an innate capability tied to notions of natural law, but as an activity that involved coming to a judgement via the process of logic.
[6] Because human beings will always pursue what is ‘good’ for them, this philosophy asserts that individuals share overarching desires or goals, such as security and safety (especially from death).
[3] The notion that individuals require a “visible power to keep them in awe” - to maintain peace and safety through enforcement of law - underpins Hobbes’s theory of sovereignty, which proposes that a sovereign ruler (with authority to govern the people) is fundamental to any type of commonwealth.
[10] Therefore, the overarching concern of Hobbes’s political philosophy remains the capacity of the government to maintain peace, protection, justice and wellbeing in a manner that ensures the continuation of society and civil life.
