During the time men live without a common power to keep them all in awe, they are in that conditions called war; and such a war, as if of every man, against every man. To this war of every man against every man, this also in consequent; that nothing can be unjust. The notions of right and wrong, justice and injustice have there no place.
Where there is no common power, there is no law, where no law, no injustice. Force, and fraud, are in war the cardinal virtues. No arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death: and the life of man, solitary, poor, nasty, brutish and short. — Thomas Hobbes.
Thomas Hobbes is known for his contributions to analytic philosophy, writings on ethics, and politics — in particular work Leviathan, looking at the state of society in a post-Tudor time. During his life, where rights of divine order, and duties to church and king were being challenged, his works investigated how social control could be maintained through alternative reasons to simple traditional authorities.
The definition of commonwealth for Hobbes is “one person, of whose acts a great multitude, by mutual covenants one with another, have made themselves every one the author, to the end he may use the strength and means of them all, as he shall think expedient, for their peace and common defence.” He argues that if the world is indeed random, ‘nasty, brutish and [life is] short’, then a social contract should be established to allow for human flourishing; this increased power of the state and law, with an individual’s conscience agreeing to help keep the system together, is the Leviathan — where absolutism is the only rationally defensible form of government.
