The beliefs and behaviour of the Restoration reflect the theories of society put forward by Thomas Hobbes in The Leviathan, which was written in exile in Paris and published in 1651. Like many texts of the time, The Leviathan is an allegory. It recalls mediaeval rather than Renaissance thinking. The leviathan is the Commonwealth, society as a total organism, in which the individual is the absolute subject of state control, represented by the monarch. Man - motivated by self-interest - is acquisitive and lacks codes of behaviour. Hence the necessity for a strong controlling state, 'an artificial man', to keep discord at bay. Self-interest and stability become the keynotes of British society after 1660, the voice of the new middle-class bourgeoisie making itself heard more and more in the expression of values, ideals, and ethics.
