Often described as the father of the Scottish Enlightenment, Francis Hutcheson (1694–1746) was born in the north of Ireland to an Ulster-Scottish Presbyterian family. Organised into three 'books' that were divided between two volumes, A System of Moral Philosophy was his most comprehensive work. It synthesised ideas that he had formulated as a minister and as the Chair of Moral Philosophy at the University of Glasgow (1729–46). Published posthumously by his son in 1755, prefaced by an account of his life, it is the only treatise by Hutcheson for which a manuscript is known to have survived. Asserting that individual natural rights derive from an innate understanding of moral behaviour, Hutcheson offers a model that mediates between individual interests and communal ideals. Containing Book 1 and part of Book 2, Volume 1 describes the role and perception of 'perfect' and 'imperfect' natural rights.
