Pufendorf was educated at Leipzig and Jena, and was appointed professor of natural law at Lund, in Sweden. His great work was the De Jure Naturae et Gentium (1672, trs. as Of the Law of Nature and Nations, 1710). Influenced by Descartes, Hobbes, and the scientific revolution of the 17th century, Pufendorf’s ambition was to introduce a newly scientific ‘mathematical’ treatment of ethics and law, free from the tainted Aristotelian underpinnings of scholasticism. Like that of his contemporary Locke, his conception of natural law includes rational and religious principles, making it only a partial forerunner of more resolutely empiricist and political treatments in the Enlightenment.
