Johann Gottlieb Heineccius 
A Methodical System of Universal Law 
Or, the Laws of Nature and Nations; With Supplements and a Discourse by George Turnbull

George Turnbull’s eighteenth-century translation of A Methodical System of Universal Law was his major effort to convey continental natural law to Britain, thus making Heineccius’s natural jurisprudence more accessible to English-speaking audiences. Turnbull includes extensive comments on Heineccius’s text and also presents his own philosophical work, A Discourse upon the Nature and Origin of Moral and Civil Laws.

Johann Gottlieb Heineccius (1681–1741) studied theology at Leipzig and later law at the newly founded (1694) University of Halle, where he became a pupil of Christian Thomasius.
