Scottish philosopher Thomas Brown (1778-1820) held the chair of moral philosophy at the University of Edinburgh. He was distinguished for his work in the philosophy of mind and causation, and was a founder member of the Edinburgh Review. At the beginning of the nineteenth century, controversy arose over John Leslie being appointed to the chair of mathematics at the university. City ministers opposed him because he defended Hume's view of causation, which was seen as being incompatible with the existence of God. In 1805 Brown wrote a pamphlet, Observations on the Nature and Tendency of the Doctrine of Mr. Hume Concerning the Relation of Cause and Effect, which among other things aimed to show that Hume's theory was compatible with belief in God. This book, first published in 1818, is the third edition of that original pamphlet, which grew to become a thorough examination of the philosophy of causation.
