A Treatise of Human Nature

David Hume was born in Edinburgh to a minor Scottish noble family, raised at the estate of Ninewells, and attended the University of Edinburgh for two years until he was 15. Although his family wished him to study law, he found himself unsuited to this.

During this period, he completed the Dialogues Concerning Natural Religion, which he had been working on for more than 25 years. Hume first worked on the Dialogues in the middle of his career, but put them aside as too
