Introduction

Hume wrote the Treatise in France, partly at La Flèche, and published it anonymously: Books I “Of the Understanding” and II “Of the Passions” in 1739, Book III “Of Morals” in 1740. In the same year he published an anonymous “Abstract” to explain its central argument. The subtitle calls the work an attempt to introduce the experimental method of reasoning into moral subjects. Well-known passages include the claim that reason “is, and ought only to be the slave of the passions” (Book II) and the observation that writers on morality slip from “is” to “ought” without explanation (Book III). Hume later wrote that it “fell dead-born from the press”.
