An Enquiry concerning Human Understanding is a book by the Scottishempiricist and philosopherDavid Hume, published in 1748. It was a simplification of an earlier effort, Hume's A Treatise of Human Nature, published anonymously in London in 1739–1740. Hume was disappointed with the reception of the Treatise (it "fell dead-born from the press", as he put it) and so tried again to disseminate his ideas to the public by writing a shorter and more polemical work.
