«An Enquiry Concerning Human Understanding» by David Hume

An Enquiry Concerning Human Understanding is a revision of an earlier Hume's work, Treatise of Human Nature, published anonymously in London in 1739–40. Hume was disappointed with the reception of the Treatise, which "fell dead-born from the press," as he put it, and so tried again to disseminate his more developed ideas to the public by writing a shorter and more polemical work.
