An Enquiry Concerning Human Understanding is an important 18th century work by Scottish empiricist and philosopher David Hume. As a follow up and attempt to simplify his earlier effort in A Treatise of Human Nature, Hume works to introduce his philosophical concepts to a more well-educated European readership. In this work Hume discusses the limited powers of human understanding, the role of free will in consideration with determinism and the weak foundation of religion. An Enquiry Concerning Human Understanding is highly recommened for those who are interested in major philosophical writings and those who are interested in the writings of David Hume.
