David Hume, an eminent Scottish philosopher, historian, and essayist, explores the nature and foundation of Morals in this book, which was written as a popular summary of Book III in A Treatise of Human Nature. Hume states: “There has been a controversy started of late, much better worth examination, concerning the general foundation of Morals; whether they be derived from Reason, or from Sentiment; whether we attain the knowledge of them by a chain of argument and induction, or by an immediate feeling and finer internal sense; whether, like all sound judgement of truth and falsehood, they should be the same to every rational intelligent being; or whether, like the perception of beauty and deformity, they be founded entirely on the particular fabric and constitution of the human species.” (Excerpted from Section I – Of the General Principles of Morals) (Summary from the text and adapted from Wikipedia by lubee930)
