Kreeft presents a Socratic examination of Hume's Enquiry concerning Human Understanding in relation to the skepticism of Hume, posing questions that challenge the concepts that Hume proposed. Kreeft states that Hume is the "most formidable, serious, difficult-to-refute skeptic in the history of modern thought." Kreeft invites the reader to take part in the process of refuting Hume's skeptical arguments, with the great insights of Socrates. Based on an imagination dialogue between Socrates and Hume that takes place in the afterlife, this profound and witty book makes an entertaining and informative exploration of modern philosophy.
