This lecture discusses key ideas from the 18th century philosopher, essayist, and historian, David Hume's work A Treatise of Human Nature Specifically it examines his final portion of the discussion, where he turns back to considering the notion we have of personal identity and an identifiable "self" that runs throughout a person's entire life. Hume considers this a fiction and inquires as to how this fictitious idea comes to be in our minds. A significant part of his answer has to do with the main ways in which ideas are associated: resemblance, contiguity, and causality.
