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 what our conception of identity is for various objects over time, which Hume thinks is actually a fiction created by our own mind out of our perceptions, associating them in relation to each other in terms of resemblance, contiguity, and causation. With various objects we may focus on the proportion of changing parts to a whole, the reference of those parts to some common end or purpose, or on the sympathy of parts in mutual cause and effect.
