I still can't really get over the part where "sensation" (which seems deeply personal and individualized to me) is a way to experience something universal (but that's my beef with Locke, not necessarily Hume, so we'll see!).

But isn't this all knowledge, according to Locke's tabula rasa and Hume's empiricism?
