And here's another twist of citrus in the philosophical brew: The orange I came home with separates neatly into the Orange-in-Itself and the "orange" that I perceived (not to mention consumed). By comparison, the abstract orange I went out to buy, if considered separately from any actual, tangible* orange, has no Orange-in-Itself identity. I wonder if that affects the flavor.

Also: When I eat an orange, I omit the rind. Whereas when I imagine, see, and purchase an orange, it is an object that includes the rind. So the "orange" I eat is the inside of the "orange" I buy. No wonder it's called the Orange-in-Itself!

*Tangerines are even more tangible, of course.
