I asked him; or rather, I stared at it until he told me what it was; I explained that I couldn't quite make sense of the shapes and colors I was seeing and figure out what it could be in the bowl (first he thought I just wanted some). He said something like "Oh, your transcendental apperception failed you." (btw, it was a cut-up greenish-yellow melon)
Me: What the [bleep] is apperception?
Him: Transcendental apperception is . . .
Me: No, just what is apperception?
Him: That's what I'm telling you.
Me: No, you're telling me about transcendental apperception!
Him: That's the only kind of apperception there seems to be in Kant!
Me: We're not in Kant!
Him: Ah, that's where you're wrong . . .
