So... think about light when looking at a box.

Not exactly. When you look at the box, you perceive more than its boxiness. You also perceive that it is red, and that it is hard.
-Aron- And you also perceive why. So you basically need to pretend that its "why" is different. It'd be like pretending that it's a ball even though you see that it's a box.
