Knowledge as Object

I am temped to think of knowledge as an object that can be stored in my mind-brain box. As if I could open the box and see my collection of facts. So, right now, I draw the fact 'My bedroom is painted yellow' to me. But could I really be picking up this fact from some internal box? I am trapped in a spacial metaphor.

Then, I ask, when did I know this fact? After I called it before me? Before? Since the moment I first percieved the room to be yellow? I am trapped in a temporal metaphor. (Note: this is not to say that knowledge is time-independent. Obviously, I know some things now and not others. This will change in the future; I learn.)
