"The question of whether or not, when you see something, you see only the light or you see the thing you're looking at, is one of those dopey philosophical things that an ordinary person has no difficulty with. Even the most profound philosopher, when sitting, eating his dinner, hasn't any difficulty in making out that what he looks at perhaps might be only the light from the steak, but it still implies the existence of the steak, which he is able to lift by the fork to his mouth. The philosophers that were unable to make that analysis and that idea, have fallen by the wayside through hunger!"
