" According to existential-humanist psychology, where the materialist says "I perceive," it would be more correct to say "I am making a bet.” Concretely, in Ames's cock-eyed room, we "make a bet" that we are seeing something familiar to us. If allowed into the room and asked to touch a corner of the ceiling with a pointer, we quickly discover the gamble in every act of perception. Typically, we hit almost everything but the corner in our first attempts — the walls, other parts of the ceiling, etc. A strange thing happens as we go on trying. Our perceptions change — we are making a new series of bets, one after another — and gradually we are able to find the corner we are aiming for. "
