“As I raised the knife, the sharp edge near my hand appeared crimson; as if it were bloody in the grooves. The effect quickly passed; but I returned the knife to the previous position, and then realized that … the blade was never bloody … nor was I hallucinating, per se. I was wearing a red shirt. And that hue was reflected in the serrations of the blade … but only at a specific angle of light.

As I realized this I thought how thought itself is thus: I see an effect, and believe it. Because, in my mind, I cannot easily see the implements with which I cut and join the elements. I cannot tell reflection from source… in fact, I cannot see my mind’s hands, or their movements, either.”
