“All I can do is think with my mind. All I can be is who I seem to myself. I can only be where it seems that I am. Time seems to move quickly or slowly, but it is time all the same; my wristwatch proves it. I believe my wristwatch exists, and even when I am unconscious, it is ticking all the same. You have to start somewhere. It is within these assumptions that I must live. Even if everything everywhere is the same, I must eat an orange or I will die of scurvy.”

-Roger Ebert.
