When I realized this, I grabbed on to it like a life raft, and I haven’t let go. This is real. Your eyes reading this text, your hands, your breath, the time of day, the place where you are reading this—these things are real. I’m real too. I am not an avatar, a set of preferences, or some smooth cognitive force; I’m lumpy and porous, I’m an animal, I hurt sometimes, and I’m different one day to the next. I hear, see, and smell things in a world where others also hear, see, and smell me.
