I've often wondered what people mean when they talk about an experience. I'm a technologist and accustomed to seeing things as they are. I see everything they are talking about very clearly; after all, I'm not blind. I see the moon over the Tamaulipas desert--it is more distinct than at other times, perhaps, but still a calculable mass circling around our planet, an example of gravitation, interesting, but in what way an experience? I see the jagged rocks, standing out black against the moonlight; perhaps they do look like the jagged backs of prehistoric monsters, but I know they are rocks, stone, probably volcanic, one should have to examine them to be sure of this. Why should I feel afraid? There aren't any prehistoric monsters any more. Why should I imagine them? I'm sorry, but I don't see any stone angels either; nor demons; I see what I see--the usual shapes due to erosion and also my long shadow on the sand, but no ghosts. Why get womanish? I don't see any Flood either, but sand lit up by the moon and made undulating, like water, by the wind, which doesn't surprise me; I don't find it fantastic, but perfectly explicable. I don't know what the souls of the damned look like; perhaps like black agaves in the desert at night. What I see are agaves, a plant that blossoms once only and dies. Furthermore, I know (however I may look at the moment) that I am not the last or the first man on earth; and I can't be moved by the mere idea that I am the last man, because it isn't true. Why get hysterical? Mountains are mountains, even if in a certain light they may look like something else, but it is the Sierra Madre Oriental, and we are not standing in a kingdom of the dead, but in the Tamaulipas desert, Mexico, about sixty miles from the nearest road, which is unpleasant, but in what way an experience? Nor can I bring myself to hear something resembling eternity; I don't hear anything, apart from the trickle of sand at every step. Why should I experience what isn't there?
