The most extraordinary dream I ever had was one in which I fancied that, as I was going into a theater, the cloak-room attendant (21) me in the lobby and insisted on my (22) my legs behind. I was not surprised; but I was considerably annoyed. I said I had (23) heard of such a rule at any respectable theater (24) , and that I considered it a most absurd regulation. The man replied that he was very (25) , but that those were his instructions. People complained that they could not get to and from their (26) comfortably, because other people’s legs were always in the (27) ; and it had, therefore, been decided that (28) should leave their legs outside. It seemed to me that the management, in making this order, had gone (29) their legal right; and, under ordinary circum- stances, I should have disputed it. However, I didn’t want to (30) a disturbance; and (31) I sat down and meekly prepared to comply with the demand. I had never before (32) that the human leg could be unscrewed. I had always (33) it was more securely fixed. But the man showed me how to undo them, and I found that they came off (34) easily. The discovery did not surprise (35) any more than the original request that I should take them off. Nothing does surprise one in a dream.

Research on animal intelligence always makes us wonder just how smart humans are. Consider the fruitfly experiments described by Carl Zimmer in the Science Times. Fruits flies who were taught to be smarter than the average fruit fly31to live shorter lives. This suggests that32bulbs burn longer, that there is an advantage in not being too bright.
Intelligence, it turns out, is a highpriced option. It takes more upkeep, burns more fuel and is slow 33 the starting line because it depends on learning a (an)34process instead of instinct. Plenty of other species are able to learn, and one of the things theyve apparently learned is when to stop.
Is there an adaptive value to35intelligence Thats the question behind this new reach. Instead of casting a wistful glance backward at all the species weve left in the dust. I.Q.wise, it implicitly asks what the real36of our own intelligence might be. This is on the mind of every animal weve ever met.
Research on animal intelligence also makes us wonder what experiments animals would37on humans if they had the chance. Every cat with an owner, for instance, is running a smallscale study in operant conditioning. We believe that38animals ran the labs, they would test us to determine the limits of our patience, our faithfulness, our memory for location. They would try to decide what intelligence in humans is really for, not merely how much of it there is.39, they would hope to study a fundamental question: Are humans actually aware of the world they live in40the results are inconclusive.
