"It seems to me that every time we think we've narrowed in on what the crucial difference between humans and the rest of the animals is, we turn out to be wrong again. I remember when man was the tool-using animal. Now we know that many animals use tools. Chimps have a theory of mind. Scrub jays evidence episodic memory. We have underestimated our fellow animals at every turn, mainly by being unable to see beyond ourselves. It would be nice if we could stop doing that."
