If intelligence is just a matter of evolution, what happens when a bunch of species get to a similar point at the same time? We are unhappy to find ourselves the only intelligent animals on our planet. It would be so interesting if we could find others. We can’t. But suppose we could: suppose the lion was intelligent and the deer were also intelligent. It’s very hard to imagine. You have to have sympathy with both. The lion cannot eat grass no matter how much you would like him to. But the deer do not wish to be eaten, and who can blame them for it?
