I watched the gorilla's eyes again, wise and knowing eyes, and wondered about this business of trying to teach apes language. Our language. Why? There are many members of our own species who live in and with the forest and know it and understand it. We don't listen to them. What is there to suggest we would listen to anything an ape could tell us? Or that it would be able to tell us of its life in a language that hasn't been born of that life? I thought, maybe it is not that they have yet to gain a language, it is that we have lost one.
