I have stubbornly resisted the idea that our own kind is
special in the capabilities of our hearts or minds. Other animals
also have hearts and minds and it is narrow-minded to assume that
they do not use them in the same ways we use ours. Our record of
intelligence is not matched by our ability to control and to
manufacture; other animals have better histories of survival
without killing others or destroying the environment that their
survival depends on. The fact that Cro-Magnon and Neanderthals are
gone today does not show that they were incapable of surviving,
accepting the possibility that our ancestors killed them. Our
record of narrow-mindedness and lack of sympathy to others is well
established and might be blinding us to the fact that they are us.
The discoveries of Édouard and Louis Lartet did a
little to overthrow our self-centeredness.
