There are a lot of obstacles in the way of our understanding animal intelligence - not the least being that we can't even agree whether nonhuman species are conscious. We accept that chimps and dolphins experience awareness we like to think dogs and cats do. But what about mice and newts? What about a fly? Is anything going on there at all?
The structure of life I have described in buildings - the structure which I believe to be objective - is deeply and inextricably connected with the human person and with the innermost nature of human feeling.
