It is now generally accepted that the roots of our ethics lie in patterns of behavior that evolved among our pre-human ancestors, the social mammals and that we retain within our biological nature elements of these evolved responses. We have learned considerably more about these responses, and we are beginning to to understand how they interact with our capacity to reason.

The path of the PROUN does not lie within the narrowly limited, fragmented, and isolated scientific disciplines - the builder consolidates them all together in his own experimental investigation. The path of the PROUN is not the incoherent approach of separate scientific disciplines, theories, and systems, but is rather the straightforward path of learned influence over reality.

Ever since Darwin tied knots between human beings and the rest of the animal world, many people have frantically attempted to untie them again, declaring that even though our roots are in the animal world we have left them so far behind as to make any comparisons utterly meaningless. To some extent this is true, because the quality that makes us unique in the biological kingdom is the enormous capacity to learn.

And by the way, the theory of evolution was popular way before Darwin; he just made it more popular. Aristotle taught a form of evolution in 400 B. C. The Egyptians taught evolution to Moses when he was in school. They said, "Life evolved from the slime on the Nile River." Moses learned that growing up. Later, he edited the book of Genesis. "In the beginning, God created the heaven and the earth."

So, ultimately, in order to understand nature it may be necessary to have a deeper understanding of mathematical relationships. But the real reason is that the subject is enjoyable, and although we humans cut nature up in different ways, and we have different courses in different departments, such compartmentalization is really artificial, and we should take our intellectual pleasures where we find them.
Richard Feynman
We ourselves are part of a guild of species that lie within and without our bodies. Aboriginal peoples and the Ayurvedic practitioners of ancient India have names for such guilds, or beings made up (as we are) of two or more species forming one organism. Most of nature is composed of groups of species working interdependently ...
