A moment's thought shows that man's feeling of isolation has no foundation, biologically or sociologically. We grow out of the Universe, we are an expression of it. The iron in our blood comes from the high temperature fusion of stars. We constantly interact with our environment. The force of gravity keeps our feet upon the earth and has a vital effect upon our metabolism. The air we breathe comes form the seas and the leaves, and the sun allows the process to take place. Society gives us all that makes us human our culture, our symbols, our concepts and our values. Without society, the notion of the individual would have no meaning.
