This is Graff’s theory of the species and the individual. What’s important, according to Graff, is that genes live on. Again we get a notion of something like a community – here we have individuals sacrificing themselves for the species, which those individuals can never know in a direct way. Seriously: can you meet all humans? You’d have to have a lot of free time. Yet, even without meeting everyone in the species, Graff seems to think that the species makes some demands on the individual. This sounds a little bit like a community. As you can see, this book covers many different kinds of communities, from the small (the family) to the large (the species).
