How do you define "utility" in a way that it is intrinsically
rational? "Utility" in the context of natural selection for instance
is "stay alive enough time to reproduce". But does that make this
utility definition intrinsically "rational" by any means?

As I mentioned earlier, I find it difficult to see rationality by
itself as a source of supergoals (or Utility()...).
