"What we have in human nature is our inheritance from a prehistoric past going back millions of years. We do have strong predispositions—you can call them instincts—that become dangerous in modern society. So, what we should do is conduct the best research we can, in biology and the social sciences, and find out what it is to be human. And then recognize that these are particular flaws in our nature in a modern techno-scientific world, and work with that knowledge to pull us on through. This is not unlike, say, trying to find the basis for genetic disease, to look for things that make people sick because of mutated genes or pathogens, to find out what causes sickness. Would you then say this sickness is the way things should be, because “is” is “ought”? That is crazy. But the naturalistic fallacy is equally crazy in terms of human nature."
