Is has utility toward ought

Four years ago, Will Wilkinson, stated:

… So, I will powerfully counter-assert: a theory of human nature is NOT supposed to be normative. Take that Richard Rorty! A theory of human nature, or at least a theory of homo sapiens is supposed to tell us what we are like and how we got to be that way. Such theories need tell us no more about what we ought to be like than the theory of the big bang need tell us what the universe ought to be.

Science can tell us a lot about the space of possibility, however. And because ‘ought’ implies ‘can’, there is a straightforward link from the descriptive to the normative. Because a theory of human nature can tell us a lot about what we can’t do, and what won’t work, we can learn a lot about what we shouldn’t do.

I would go further than Will in bowing before the alter of science, but will elaborate on that later….
