Most interesting part (emphasis added):
My primary academic work concerns how to take into account uncertainty over different ethical viewpoints. And, as you might expect, I take quite a formal, quantitative approach, using rational choice theory to solve the problem. But some people—and I imagine you would be one of those people if I talked you through it—might accuse me of making a mistake in trying to use formal methods to accommodate my uncertainty. But then I really struggle to know—how do I take into account uncertainty over that? And I get this dizzying feeling, and I worry that life, at some fundamental level, involves a leap of faith—adopting a worldview, even though you can’t justify that worldview with respect to anything more fundamental. I’d like that not to be the case. Which is why I want to understand your view as well as I can.
