DescriptionIn this dissertation I take up two challenges for any final or ultimate normative theory: that of explaining the apparent conflict between different normative domains, and that of accommodating all subjective normative facts. I propose a framework for a normative theory that explains how conflict between normative domains could be consistent, and I describe a way to build all-things-considered normative concepts that take all domains into consideration. However, I argue that the second challenge is more serious: that no normative theory could accommodate all subjective normative facts. If I’m right, where does this leave us? I propose a way to extend the solution to the first challenge to accommodate a very large number of subjective normative facts, and I suggest that we think of this theory as an ‘open-ended’ one that’s meant to be extended indefinitely.
