As a moral constructivist, I think what we mean by our the way that we get to moral principles via meta ethical considerations is we start with some moral intuitions. And this is what we do as moral philosophers: We sit down and say, okay, I have these very rough incoherent, sometimes incompatible kind of messymoral intuitions. Let's work them up into a logical system that is internally consistent at the very least, okay? And then the hard part starts, that was the easy part. The hard part is you realize that your system that is nice and logical and pristine only captures some of your moral intuitions, but then other times conflicts with them.
