Thanks Patricia. I think I mostly agree with you. UFE is probably better reconciled as principle-based. Patton seems to do that in his principles book. On the second point, I agree the distinction is deliberately crude. My aim was to illustrate that there's some degree of path dependence which comes with axiological, ontological or epistemic positions. It wasn't my intention to suggest realist and constructivist are the same (they obviously aren't), but rather that realists/critical realists and constructivists seem to have a certain reflexivity on truth and reality that is largely absent in a particular cadre of post-positivists. If I had more space (i.e., if it were a paper not a blog), I would have elaborated further on the nuance.
