 Ruth Chang defines “comparativism” as the view that “comparative facts are what make a choice objectively correct; they are that in virtue of which a choice is objectively rational or what one has most or sufficient normative reason to do. So, whether you are a consequentialist, deontologist, virtue theorist, perfectionist, contractualist, etc., about the grounds of rational choice, you should be, first and foremost, I suggest, a comparativist” (2016, 213). If alternatives are incomparable, then the lack of a comparative fact precludes the possibility of justified choice.
