To talk of ‘ought-facts’ is apt insofar as any manifestation of an Ought seems to be connected with some kind of objectivity. And if facts are simply ‘true thoughts’, there is nothing strange about saying, for example, ‘It is a fact that, under circumstances c, x ought to be the case’. Taking ought-facts to be facts sui generis does not entail, however, that they can be reduced to natural facts, or brute social facts (or some other kind of non-normative facts). On the contrary, the case might be argued that natural facts depend for their objectivity on irreducible normativity, namely, obligations to think in a certain way.
