 Partly in  response to this move, minimalist defenders of the collapse argument have responded by moving to the notion of minimal belief.  They can say that a state of mind is a belief and hence cognitive if and only if it is one expressed by a sentence with truth conditions.  Since minimalism secures minimal truth conditions, indicative moral sentences have truth conditions and the states they express are beliefs. If the argument works, quasi-realist non-cognitivism would undermine its own right to employ both of the negative constitutive claims distinctive of non-cognitivism.
