expressivist

Pertaining to or advocating expressivism, the doctrine that the primary function of moral sentences and sensation sentences (like "I am in pain") is to express an evaluative attitude, rather than stating a fact

Since cognitivism is already a commitment of SEN, I see no harm in assuming it so long as we keep in mind that one possible lesson of MTE is that the content of moral predicates is [primarily] non-cognitive or expressivist.
