  So, in addition to their analyses of unembedded predication, non-cognitivists owe us an account of the meanings of more complex sentences or judgments such as these. Of course there are some desiderata we would like an adequate account to fulfill.  (1) One is compositionality; the meaning of a complex sentence embedding a moral claim should be a function of the meaning of its parts so as to explain the ease with which speakers can understand novel normative sentences. (2) Another is that it should preserve and explain the logical relations between moral judgements and other judgements which embed them, at least for central cases. And (3), we want the account not to require implausible verdicts in attributing attitudes to people who use the sentences. For example, if a non-cognitivist says the meaning of ‘Lying is wrong’ is to express disfavor towards lying, that does not yet provide a good explanation of the attitude expressed by the very same words used in many embedded contexts. When those words occur in the antecedent of a conditional, or when a person says, ‘I wonder if lying is wrong’ they they are typically not being used to express such disapproval. The point here is not that these desiderata cannot be satisfied. Leading contemporary non-cognitivists have all tried to provide accounts. As it turns out, the task is difficult and generates much controversy.
