  Some non-cognitivists have accepted these theses in their strongest form – moral sentences in no way predicate properties, are apt for truth or falsity, or express beliefs. But most current non-cognitivists accept these negative claims only in a somewhat weakened form. For example many non-cognitivists hold that moral judgments’ primary function is not to express beliefs, though they may express them in a secondary way. Others deny that their contents are true or false in any robust sense but not that they can be true or false in a deflationary sense according to which there is no substantial property separating true and false sentences.
