A Riddle and a Buried Assumption
The negative findings of the last two chapters ought to puzzle anyone who has not distinguished more than one version of the practicality argument. For it would seem that this argument in its only fully extant form in contemporary literature – the form in which it is claimed to drive us towards non-cognitivism – hardly warrants its formidable reputation. But (unless we posit another version) this must leave it unaccountable how certain recent writers have managed to deploy the argument, or at least its second premiss, with such apparently devastating effect against their opponents. I have chiefly in mind here Bernard Williams.
