 Moore’s problem is to explain what is odd about declarative utterances such as (M). This explanation needs to encompass both readings of (M): ‘\(p \amp B{\sim}p\)’ and ‘\(p \amp{\sim}Bp\)’. (This scope ambiguity is exploited by a popular joke: René Descartes sits in a bar, having a drink. The bartender asks him if he would care for another. “I think not,” he says, and disappears. The joke is commonly criticized as fallacious. But it is not given Descartes’ belief that he is essentially a thinking being.)
