 There may be no such topic as the logic of propositional attitudes: it may be doubted whether ‘Mary wants to meet a man who has read Proust and a man who has read Gide’ logically entails ‘Mary wants to meet a man who has read Proust’. Even if standing in the wanting-to-be-true attitude to I meet a man who has read Proust and a man who has read Gide somehow necessitates standing in the wanting-to-be-true attitude to I meet a man who has read Proust, the necessitation appears to be more psychological than logical. On the other hand, what we might call ‘objectual attitudes’, the non-propositional attitudes ascribed by intensional transitives, seem to have a logic (for a compendium of examples, see Richard 2000, 105–7): ‘Mary seeks a man who has read Proust and a man who has read Gide’ does seem to entail ‘Mary seeks a man who has read Proust’.
