that the sentences
(1) Pierre believes that London is pretty
and
(2) Pierre believes that London is not pretty
both truly describe Kripke’s well‐known situation involving puzzling

to which Pierre believes either the proposition (actually) expressed
by
(3) London is pretty
or the proposition (actually) expressed by
(4) London is not pretty.
These claims, Lewis suggests, provide a starting point from which a
correct resolution of Kripke’s puzzles about belief ([3]) can be
developed.
At the end of his paper ([4], p. 414‐7), Lewis considers and replies
to a number of potential objections to his position. According to one of
these, Lewis’s contentions regarding (1)‐(4) cannot all be true
because ‘believes that’ and ‘believes the proposition that’ are
synonymous. Although the objection Lewis considers is unsound and
his response to it correct, a minor variant of that objection provides
significant reason to be skeptical of his contentions. This variant,
moreover, is not persuasively addressed by anything either Lewis or
any other well‐known defender of this sort of view (such as Stalnaker
[8]) has had to say on the matter. All of this is relevant, moreover, not

only when it comes to assessing Lewis’s contentions regarding (1)‐
(4), but also when it comes to drawing lessons from certain standard
objections to the view that the propositional objects of belief and
assertion are sets of metaphysically possible worlds.
