In a series of papers, Sperber provides the following analysis of the
phenomenon of ill-understood belief (or 'quasi-belief', as I call it):
(i) the quasi-believer has a validating meta-belief, to the effect th
at a certain representation is true; yet (ii) that representation does
not give rise to a plain belief, because it is 'semi-propositional'.
In this paper I discuss several aspects of this treatment. Ln particul
ar, I deny that the representation accepted by the quasi-believer is s
emantically indeterminate, and I reject Sperber's claim that quasi-bel
ief is a credal attitude distinct from plain belief.
