Abstract
This paper deals with the two kinds of commitment associated with assertive speech acts: the commitment to having justifications for the propositional content and the commitment to the truth of this content. It is argued that the former kind of commitment boils down to the monotonic commitment to the truth of the propositional content, and can be cancelled. The latter, by contrast, is non-monotonic, and is associated with all assertive speech acts, even those containing a reservation marker. These facts can be explained if one (a) endorses the ‘Direct Perception’ view, according to which every piece of communicated information goes, by default, into the hearer’s ‘belief box’; (b) defines the success of assertive speech acts in terms of the possibility to update the common ground with their propositional content.
