The view defended in this paper - I call it the No-Assertion view - rejects the assumption that it is theoretically useful to single out a subset of sayings as assertions: (v) Sayings are governed by variable norms, come with variable commitments and have variable causes and effects. What philosophers have tried to capture by the term 'assertion' is largely a philosophers' invention. It fails to pick out an act-type that we engage in and it is not a category we (...) need in order to explain any significant component of our linguistic practice. Timothy Williamson (2000) defends a theory of type (i). He says that a theory of assertion has as its goal "[…] that of articulating for the first time the rules of a traditional game that we play" (p. 240). Among those who think we play the game of assertion, there's disagreement about what the rules are. Some think it's a single rule and disagree about what that rule is. Others think the rules change across contexts. According to the No-Assertion view we don’t play the assertion game. The game might exist as an abstract object, but it is not a game you need to learn and play to become a speaker of a natural language. (shrink)

According to the increasingly popular knowledge account, assertion is governed by the rule that speech acts of that kind require knowledge of their content. Timothy Williamson has argued that this knowledge rule is the constitutive rule of assertion. It is argued here that it is not the constitutive rule of assertion in any sense of the term, as it governs only some assertions rather than all of them. A (qualified) knowledge rule can in fact be derived from the traditional analysis (...) of assertion according to which assertion is the linguistic expression of belief. Because it is more informative, this analysis provides a better point of departure for defending the knowledge account than Williamson’s view according to which the knowledge rule is part of the analysis of assertion.
