The purpose of the present chapter is to survey the work on epistemic norms of action, practical deliberation and assertion and to consider how these norms are interrelated. On a more constructive note, we will argue that if there are important similarities between the epistemic norms of action and assertion, it has important ramifications for the debates over speech acts and harm. Thus, we hope that the chapter will indicate how thinking about assertions as a speech act can benefit from (...) a broader action theoretic setting. We will proceed as follows. In Section 2, we provide a survey of epistemic norms of action and practical deliberation. In Section 3, we turn to the epistemic norms of assertion. In Section 4, we consider arguments for and against commonality of the epistemic norms of actions, practical deliberation and assertion. In Section 5, we discuss some of the ramifications of the debates over epistemic norms of assertion such as whether they may be extended to other linguistic phenomena such as Gricean implicature. In Section 6, we consider the consequences of the debate about the epistemic norms of action and practical deliberation for debates about speech and harm. (shrink)
