This paper discusses the view about the problem of self-knowledge that Crispin Wright has proposed in a series of his papers, which is closely related to Wittgenstein's 'rule-following' consideration. Based on his insight that intentions are not independent of subject's judgments about them (judgment dependence of intention, JDI), Wright offered the so-called 'extension-determination approach' to intentions (EDA). Though EDA is original and effective as an answer to the problem of self-knowledge, it intrinsically has a serious problem of infinite regress. This paper aims to suggest an alternative view that follows his basic insight (JDI) but that can avoid this serious problem.
