ABSTRACT
In this chapter, the author explains some of the central themes in modal epistemology such as non-accidental warrants, modal identity criteria for warrants internal vs. external warrants; sensitivity to epistemic settings. In order to avoid the attack Edmund Gettier launched against the classical tripartite definition that it seems reasonable to focus attention on modalised theories of knowledge. The basic idea behind theory of knowledge is that mere justification is not appropriate for gaining knowledge. Gettier's reminder that knowledge cannot be identified with justified true belief kicked off a heated debate about what knowledge really is, and, further, whether knowledge allows for conceptual analysis at all. The author suggests that knowledge is related to belief, justification and truth, and regard the challenge as to clarify and improve on these ingredients' exact nature and internal association. The author also presents an overview of this book.
