Coherence and Knowability.

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view explains what is wrong with certain akratic doxastic states. In this paper, I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment, and credence. Finally, it is suggested that this picture can be generalized to the realm of practical rationality as well. [ABSTRACT FROM AUTHOR]
