Much philosophical effort has been exerted over problems having to do with the correct analysis and application of the concept of epistemic justification. While I do not wish to dispute the central place of this problem in contemporary epistemology, it seems to me that there is a general neglect of the belief condition for knowledge. In this paper I offer an analysis of ‘degrees of belief’ in terms of a quality I label ‘conviction’, go on to argue that one requires more conviction in a proposition in order to know it than to merely believe it, and conclude by suggesting that some current epistemological issues admit of new insight when we begin taking conviction seriously.
