Abstract

In this paper, we want to explore the connection between premises' being acceptable and their being in some sense justified. The equivalence of premise acceptability and justification seems intuitively correct. But to argue for such a connection, we need to analyze the concepts of acceptability and justification. Such an analysis also seems necessary if this equivalence is to advance our understanding of premise acceptability. Following L. J. Cohen, we may say S believes that p when S is disposed to feel it true that p, while S accepts that p when S takes that p as a premise for further deliberation or action. Reasons for belief are reasons for acceptance, and epistemological (as opposed to pragmatic) reasons for acceptance are reason for belief. Following William P. Alston, we may explicate being a justifying reason for belief through the notion of an adequate ground on which the belief is based. In turn, adequacy of ground means that the mechanism grounding the belief is reliable. Given these notions, we may define a concept of justification in terms of presumptive adequacy
