Traditional epistemology embraces an inferential concept of justification: a belief is justified just in case it can be reasonably inferred from other beliefs. Inferential justification immediately incurs the problem of infinite regress, since the justifying beliefs themselves are in need of further justification. In this paper I will try to explicate a new idea of inferential justification that does not regress indefinitely. I will begin by analyzing the traditional notion of inferential justification as involving three principles, namely narrow inferentialism, formalism, and linear regress justification. All three principles are critically examined, and in their place, three new ones are proposed: broad inferentialism, materialism, and interactive justification. The principles constitute a new inferential approach which admits of no infinite regress.
