 Models of faith as knowledge may be thought lacking because they admit no actional component in faith itself. Faith seems essentially to involve some kind of active venture in commitment and trust, even if talk of a ‘leap of faith’ may not be wholly apt. Many have held that faith ventures beyond what is ordinarily known or justifiably held true, in the sense that faith involves accepting what cannot be established as true through the proper exercise of our naturally endowed human cognitive faculties. As Kant famously reports, in the Preface to the Second Edition of his Critique of Pure Reason: ‘I have … found it necessary to deny knowledge, in order to make room for faith’ (Kant 1787 [1933, 29]). Theist philosophers do, however, typically defend the claim that faith is not ‘contrary to reason’. On models of faith that take a cognitive component as central, and construe faith’s object as propositional, reasonable faith therefore seems subject to a general evidentialist principle—‘a wise man ... proportions his belief to the evidence’, as Hume puts it (Hume 1748 [2007], “Of Miracles”, 80). And W. K. Clifford elevates evidentialism to the status of an absolute moral requirement, affirming that ‘it is wrong always, everywhere, and for anyone to believe anything upon insufficient evidence’ (Clifford 1877 [1999, 77]. Faith’s venturesomeness may thus seem in tension with its reasonableness, and models of faith differ in the way they negotiate this tension in response to evidentialist challenges. Another way to classify models of faith, then, is in terms of their associated epistemology—and, in particular, whether and according to what norms of ‘evidential support’, they accept that faith’s cognitive component needs to meet a requirement to be grounded on available evidence.
