 Alvin Plantinga has noted that fideism can be defined as an “exclusive or basic reliance upon faith alone, accompanied by a consequent disparagement of reason and utilized especially in the pursuit of philosophical or religious truth” (87). Correspondingly, Plantinga writes, a fideist is someone who “urges reliance on faith rather than reason, in matters philosophical and religious” and who “may go on to disparage and denigrate reason” (87). Notice, first, that what the fideist seeks, according to this account, is truth. Fideism claims that truths of a certain kind can be grasped only by foregoing rational inquiry and relying solely on faith. Insofar as fideism insists that knowledge of these truths is possible, it must be distinguished from various forms of skepticism with which it otherwise shares certain common features. Notice too that this definition is largely formal; the plausibility of fideism as a philosophical doctrine and the proper extension of the term will therefore depend on the content given to the terms “faith” and “reason.”
