Fideism (/ˈfiːdeɪɪzəm, ˈfaɪdi-/) is an epistemological theory which maintains that faith is independent of reason, or that reason and faith are hostile to each other and faith is superior at arriving at particular truths (see natural theology). The word fideism comes from fides, the Latin word for faith, and literally means 'faith-ism'.Who then will blame Christians for not being able to give reasons for their beliefs, since they profess belief in a religion which they cannot explain? They declare, when they expound it to the world, that it is foolishness, stultitiam; and then you complain because they do not prove it! If they proved it, they would not keep their word; it is through their lack of proofs that they show they are not lacking in sense.God, the origin and end of all things, can be known with certainty by the natural light of reason from the created world (cf. Rom. 1:20), that is, from the visible works of creation, as a cause from its effects, and that, therefore, his existence can also be demonstrated ...Though human reason is, strictly speaking, truly capable by its own natural power and light of attaining to a true and certain knowledge of the one personal God, who watches over and controls the world by his providence, and of the natural law written in our hearts by the Creator; yet there are many obstacles which prevent reason from the effective and fruitful use of this inborn faculty. For the truths that concern the relations between God and man wholly transcend the visible order of things, and, if they are translated into human action and influence it, they call for self-surrender and abnegation. The human mind, in its turn, is hampered in the attaining of such truths, not only by the impact of the senses and the imagination, but also by disordered appetites which are the consequences of original sin. So it happens that men in such matters easily persuade themselves that what they would not like to be true is false or at least doubtful. Fideism (/ˈfiːdeɪɪzəm, ˈfaɪdi-/) is an epistemological theory which maintains that faith is independent of reason, or that reason and faith are hostile to each other and faith is superior at arriving at particular truths (see natural theology). The word fideism comes from fides, the Latin word for faith, and literally means 'faith-ism'. Theologians and philosophers have responded in various ways to the place of faith and reason in determining the truth of metaphysical ideas, morality, and religious beliefs. A fideist is one who argues for fideism. Historically, fideism is most commonly ascribed to four philosophers: Blaise Pascal, Søren Kierkegaard, William James, and Ludwig Wittgenstein; with fideism being a label applied in a negative sense by their opponents, but which is not always supported by their own ideas and works or followers. There are a number of different forms of fideism. Alvin Plantinga defines 'fideism' as 'the 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'. The fideist therefore 'urges reliance on faith rather than reason, in matters philosophical and religious', and therefore may go on to disparage the claims of reason. The fideist seeks truth, above all: and affirms that reason cannot achieve certain kinds of truth, which must instead be accepted only by faith.
