Evidentialism is a theory of justification according to which the justification of a conclusion depends solely on the evidence for it. Technically, though belief is typically the primary object of concern, evidentialism can be applied to doxastic attitudes generally. Formulating evidentialism in terms of the doxastic attitude of belief its most-defended form comes from Conee and Feldman: Belief, ''B'', toward proposition, ''p'', is epistemically justified for Subject, ''S'', at time, ''t'', if and only if ''B'' fits the evidence which ''S'' has at ''t''. ==Criticism== Critics of evidentialism sometimes reject the claim that a conclusion is justified only if one's evidence supports that conclusion. A typical counterexample goes like this. Suppose, for example, that Babe Ruth approaches the batter's box believing that he will hit a home run despite his current drunkenness and overall decline in performance in recent games. He realizes that, however unlikely it is that his luck will change, it would increase his chances of hitting a home run if he maintains a confident attitude. In these circumstances, critics of evidentialism argue that his belief that ''p = Babe Ruth will hit a home run'' is justified, even though his evidence does not support this belief. Evidentialists may respond to this criticism by forming a distinction between ''pragmatic'' or ''prudential justification'' and ''epistemic justification''. In Babe Ruth's case, it is pragmatically justified that he believe ''p'', but it is nevertheless epistemically unjustified: though the belief may be justified for the purpose of promoting some other goal (a successful at bat, in Ruth's case), it is not justified relative to the purely epistemic goal of having beliefs that are most likely to be true. A similar response follows the criticism that evidentialism implies all faith-based beliefs are unjustified. For example, fideism claims that evidence is irrelevant to religious beliefs and that attempts to justify religious beliefs in such a way are misguided. Superficially, fideism and evidentialism have mutually exclusive takes on religious beliefs, but evidentialists use the term "justification" in a much weaker sense than the one in which fideists most likely use it. Evidentialism merely defines the epistemic condition of a belief. Although evidentialism states that the content of the evidence does not matter, only that it constitutes valid justification towards some proposition, a skeptical criticism may be levelled at evidentialism from uncertainty theories. One's evidence may be objectively disproved at some point or it may be the case that one can never have absolute certainty of one's evidence. Given the logic of arguments concerning principles of uncertainty and randomness, skepticism towards knowledge merely becomes skepticism towards valid justification. Likewise, some say that the human mind is not naturally inclined to form beliefs based on evidence, viz. cognitive dissonance. While this may be the case, evidentialists admit, evidentialism is only meant to separate justified beliefs from unjustified beliefs. One can believe that evidentialism is true yet still maintain that the human mind is not naturally inclined to form beliefs based on evidence. He would simply have to conclude that the mind is not naturally inclined to form justified beliefs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「evidentialism」の詳細全文を読む スポンサード リンク
