 Evidentialism is the view that for a person to be justified in some belief, that person must have some awareness of the evidence for the belief. This is usually articulated as a person’s belief being justified given the total evidence available to the person. On this view, the belief in question must not be undermined (or defeated) by other, evident beliefs held by the person. Moreover, evidentialists often contend that the degree of confidence in a belief should be proportional to the evidence. Evidentialism has been defended by representatives of all the different viewpoints in philosophy of religion: theism, atheism, advocates of non-theistic models of God, agnostics. Evidentialists have differed in terms of their accounts of evidence (what weight might be given to phenomenology?) and the relationship between evident beliefs (must beliefs either be foundational or basic or entailed by such foundational beliefs?) Probably the most well known evidentialist in the field of philosophy of religion who advocates for theism is Richard Swinburne (1934–).
