 Evidentialism has been challenged on many grounds. Some argue that it is too stringent; we have many evident beliefs that we would be at a loss to successfully justify. Instead of evidentialism, some philosophers adopt a form of reliabilism, according to which a person may be justified in a belief so long as the belief is produced by a reliable means, whether or not the person is aware of evidence that justifies the belief. Two movements in philosophy of religion develop positions that are not in line with the traditional evidential tradition: reformed epistemology and volitional epistemology.
