Fideism: a view that our religious knowledge is not, and ought not to be, based upon rational or natural information, but solely on faith. The general contention of the fideists has usually been that religious knowledge is beyond the limits of a person’s rational faculties and understanding. Hence what human beings must do in order to obtain religious knowledge is first to recognize the hopelessness of accomplishing this by rational means, and then seek knowledge of God by faith alone.
