The conviction of the truth of some doctrine which is the result of a voluntary act of will. According to fideists who happen to be believers in the same doctrine, this act may be meritorious (and refusal to make it may be a fault or even a sin); according to others, it may in fact be just as sinful to ride roughshod over the deliverance of reason (itself a divine gift) when that commands us to suspend judgement. See also evidentialism.
