Doubt is a mental state in which the mind remains suspended between two or more contradictory propositions, unable to assent to any of them. Doubt on an emotional level is indecision between belief and disbelief. It may involve uncertainty, distrust or lack of conviction on certain facts, actions, motives, or decisions. Doubt can result in delaying or rejecting relevant action out of concern for mistakes or missed opportunities.
Doubt is the negation of belief. It is the condition of not having reached a conclusion for or against any proposition. While disbelief is the positive conclusion of the falsity of a proposition, doubt is a suspension of judgement, a state of being unconvinced. It results in inaction, the failure to commit for or against.
Doubt is the essence of a mature faith.
