Doubt characterises a status in which the mind remains suspended between two contradictory propositions and unable to assent to either of them. Doubt on an emotional level is indecision between belief and disbelief. Doubt involves uncertainty, distrust or lack of sureness of an alleged fact, an action, a motive, or a decision. Doubt questions a notion of a perceived "reality", and may involve delaying or rejecting relevant action out of concerns for mistakes or faults or appropriateness. (compare paradox).
