Disbelief \Dis*be*lief"\, n. The act of disbelieving;; a state of the mind in which one is fully persuaded that an opinion, assertion, or doctrine is not true; refusal of assent, credit, or credence; denial of belief. [1913 Webster] Our belief or disbelief of a thing does not alter the nature of the thing. --Tillotson. [1913 Webster] No sadder proof can be given by a man of his own littleness that disbelief in great men. --Carlyle. Syn: Distrust; unbelief; incredulity; doubt; skepticism. -- Disbelief, Unbelief. Unbelief is a mere failure to admit; disbelief is a positive rejection. One may be an unbeliever in Christianity from ignorance or want of inquiry; a unbeliever has the proofs before him, and incurs the guilt of setting them aside. Unbelief is usually open to conviction; disbelief is already convinced as to the falsity of that which it rejects. Men often tell a story in such a manner that we regard everything they say with unbelief. Familiarity with the worst parts of human nature often leads us into a disbelief in many good qualities which really exist among men. [1913 Webster]
