Contingency (philosophy) - Wikipedia, the free encyclopedia
of propositions that are neither true under every possible valuation (i.e. tautologies) nor false under every possible valuation (i.e. contradictions)
A contingent proposition is neither necessarily true nor necessarily false
truth value of the proposition is contingent upon the truth values of the sentences which comprise it
Contingent propositions depend on the facts, whereas analytic propositions are true without regard to any facts about which they speak
Tautological propositions, which must be true, no matter what the circumstances are or could be
Contradictions which must necessarily be untrue, no matter what the circumstances are or could be
Possible propositions, which are true or could have been true given certain circumstances
