    • n fact Anything done; an act; a deed; a feat.
    • n fact A real state of things, as distinguished from a statement or belief; that in the real world agreement or disagreement with which makes a proposition true or false; a real inherence of an attribute in a substance, corresponding to the relation between the predicate and the subject of a proposition. By a few writers things in the concrete and the universe in its entirety are spoken of as facts; but according to the almost universal acceptation, a fact is not the whole concrete reality in any case, but an abstract element of the reality. Thus, Julius Cæsar is not called a fact; but that Julius Cæsar invaded Britain is said to have been a fact, or to be a fact. To this extent, the use of the word fact implies the reality of abstractions. With the majority of writers, also, a fact, or single fact, relates only to an individual thing or individual set of things. Thus, that Brutus killed Cæsar is said to have been a fact; but that all men are mortal is not called a fact, but a collection of facts. By fact is also often meant a true statement, a truth, or truth in general; but this seems to be a mere inexactness of language, and in many passages any attempt to distinguish between the meanings on the supposition that fact means a true statement, and on the supposition that it means the real relation signified by a true statement would be empty subtlety. Fact is often used as correlative to theory, to denote that which is certain or well settled—the phenomena which the theory colligates and harmonizes. Fact, as being special, is sometimes opposed to truth, as being universal; and in such cases there is an implication that facts are minute matters ascertained by research, and often inferior in their importance for the formation of general opinions, or for the general description of phenomena, to other matters which are of familiar experience.
    • n fact In law, an actual or alleged physical or mental event or existence, as distinguished from a legal effect or consequence: as in the phrases matter of fact, question of fact, the facts of the case, as distinguished from matter of law, question of law, the law of the case. Thus, whether certain words were spoken is a question of fact; whether, if spoken, they constituted a binding promise, is usually a question of law.
