condition

+2	1. in logic, a stipulation or provision, that needs to be satisfied; also, something that must exist or be the case or happen in order for something else to do so (as in the will to live is a condition for survival). In logic, a sentence or proposition of the form If A then B (in symbols, A B) is called a conditional (sentence or proposition). Similarly, Whenever A then B (in symbols, (x) (A(x) B(x)) may be called a general conditional. In such uses, conditional is a synonym for hypothetical and is opposed to categorical. Closely related in meaning are the common and useful expressions sufficient condition and necessary condition. If some instance of a property P is always accompanied by a corresponding instance of some other property Q, but not necessarily vice versa, then P is said to be a sufficient condition for Q and, equivalently, Q is said to be a necessary condition for P. Thus, a severed spinal column is a sufficient, but not a necessary, condition for death; while lack of consciousness is a necessary, but not a sufficient, condition for death. In any case in which P is both a necessary and a sufficient condition for Q, the latter is also a necessary and sufficient condition for the former, each being regularly accompanied by the other. The terminology is also applicable to logical or mathematical or other nontemporal properties; thus, it is proper to speak of a necessary condition for the solution of an equation or a sufficient condition for the validity of a syllogism.
