 A - Argument


Argument: In logic, a series of statements of which the last is said to be the conclusion, and the others the premisses or evidence for the conclusion.

An argument is deductively (also: logically) valid if and only if in no case where the premisses are all true the conclusion is not true. Or to put this positively: Iff in every case where the premisses are all true, the conclusion is also true.

Note that arguments may be hypothetical, namely in all those cases where not all  premisses that are used in it are known to be true.
