==Definitions==
*1a : a [[proposition]] antecedently [[supposed]] or [[proved]] as a basis of [[argument]] or [[inference]]; specifically : either of the first two propositions of a syllogism from which the [[conclusion]] is drawn
:b : something [[assumed]] or taken for granted : [[presupposition]]
*2 plural : matters previously stated; specifically : the preliminary and [[explanatory]] part of a deed or of a bill in equity
*3 plural [from its being identified in the premises of the deed]
:a : a tract of [[land]] with the buildings thereon
:b : a building or part of a building usually with its appurtenances (as grounds)
==Description==
A '''premise''' is a [[statement]] that an [[argument]] claims will induce or justify a [[conclusion]]. In other [[words]]: a premise is an [[assumption]] that something is true. In [[logic]], an argument requires a set of [[two]] declarative sentences (or "[[propositions]]") known as the ''premises'' along with another declarative sentence (or "proposition") known as the [[conclusion]]. This [[structure]] of two premises and one conclusion forms the basic [[argumentative]] [[structure]]. More [[complex]] arguments can utilize a series of rules to connect several premises to one conclusion, or to derive a number of conclusions from the original premises which then [[act]] as premises for additional conclusions. An example of this is the use of the rules of [[inference]] found within [http://en.wikipedia.org/wiki/Symbolic_logic symbolic logic].
[http://en.wikipedia.org/wiki/Aristotle Aristotle] held that any logical [[argument]] could be reduced to [[two]] ''premises'' and a [[conclusion]]. Premises are sometimes left unstated in which case they are called missing premises, for example:
:[[Socrates]] is [[mortal]], since all men are mortal.
It is [[evident]] that a tacitly [[understood]] claim is that Socrates is a man. The fully [[expressed]] reasoning is thus:
:Since all men are [[mortal]] and [[Socrates]] is a man, Socrates is mortal.
In this example, the first two independent clauses preceding the comma (namely, "all men are [[mortal]]" and "[[Socrates]] is a man") are the ''premises'', while "Socrates is mortal" is the [[conclusion]].
The [[proof]] of a [[conclusion]] depends on both the truth of the premises and the validity of the [[argument]].
