Editing Stipulative definition

{{Short description|Definition for the purpose of discussion}}
A '''stipulative definition''' is a type of [[definition]] in which a new or currently existing term is given a new specific meaning for the purposes of [[Logical argument|argument]] or discussion in a given context. When the term already exists, this definition may, but does not necessarily, contradict the [[dictionary]] ([[lexical definition|lexical]]) definition of the term. Because of this, a stipulative definition cannot be "correct" or "incorrect"; it can only differ from other definitions, but it can be useful for its intended purpose.<ref>{{cite web |url=http://atheism.about.com/od/logicalarguments/a/def_stipulative.htm |title=Stipulative Definitions |last=Cline |first=Austin |work=Atheism.about.com |publisher=[[About.com]] |url-status=live |archive-url=https://web.archive.org/web/20120104021753/http://atheism.about.com/od/logicalarguments/a/def_stipulative.htm |archive-date=2012-01-04 |access-date=2017-01-10 }}</ref><ref name=ConciseIntro>Hurey, Patrick J.

For example, in the riddle of [[Inductive reasoning|induction]] by [[Nelson Goodman]], "[[Grue and Bleen|grue]]" was ''stipulated'' to be "a property of an object that makes it appear green if observed before some future time ''t'', and blue if observed afterward". "Grue" has no meaning in standard English; therefore, Goodman created the new term and gave it a ''stipulative definition''.

==On stipulative definitions==
Stipulative definitions of existing terms are useful in making theoretical arguments, or stating specific cases. For example:
*Suppose we say that to love someone is to be willing to die for that person.
*Take "human" to mean any member of the species ''Homo sapiens''.
*For the purposes of argument, we will define a "student" to be "a person under 18 enrolled in a local school".

Some of these are also [[precising definition]]s, a subtype of stipulative definition that may not contradict but only extend the [[lexical definition]] of a term. [[Theoretical definition]]s, used extensively in [[science]] and philosophy, are similar in some ways to stipulative definitions (although theoretical definitions are somewhat normative,{{Elaborate|date=June 2024}} more like [[persuasive definitions]]).<ref name=ConciseIntro/>

Many holders of controversial and highly charged opinions use stipulative definitions to attach the emotional or other [[connotation]]s of a word to the meaning they would like to give it; for example, defining "murder" as "the killing of any living thing for any reason". The other side of such an argument is likely to use a different stipulative definition for the same term: "the unlawful killing of a human being with malice aforethought" or "the premeditated killing of a human being". The lexical definition in such a case is likely to fall somewhere in between.

When a stipulative definition is confused with a lexical definition within an argument there is a risk of [[equivocation]].
