Stipulative definition

Source: Wikipedia, the free encyclopedia.

A stipulative definition is a type of

argument or discussion in a given context. When the term already exists, this definition may, but does not necessarily, contradict the dictionary (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.[1][2]

For example, in the riddle of

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".

Many holders of controversial and highly charged opinions use stipulative definitions to attach the emotional or other connotations 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.
