Coextensive

In philosophy, the notion of “coextensive” (having the same scope, extent, or referring to the same objects) is expressed by several terms, often depending on the specific context and tradition.

General Philosophical Terms

Coextensive/Coextension: The primary term used across various modern philosophical and logical traditions, particularly in semantics and metaphysics, to describe two concepts, properties, or terms that apply to precisely the same set of individuals or objects.
Extensionally equivalent: This is a direct synonym used in logic and philosophy of language to indicate that two expressions have the same extension (the set of things they refer to).
Coterminous/Conterminous: Often used interchangeably with “coextensive,” implying having the same limits, edges, or boundaries in space, time, or scope.

Related Concepts in Specific Traditions/Contexts

Synonymous (in some contexts): While “synonymous” typically refers to sameness of meaning (intension), it can sometimes be used loosely to imply sameness of reference (extension) when the meanings guarantee the same application.
Materially equivalent: In formal logic, two propositions or statements are materially equivalent if they have the same truth value in all cases. This is a related formal concept, though it applies to propositions rather than the scope of terms.
Commensurate: Implies corresponding in size, degree, or extent, and can be used to describe things that are of equal scope or range.
Gongsheng (共生): In some East Asian philosophical traditions (Confucianism, Daoism, Buddhism), this notion speaks to “mutually embedded, co-existent and co-becoming entities,” which is a distinct ontological concept related to mutual dependence and shared existence, rather than just identical scope.
