32-477: A group , is the underlying set of the object. The extension of a set is the set itself. That a set can capture the notion of the extension of anything is the idea behind the axiom of extensionality in axiomatic set theory . This kind of extension is used so constantly in contemporary mathematics based on set theory that it can be called an implicit assumption. A typical effort in mathematics evolves out of an observed mathematical object requiring description,

In computer science , some database textbooks use the term 'intension' to refer to the schema of a database, and 'extension' to refer to particular instances of a database. There is an ongoing controversy in metaphysics about whether or not there are, in addition to actual, existing things, non-actual or nonexistent things. If there are—if, for instance, there are possible but non-actual dogs (dogs of some non-actual but possible species, perhaps) or nonexistent beings (like Sherlock Holmes, perhaps)—then these things might also figure in

Some concepts and expressions are such that they don't apply to objects individually, but rather serve to relate objects to objects. For example, the words "before" and "after" do not apply to objects individually—it makes no sense to say "Jim is before" or "Jim is after"—but to one thing in relation to another, as in "The wedding
