Final answer:
In philosophy, extension and intension relate to meanings of terms; intension, which refers to a term's properties, typically determines its extension, the set of all applicable real-world objects.
Step-by-step explanation:
The question at hand is related to the concepts of extension and intension in Philosophy, particularly in the area of logic and semantics. These terms relate to the ways in which the meaning of a word or phrase can be understood and determined. Extension refers to the set of all objects or occurrences in the real world that a term applies to, while intension refers to the internal content of a term—the necessary and sufficient conditions for the application of the term.
In essence, the intension of a term consists of the attributes, properties, or relations that the term conveys, which determines the range of objects to which the term can be correctly applied—that is, its extension. Conversely, if one knows the extension of a term, they can work out the intension by analyzing the commonalities among the objects within the extension. Therefore, intension and extension are interrelated concepts where knowing one can help to determine the other, but it is the intension that primarily determines the extension of a term.
