Single Idea 20389

[catalogued under 2. Reason / D. Definition / 1. Definitions]

Full Idea

If we specify the 'necessary' conditions that are 'sufficient' for something's being an X, that is a combination of conditions such that all and only Xs meet them, which is the hallmark of a definition of X-hood.

Gist of Idea

A definition of a thing gives all the requirements which add up to a guarantee of it

A Reaction

There are, of course, many other ways to define something, as shown in the 2.D Reason | Definition section of this database. This nicely summarises the classical view.
