Single Idea 19179

[filed under theme 2. Reason / D. Definition / 1. Definitions ]

Full Idea

We must specify the words or concepts which we wish to use in defining the notion of truth; and we must also give the formal rules to which the definition should conform. More generally, we must describe the formal structure of the language.

Gist of Idea

For a definition we need the words or concepts used, the rules, and the structure of the language

A Reaction

This, of course, is a highly formal view of how definition should be achieved, offered in anticipation of one of the most famous definitions in logic (of truth, by Tarski). Normally we assume English and classical logic.

11215 Notable definitions have been of piety (Plato), God (Anselm), number (Frege), and truth (Tarski) [Gupta]
11223 Definitions usually have a term, a 'definiendum' containing the term, and a defining 'definiens' [Gupta]
23744 Defining a set of things by paradigms doesn't pin them down enough [Smith,M]
14100 Figuring in the definition of a thing doesn't make it a part of that thing [Rosen]
