[catalogued under 7. Existence / D. Theories of Reality / 1. Realism]

Full Idea

What makes the metaphysical realist a 'metaphysical' realist is his belief that there is somewhere 'one true theory' (two theories which are true and complete descriptions of the world would be mere notational variants of each other).

Gist of Idea

Metaphysical realism is committed to there being one ultimate true theory

A Reaction

This is wrong!!!!! Commitment to one reality doesn't imply that only one comprehensive theory is possible. Theory-making (at least in any human language, or in mathematics) is an inherently limited activity.
