Single Idea 19007
[filed under theme 14. Science / B. Scientific Theories / 2. Aim of Science
]
Full Idea
A physical theory need not be true to be good, Field has argued, and I agree. All we ask of it truth-wise is that its physical implications should be true, or, in my version, that it should be true about the physical.
Gist of Idea
A theory need not be true to be good; it should just be true about its physical aspects

A Reaction
Yablo is, of course, writing a book here about the concept of 'about'. This seems persuasive. The internal terminology of the theory isn't committed to anything - it is only at its physical periphery (Quine) that the ontology matters.
