Single Idea 17503

[catalogued under 14. Science / B. Scientific Theories / 1. Scientific Theory]

Full Idea

Cartwright objects that the claim that theories represent what happens in actual situations is to overlook that the concepts used in them (such as 'force functions' and 'Hamiltonians') are abstract.

Gist of Idea

Theories can never represent accurately, because their components are abstract

A Reaction

I'm not convinced by this. The term 'abstract' is too loose. In a sense most words are abstract because they are universals. If I say 'that's a cat', that is a very accurate remark, despite the generality of 'cat'.
