[filed under theme 14. Science / B. Scientific Theories / 2. Aim of Science ]

Full Idea

Scientists are not trying to maximise some formal property of 'simplicity'; they are trying to maximise truth.

Gist of Idea

Science aims at truth, not at 'simplicity'

Source

Hilary Putnam (Explanation and Reference [1973], III B)

Book Ref

Putnam,Hilary: 'Mind Language and Reality: Papers vol 2' [CUP 1975], p.212


A Reaction

This seems to be aimed at the Mill-Ramsey-Lewis account of laws of nature, as the simplest axioms of experience. I'm with Putnam (as he was at this date).


The 6 ideas from 'Explanation and Reference'

Putnam bases essences on 'same kind', but same kinds may not share properties [Mackie,P on Putnam]
Express natural kinds as a posteriori predicate connections, not as singular terms [Putnam, by Mackie,P]
Using proper names properly doesn't involve necessary and sufficient conditions [Putnam]
Natural kind stereotypes are 'strong' (obvious, like tiger) or 'weak' (obscure, like molybdenum) [Putnam]
I now think reference by the tests of experts is a special case of being causally connected [Putnam]
Science aims at truth, not at 'simplicity' [Putnam]
