'Truth' may, like 'proof', be a term with only intra-theoretic applications.

Gist of Idea

'Truth' may only apply within a theory

Book Ref

'Criticism and the Growth of Knowledge', ed/tr. Lakatos,I. /Musgrave,A. [CUP 1974], p.266


A Reaction

I think we can blame Tarski (via Quine, Kuhn's teacher) for this one. I take it to be an utter failure to grasp the meaning of the word 'truth' (and sneakily substituting 'satisfaction' for it). For a start, we have to compare theories on some basis.


The 9 ideas from Thomas S. Kuhn

Kuhn came to accept that all scientists agree on a particular set of values [Kuhn, by Bird]
'Truth' may only apply within a theory [Kuhn]
In theory change, words shift their natural reference, so the theories are incommensurable [Kuhn]
Most theories are continually falsified [Kuhn, by Kitcher]
Kuhn's scientists don't aim to falsifying their paradigm, because that is what they rely on [Kuhn, by Gorham]
Switching scientific paradigms is a conversion experience [Kuhn]
Kuhn has a description theory of reference, so the reference of 'electron' changes with the descriptions [Rowlands on Kuhn]
Incommensurability assumes concepts get their meaning from within the theory [Kuhn, by Okasha]
Galileo's notions can't be 'incommensurable' if we can fully describe them [Putnam on Kuhn]
