Single Idea 6162

[filed under theme 14. Science / B. Scientific Theories / 5. Commensurability ]

Full Idea

Kuhn and Feyerabend adopt a description theory of reference; the term 'electron' refers to whatever satisfies the descriptions associated with electrons, and since these descriptions vary between theories, so too must the reference.

Gist of Idea

Kuhn has a description theory of reference, so the reference of 'electron' changes with the descriptions

A Reaction

This is a key idea in modern philosophy, showing why all of reality and science were at stake when Kripke and others introduced a causal theory of reference. All the current debates about externalism and essentialism grow from this problem.

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]
