In his later writings (from 1969 on), Thomas Kuhn stopped talking about "paradigms" or "disciplinary matrixes" and started talking about "theories" instead. Some Kuhnians say that from then on, when he wrote "theory", he meant "paradigm"/"disciplinary matrix". Did Kuhn say that he was doing this? If so, where in his writings?
See SST (1962), page 10:
By choosing it [the term "paradigm"] I mean to suggest that some accepted examples of actual scientific practice - examples which include law, theory, application, and instrumentation together - provide models from which spring particular coherent traditions of scientific research.
Thus, the original meaning of "paradigm" includes theories.
And see also Second Thoughts on Paradigms (1974), reprinted into The Essential Tension: Selected Studies in Scientific Tradition and Change (University Of Chicago Press (1977), page 316, where the term paradigm has been "redefined" to name
"shared [by the scientific community] examples of successful practice. [...] Those examples were its paradigms."
For the source of so-called "linguistic turn" in Kuhn's philosophy:
In the 1980s Kuhn employed the concept of lexicon and its structure as a new tool for explicating incommensurability.[...] As a consequence of the “linguistic turn”, several significant changes affect Kuhn’s philosophy, each of which is connected to the notion of taxonomic change. First of all, the terms “paradigm” and “disciplinary matrix” disappear: Kuhn preferred to employ simply the term “theory”. It is not simply a terminological change, since while the notion of paradigm is too wide to allow for talking about the lexicon of a paradigm, it is perfectly meaningful to speak about the lexicon of a theory.
Thus, according to this reading, it is still true that the notion of paradigm is wider than that of theory.
The main source is Commensurability, Comparability, Communicability (1983), reprinted as Chapter Two of The Road Since Structure: Philosophical Essays, 1970-1993 (The Univ.of Chicago Press, 2000).
Here Kuhn says [page57]: "the members of a speech community agree on a number of standard examples (paradigms)".
See also the following chapter of the same book, reprinting: Possibly Worlds in History of Science (1986).
In both chapters, the discussion is about the translations between different (and competing) scientific theories, a topic that was already present in SST.
