Quick question: how does Toulmin’s assertion differ from Kuhn’s “modify paradigm” under the “Anomaly” step?
If you're already an expert on Kuhn, then you are closer to that answer than I am, because you only need to study up on Toulmin. ;-)
But I think you can boil it down to two words: Kuhn's "revolution", Toulmin's "evolution", the difference being Toulmin's idea is slower, steadier, less chaotic & disruptive.
My guess is a student can find good examples of both and then weigh statistically or otherwise which seems more frequent.
You would disagree?
