I'm having trouble understanding this comment. You seem to be grasping at one of the central points the author is raising, but you've phrased your comment as if what you've said is in opposition. Nature doesn't care about divisions, but our ways of communicating and sharing scientific knowledge are shaped by them - often to our detriment.

I suppose the issue is that the text could have been named 'The Structure of Academic Revolutions' which might be closer to its intent and meaning?

Nevertheless the natural world, the object of scientific study, should remain the focus of attention, and the fundamental approaches - observation, experiment, theoretical construction - haven't really changed at all since the concept was invented.
