which one crumbled? lol. I know. I know. But then again, david, why would you expect otherwise? Differing paradigms cannot be squeezed into each other. That’s what makes them different. What happens in the real world, and Kuhn’s book so brilliantly points this out, is that the new paradigm is mocked, ridiculed, and recused until it eventually overwhelms the previous one. New paradigms don’t blend into each other. They replace each other. But hey, at least you checked into it. Kudos for you.
