My take from this book is that:

- scientific knowledge is embedded in some intellectual ether made of underlying hypotheses often not explicitly stated called paradigms

- paradigms follow a Darwinian evolutionary process, i.e. better paradigms evolve out of not-so-good previous paradigms

- paradigm replacements start with an epistemological crisis , i.e. facts that the current paradigms don't explain well enough.

Hope it helps !
