> (though his protest that in 1945 it was widely denied that there is any knowledge but scientific knowledge seems deeply silly per se and exactly the kind of thing you often see from people trying to push a “rebel” image for marketing reasons… Look up "logical positivism" as a philosophical system. It became the dominant academic philosophy for a while (including around 1945). It asserted almost exactly that - that there was no knowledge apart from scientific knowledge (although I believe it did accept direct sensory input as knowledge, and also the operations of pure logic).
