My reading of Feynman is a little different: I think the point is that philosophy of science has only analysed history so far and has never by itself brought about a change in the way science is done.<p>This is not to say that the philosophy is useless or that it will never influence science in the future - Feynman is just stating how things have been.<p>Put another way, I simply don&#x27;t see philosophy of science as it is helping someone do better science. I would be very interested if this were false.
