EXCERPT (Nigel Warburton): The American physicist Richard Feynman is often quoted as saying: ‘You can recognise truth by its beauty and simplicity.’ [...] Feynman was unquestionably one of the outstanding physicists of the 20th century. [...] In the area of philosophy of science, though, like many physicists of his and the subsequent generation (and unlike those belonging to the previous one, including Albert Einstein and Niels Bohr), Feynman didn’t really shine – to put it mildly...
[...] The problem is that it’s difficult to defend the notion that the truth is recognisable by its beauty and simplicity, and it’s an idea that has contributed to getting fundamental physics into its current mess; for more on the latter topic, check out The Trouble with Physics (2006) by Lee Smolin, or Farewell to Reality (2013) by Jim Baggott, or subscribe to Peter Woit’s blog....
[...] But as the German theoretical physicist Sabine Hossenfelder has pointed out (also in Aeon), there is absolutely no reason to think that simplicity and beauty are reliable guides to physical reality. She is right for a number of reasons. [...] To begin with, the history of physics (alas, seldom studied by physicists) clearly shows that many simple theories have had to be abandoned in favour of more complex and ‘ugly’ ones. [...] And of course, beauty is, notoriously, in the eye of the beholder. What struck Feynman as beautiful might not be beautiful to other physicists or mathematicians. Beauty is a human value, not something out there in the cosmos. Biologists here know better...
[...] The moral of the story is that physicists should leave philosophy of science to the pros, and stick to what they know best. Better yet: this is an area where fruitful interdisciplinary dialogue is not just a possibility, but arguably a necessity. As Einstein wrote in a letter to his fellow physicist Robert Thornton in 1944:
"I fully agree with you about the significance and educational value of methodology as well as history and philosophy of science. So many people today – and even professional scientists – seem to me like someone who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is – in my opinion – the mark of distinction between a mere artisan or specialist and a real seeker after truth. (MORE - details)
