Episode 107: Was Popper a Fideist?
from The Theory of Anything · host Bruce Nielson and Peter Johansen
Here we discuss fidesim and critical rationalism. Fideism has many definitions, but at least how we are thinking of it, it is the idea that something like faith has validity in the process of moving closer to truth through reason.Our starting point is a paper written by prominent Popperian Joseph Agassi about how William Bartley, another critical rationalist philosopher closely associated with Popper, had a falling out with Popper after he accused Popper of being a fideist, which Popper apparently did not consider a compliment. But was Bartley perhaps correct?Note: we decided to cover this paper before we even realized it was about fideism which -- by pure dumb luck -- happened to be part of the topic of our last episode (#106: Karl Popper and God) where Bruce declared himself a Fideist. As such, episode #106 is not required listening, but you might find Popper's views on God and his views on epistemological fideism an interestingly interplay.Support us on Patreon
