This lecture discusses key ideas from the 20th century philosopher Karl Popper's article "Towards A Rational Theory Of Tradition", found in his book Conjectures and Refutations. It focuses specifically on his discussion of the various social functions that traditions play in human life, a significant part of which is to provide predictability. Popper also discusses why utopian and idealist plans to erase current conditions of society and start anew are bound to fail To support my ongoing work, go to my Patreon site - www.patreon.com/sadler If you'd like to make a direct contribution, you can do so here - www.paypal.me/ReasonIO - or at BuyMeACoffee - www.buymeacoffee.com/A4quYdWoM You can find over 3000 philosophy videos in my main YouTube channel - www.youtube.com/user/gbisadler Purchase Popper's Conjectures and Refutations - https://amzn.to/4dFvJjA
