#50 – The Retreat to Commitment by W.W. Bartley, Appendix 4 – Part 3
This episode of the Popperian Podcast is part of a series on William Bartley and his book The Retreat to Commitment. ** John Post’s description of the alleged paradox within pancritical rationalism, as presented by William Bartley on page 224 of The Retreat to Commitment: Since (B) is implied by (A), any criticism of (B) will constitute a criticism of (A), and thus show that (A) is open to criticism. Assuming that a criticism of (B) argues that (B) is false, we may argue: if (B) is false, then (A) is false; but an argument showing (A) to be false (and thus criticizing it) shows (B) to be true. Thus, if (B) is false, then (B) is true. Any attempt to criticize (B) demonstrates (B); thus (B) is uncriticizable, and (A) is false. *** Retreat to Commitment Retreat to Commitment by Bartley - AbeBooks and Retreat to Commitment: Bartley, III: 9780812691276: Amazon.com: Books Support via Patreon – https://www.patreon.com/jedleahenry Support via PayPal – https://www.paypal.me/jrleahenry Website – The Popperian Podcast — Jed Lea-Henry Libsyn – The Popperian Podcast (libsyn.com) Youtube – The Popperian Podcast - YouTube Twitter – https://twitter.com/jedleahenry RSS - https://popperian-podcast.libsyn.com/rss *** Underlying artwork by Arturo Espinosa
