In this episode, Bruce explores his extended conversation with philosopher and inductivist Kieren, focusing on Kieren’s claim that Popper’s Critical Rationalism ultimately depends on induction.
Bruce then makes a striking counter-claim: that Kieren’s entire argument amounts to stripping all substantive content from his “theory” of induction and turning it into an unfalsifiable concept—essentially a word game, a kind of argument-by-tautology designed to immunize the theory from criticism. Or put another way, Kieren is turning his theory into a concept because concepts are unfalsifiable.
This leads Bruce into a deeper examination of what induction actually is—and what it isn’t. Why is “induction” such a confusing, multidimensional idea? What is the real point of contention between critical rationalists and inductivists? Did Popper truly lack a notion of “support,” as Kieren argues? And what did Popper actually say about justification—did he really reject every form of it?
And to make things even more provocative: do CritRats rely on similar linguistic maneuvers to shield their own favored theories from criticism?
