The Courtiers of Confusion: A Reply to Wysocki and Block


  • ojsadmin ojsadmin



Igor Wysocki and Walter Block have offered a critique of my subjective definition for probability. In this article, I offer a detailed exposition of Wysocki and Block’s mistaken critique. I focus on the logical incoherence of their argument, as well as the inconsistency of their argument with Ludwig von Mises’s own ideas about probability. I also describe how Wysocki and Block have built their argument on a mistaken view of what subjectivists believe as well as a mistaken view of what the brothers von Mises held. I thus argue that Wysocki and Block have failed to redeem Ludwig von Mises’s approach to
