About this Episode

Why do logic and mathematics work so well in the world? Why do they seem to describe reality? Why do they they enable us to design circuit boards, build airplanes, and listen remotely to handsome and charming podcast hosts who rarely go off topic?

To answer these questions, we dive into Chapter 9 of Conjectures and Refutations: Why are the Calculi of Logic and Arithmetic Applicable to Reality?.

But before we get to that, we touch on some of the good stuff: evolutionary psychology, cunnilingus, and why Robin is better than Batman.



“The indescribable world I have in mind is, of course, the world I have ‘in my mind’—the world which most psychologists (except the behaviourists) attempt to describe, somewhat unsuccessfully, with the help of what is nothing but a host of metaphors taken from the languages of physics, of biology, and of social life.”

“In so far as a calculus is applied to reality, it loses the character of a logical calculus and becomes a descriptive theory which may be empirically refutable; and in so far as it is treated as irrefutable, i.e. as a system of logically true formulae, rather than a descriptive scientific theory, it is not applied to reality.”
