Yeah, Popperian falsificationism is the best empirical approach to science, but it is insufficient when it comes to a priori reasoning. Popper really had a knack for understanding the fallibility of people, including taking any other person's assertions on faith or assuming that a definition was THE authoritative definition. But to call all a priori reasoning trivial in the sense of NEVER telling us anything directly about the real world is absurd, not to mention the argument defeats itself.
One must only be aware of the tenuousness of definitions and context, and aware of the need for independent logical verification and independent empirical uncertainty and falsification to achieve a sufficient "criticalness" to their rationalism.
I haven't read enough to know about the fire poker argument, I should like to though. Sounds intriguing!
I completely agree 😄.
Well, the fire poker argument was on absolute ethical norms: Popper said there were, LVW said that there weren’t.
So by what you’re saying you’re pretty much already aware of how it went: Popper trolled Wittgenstein, and he got (reasonably) mad and stormed away. Which is a win in my eyes, since Popper was not intending to collaborate, just doing silly nit-picking.
Knowledge (scientific or not) requires a priori assumptions, denying that not all valuable information comes from reasoning is… silly in itself... and easily falsified.
