#24 - Popper's Three Worlds

This episode begins with a big announcement! Ben has officially become a cat person, and is now Taking Cats Seriously. Vaden follows up with some news of his own, before diving into the main subject for today's episode - Popper's Three Worlds.

In this episode we discuss:

• The TCS parenting movement 
• Chesto's tweet to Deutsch
• How Popper's Three Worlds differs from Deutsch's Things/Qualia/Abstractions classification
• Would prime numbers exist if humans didn't exist?
• What constitutes reality?
• The existence of non-physical entities and the reality of abstractions 

 
Having a quick glance at the following wikipedia pages will help ground the conversation:

• Formal systems 
• Formal languages
• Modular Arithmetic
• Rules of inference
• Alternative Logics

Errata:

• Somewhere Vaden says English is a formal language. Nope definitely not - English is natural language, which is distinct from a formal language.
