  <description>&lt;p&gt;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 - &lt;a href="https://tannerlectures.utah.edu/_documents/a-to-z/p/popper80.pdf" target="_blank" rel="nofollow noopener"&gt;Popper's Three Worlds&lt;/a&gt;.
&lt;br&gt;In this episode we discuss:&lt;/p&gt;&lt;ul&gt;
&lt;li&gt;The &lt;a href="https://fallibleideas.com/taking-children-seriously" target="_blank" rel="nofollow noopener"&gt;TCS&lt;/a&gt; parenting movement &lt;/li&gt;
&lt;li&gt;Chesto's &lt;a href="https://twitter.com/mynameisChesto/status/1381798896960086016" target="_blank" rel="nofollow noopener"&gt;tweet&lt;/a&gt; to Deutsch&lt;/li&gt;
&lt;li&gt;How Popper's Three Worlds differs from Deutsch's Things/Qualia/Abstractions classification&lt;/li&gt;
&lt;li&gt;Would prime numbers exist if humans didn't exist?&lt;/li&gt;
&lt;li&gt;What constitutes reality?&lt;/li&gt;
&lt;li&gt;The existence of non-physical entities and the reality of abstractions &lt;/li&gt;
&lt;/ul&gt;&lt;p&gt; &lt;br&gt;Having a quick glance at the following wikipedia pages will help ground the conversation:&lt;/p&gt;&lt;ul&gt;
&lt;li&gt;
&lt;a href="https://en.wikipedia.org/wiki/Formal_system" target="_blank" rel="nofollow noopener"&gt;Formal systems&lt;/a&gt; &lt;/li&gt;
&lt;li&gt;&lt;a href="https://en.wikipedia.org/wiki/Formal_language" target="_blank" rel="nofollow noopener"&gt;Formal languages&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="https://en.wikipedia.org/wiki/Modular_arithmetic" target="_blank" rel="nofollow noopener"&gt;Modular Arithmetic&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="https://en.wikipedia.org/wiki/List_of_rules_of_inference#:~:text=Rules%20of%20inference%20are%20syntactical,conclusion%2C%20if%20it%20is%20sound." target="_blank" rel="nofollow noopener"&gt;Rules of inference&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="https://en.wikipedia.org/wiki/Non-classical_logic#:~:text=Non%2Dclassical%20logics%20(and%20sometimes,extensions%2C%20deviations%2C%20and%20variations." target="_blank" rel="nofollow noopener"&gt;Alternative Logics&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;&lt;p&gt;&lt;br&gt;Errata:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Somewhere Vaden says English is a formal language. Nope definitely not - English is &lt;em&gt;natural&lt;/em&gt; language, which is distinct from a &lt;em&gt;formal&lt;/em&gt; language.  &lt;/li&gt;&lt;/ul&gt;&lt;p&gt;&lt;br&gt;Send us your best guess for whether or not we're real at &lt;em&gt;incrementspodcast@gmail.com.&lt;/em&gt;  &lt;em&gt;&lt;br&gt;&lt;br&gt;&lt;/em&gt;&lt;br&gt;&lt;/p&gt;
