This is a letter to young men in their formative years, the ones that like to listen to Jordan Peterson or Ben Shapiro. This is the message:
There is an aesthetic of rationality, which entirely distinct from rationality itself.
This has two immediate corollaries.
One, just because someone adopts the aesthetic of rationality does not mean that they are doing a good job of practicing it. And just because someone does not adopt an aesthetic of rationality does not mean that they are not in fact practicing it well.
Two, now that you know this you may free yourself from the aesthetic of rationality, which is frankly boring and lame. Make yourself likeable, which is mostly about being kind and funny. You will learn more and be more convincing when you speak if you are likable.
