## Key lines

> From this observation we get a further view⁠—into Russell’s “Theory of Types.” Russell’s error is shown by the fact that in drawing up his symbolic rules he has to speak about the things his signs mean.

This insight reveals a problem with Russell's Theory of Types: his mistake is that when he creates rules for symbols, he must refer to what those symbols represent.

_Wittgenstein identifies a fundamental flaw in Russell's approach to logical syntax._
