Is Tractatus about the Philosophy of language or Philosophy of logic. I was hearing John Searle's lecture and he said there are two strands in Philosophy of language :- 1. Logical theory of language 2. Use of language theory
So, if language is just a matter of logic, isn't logic itself is a language because to say "logically follows" you must express your thoughts and expressing your thoughts is the field of Philosophy of language.
So, is Tractatus about Philosophy of language or Logic.
