Where in the article is the allegation or assertion of invention? Wittgenstein was focused on the philosophy of language (see Tractatus, Philsophical Investigations, the brown book, etc). I would be interested in hearing your opinion on who contributed more to the philosophy of language. I didn't mind spending multiple semesters studying Wittgenstein - in fact, it has provided some of the most lasting impact over the many years since college. Also, not all philosophy is logic.
