Ricoeur's Own Linguistic Turn

I want to discuss why it makes sense to speak of a linguistic turn in the philosophy of Paul Ricoeur. He early on had said that "the word is my kingdom and I am not ashamed of it" without, at that time, spelling out just what this claim meant as regards a broader philosophy of language. Nor would he have had any difficulty in admitting that his attitude toward language and questions about language changed over time.
