Not a very well-known book. In fact I believe there may be fewer than 10 copies in the US. (There are only 4 in university libraries, according to WorldCat.) Mine is a xerox of the copy from Columbia University Library. Nicholas Bachtin was the younger brother of Mikhail Bakhtin, a somewhat better known Russian literary theorist. I know of him because he was a good friend of Wittgenstein's. And I read this posthumous collection of essays to see if I could find any intersections of their work. Wittgenstein once said: "really one should write philosophy only as one writes a poem." It is completely unclear what Wittgenstein means by this. What seems slightly promising is that Bachtin has a lot to say about poetry. I'm still processing what he has to say for possible insights. Apart from the Wittgenstein connection, the essays have merits of their own. Bachtin was a linguistics professor, with a deep knowledge of Classical Greece and, of course, Russia--both interests of mine. I'm glad I read it, and it might make an appearance in my next book.
