J: 1. Philosophical Grammar was the product of work he started in the Fall term of 1930. The ideas that show up in 33 are being first aired in 30 (or at least their incarnation). I would not draw the line at the completion of PG, I would draw it when those ideas are swimming in the head. To really know the specifics of the development, we'd need to see lecture notes from the Michalmas term in 1930, and compare them to Alice Ambrose and others. Are the 1930 notes around somewhere? 2. I don't have the Ambrose lecture book handy right now (its at home), but the preface to that book indicates that the notes from 1932 are the most unreliable on her part, because she only had her own notes as a source. The other years had other sources. Finally, she does mention that the notes reflect only "her understanding" of what was said. (Also, some of the "notes" are actually reconstructions -- she went back and wrote out sentences for them. I think they ought to be regarded as a kind of testimony). [Tangent -- Still, my examination of those notes (which were from lectures around 1934) found them immensely helpful. I had never seen Wittgenstein presented so clearly before. However, one of the criticisms might be that the points have been made simple. I haven't read enough to form a judgment, but I do know that I was thoroughly enjoying what I was reading. I'll be getting back to that soon]. 3. I'm not quite getting what you are on some of this. But I'm not looking at it closely (sorry if I'm off base). > The phrase > "length of interval" has its > sense in virtue of the way we determine it, and differs > according to the method > of measurement I was thinking meaning is use, here. > We cannot > say that two bangs two seconds apart differ only in degree > from those an hour > apart, I had understood this to say that one is a psychological estimate, the other isn't. This is the sense of interval. He's taking what are thought to be analytic ideas -- length, interval -- and showing that they have senses which are conveyed only "in action." 4. Please remember, the point at which the caterpillar turns to a butterfly is not mine. I am repeating what I read in Monk. I'm obviously not saying -- and neither was Monk -- that there was not continued development (which there surely was). What I am saying is that the critical period when he broke from the Tractarian ideas (that he did break from) happened in late 1930. There is all sorts of historical conversation about it. Imagine an iceberg that cracks in half, with part II sailing away. That portion of the ice broke and fell away in late 30. What broke it was the new vision. He spent the next several years trying to explicate, clarify and polish it. Regards and thanks. Dr. Sean Wilson, Esq.
