Sean and Stuart, There was only one Wittgenstein. No, that's not to speak of his singular contribution to philosophical thought. Nor yet is it to indicate a commitment to readings which downplay the differences between the _Tractatus_ and later works. It's a reminder that we are dealing with a single human being, his life, and the development of his thought.. When we discuss and debate "transitional periods" perhaps we should pause to ask "from what?" and "to what?" And we should consider that we are always, all of us, changing in this way and that, going through transitions of various sorts. But surely there is a definitely sense to the idea that Wittgenstein's thought can be divided into various periods and that we can identify certain periods of his life as transitional between those periods? Certainly. But I want to ask, "What purpose does such a periodization serve?" There is the potential pedagogical value of simply giving a bit of organization to the story of his life and work. If that were the only thing at issue, what would be the point of debating one classificatory scheme or another? Another way of asking my question: what are we to do with a system that divides Wittgenstein's work into periods? What use is it? What follows from a particular work being placed in one period or another? Considering such questions isn't merely about assessing the importance of a controversy and putting disagreements into perspective (something I am all too aware can easily be lost), but perhaps a clue to how we should go about answering more specific questions about various schemes and the place of various works within those schemes, possibly even a clue to the role and weight appropriate to various testimony. For me, the main value in grouping Wittgenstein's work into periods is interpretive. I'll specify what I mean by that shortly but first I want to say that a biographer or historian may have other purposes, equally legitimate for their work, and that with different purposes they may also arrive at somewhat different schema. This may have some relevance to disputes in these matters, though I haven't thought through or researched what specific differences might arise. As for the value of grouping Wittgenstein's works into periods for purposes of interpretation, I would elaborate by saying that such periodization provides a "rule of thumb" (or several such rules) for assessing how far we should go, when comparing remarks from different works, in trying to reconcile seeming contradictions or resolve apparent tensions. And when we should be more or less inclined to stop and say, "No, he clearly changed his mind between these two works." Or, applying such a rule of thumb to a closely related problem, we could ask, "To what extent are remarks in this work a useful guide to understanding remarks made in another?" Here, periodization suggests that some groupings of works (works from the same period) are more likely than other goupings (works from distinct periods) to represent a cohesive set of views. Works from one period are then presumably less reliable as tools to help us understand works from a different period than works from the same period would be. That is basically what such a "rule of thumb" would tell us. But note: such a rule of thumb tells us only where our presumption should be. It is not conclusive. Note as well that "less reliable" does not mean "useless". First of all, even works which seem to clearly disagree may still assist us in understanding why Wittgenstein changed his mind. Second, there's no reason to suppose that, even between TLP and OC, there are not some points of agreement. In considering a scheme that groups Wittgenstein's thought and works into periods, we should consider several questions: Is it a matter of positions being discarded or of positions being added? Or both? And how central are the positions in question to the overall way of thinking? And we may try to draw a distinction between a new position and a position undergoing some refinement. We may also attempt to draw a distinction between a change of position and a change in how that position is presented. Some caveats to consider here. First, referring to "positions" ought to give us pause in considering Wittgenstein's works. This requires some elaboration and careful reflection. Second, we shouldn't be to rigid in distinguishing between positions and their presentation (between content and form) in Wittgenstein's works because the presentation itself is relevant to the wider conception of philosophy, to understanding the purpose that elucidations are meant to serve. But an example: I would be inclined to call the differences between PI 1-188 and later work (the remainder of the PI and final works on philosophy of psychology, color, and epistemology) "additions". I don't see the insights of the beginning of the PI being rejected but rather new insights, consonant with those, being incorporated. And within those later works, I see more refinements of position and changes in presentation than anything else. Still, these last works are clearly "work in progress" and Wittgenstein, had he lived, would undoubtedly have continued working over them. I've deliberately chosen an illustration that sidesteps the current controversy and that is, I would hope, not contentious to either side. But now, I'll venture to indicate how my own rules of thumb would compare and contrast with both of your positions. The period of 1929/1930 was a period of casting off key theses of the _Tractatus_. If any period is rightly called "transitional" it is this one. Core ideas in the early work were being reconsidered and rejected. It wasn't enough to refine positions in light of the color exclusion problem.. It was as if Wittgenstein were on a ship that kept springing leaks faster than he could repair them. He had to abandon ship. (Another metaphor is falling dominoes.) A case could readily be made that by the end of this period, Wittgenstein had at least a general of where he needed to go by the end of this brief period. But there is still a vast difference between someone saying, "Eureka!" (or, “The nimbus of philosophy has been lost.") and Athena springing forth, fully armed and armored, from the head of Zeus! There are refinements and additions (as noted in, e.g. G.E.Moore's lecture notes) throughout 1930-1933, culminating in the work we now know through _Philosophical_Grammar_ and the section "Philosophy" included in _Philosophical_Occasions_ and finally published together in _The_Big_Typescript_. And even in that 1933 work, there are also approaches to problems (especially in mathematics and formal logic) that show vestiges of the old way of thinking. Moreover, even in the 1933 work, we see various experiments and we do not see all of the later themes - certainly not in their mature form. But there's a vast difference between saying that he was still developing his new approach and saying that he was still breaking free of the Tractatus. It seems to me that Sean is using "transitional" to mean "still breaking free of the _Tractatus_" and Stuart is using "transitional" to mean "still developing his new approach." Sean says that Wittgenstein had broken free in 1930. I am inclined to describe this as a longer process, but a process that we could say was well completed in 1933, with the works mentioned. (But consider, OC 321. The temptations of TLP are perhaps never fully exorcised, only more quickly recognized for what they are. Still, if we take that line, then it's all "transitional". We could say that, but it would be quite misleading.) The period between 1933 and the completion of PI 1-188, the period in which _Blue_and_Brown_Books_ were composed, is another matter. Stuart is right that there are refinements, e.g. of the role and purpose of discussing "language games", some of which could be called refinements of presentation and some refinements of position. But these are additions to the new method, not rejections of ideas from the _Tractatus_! We could say he was "in transition" (aren't we all?) but transitioning from what? To what? If we call this "transitional", having already used that word to describe the transition away from the ideas of the _Tractatus_, that can only mislead! The idea that he was still, in the latter half of the 1930s, "transitioning" away from that early work is very misleading. Now, I've put forth what I see as the value in arranging Wittgenstein's works into periods. The "rule of thumb" I've proposed would suggest that we should not expect consistency between the later works and works such as _Remarks_on_Logical_Form, the _Lecture_on_Ethics_, _Philosophical_Remarks_ and the various lectures recorded between 1930 and 1933 (though of course lecture notes raise other questions of reliability as well). When we encounter an apparent contradiction, it is well warranted to say, "He changed his mind". And these works are not a good guide to interpreting later remarks. Remarks we know from _Philosophical_Grammar_ and _Big_Typescript_ and moreso, _Blue_and_Brown_Books_ should show much more consistency with still later work, but where there is a clear inconsistency with _Philosophical_Investigations_, we should still say, "He changed his mind." That doesn't mean we should say, "He still hadn't rejected _Tractarian_ ideas," or, "He hadn't yet started doing philosophy in the new way," but simply that he was constantly developing and refining both his ideas and his way of presenting them. More importantly, it is perfectly legitimate, in the absence of inconsistencies, to cite remarks from 1933 onward as evidence of Wittgenstein's later views. Part of this "rule of thumb" is that the burden shifts from a presumption of unreliability or possible inconsistency to a presumption of consistency. The burden is on the person challenging the reliability of a remark to show that it is contradicted by remarks in the canonical PI 1-188 or should be rejected on the basis of methodological remarks from PI 89-133 in that same canonical collection. Now, calling something a "rule of thumb" suggests that there is a more refined and reliable (but presumably less convenient) method available that this rule. But it may also be that there are merely several complementary rules and that any refinement comes from weighing the results of each. In any case, the guidance a rule of thumb offers is defeasible. I've indicated how a remark from BTS, PG, or BB might be rejected. But there are also narrower cases where the rule itself would be rejected or refined.. For instance, I would not take a remark from 1933 about impossibility proofs in mathematics as presumptively consistent with and accurately reflecting all of his later views on mathematics. As we go deeper, the rule of thumb becomes less valuable than the careful, painstaking process of close reading and comparative study.
