The word "truism" comes to us with lots of connotations, not the least of which is that a truism is somehow "true". There's also the flavor of "vacuous and empty" at least in some language games i.e. one might accuse someone of "indulging in truisms" where a legitimate response to a truism is something like "so what?" or "you haven't said anything factual" ("tautologies" tend to be dismissed in the same way). Tthis is the kind of archeology of ordinary language that I consider consistent with the PI's investigatory approach. > For example, if I point out that the game of poker incorporates an element of > randomness and an element of concealment, while the game of chess involves > neither, those are "truisms".

Note that I say "akin" and by your example above a truism might be more an empirical statement (verifiable, could be wrong) that we all agree with because it is empirically true (not just because it makes sense to say in some grammatical sense). In ordinary literate discourse, people will say "that's just an empty tautology" sometimes. The typical example from the literature: "all bachelors are unmarried" (simply a reinforcement of definitions, like saying "all balls are round" -- then we could argue whether "round" means "spherical" as clearly the NFL style of football is more elongated and oblate, but still "round" we might argue). > PI 128 is not making a logical point, a la OC, about what it makes sense to > question or claim to know.

Here I would link to his "justifications (or reasons) come to an end" meme. If it makes no sense to contradict something, then to assert "belief" in that something also borders on nonsense. A "hinge" is less a believed true fact than a pivot point for a grammatical machinery. Shared "doing" more than shared "seeing" is a basis for a "form of life" in the OC sense. To this last point I would link Karen Armstrong's observations of Protestantism versus some other religious traditions, in that the former puts a premium on shared beliefs, agreements in theses, recitation of shared dogmas, whereas many other religions (according to Karen) are much more about sharing daily disciplines and habits -- somewhat irrespective of adhering to shared statements of faith. Indeed, when it comes to beliefs, some traditions encourage strong debate and contention as a way to keep any such formal apparatus self adapting and updating i.e. in every age we must "rehash" or "hash out" through a process of argument based in whatever rules (I'm thinking of the rabbinical tradition, of which Jesus was very much a part). As a practicing Quaker with on-line journals (a part of my practice), I find Karen's arguments useful for putting some distance between Quakerism and mainstream Protestantism. The former is less anchored in "credos" or "beliefs" and so is more like Zen in some respects. > The example "truisms" provides a nice segue to another point.

What I think of as a "mindset" is akin to Sean's notion of "cue cards" in that we're used to developing "chains of cues" i.e. trains of thought, where the segues are not in the nature of "iron clad logical switches" (as if we had no choice in the matter) but in the nature of reminders, mnemonic conventions, habits. Now that we have the Web, it's easy to describe mindsets in terms of hyperlinks and networks of web pages i.e. you can visualize a mindset as a convexity inside of which a thinking "bounces around" without escaping (until maybe the bubble bursts i.e. mindsets come with a "time to live" or "half-life" -- sometimes relatively short next to those "for the ages"). To practice philosophy in a Wittgensteinian manner requires developing some new habits of thought and Wittgenstein's writing is self-conscious of this didactic responsibility i.e. the author consciously designs interconnecting pathways linking "rule following" to "language games", "meaning" to "seeing according to an interpretation" and so forth. Setting up this infrastructure, designing a "track system" involves developing concepts through use, more than through plunking down some formal definition and saying "there, that's the meaning". In other words, it's through his usage of the term "language game" that we come to appreciate its sense, not through some simple enumeration of its possible meanings, as one might find in a dictionary. > > JPDeMouy > > Kirby -- >>> from mars import math http://www.wikieducator.org/Digital_Math ========================================= Need Something?
