Wordsworth Barbara - The notion that science does NOT proceed by cumulative inductions was first articulated by Popper. PKF built on that. (The rest of us spent decades trying to explain why induction was justified -- assuming all along that that was how science proceeded.) Popper argues further that the most productive experiments (and associated research programs) will be those that are the least likely to succeed as reasoned from what we know at the moment. Popper argued that we stand to learn the most from the success of the least likely to succeed experiment. What is meant by "productive"? (See below) Reasoning (so to speak) from a classical inductive framework one would expect that the best (most productive) experiments would be those most likely to succeed as reasoned from what we know at the moment. Herein you grasp the contrast with Popper. Counterinduction has a twist, not always appreciated. The "counter" is really qualitative and not just a simple negation (viz. a versus not-a). The "counter" direction is more like a dialectic. To generate the dialectic counter research program you look at the deepest assumptions you can articulate of the current, established and dominat research program and reverse them (note: how ever it is we do this it is not formally algorithmic). Then look for confirmations of your newly defined "counter research program". (This is the best way to get a sense of what Popper meant by the-least-likely-to-succeed-as-reasoned-from-current-understanding experiment.) So the tricky part is to understand that when you are reasoning about the probability of one hypothesis versus another -- in this context -- that the alternatives are really qualitatively distinct or incommensurable (i.e. there is no algorithm within the established theory to lead us to the new hypothesis of the counter theory). So quantitative comparisons can be misleading. Popper was NOT clear about this. His talk about the least and most probable experiments was understood by many (most) to entail that these alternatives existed within one logically homogeneous experimental framework. (And unfortunately, in the larger-than-science framework of inquiry they probably do make sense in one context. But not in any formalizable positivistic sense. Sorry if this is confusing. Many ships were lost in these waters.) ________________ What is meant by "productive" here is controversial. For the positivists the model of scientific inquiry was one of convergence -- the theories converge to a correspondence with reality. And that correspondence is what they suggested as the meaning of "truth". However, this model doesn't correspond (sic; noting the self-reference; science looking at itself) with the history of science. Kuhn et al. pointed out that since the overall Scientific Research Program develops qualitatively (viz. contains revolutions), it is impossible, or illegitimate, or wrong to try to represent it as one qualitatively homogeneous convergence. (And we have no independent access to "reality" to check our progress (viz. old Kantian point). For Popper and Feyerabend progress or a productive step in inquiry meant that you learned something that you didn't know (or understand) before. Popper/Feyerabend came to understand that this (rather obvious point (obvious after you think about it)) meant that the later theory must be at least partially incommensurable with the earlier; some qualitative differences. This means that the later theory can't just be a logical extension of the earlier. The "cumulative inductions" model of science entails a homogeneity of the accumulated inductions that is equivalent to a conceptual homogeneity (note: otherwise they can't be compared, mathematically). Popper and Feyerabend argued that if we really learn, then the conceptual system must "develop" such that conceptual homogeneity is violated: to learn is to make a conceptual advance. This was frequently argued in terms of the notion of "meaning variance" (= conceptual inhomogeneity). John Dewey and C.S. Peirce, it seems to me, made this point a generation earlier. Look particularly at Dewey's essays in "Experimental Logic". I like their aphorism: an advance in science is an advance in logic. (Also this means that an advance in science is an advance in scientific method - in the logic of reasoning about the next potential experiment; so the perceived problem of science here develops, emerges. -- But not in the positivist convergence model.) This is also quite in tune with the musings about quantum logic where the logic of the theoretical framework at any moment is linked to the nature of the elements (viz. objects of the concepts; particles, forces etc.) at that time in the history of the theory. So as our conceptual understanding of the electro-weak force changes so does the logic of the theory of science. If these last remark are correct then there is no "time-space invariant logic of science", no universal scientific method. If the "cumulative inductions" model of science were correct then there would be a "conceptually independent, universal, t/s-invariant logic of science." This is where Feyerabend and Lakatos realized that they were on the same path with Thomas Kuhn. ONE of the reasons this line of thinking has had political problems is that it entails that science is not and never has been an autonomous method of inquiry. It is simply part of the larger human enterprise. -- If you call yourself a scientist and that is how you get your money in life, then this is not a warm thought. WHERE does all this lead???? I think that it is fair to say that Popper "backed" his way into his eventual position. He argued in a variety of ways that the positivist model was wrong. Popper in this sense is himself an example of the "counterinductive inquirer". If you look at the BIG PICTURE of Popper's intellectual development you see that the positivists are committed to a "Closed Universe" model. Popper gradually discovered that if he were to be systematic about his opposition to the positivist model that he must, in effect, propose an "Open Universe" model. Briefly, a closed universe is qualitatively closed; nothing new really comes into it (sorry no revolutions here; no incommensurability); just algorithmic transformations amounting in the final analysis to nothing (absolute symmetry). (Note: John Barrow (U Sussex is currently writing a book about this aspect, entitled (guess) "Nothing"; cf. his current "Impossibility". An open universe allows for -- indeed requires -- qualitative change. MY best guess is that you can't make consistent sense of either of these models without the other. They are complementary, suggesting a quantum metaphysics.
