scientific realism vs antirealism

According to the deductive-nomological (DN) model of explanation, pioneered by Hempel (1965), “Event b occurred because event a occurred” is elliptical for an argument like: “a is an event of kind A, b is an event of kind B, and if any A-event occurs, a B-event will occur; a occurred; therefore b occurred”. Mach, E. (1893), The Science of Mechanics, trans. McMullin, E. (1991), “Rationality and Theory Change in Science”, in P. Horwich (ed. Subsequent history favored Bohr over Einstein. They are positivists because of their pro-science stance; they are logical positivists because they embraced and used the formal logic techniques developed by Frege, Russell, and Wittgenstein to clarify scientific and philosophical language. Putnam argues that this is a bizarre re-description of what we would normally say: they were (a) talking about the same entity and (b) making new discoveries about it. (It is noteworthy that Putnam recanted internalist truth in his last writing on these matters (Putnam 2015)). etc. (1970/1962), The Structure of Scientific Revolutions. Oxford: Clarendon Press. More fine-grained accounts have been proposed (Kitcher 1993; Wilson 1982, 2006) which acknowledge the complicated evolution of science and language yet avoid metaphysical extravagance. To a first approximation, scientific realism is the view that well-confirmed scientific theories are approximately true; the entities they postulate do exist; and we have good reason to believe their main tenets. In realist (or externalist) semantics the world leads and content follows: content is determined causally and historically by the way world is; the content of “water” is H2O. For him, a theory T is a semantic object, the class of models, A = , that satisfy its laws (where D is a set of objects and Ri are properties and relations defined on them). Stanford, P.K. Unlike rules, (i) they are individually imprecise and incomplete, and (ii) they can collectively conflict (and there is no a priori method to break ties or resolve conflicts). In particular, we cannot coherently suppose that “electron” does not refer to electrons because this is but a step away from a formal contradiction—some electrons are not electrons. To accept a theory is to believe it is (approximately) true. This natural line of thought has an honorable pedigree yet has been subject to philosophical dispute since modern science began. Premise 2a: For Putnam the distinction between realism and idealism is fundamentally semantic. Yes, we build them to be successful, but their scope and novel predictions generally greatly outstrip our initial intentions. A. (Two things about PUA are worth noting. The problem is not how to extend our epistemic and semantic grasp to objects separated from us by a metaphysical chasm; it is the more ordinary, scientific problem of how to extend our grasp from nearby middle-sized objects with moderate energies to objects that are very large, very small, very distant from us spatiotemporally, and so forth. The laws of physics lie, Cartwright claims, and the hope of a true, unified, explanatory theory of physics is either based on a misunderstanding of physics practice or a vestige of 17th century metaphysical hankering for a neatly designed mechanical universe. But if reference is determined by causal-historical relations (§5c), then the references of some key terms of T get lost in the transition to T*—“ether” was a key referring term of classical physics, but there is no ether in special relativity; so how can classical physics capture part of the same facts that special relativity captures when all its claims about the ether are either plainly false or truth valueless? Suppose Gauss’s experiment gave the angle-sum of a triangle as 180º. Rather the best explanation must be characterized in terms of properties like “loveliest” or “most explainey” (Lipton 2004). Poincaré proposed conventionalism: we decide conventionally that geometry is Euclidean, forces are Newtonian, light travels in Euclidean straight lines, and we see if experimental results will fit those conventions. Deflationists argue that such “thin” concepts and trivial relations cannot bear the explanatory burdens that scientific realists expect of them. As a result, physicists became increasingly preoccupied with foundational efforts to put their house in order. There are rival explanations that are compatible with CE, and some of them are more plausible than realism. Jules Vuillemin, Princeton: Princeton University Press. Sixth, constructive empiricists claim that constructive empiricism is better than scientific realism because it explains science without extra epistemic risk. However, these arguments may be directed at a straw man, since no realist is likely to require that every regularity be explained. As native speakers, we know, without empirical investigation, that “electron” refers to electrons just by having mastered the word “refers” in our language. The amount of items that will be exported is indicated in the bubble next to export format. Intuitively, truth* and reference* are not truth and reference but gerrymandered relations that mimic truth-in-M and refers-in-M, where M can be entirely arbitrary, provided it has enough objects in its domain. Pragmatists question metaphysical realism (SR3): it presupposes a relation between our representations (to which we have access) and a mind-independent world (to which we lack access), and there cannot be such a relation, because mind-independent objects are in principle beyond our cognitive reach. Hertz, H. (1956), The Principles of Mechanics. Digital access to this material is made possible by the University Libraries, University of Arizona. To understand “No emerald is blue” one need only know the verification conditions for “This is an emerald”, “This is blue” and the logical relations of such sentences to “No emerald is blue” (for example, that “no emerald is blue” implies “if this is an emerald, then this is not blue”, and so forth). Two theories, T and T’, are empirically equivalent if all the observables in a model of T are isomorphic to the observables in a model of T’. Scientific Realism and Antirealism Debates about scientific realism concern the extent to which we are entitled to hope or believe that science will tell us what the world is really like. The Realism vs. Anti-Realism Debate The mid-1980's saw a transformation of the debate over "scientific rationality" which had been unleashed by Kuhn's perceived challenge to the traditional claim that scientific belief is determined by evidence and reasoning. Finally, because of their meta-level appeals to IBE, they are committed to SR5 because it best explains the instrumental success of our best theories and the increasing instrumental success of sequences of theories (where T* is more successful than T because T* is closer to the truth than T), and so forth. Hempel, C. G. (1965), Aspects of Scientific Explanation. IBE thus needs no more justification than does modus ponens—each is part of the very practices that constitute what rational inference is. Our question is this: Is scientific realism an adequate way to think about science or does some form of antirealism make more sense? Stanford argues that realists can avoid this problem only if they can provide prospectively applicable criteria of selective confirmation—criteria that past theorists could have used to distinguish the good from the bad in advance of future developments and that we could now use—but they did not have such criteria, nor do we. Empiricists attempt to set limits: we should believe only what science tells us about observables. By contrast, “phlogiston” does not refer since nothing has the properties that the phlogiston theorists mistakenly believed to be responsible for the body of information they had about oxidation of metals, and so forth. Psillos (1999) employs causal descriptivism to deal with this problem: “ether” in 19th century theories refers to the electromagnetic field, since that (and only that) object has the properties (medium of light-propagation that is the repository of energy and transmits it locally) that are causally responsible for the relations between measurements we get when we perform optical experiments. Hacking, I. The positivists inherited this distinction from Kant, but, unlike Kant, they rejected synthetic a priori truths. This is just what it is to have evidence for something. For some T-T* sequences in mathematical physics, there are limit theorems whereby T can be derived as a special case of T* under appropriate limiting conditions. Consequently, internalist truth lacks the properties of truth. In the 1740s English-speakers lacked such uniquely identifying knowledge, though we would naturally say they were using “water” as we do — to refer to H2O. Wilson, M. (1998), “Mechanics, Classical”, in Edward Craig (ed. Harman, G. (1965), “The Inference to the Best Explanation”, The Philosophical Review 74, 88–95. On the other hand, skeptics see the history of science as supporting a pessimistic meta-induction: since some (many, most) past successful theories turned out to be false and their core terms not to refer, so too current successful theories may (are likely to) turn out to be false and their key terms not to refer. formats are available for download. This week we will again debate a controversial issue together in class. Moreover, scientific developments undermined several theses formerly taken as necessarily true. SR4     Theories are literally true (when they are) partly because their concepts “latch on to” or correspond to real properties (natural kinds, and the like) that causally underpin successful usage of the concepts. Similarly, structuralists suggest, the structure of relations that obtain between scientific objects is distinct from the nature of those objects themselves. None is likely to convince any realist (Musgrave 1985; Stanford 2001). More generally, 17thcentury protagonists of the new sciences advocated a metaphysical picture: nature is not what it appears to our senses—it is a world of objects (Descartes’ matter-extension, Boyle’s corpuscles, Huygens’ atoms, and s… On this interpretation, the positivist project provides epistemological foundations for problematic sentences of science that purport to describe unobservable realities, such as electrons, by reducing sentences employing these concepts to unproblematic sentences that describe only observable realities. Antirealists take a diametrically opposite view, that a theory should never be regarded as truth. This paper operates under the following two assumptions: First, there will be scientific revolutions, as there were before the early twentieth century. These conventions cannot be experimentally refuted or confirmed since experiments only have physical meaning relative to them. Cambridge: Cambridge University Press. In rejecting conventionalism, Duhem and Quine claim that we may keep H and reject one of the Ais to accommodate not-O: any statement may be held true in light of disconfirming experience. Horwich, P. (1990), Truth. Finally, like any inferential principle that amplifies our knowledge, conclusions inferred by IBE are fallible: while they are more likely to be true, they could be false. There is a crisis that only a revolutionary new paradigm (for example, STR, QM, and GTR) can handle. Thus Cartwright is anti-realist about fundamental laws: contrary to realists, they are not (even approximately) true; contrary to van Fraassen, she is not recommending agnosticism—we now know they are non-factive. Newtonian mechanics, phlogiston theory, humors in medicine) and thus that their theoretical objects do not exist. For this to be a concrete (physical) fact, God would have had to create some objects—nucleons with symmetrically related isospin states or some more fundamental objects that compose nucleons—to occupy the neutron- and proton-nodes of the SU(2) group-structure. Princeton: Princeton University Press. Between 1990 and 2016 new versions of the debates, many focusing on Laudan’s PI (§7b), have emerged. Thus, for example, a clause like “‘electron’ refers to electrons” would be on this list if the language were English. The basic equations of Newton, Maxwell, Einstein (STR/GTR), quantum mechanics, relativistic quantum mechanics, and so forth, are typical examples of such laws. Oxford: Oxford University Press. Cartwright, N. (1999), The Dappled World. Boyd, R. (1983), “On the Current Status of the Issue of Scientific Realism”, Erkenntnis, 19, 45–90. Its proponents argue that it can account, for example, for apparently indistinguishable particles in entangled quantum states. Their separation into realists and antirealists is complicated, but Helmholtz, Hertz, Kelvin, Maxwell, and Planck had realist sympathies and Duhem, Mach, and Poincaré had antirealist doubts. We now see why SR is committed to SR3 and SR4 above. In the latter contexts, “light-wave” referred to the ether (that is, nothing), a mode of reference that was presupposed yet empty, idle, and not retained in later theories. Oxford: Oxford University Press. Here we look at premise 2, which follows logically from: 2a. Structuralists respond that, though ontologies come and go, our grip on the underlying structure of the world steadily improves. The very strong, very general conclusion of EET, however, depends on the very strong, very general Premise 3, which, critics argue, is typically supported either by “toy” examples of theory-pairs from the history of physics, by contrived examples of theories, one of which is transformed from the other by a general algorithm (Kukla 1998), or by some tricks of formal logic or mathematics. Carnap, R. (1936), “Testability and Meaning”, Philosophy of Science 3, 419-471. A theory T is empirically adequate if and only if what T says about all actual observable things and events is true (that is, T saves all the phenomena, or T has a model that all actual phenomena fit in). And even if there were natural kinds, it seems unreasonable to expect that language could neatly lock onto them: why should our accidental encounters with various samples in our limited part of the universe put us in a position to lock onto universal kinds? For empiricists, cumulativeness requires at least that T* have more true (and perhaps less false) observational consequences than T. Since the content of a theory on logical positivists’ views is exhausted by its observational consequences, if T* has more true observational consequences than T, then T* is “more true than” T. However, SR-realists require more. The positivist may respond that they cannot be directly sensed, and are thus unobservable, but why should being directly sensed be the criterion for epistemological or semantic confidence? REALISM VS. ANTI-REALISM 1) “No miracles” argument: Supports realism. Simply arguing (with Hardin and Rosenburg) for preservation of reference via preservation of causal role is too easy: do Aristotle’s natural place, Newton’s gravitational action, and Einstein’s space-time curvature all play the same causal role in explaining free-fall phenomena? Pragmatic acceptance involves non-epistemic commitments to use the theory in certain ways (basing research, experiments, and explanations on it, for example); commitments are neither true nor false; they are either vindicated or not. However, scientific realists’ arguments and their interpretation of SR1 and SR2 often presuppose further commitments: SR3     There is a determinate mind-independent and language-independent world. In this way Kuhn (1977) offers a middle ground between theory choices being completely subjective and being objective (qua being determined by rules applied to evidence). Even if those objects had only structural properties, they would have to have one non-structural property—existence (van Fraassen 2006, 2008). Coulomb’s law, FC = kq1q2/r122, tells us what the electrostatic force between two charged bodies is. But there is a more mundane explanation: many very smart people construct our scientific theories and methods, throwing out the unsuccessful ones (which we tend to ignore (Magnus and Callender 2004)) and refining and keeping only the successful ones. Psillos, S. (1995), “Is Structural Realism the Best of Both Worlds?”, Dialectica 49, 15-46. Thus CE can agree with SR that at most one of T, T’ can be true and to be a realist about that theory is to believe it is true (SR2). Although Tarski’s definition is technically sophisticated, the main points for our purposes are these. Idealism fails to explain the practice and its success, while SR succeeds. (1980), The Scientific Image. Second, there is ontological structural realism (OStR), advocated by Ladyman and others (Ladyman and Ross 2007) and similar to Quine’s realism (§4). Epistemic acceptance is belief; beliefs are either true or false. Second is the covering law (or DN) model of explanation (Hempel 1965, §3c): a correct explanation of a phenomenon or phenomenological law is a sound deduction of the explanandum from fundamental laws together with statements describing, for example, compositional details of the system, boundary and initial conditions, and so forth. New York: The Science Press. Liston, M. (2005), “Does ‘Rabbit’ refer to Rabbits?”, European Journal of Analytic Philosophy 1, 39-56. So, though everyone was converted to atomism, no one understood what atoms were. Realists often add that, given the spectacular predictive, engineering, and theoretical successes of our best scientific theories, it would be miraculous were they not to be approximately correct. Third, although we should reject IBE, we should embrace inference to the most likely cause (ILC). There is no paradigm-independent reason for preferring P* over P, since such reasons would have to appeal to something common (common observations, methods, or norms), and they share no commonality. Relativity theorists felt bound to have Newton’s theory derivable in the limit from Einstein’s theory.
