I don't mean to suggest that this common family of arguments exhausts the arsenal of antirealists. As I'll concede explicitly in section 9, further challenges remain.

I owe to the editors of the Philosophical Review the suggestion that this is unnecessarily cautious and that the NEA can be traced to the ancients. That suggestion may well be correct. My hesitation is based on the possibility that attributing to ancient or medieval thinkers a concept of action-guiding representational states may be an anachronism.

It's worth being explicit about the relation between real realism and NOA. As pointed out in note 4, one difference is that the realist thinks we can make sense of a notion of mind-independence and use it to develop a more substantive notion of truth than Fine would allow. Real realists also believe that Fine's "homely" argument for acquiescing in science is weak (on an uncharitable reading, the NOAer appears at least uncritical if not credulous) and that, in consequence, the brief for democracy fails. As we'll see, real realists agree that their views should be supported by "homely" considerations ('The Natural Ontological Attitude," 126) but believe that Fine has mislocated them.

It's possible to argue that contemporary understanding of the neurophysiology of color perception reinforces the antirealist cause by undermining the reductivist project. But, as Peter Bradley and Michael Tye have shown, in currently unpublished work, the details of the neuroscience can be exploited to identify more subtie reflectance properties of surfaces, and thus to generate a more sophisticated reduction.

Perhaps another would be to concede the point for secondary qualities and argue that only primary qualities matter to science, a view popular with some historical figures. This reply seems to me weaker, both because it raises the possibility that analogues of the skeptical arguments might be generated against some of the primary qualities and because of the apparent role that secondary qualities play in some areas of science (for example, in evolutionary biology).

Of course, an immense amount of ink has been spilt on questions about the status of secondary qualities, from the early modern period to the present, and there are many versions of both strategies I mention here, as well as arguments for and against them. I believe, however, that both strategies remain promising.

I suspect that the argument via (4b) may articulate more fully the appeal to variation in belief that leads historians and historically-minded sociologists of science to oppose realism.

Thus, a set E is an admissible extension for a theoretical predicate T just in case there's a model of the first-order formalization of the theory in which T occurs in which all observational terms receive their standard extensions and T is assigned E. A theoretical predicate is fully interpreted if it has a unique admissible extension, partially interpreted if it has more than one admissible extension. Two points in this formulation deserve note. First, it should be clear that this is a reconstruction of a notion of partial interpretation that evolved over two decades (from the late 1930s to the early 1960s). Second, there may be tacit acceptance of further restrictions on acceptable partial interpretations. Thus, it seems likely that the domain is restricted to mathematical entities and physical objects, and that there are conditions on the extension of theoretical predicates (for example, that an n-place predicate be assigned a set of n-tuples whose kth members are physical objects);

This idea-the "ultimate argument" for realism-became popular in the 1970s, largely because of the formulations of J. J. C. Smart, Putnam, and Boyd. It has deep historical roots. Descartes, for example, defended parts of his physics on the grounds that his successes would be incomprehensible unless his theoretical hypotheses were right.

In both instances these formulations are not entirely precise. The first is intended to allow for "predictions about the past," for example, paleontological statements that identify the likely whereabouts of as yet undiscovered fossils. The second is vague about how complete the instructions have to be (it would be folly to insist that they specify a mechanical procedure, for example) . Attending to the niceties of precise formulations would divert us from the main points of the present discussion.

Laudan provides a long list in "A Confutation of Convergent Realism." His list includes such things as the humoral theory of medicine, catastrophist geology, and theories of spontaneous generation. In none of these examples does it seem right to hail the theory as successful or to judge that the proponents of the theory were justified in holding it to be successful. Other doctrines on his list are more intractable.

Fresnel submitted a memoir presenting his theory in a prize competition sponsored by the French Academy of Sciences. One of the jurors, Poisson, a proponent of the corpuscular theory of light, recognized that Fresnel's principles implied that there would be a bright spot at the center of the shadow of a small, rotating disk, thinking that this would provide a reductio of the theory. Another juror, Arago, performed an experiment to check, and discovered the bright spot. It is a nice irony that it is named for Poisson, who had been so confident that it did not exist.

The most prominent example for developing the transcendental strategy starts from Goodman's new riddle of induction, claiming that justified views about what predicates (or classes) are projectible must advert to hypotheses about underlying mechanisms. So, for example, geologists might legitimately project a claim about certain minerals because they believe that the minerals in question share a common microstructure that gives rise to their observable properties. Without this background belief, they would not be warranted in taking the predicates they employ to be projectible, and thus would have no justification for the commonplace types of induction that empiricists accept. For development of points like this, see Boyd "Realism, Approximate Truth, and Philosophical Method."

One obvious worry is that antirealists will be able to advance some other account of the justifiability of such things as projectibility judgments-as for example in Goodman's own suggestion that projectibility is measured by entrenchment (see the final chapter of Fact, Fiction, and Forecast).

rather E*is novel evidence for T only if T already had an episte mological basis E that doesn't include E*. Yet if there's an epistemological basis for the theory of any kind it appears either that realists have exactly what they want-to wit, evidence for believing that the theory is true, or that the epistemological basis only allows for acceptance of the theory as empirically adequate. If the former, then the question has been begged against the anti-realist;

The telescope was accepted remarkably quickly. Virtually all scholars admitted its reliability by 1615. Some of the early opposition was based on the difficulties of using telescopes, which yielded inconsistent results that could be exploited by Horky and others. Galileo worked both to improve the instruments and to offer guidance for their use, so that, within a year of the initial development, the major inconsistencies were resolved. (For valuable studies of the telescope and its validation, see the writings of van Helden.)

As we shall see, this is the basis on which to respond to the Fine-Rorty charge that realist theorizing about the sciences involves tacking on dubious metaphysical assumptions, and it is also the source of pertinent concerns about realism, to wit, that realists try to extend the everyday usage into areas in which the enabling conditions of the "everyday uses" do not apply; see section 9.

It's possible that an epistemological empiricist might object that I've mis-described the situation. Galileo didn't show that conclusions about unobservables could be justified through use of telescopes. Instead he changed the boundaries of the observable. But to make this response would undermine the empiricist strategy. For the notion of the observable has now been detached from the connection with unaided observation, and must now come to something like "detectable with a reliable instrument." Realists can sympathize with that notion of observability, formulating their views as claims about the reliability of particular detection devices. If those claims are to be debated by the epistemological empiricist by anything like the line of reasoning we're considering, then the empiricist will have to rely on a more basic level of observability to serve as the ultimate standard of validation. The Galilean achievement will then be seen in terms of justifying conclusions about entities that are unobservable according to this more basic conception.

Similarly, I suppose that we can contemplate the possibility of physical objects existing without supposing that we have to be observers, parts of the imagined scene

As we saw in section 3, realists ought to avoid the notorious "veil of perception" doctrine, according to which we perceive objects indirecly by perceiving sensa directly; the right thing to say is that we perceive the objects by being in (or "having") certain kinds of sensory states. The constructivist advocacy of (SC4) to accuse realists of engaging in metaphysics thus needs the kind of Austinian therapy I try to offer here.

This is how Putnam's celebrated arguments get started (see "Models and Reality," and the early chapters of Reason, Truth and History). Putnam proves a much stronger result than the standard conclusion that one can satisfy a set of sentences by permuting elements in the domain of the model; his construction reveals how the permutation can preserve the ways in which the truth values of sentences vary as the state of the world changes.

It should be noted that emphasizing the causal relations between the objects and the subject makes it look as though her language could be meaningful even in the absence of others, thus flouting the Private Language Argument (Wittgenstein, Philosophical Investigations, §§258ff.). But there's no need for realists to quarrel with this argument. The causal relations that fix meaning and reference can be taken to include relations among speakers. For the realist's purposes, the important point is not whether the causal constraints are so inclusive or whether they fix the referents for a group of speakers, but rather that they hold independently of the imaginary observer.

This is doubly mistaken, for there is an important difference between Quinean underdetermination (roughly, cases in which rival theories are supposed to receive exactly the same support from the same body of evidence) and Kuhnian underdetermination (roughly, cases in which rival theories are successful in rather different ways). In the text, I suggest that Quinean underdetermination has varying force in different areas of science. I have tried to address issues of Kuhnian underdetermination in chapter 7 of The Advancement of Science.

In part, the bogey of underdetermination may stem from the view that scientific theories are readily formalized and that the formalization will automatically lead to ways of constructing serious alternatives. My quick appeal to a central doctrine within molecular biology is intended to reduce confidence in this view. I have attempted to address issues about underdetermination more thoroughly (but probably still not thoroughly enough) in Science, Truth, and Democracy (New York: Oxford University Press, forthcoming).

Here real realism diverges from stronger doctrines held by some realists (for example Richard Boyd and Michael Devitt) and from my own earlier self (as in chapter 4 of The Advancement of Science).
