Why Anti-Realism Breaks up Relationships

Some theologians are inclined to regard realism with hostility or indifference. I do not present an argument for realism, but for why realism matters, and what is at stake.
First of all, I separate the heart of realism from gratuitous doctrines which are too often associated with it. Religious realism is the claim that truth is independent of our beliefs about truth, and that we can in principle hope to have true beliefs about God. Realism is not intrinsically concerned with the existence of 'objects', with natural theology or rational justification.
I then show that even thinkers who are hostile or indifferent to religious realism so defined, usually make an implicit appeal to a similar realism in the sphere of ethics.
To establish that realism matters in religion as well as ethics I draw an analogy with realism/anti-realism about persons, to show that anti-realism makes mutually risk-taking and courageous relationships impossible. I go on to argue that far from it being a realist who is obsessed with rational certainty, this is one of the worst vices of the anti-realist, who cannot bear there to be a gap between her beliefs and reality.
I conclude that the most vital feature of religious realism is not certainty of belief, but the opposite – the acknowledged risk that all our hope could be in vain. In closing the possibility on this risk, the anti-realist demonstrates an unfaithful and uncourageous movement of thought.     

Causal explanation and scientific realism

It is widely believed that many of the competing accounts of scientific explanation have ramifications which are relevant to the scientific realism debate. I claim that the two issues are orthogonal. For definiteness, I consider Cartwright's argument that causal explanations secure belief in theoretical entities. In Section I, van Fraassen's anti-realism is reviewed; I argue that this anti-realism is, prima facie, consistent with a causal account of explanation. Section II reviews Cartwright's arguments. In Section III, it is argued that causal explanations do not license the sort of inferences to theoretical entities that would embarass the anti-realist. Section IV examines the epistemic commitments involved in accepting a causal explanation. Section V presents my conclusions: contra Cartwright, the anti-realist may incorporate a causal account of explanation into his vision of science in an entirely natural way.     

Negation,anti-realism,and the denial defence

Here is one argument against realism. (1) Realists are committed to the classical rules for negation. But (2) legitimate rules of inference must conserve evidence. And (3) the classical rules for negation do not conserve evidence. So (4) realism is wrong. Most realists reject 2. But it has recently been argued that if we allow denied sentences as premisses and conclusions in inferences we will be able to reject 3. And this new argument against 3 generates a new response to the anti-realist argument: keep 1 and 2, avoiding 4 by rejecting 3. My aim in this paper is to see how much work in the fight against anti-realism this new response can really do. I argue that there is a powerful objection to the response: 2 is in tension with the claim that denied sentences can be premisses and conclusions in inferences. But I show that, even given this objection, the new response has an important role to play.     

Two models of unawareness: comparing the object-based and the subjective-state-space approaches

This article attempts to motivate a new approach to anti-realism (or nominalism) in the philosophy of mathematics. I will explore the strongest challenges to anti-realism, based on sympathetic interpretations of our intuitions that appear to support realism. I will argue that the current anti-realistic philosophies have not yet met these challenges, and that is why they cannot convince realists. Then, I will introduce a research project for a new, truly naturalistic, and completely scientific approach to philosophy of mathematics. It belongs to anti-realism, but can meet those challenges and can perhaps convince some realists, at least those who are also naturalists.     

A Plantingian Pickle for a Darwinian Dilemma: Evolutionary Arguments Against Atheism and Normative Realism

Two of the most prominent evolutionary debunking arguments are Sharon Street's Darwinian Dilemma for Normative Realism and Alvin Plantinga's Evolutionary Argument against Atheism. In the former, Street appeals to evolutionary considerations to debunk normative realism. In the latter, Plantinga appeals to similar considerations to debunk atheism. By a careful comparison of these two arguments, I develop a new strategy to help normative realists resist Street's debunking attempt. In her Darwinian Dilemma, Street makes epistemological commitments that ultimately support Plantinga's structurally similar argument. If Street succeeds in debunking normative realism, I argue, then she also succeeds in debunking atheism. But atheism is a suppressed premise of the Darwinian Dilemma as well as a commitment of almost all normative anti‐realists. If Street's argument entails theism, then the Darwinian Dilemma is internally incoherent and should be abandoned by almost everyone. 1     

The epistemological challenge to metanormative realism: how best to understand it,and how to cope with it

Metaethical—or, more generally, metanormative—realism faces a serious epistemological challenge. Realists owe us—very roughly speaking—an account of how it is that we can have epistemic access to the normative truths about which they are realists. This much is, it seems, uncontroversial among metaethicists, myself included. But this is as far as the agreement goes, for it is not clear—nor uncontroversial—how best to understand the challenge, what the best realist way of coping with it is, and how successful this attempt is. In this paper I try, first, to present the challenge in its strongest version, and second, to show how realists—indeed, robust realists—can cope with it. The strongest version of the challenge is, I argue, that of explaining the correlation between our normative beliefs and the independent normative truths. And I suggest an evolutionary explanation (of a pre-established harmony kind) as a way of solving it.     

Meta‐normative Realism,Evolution, and Our Reasons to Survive

In this article, I articulate and respond to an epistemological challenge to meta‐normative realism. The challenge has it that, if realism about the normative is correct, and if evolutionary forces have significantly influenced our normative judgments, then it would be a remarkable coincidence if the content of the normative facts and our normative judgments were aligned. I criticize David Enoch's recent attempt to meet this challenge, but provide an alternative response that is structurally similar. I argue that if realism is correct, then it would be remarkable if the content of our normative judgments and the normative facts were not significantly aligned.     

Faint-hearted Anti-realism and Knowability

It is often claimed that anti-realists are compelled to reject the inference of the knowability paradox, that there are no unknown truths. I call those anti-realists who feel so compelled ‘faint-hearted’, and argue in turn that anti-realists should affirm this inference, if it is to be consistent. A major part of my strategy in defending anti-realism is to formulate an anti-realist definition of truth according to which a statement is true only if it is verified by someone, at some time. I also liberalize what is meant by a verification to allow for indirect forms of verification. From this vantage point, I examine a key objection to anti-realism, that it is committed to the necessary existence of minds, and reject a response to this problem set forth by Michael Hand. In turn I provide a more successful anti-realist response to the necessary minds problem that incorporates what I call an ‘agential’ view of verification. I conclude by considering what intellectual cost there is to being an anti-realist in the sense I am advocating.     

Wittgenstein, Dreaming and Anti-Realism: A Reply to Richard Scheer

I have argued that Wittgenstein's treatment of dreaming involves a kind of anti-realism about the past: what makes "I dreamed p " true is, roughly, that I wake with the feeling or impression of having dreamed p . Richard Scheer raises three objections. First, that the texts do not support my interpretation. Second, that the anti-realist view of dreaming does not make sense, so cannot be Wittgenstein's view. Third, that the anti-realist view leaves it a mystery why someone who reports having dreamed such-and-such is inclined to report what she does. The Reply defends my reading of Wittgenstein against these objections.     

Truthmaking, metaethics, and creeping minimalism

Creeping minimalism threatens to cloud the distinction between realist and anti-realist metaethical views. When anti-realist views equip themselves with minimalist theories of truth and other semantic notions, they are able to take on more and more of the doctrines of realism (such as the existence of moral truths, facts, and beliefs). But then they start to look suspiciously like realist views. I suggest that creeping minimalism is a problem only if moral realism is understood primarily as a semantic doctrine. I argue that moral realism is better understood instead as a metaphysical doctrine. As a result, we can usefully regiment the metaethical debate into one about moral truthmakers: In virtue of what are moral judgments true? I show how the notion of truthmaking has been simmering just below the surface of the metaethical debate, and how it reveals one metaethical view (quasi-realism) to be a stronger contender than the others.     

Pessimistic Inductions: Four Varieties

The pessimistic induction (PI) plays an important role in the contemporary realism/anti-realism debate in philosophy of science. But there is some disagreement about the structure and aim of the argument. And a number of scholars have noted that there is more than one type of PI in the philosophical literature. I review four different versions of the PI. I aim to show that PIs have been appealed to by philosophers of science for a variety of reasons. Even some realists have appealed to a PI. My goal is to advance our understanding of (1) what the various PIs can teach us about science and (2) the threat posed by PIs to scientific realism.     

Rea’s Revenge and the Persistent Problem of Persistence for Realism

Realism about material objects faces a variety of epistemological objections. Recently, however, some realists have offered new accounts in response to these long-standing objections; many of which seem plausible. In this paper, I raise a new objection against realism vis-à-vis how we could empirically come to know mind-independent essential properties for objects. Traditionally, realists hold kind-membership and persistence as bound together for purposes of tracing out an object’s essential existence conditions. But I propose kind-membership and persistence for objects can conceptually come apart and function epistemologically distinctly from one another—in which case the usual reliance by realists on an assumption of persistence to determine kind-membership conditions is unjustified. Thus, present realist attempts to explain how empirical detection of mind-independent essential properties for objects could possibly occur inevitably results in circularity. The charge against the realist is to explain why we don’t have to first discover persistence conditions for an object before we can ascertain kind-membership conditions for an object. If no answer is forthcoming, then it seems the weight of the epistemological objection to realism is back in full force.     

What Anit-realist Intuitionism Could Not Be

One of the two major parts of Dummett’s defense of intuitionism is the rejection of classical in favor of intuitionistic reasoning in mathematics, given that mathematical discourse is anti-realist. While there have been illuminating discussions of what Dummett’s argument for this might be, no consensus seems to have emerged about its overall form. In this paper I give an account of this form, starting by investigating a fundamental, but little discussed question: to what view of the relation between deductive principles and meaning is anti-realism committed? The result of this investigation is a constraint on meaning theoretic assessments of logical laws. Given this constraint, I show that, surprisingly, a consistent anti-realist critique of classical logic could not rely on the rejection of bivalence. Moreover, a consistent anti-realist defense of intuitionism must begin with a radical rejection of the very conception of logical consequence that underlies realist classical logic. It follows from these conclusions that anti-realist intuitionism seems committed to proceeding by proof theoretic means.     

Temporal Fictionalism for a Timeless World

Current debate in the metaphysics of time ordinarily assumes that we should be realists about time. Recently, however, a number of physicists and philosophers of physics have proposed that time will play no role in a completed theory of quantum gravity. This paper defends fictionalism about temporal thought, on the supposition that our world is timeless. We argue that, in the face of timeless physical theories, realism about temporal thought is unsustainable: some kind of anti-realism must be adopted. We go on to provide an argument against eliminativism about temporal thought. While it doesn't follow from this argument that fictionalism about temporal thought is true, we suggest that this nonetheless shows that fictionalism should be regarded as the preferred view.     

RESCUING RELIGIOUS NON‐REALISM FROM CUPITT

Don Cupitt's version of religious non‐realism based as it is on linguistic constructivism, radical relativism and the view that culture forms human nature has been attacked with devastating effect by realists in the last few years. I argue that there is another strand in Cupitt's thinking, his biological naturalism, that supports a different version of religious non‐realism and that he failed to see this possibility because of his global non‐realism and commitment to the strong programme in the sociology of scientific knowledge. Cupitt's biological naturalism should have led smoothly into evolutionary psychology, which has an account of religious belief that supports a non‐realist interpretation. Evolutionary psychology shows that religious beliefs are natural, normal and about matters of the deepest significance to humans. They gain their character from the operation of evolved structures of the mind and cannot be reduced to other sorts of belief. I argue that the form of religious non‐realism that emerges from taking biological naturalism seriously has a future because it respects the nature of religious belief and seeks to build on its capacity as a unique source of meaning in people's lives. There is also enough common ground with religious realism for there to be genuine dialogue between the two.     

Mind-World Identity Theory and Semantic Realism: Haldane and Boulter on Aquinas

Stephen Boulter, in The Philosophical Quarterly , 48 (1998), pp. 504–13, attacks John Haldane's proposed account of the relationship between mind and world based on Aquinas' theory of cognition. Boulter argues against Haldane's attempt to square metaphysical realism with semantic anti-realism. I argue that even if metaphysical realism and a full-bodied semantic anti-realism may be incompatible, from the stance of the mind-world identity theory, one may nevertheless maintain metaphysical realism together with the negation of semantic realism. I suggest that this is what Haldane actually claimed, and moreover that Aquinas would have accepted it. Aquinas' analogy-based semantics enlarges the recognitional capacities of speakers, and one's capacity to recognize a fact empirically is different from one's capacity to form thoughts about a fact.     

Non-representationalist cognitive science and realism

Embodied and extended cognition is a relatively new paradigm within cognitive science that challenges the basic tenet of classical cognitive science, viz. cognition consists in building and manipulating internal representations. Some of the pioneers of embodied cognitive science have claimed that this new way of conceptualizing cognition puts pressure on epistemological and ontological realism. In this paper I will argue that such anti-realist conclusions do not follow from the basic assumptions of radical embodied cognitive science. Furthermore I will show that one can develop a form of realism that reflects rather than just accommodates the core principles of non-representationalist embodied cognitive science.     

Critical Notices

Abstract

I argue that a practice can only be taken to be one of apparent rule following if it contains a practice of policing moves within the practice. So the existence of an apparently rule‐governed practice entails the existence of, what I call, a policing practice. I then argue that this entailment cannot be reconciled with a non‐factualist construal of the policing practice. Thus non‐factualism about the policing practice is false. Factualism about the policing practice entails realism about rules. So I conclude that we ought to be realists about rules. Finally I distinguish a position which I call ultra‐realism about rules and note that this too is a casualty of the view developed here.
