- Berit Brogaard & Joe Salerno (2005). Antirealism, Theism and the Conditional Fallacy. Noûs 39 (1):123–139.In his presidential address to the APA, ‘‘How to be an Anti-realist’’ (1982, 64–66), Alvin Plantinga argues that the only sensible way to be an antirealist is to be a theist.1 Anti-realism (AR) in this context is the epistemic analysis of truth that says, (AR) necessarily, a statement is true if and only if it would be believed by an ideally [or sufficiently] rational agent/community in ideal [or sufficiently good] epistemic circumstances. Plantinga demonstrates, with modest modal resources, that AR entails that necessarily, ideal epistemic circumstances obtain. It is a contingent matter whether ideal epistemic circumstances obtain for worldly agents and communities. Hence, the lesson, according to Plantinga, is that an anti-realist should be a theist. In the present paper we evaluate whether anti-realism entails that necessarily ideal epistemic circumstances obtain. A more careful analysis of Plantinga’s argument appears in section 1. We notice that Plantinga’s interpretation of anti-realism harbors an ambiguity of quantifier scope and that only on the less plausible placement of the quantifiers does AR obviously entail that necessarily ideal epistemic circumstances obtain. In section 2 we evaluate an alternative version of Plantinga’s argument developed by Michael Rea. Rea’s argument gets the quantifiers straight, but depends on logical resources that the anti-realist has independent reason to reject. After evaluating Rea’s argument we conclude that an anti-realist need not be a theist and is not committed to the necessary existence of..No categoriesReading list | Discuss | Edit | Categorize |My bibliography

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.

The thesis focuses on what impact the use of idealizations has on the realism/anti-realism debate concerning the fundamental laws of physics. My aim is modest. It is not to present an argument for either the realist or the anti-realist position but rather to show where the debate stands once we have considered recent arguments by Laymon and Cartwright which have made use of the notion of idealization assumptions. My intent is to point out the difficulties of Laymon's argument for realism in the hope of showing what must be accomplished in providing a more convincing argument for realism. I will also suggest that although Laymon's proposal is problematic, it still poses a serious problem for van Fraassen's form of anti-realism, constructive empiricism.

(1) Given materialism, the conditional probability of the reliability of human cognitive mechanisms produced by evolution is low; (2) the same conditional probability given reductive or non-reductive materialism is still low; (3) the most popular naturalistic theories of content and truth are not admissible for naturalism. I argue that Plantinga’s argument for (1) presupposes an anti-materialistic conception of content, and it therefore begs the question against materialism. To argue for (2), Plantinga claims that the adaptiveness of a belief is indifferent to its truth. I argue that this claim is unsupported unless it again assumes an anti-materialistic conception of content and truth. I further argue that Plantinga’s argument for (3) is not successful either, because an improved version of teleosemantics can meet his criticisms. Moreover, this version of teleosemantics implies that the truth of a belief is (probabilistically) positively related to its adaptiveness, at least for simple beliefs about physical objects in human environments. This directly challenges Plantinga’s claim that adaptiveness is indifferent to truth.

Michael Dummett’s realism debate is a semantic dispute about the kind of truth conditions had by a given class of sentences. According to his semantic realist, the truth conditions are potentially verification-transcendent in that they may obtain (or not) despite the fact that we may be forever unable to recognize whether they obtain. According to Dummett’s semantic anti-realist, the truth conditions are of a different sort. Essentially, for the anti-realist, that the truth conditions obtain (whenever they do) is a matter that is always recognizable by us in principle. On this view, truth cannot outrun all possible human knowledge. Unsurprisingly, the outcome of the debate is sometimes said to hinge on whether all truths are knowable.1 More carefully the point of contention is the following..

In Language, Logic, and Experience, Michael Luntley successfully employs a Kantian-style transcendental argument to refute Michael Dummett’s anti-realist view that we are incapable of grasping “recognition-transcendent” truth-conditions. But he also contends that his own purified version of antirealism is immune to thi s sort of attack. This version is purified because it is concerned solely with the question of whether a given statement possesses a determinate truth value, and thus with whether the reality it is about exists determinately. I show that Kant’s original version of the argument (in the “Transcendental Analytic”) does in fact amount to a refutation of Luntleyan anti-realism. In particular, it demonstrates that the determinate existence of all past and present naturalistic states and events is a necessary condition of thought. Since Luntleyan anti-realism entails that many such states and events are indeterminate, it must be rejected.

This critical survey of recent work on Kant's doctrine of the fact of reason and his doctrine of the practical postulates (of freedom, God, and immortality) assesses the implications of these doctrines for the debate about realism and antirealism in Kant's moral philosophy. Section 1 briefly surveys some salient considerations from the first Critique and Groundwork. In section 2, I argue that recent work on the role, content, "factual" nature, and epistemic status of the fact of reason does not support an anti-realist interpretation of Kant's ethics. In section 3, I argue that recent work on the derivation and epistemic and ontological status of the practical postulates does not support an anti-realist interpretation of Kant's ethics.

This paper examines Alvin Plantinga's defence of theistic belief in the light of Paul Draper's formulation of the problem of evil. Draper argues (a) that the facts concerning the distribution of pain and pleasure in the world are better explained by a hypothesis which does not include the existence of God than by a hypothesis which does; and (b) that this provides an epistemic challenge to theists. Plantinga counters that a theist could accept (a) yet still rationally maintain a belief in God. His defence of theism depends on the epistemic value of religious experience. I argue, however, that Plantinga's defence of theism is not successful.

I argue that Fitch’s ‘paradox of knowability’ presents no special problem for the epistemic anti-realist who believes that reality is epistemically accessible to us. For the claim which is the target of the argument (If p then it is possible to know p) is not a commitment of anti-realism. The epistemic anti-realist’s commitment is (or should be) to the recognizability of the states of affairs which render true propositions true, not to the knowability of the propositions themselves. A formal apparatus for discussing the recognizability of states of affairs is offered, and other prima facie similar approaches to the paradox argument are reviewed.

Since each side in the debate has its disadvantages, it is tempting to try to combine realist theses with anti-realist theses in order to obtain a better, more moderate position. Putnam attempts to hold a realist concept of truth, yet he rejects realist metaphysics and realist semantics. He calls this view internal realism. Truth is realist on this picture for it is objective, rather than merely intersubjective, and eternal. Putnam introduces a concept of epistemic idealization — epistemically ideal conditions, or idealized justification — to try to ground the strong objectivity of truth without sliding into metaphysical realism. I argue that the concept of ideal conditions to which Putnam appeals does not cohere with his (anti-realist) commitment to an assertability conditions account of meaning.

Brogaard and Salerno (2005, Nous, 39, 123–139) have argued that antirealism resting on a counterfactual analysis of truth is flawed because it commits a conditional fallacy by entailing the absurdity that there is necessarily an epistemic agent. Brogaard and Salerno's argument relies on a formal proof built upon the criticism of two parallel proofs given by Plantinga (1982, "Proceedings and Addresses of the American Philosophical Association", 56, 47–70) and Rea (2000, "Nours," 34, 291–301). If this argument were conclusive, antirealism resting on a counterfactual analysis of truth should probably be abandoned. I argue however that the antirealist is not committed to a controversial reading of counterfactuals presupposed in Brogaard and Salerno's proof, and that the antirealist can in principle adopt an alternative reading that makes this proof invalid. My conclusion is that no reductio of antirealism resting on a counterfactual analysis of truth has yet been provided.
