A Pragmatic Case against Pragmatic Scientific Realism

Pragmatic Scientific Realism (PSR) urges us to take up the realist aim or the goal of truth although we have good reason to think that the goal can neither be attained nor approximated. While Newton-Smith thinks that pursuing what we know we cannot achieve is clearly irrational, Rescher disagrees and contends that pursuing an unreachable goal can be rational on pragmatic grounds—if in pursuing the unreachable goal one can get indirect benefits. I have blocked this attempt at providing a pragmatic justification for the realist aim of PSR on precisely the same pragmatic grounds—since there is a competing alternative to PSR, and the alternative can provide whatever indirect benefits PSR can offer while being less risky than it is, prudential reasoning favours the alternative to PSR. This undermines the pragmatic case for the realist aim of science since the instrumentalist alternative does not aim at the truth.     

Theology,Metaphysics, and Realism about Truth

This essay examines the theological grounds for rejecting metaphysics and the correspondence theory of truth, and argues that while there are good grounds for rejecting a certain kind of metaphysically oriented theology, metaphysics per se is neither objectionable nor avoidable in Christian theology. In the process, it also defends a realist conception of truth against some recent theological criticisms, and argues that a commitment to a modest version of metaphysical realism and realism about truth is not only philosophically tenable, but also theologically preferable to non‐realist views.     

Review

I argue in this paper that anyone who accepts the ontology of scientific realism can only accept a pragmatic theory of truth, i.e., a theory on which truth is what it is epistemically right to believe. But the combination of realism with such a theory of truth is a form of internal realism; therefore, a scientific realist should be an internal realist. The strategy of the paper is to argue that there is no adequate semantic or correspondence theory of truth compatible with a realist ontology, that a redundancy theory cannot account for the value of truth, and that the only kind of truth theory which can account for the value of truth, and is compatible with a realist ontology, is a pragmatic theory. The kind of truth theory I wish to defend is objective and naturalistic, and the ontology is realistic. My position is, therefore, one of objective, naturalistic realism.     

TRUTH, RELATIVISM, AND CROSSWORD PUZZLES

Abstract. Neither the correspondence nor the coherence theory of truth does justice to the truth claims made in science and theology. I propose a new definition that relates truth to solving puzzles. I claim that this definition is more adequate than either of the traditional theories and that it offers two additional benefits: first, it provides grounds for a theory regarding the relations between theology and science that may stand up better to philosophical scrutiny than does critical realism; and second, it blocks the move to relativism based on recognition of the plurality of perspectives and the historical and social conditioning of knowledge.     

A PRAGMATIC CRITIQUE OF PLURALISM IN TEXT INTERPRETATION

Abstract: I take a pragmatic approach to what interpreters do when they interpret and argue that critical pluralists have focused almost exclusively on one aspect of interpretation: the fact that it is an event taking place in a historical and cultural milieu that influences the many ways interpreters approach a given text. However, there is also in interpretation a pragmatic aspect: the fact that it is an act performed by individuals who, through the utterance of their statements, implicitly make claims, for example, regarding the truth of their interpretation. In the first part I explain what critical pluralists overlook and the consequences of such oversight. In the second part I indicate how the validity of interpretation can be assessed.     

On the Relationship between Truth and Liberal Politics

This paper examines the relationship between truth and liberal politics via the work of Bernard Williams and Richard Rorty. I argue that Williams is right to think that there are positive relations between truth, specifically a realist understanding of truth, and liberal politics that Rorty's abandonment of the realist vocabulary of truth undermines. At the heart of this concern is the worry that abandoning the realist vocabulary opens up the possibility that the standards of justification for our true beliefs can be manipulated by those with the power to do so in order to further their own political ends. The political benefit of realism is that it fixes the standards of justification and makes them immune to manipulation by the use of power. However, I suggest that there is a form of realism available that Rorty can accept which would deliver the political benefits of the realist vocabulary without requiring him to accept the thick realist metaphysics that he wants to avoid. My conclusion is that there is a positive and important relationship between truth and liberal politics, a relationship that can be sustained without any necessary commitment to realist metaphysics.     

Higher Education in Light of the Cross

What is the summum bonum of a university education? The much lauded “liberal” approach of Aristotle, Newman, and Roche proposes that education is for contemplating the truth—an intrinsic, joyous end in itself. This approach offers the benefits of pursuing truth, virtues, and intellectual habits, but it also carries with it the temptations of idealatry and homo incurvatus in se. Christian universities can reform this approach to education, though, with Luther's theology of the cross, reorienting it through the crucified Christ toward the highest ends of life revealed in God's word: faith in God and love for the neighbor.     

INTERPRETATION NEUTRALITY FOR QUANTUM THEOLOGY

Within contemporary scientific and science-adjacent communities, it is generally accepted that quantum physics is our best theory. For this reason, it is understandable—and laudable—that scholars interested in questions at the intersection of science and theology wish to meaningfully engage with this physics. Recent work in foundations of physics has, however, importantly altered the landscape of quantum theory; in this article, my goal is to introduce these advances, then make an argument within this new landscape that I hope will be useful for certain theological inquiries. Specifically, I shall argue from grounds of the physics itself that one may, with clear philosophical conscience, access the majority of quantum theory's tools, models, and explanations while maintaining an interpretation-neutral yet realist stance toward this physics.     

The Problem of Deep Competitors and the Pursuit of Epistemically Utopian Truths

According to standard scientific realism, science seeks truth and we can justifiably believe that our successful theories achieve, or at least approximate, that goal. In this paper, I discuss the implications of the following competitor thesis: Any theory we may favor has competitors such that we cannot justifiably deny that they are approximately true. After defending that thesis, I articulate three specific threats it poses for standard scientific realism; one is epistemic, the other two are axiological (that is, pertaining to the claim that science seeks truth). I also flag an additional axiological “challenge,” that of how one might justify the pursuit of a primary aim, such as truth. Bracketing epistemic realism, I argue that the axiological threats can be addressed by embracing a refined realist axiological hypothesis, one that specifies a specific subclass of true claims sought in science. And after identifying three potential responses to the axiological “challenge,” I contend that, while standard axiological realism appears to lack the resources required to utilize any of the responses, the refined realist axiology I embrace is well suited to each.     

DIRECTIONS IN HISTORICISM: LANGUAGE, EXPERIENCE, AND PRAGMATIC ADJUDICATION

Abstract. This article examines the current affirmation within theology of historicism, with its assumption that the historical realm, broadly construed, is the only arena of human activity and knowledge and its repudiation of traditional forms of foundationalism and correspondence theories of truth. The essay performs this task by analyzing the work of Gordon Kaufman and William Dean, setting forth their commonly shared historicism, pragmatism, and constructivist approaches to theology, as well as their differences concerning nonlinguistic dimensions of experience. The essay also focuses on the move by both thinkers to include nature in their understanding of history and to offer biocultural interpretations of human existence.     

Putting Pluralism in its Place

Pluralism about truth is the view that there are many properties, not just one, in virtue of which things are true. Pluralists hope to dodge the objections that face traditional monistic substantive views of truth (such as the correspondence theory), as well as those facing deflationary theories of truth. More specifically, pluralists hope to advance an explanatorily potent understanding of truth that can capture the subtleties of various realist and anti‐realist domains of discourse, all while avoiding the scope problem. I offer a new objection to pluralism that challenges its fundamental commitment to there being a set of alethic properties in virtue of which claims are true. In its place I offer an alternative view that merges standard truthmaker theory with a primitivist conception of truth. This combination of views satisfies the theoretical desires that pluralists claim for themselves, but without taking on pluralism's host of challenges and problems.     

THE LIMITS OF PRAGMATISM AND THE LIMITS OF REALISM

Abstract. I argue here for a limited version of pragmatism—called conceptual pragmatism—that recognizes that conceptual systems are to be evaluated according to their usefulness for helping us get around in the world. Once a conceptual system is in place, however, the truth of sentences is a matter of both empirical tit and coherence with the rest of our knowledge. The error of critical realists is to fail to take into account the limited conceptual relativity that is to be expected on the basis of conceptual pragmatism. The conceptual realist thesis applies equally in science and theology.     

Modeling without representation

How can mathematical models which represent the causal structure of the world incompletely or incorrectly have any scientific value? I argue that this apparent puzzle is an artifact of a realist emphasis on representation in the philosophy of modeling. I offer an alternative, pragmatic methodology of modeling, inspired by classic papers by modelers themselves. The crux of the view is that models developed for purposes other than explanation may be justified without reference to their representational properties.     

The Trouble with Harrison's 'The Trouble with Tarski'

In 'The Trouble with Tarski', The Philosophical Quarterly , 48 (1998), pp. 1–22, Jonathan Harrison attacks 'Tarski-style' truth theories for both formalized and natural languages, on the grounds that (1) truth cannot be a property of sentences; (2) if it could be, T-sentences would have to be necessary truths, which they are not; and (3) T-sentences are not necessarily true and can even can be false. I reply that (1) cannot be an objection to Tarskian truth theories, since these can be formulated in terms of whatever truth bearers might be. Thesis (2) is unjustified: Harrison's argument for it depends on an equivocation. Thesis (3) is false, since the right-hand side of a T-sentence is a meta-language translation of the object-language sentence described on the left-hand side, and this guarantees its truth.

Philosophical Hermeneutics and Theological Education

This article explores the resources that the philosophical hermeneutics of Hans‐Georg Gadamer can bring to the challenge of teaching theology to undergraduates. The author offers a sympathetic reading of Gadamer but is influenced by the insights of liberation theology. In this interpretation of his work, Gadamer's contribution lies in his emphases on intersubjectivity and on praxis as the goal of historically conscious understanding — and thus of historically conscious theological education. To suggest what philosophical hermeneutics can tell us about the process of teaching and learning in theology, this essay examines Gadamer's approach to historicity, conversation, truth, objectivity, subjectivity, practical wisdom, and praxis.     

In Defence of a Structural Account of Indirect Realism

Current orthodoxy in the philosophy of perception views indirect realism as misguided, wrongheaded or simply outdated. The reasons for its pariah status are variegated. Although it is surely not unreasonable to speculate that philosophical fashion is one factor that contributes to this situation, there are also solid philosophical arguments which put pressure on the indirect realist position. In this paper, I will discuss one such main objection and show how the indirect realist can face it. The upshot will be a defence of a new structural account of indirect realism which is immune to a number of objections that have been traditionally levelled at such theories of perceptual consciousness.     

Success and truth in the realism/anti-realism debate

I aim to clarify the relationship between the success of a theory and the truth of that theory. This has been a central issue in the debates between realists and anti-realists. Realists assume that success is a reliable indicator of truth, but the details about the respects in which success is a reliable indicator or test of truth have been largely left to our intuitions. Lewis (Synthese 129:371–380, 2001) provides a clear proposal of how success and truth might be connected, comparing a test of success of our theories to medical tests with low rates of false positives and false negatives. But, contrary to what Lewis claims, I argue that it is not enough for the realist to undercut the claim that success is not a reliable indicator of truth. Rather, the realist must show that our current best theories are likely true. Further, I argue that tests in science are unlike medical tests in a number of important ways.     

Kuhn as Perspectival Realist

In this essay I argue that T. S. Kuhn, at least in his later works, can be regarded as a perspectival realist. This is a retrospective interpretation based mainly on the essays published posthumously under the title The Road Since Structure (Kuhn 2000). Among the strongest grounds for this interpretation is that Kuhn explicitly states that one must have a “lexicon” in place before raising questions about the truth or falsity of claims made using elements of the lexicon. This, in a linguistic framework, can be understood as an affirmation of perspectival realism. The essay concludes with an examination of Donald Davidson’s famous paper, “On The Very Idea of a Conceptual Scheme,” arguing, along lines Kuhn himself suggested, that Davidson’s presentation is no threat to his notion of a conceptual scheme, or, I would add, a theoretical perspective.     

Ideal Epistemic Situations and the Accessibility of Realist Truth

There is a widespread opinion that the realist idea that whether a proposition is true or false typically depends on how things are independently of ourselves is bound to turn truth, in Davidson's words, into something to which humans can never legitimately aspire. This opinion accounts for the ongoing popularity of epistemic theories of truth, that is, of those theories that explain what it is for a proposition (or statement, or sentence, or what have you) to be true or false in terms of some epistemic notion, such as provability, justifiability, verifiability, rational acceptability, warranted assertibility, and so forth, in some suitably characterized epistemic situation. My aim in this paper is to show that the widespread opinion is erroneous and that the (legitimate) epistemological preoccupation with the accessibility of truth does not warrant the rejection of the realist intuition that truth is, at least for certain types of propositions, radically nonepistemic.
