Marton ( 2019 ) argues that that it follows from the standard antirealist theory of truth, which states that truth and possible knowledge are equivalent, that knowing possibilities is equivalent to the possibility of knowing, whereas these notions should be distinct. Moreover, he argues that the usual strategies of dealing with the Church–Fitch paradox of knowability are either not able to deal with his modal-epistemic collapse result or they only do so at a high price. Against this, I argue (...) that Marton’s paper does not present any seriously novel challenge to anti-realism not already found in the Church–Fitch result. Furthermore, Edgington ( 1985 ) reformulated antirealist theory of truth can deal with his modal-epistemic collapse argument at no cost. (shrink)

The central aim of this article is to argue that Nietzsche takes his own taste, and those in the relevant sense similar to it, to enjoy a kind of epistemic privilege over their rivals. Section 2 will examine the textual evidence for an anti-realist reading of Nietzsche on taste. Section 3 will then provide an account of taste as an ‘affective evaluative sensibility’, asking whether taste so understood supports an anti-realist reading. I will argue that it does (...) not and that we should resist construing the affects, which constitute taste for Nietzsche, as no more than Humean subjective preferences. Section 4 will then consider passages in which Nietzsche makes a connection between taste and epistemic considerations, suggesting that he appears to situate the epistemic privilege of his taste in a more fundamental method of evaluative disclosure, namely pre-reflective affective responses. Finally, Section 5 will argue that we can make sense of how such affective responses could provide us with evaluative knowledge by narrowing the scope of the objects of Nietzsche’s taste to other affective-evaluative states, such that the affective responses are meta-affective evaluations. On the basis of this idea, I construct a theory of meta-affective responses providing their subjects with access to the intrinsic phenomenal value of other affective-evaluative states, and then go on to show how Nietzsche can be read as applying this theory in a number of passages.

The debate between scientific realism and anti-realism remains at a stalemate, making reconciliation seem hopeless. Yet, important work remains: exploring a common ground, even if only to uncover deeper points of disagreement and, ideally, to benefit both sides of the debate. I propose such a common ground. Specifically, many anti-realists, such as instrumentalists, have yet to seriously engage with Sober's call to justify their preferred version of Ockham's razor through a positive account. Meanwhile, realists face a (...) similar challenge: providing a non-circular explanation of how their version of Ockham's razor connects to truth. The common ground I propose addresses these challenges for both sides; the key is to leverage the idea that everyone values some truths and to draw on insights from scientific fields that study scientific inference—namely, statistics and machine learning. This common ground also isolates a distinctively epistemic root of the irreconcilability in the realism debate. (shrink)

Epistemic theories of truth, such as those presumed to be typical for anti-realism, can be characterised as saying that what is true can be known in principle: p → ◊Kp. However, with statements of the form “p & ¬Kp”, a contradiction arises if they are both true and known. Analysis of the nature of the paradox shows that such statements refute epistemic theories of truth only if the the anti-realist motivation for epistemic theories of (...) truth is not taken into account. The motivation in a link of understandability ans meaningful- ness suggests to change the above principle and to restrict the theory to logically simple sentences, in which case the paradox does not arise. This suggestion also allows to see the deep philosophical problems for anti-realism those counterexamples are pointing at. (shrink)

Allan Hazlett has recently developed an alternative to the most popular form of anti-realism about epistemic normativity, epistemic expressivism. He calls it “convention-relativism about epistemic discourse”. The view deserves more attention. In this paper, I give it attention in the form of an objection. Specifically, my objection turns on a distinction between inescapable and categorical norms. While I agree with Hazlett that convention-relativism is consistent with inescapable epistemic norms, I argue that it is not (...) consistent with categorical epistemic norms. I then argue that Hazlett's account of a controversial upshot of convention-relativism – namely, that epistemic discourse is not “normative” – should, but does not, adequately address the question of whether epistemic norms are categorical. This leads to a more general discussion of anti-realism in epistemology. (shrink)

This paper attempts to delineate a kind of realism, which incorporates some anti-realistic insights regarding the perspective, situated, and historical character of our forms of knowing and being in the world, and which resonates with the basic tenets of Christian theism. The first part of the paper analyzes the challenges anti-realism poses to Christian theism, particularly regarding the role, which the doctrine of creation played in securing the correspondence theory of truth as well as the fundamental (...) experience of God as the foundation of order and meaning. Using Heidegger’s hermeneutics in the second part, it is shown that epistemic pluralism can be made compatible with realism. Given that this form of hermeneutic realism still has problems with integrating the transcendence of God, as well as his/ her presence and action in the “world,” the notion of continuous co-creation as the basis for a pluralist realism that is amenable to Christian theism is explored in the final part.

What is the relation between method and truth? Are we justified in accepting a theory that satisfies the rules of scientific method as true? Such questions divide realism from anti-realism in the philosophy of science. Scientific realists take the methods of science to promote the realist aim of correspondence truth. Anti-realists either claim that the methods of science promote lesser epistemic goals than realist truth, or else they reject the realist conception of truth altogether. In (...) this paper, I propose a realist theory of the relation between method and truth. The theory consists of three basic elements: (a) a naturalistic treatment of epistemic normativity, (b) an instrumentalist conception of the nature of methodological rules, and (c) an abductive argument for the truth-conduciveness of the rules of scientific method.

Philosophers of science often assume that logically equivalent theories are theoretically equivalent. I argue that two theses, anti-exceptionalism about logic (which says, roughly, that logic is not a priori, that it is revisable, and that it is not special or set apart from other human inquiry) and logical realism (which says, roughly, that differences in logic reflect genuine metaphysical differences in the world), make trouble for both this commitment and the closely related commitment to theories being closed under (...) logical consequence. I provide three arguments. The first two show that anti-exceptionalism about logic provides an epistemic challenge to both the closure and the equivalence claims; the third shows that logical realism provides a metaphysical challenge to both the closure and the equivalence claims. Along the way, I show that there are important methodological upshots for metaphysicians and philosophers of logic. In particular, there are lessons to be drawn about certain conceptions of naturalism as constraining the possibilities for metaphysics and the philosophy of logic. (shrink)

In this article, against the background of a notion of ‘assembled’ truth, the evolutionary progressiveness of a theory is suggested as novel and promising explanation for the success of science. A new version of realism in science, referred to as ‘naturalised realism’ is outlined. Naturalised realism is ‘fallibilist’ in the unique sense that it captures and mimics the self-corrective core of scientific knowledge and its progress. It is argued that naturalised realism disarms Kyle Stanford’s anti-realist (...) ‘new induction’ threats by showing that ‘explanationism’ and his ‘epistemic instrumentalism’ are just two positions among many on a constantly evolving continuum of options between instrumentalism and full-blown realism. In particular it is demonstrated that not only can naturalised realism redefine the terms of realist debate in such a way that no talk of miracles need enter the debate, but it also promises interesting defenses against inductive- and under-determination-based anti-realist arguments.

In this paper, I discuss a new problem for moral realism, the problem of moral aliens. In the first section, I introduce this problem. Moral aliens are people who radically disagree with us concerning moral matters. Moral aliens are neither obviously incoherent nor do they seem to lack rational support from their own perspective. On the one hand, moral realists claim that we should stick to our guns when we encounter moral aliens. On the other hand, moral realists, in (...) contrast to anti-realists, seem to be committed to an epistemic symmetry between us and our moral aliens that forces us into rational suspension of our moral beliefs. Unless one disputes the very possibility of moral aliens, this poses a severe challenge to the moral realist. In the second section, I will address this problem. It will turn out that, on closer scrutiny, we cannot make any sense of the idea that moral aliens should be taken as our epistemic peers. Consequently, there is no way to argue that encountering moral aliens gives us any reason to revise our moral beliefs. If my argument is correct, the possibility of encountering moral aliens poses no real threat to moral realism. (shrink)

Several anti-debunkers have argued that evolutionary explanations of our moral beliefs fail to meet a necessary condition on undermining defeat called modal security. They conclude that evolution, therefore, does not debunk our moral beliefs. This article shows that modal security is false if knowledge is virtuous achievement. New information can undermine a given belief without providing reason to doubt that that belief is sensitive or safe. This leads to a novel conception of undermining defeat, and it shows that successful (...) debunking of moral realism is possible. (shrink)

As is well known, Putnam changed his philosophical position on a number of occasions throughout his career. In this paper, I reconsider the position of internal realism which Putnam defended from the mid-1970’s until around 1990. The paper opens with a discussion of the position that Putnam called “metaphysical realism”, since his internal realism emerged out of a critique of that position. The paper then briefly presents the internal realist view as one which involves an epistemic (...) conception of truth, as well as an anti-realist metaphysical outlook on which objects depend on conceptual scheme. The paper then provides a survey of the key objections to internal realism which emerged in the ensuing debate with defenders of realism. The paper concludes with a brief consideration of the relevance of Putnam’s later adoption of a direct realist theory of perception with respect to the issue of realism. (shrink)

Simon Blackburn, in Truth A Guide for the Perplexed (Blackburn 2006), deploys the relation of thought with the facts and says, ‘We met the argument that theorizing involves an impossible activity of stepping outside our own skins and pretending to a ‘transcendental’ point of view, a standpoint from which we can survey the relationship between our thoughts and facts, without using the very forms of thought whose relation to the facts we are hoping to describe.’ (Blackburn, 2006, 109). My philosophical (...) reflections on this claim appreciate the view and turn towards the epistemic semblance in the metaphysical purview. A few challenges of the theory take up a side-effect of the ‘knowing procedures’ and its subsequent notion of the rigid concomitance of realism without a human face. My endeavor would be to slightly bypass the account of objective realism and debut into the sphere of the old-fashioned query, ‘what do we know about the conceptualized world where concepts steadily contaminate objects?’ We may appreciative beliefs and concepts, which are human creations, as these impart to the human-experienced world where concepts are the objective features of the subject’s conceptual scheme.

Autologos. A dialogue on fundamental logic. - In this dialogue of three dialogue partners, an attempt is made to prove the logical prerequisites of any meaningful dialogue by using transcendental arguments. Among these inescapable logical premises are a semantics as strong as that of modal logic S5, and an epistemic anti-realism.

Consider the claim that openmindedness is an epistemic virtue, the claim that true belief is epistemically valuable, and the claim that one epistemically ought to cleave to one’s evidence. These are examples of what I’ll call “ epistemic discourse.” In this paper I’ll propose and defend a view called “convention-relativism about epistemic discourse.” In particular, I’ll argue that convention-relativismis superior to its main rival, expressivism about epistemic discourse. Expressivism and conventionalism both jibe with anti-realism (...) about epistemic normativity, which is motivated by appeal to philosophical naturalism. Convention-relativism says that epistemic discourse describes how things stands relative to a conventional set of “ epistemic ” values; such discourse is akin to normative discourse relative to the conventional rules of a club. I defend conventionalism by appeal to a “reverse open question argument,” which says, pace expressivism, that epistemic discourse leaves the relevant normative questions open. (shrink)

Wright's _Truth and Objectivity_ seeks to systematise a variety of anti-realist positions. I argue that many objections to the system are avoided by transposing its talk of truth into talk of warrant. However, a problem remains about debates involving 'direction-of-fit'. -/- Dummett introduced 'anti-realism' as a philosophical view informed by mathematical intuitionism. Subsequently, the term has been associated with many debates, ancient and modern. _Truth and Objectivity_ proposes that truth admits of different characteristics; these various debates then (...) concern which characteristics truth has, in a given area. This pluralism of truth is at odds with deflationism. I find fault with Wright's argument against deflationism. However, transmission of warrant across the Disquotational Schema suffices to ground Wright's proposal, which survives as a pluralism of classes of warrant. -/- The two main debates concern whether truths are always knowable (Epistemic Constraint) and whether disagreements in an area must be down to some fault of one of those involved (Cognitive Command). I introduce Assertoric Constraint, relating to Epistemic Constraint, where truths cannot outstrip the availability of warrant for their assertion. I solve a structural problem by a comparison with a constitutive analysis of Moore's Paradox. The relativism of blameless disagreement is problematic. Wright's response invokes a sort of ignorance which he calls `Quandary'. I criticise this before proposing an alternative. -/- I agree with Wright that Dummett's original anti-realism does not belong among the positions which Wright seeks to systematise. However, two candidates show that the proposal suffers a weakness. Wright thinks Expressivism misguided, and implicitly rules out his earlier non-cognitivism about necessity. I argue that Expressivism has promise, and I endorse Wright's Cautious Man argument for non-cognitivism about necessity; both involve play with `direction-of-fit'. I conclude that this sort of anti-realist debate needs to be accommodated by the proposal. (shrink)

The paper proposes a synthesis between human scientists and artificial representation learning models as a way of augmenting epistemic warrants of realist theories against various anti-realist attempts. Towards this end, the paper fleshes out unconceived alternatives not as a critique of scientific realism but rather a reinforcement, as it rejects the retrospective interpretations of scientific progress, which brought about the problem of alternatives in the first place. By utilising adversarial machine learning, the synthesis explores possibility spaces of (...) available evidence for unconceived alternatives providing modal knowledge of what is possible therein. As a result, the epistemic warrant of synthesised realist theories should emerge bolstered as the underdetermination by available evidence gets reduced. While shifting the realist commitment away from theoretical artefacts towards modalities of the possibility spaces, the synthesis comes out as a kind of perspectival modelling. (shrink)

This book offers a ground-up defense of objective morality, drawing inspiration from a wide range of philosophers, including John Locke, Arthur Schopenhauer, Iris Murdoch, Nel Noddings, and David Lewis. The core claim is compassion is our capacity to perceive other creatures' pains, pleasures, and desires. Non-compassionate people are therefore perceptually lacking, regardless of how much factual knowledge they might have. Marshall argues that people who do have this form of compassion thereby fit a familiar paradigm of moral goodness. His argument (...) involves the identification of an epistemic good which Marshall dubs "being in touch". To be in touch with some property of a thing requires experiencing it in a way that reveals that property - that is, experiencing it as it is in itself. Only compassion, Marshall argues, lets us be in touch with others' motivational mental properties. -/- This conclusion about compassion has two important metaethical consequences. First, it generates an answer to the question ";Why be moral?", which has been a central philosophical concern since Plato. Second, it provides the keystone for a novel form of moral realism. This form of moral realism has a distinctive set of virtues: it is anti-relativist, naturalist, and able to identify a necessary connection between moral representation and motivation. The view also implies that there is an epistemic asymmetry between virtuous and vicious agents, according to which only morally good people can fully face reality. (shrink)

In this paper, I reconstruct the development and the complex character of Zilsel’s conception of scientific laws. This concept functions as a fil rouge for understanding Zilsel’s philosophy throughout different times (here, the focus is on his Viennese writings and how they pave the way to the more renown American ones) and across his many fields of work (from physics to politics). A good decade before Heisenberg’s uncertainty principle was going to mark the outbreak of indeterminism in quantum physics, Edgar (...) Zilsel started to develop a complex logical-philosophical theory in which statistical and causal laws were given an indeterministic foundation (Zilsel 1916). However, in developing his thoughts on the emergence of regularities from disorder, Zilsel arrives at a profound ambiguity with respect to the ontological or the epistemic nature of laws and order in the world: Whether this order is to be conceived of as an empirical finding or as the product of reason – this would have to remain unclear. This tension between rationalism and empiricism, as well as a tension between a realist and an anti-realist conception of lawfulness, can be identified in both Zilsel’s Viennese and American writings: a tension which touches the core of the “application problem” that would keep haunting Zilsel until his premature death.

Fitch's knowability paradox shows that for each unknown truth there is also an unknowable truth, a result which has been thought both odd in itself and at odds with views which impose epistemic constraints on truth and/or meaningfulness. Here a solution is considered which has received little attention in the debate but which carries prima facie plausibility. The decidability solution is to accept that Fitch sentences are unknowably true but deny the significance of this on the grounds that Fitch (...) sentences are nevertheless decidable. The decidability solution is particularly attractive for those whose primary concern is an epistemic constraint on meaningfulness (‘verificationists’). For those whose main concern is truth (‘anti-realists’), the situation is more complex: Melia takes the solution to exonerate anti-realism completely; Williamson sees it as completely irrelevant. The truth lies between these two extremes: there is one broad anti-realist commitment to which the solution does not apply, but there is also one, the “fundamental tenet” of anti-realism according to Dummett, to which it does. (shrink)

A novel solution to the knowability paradox is proposed based on Kant’s transcendental epistemology. The ‘paradox’ refers to a simple argument from the moderate claim that all truths are knowable to the extreme claim that all truths are known. It is significant because anti-realists have wanted to maintain knowability but reject omniscience. The core of the proposed solution is to concede realism about epistemic statements while maintaining anti-realism about non-epistemic statements. Transcendental epistemology supports such (...) a view by providing for a sharp distinction between how we come to understand and apply epistemic versus non-epistemic concepts, the former through our capacity for a special kind of reflective self-knowledge Kant calls ‘transcendental apperception’. The proposal is a version of restriction strategy: it solves the paradox by restricting the anti-realist’s knowability principle. Restriction strategies have been a common response to the paradox but previous versions face serious difficulties: either they result in a knowability principle too weak to do the work anti-realists want it to, or they succumb to modified forms of the paradox, or they are ad hoc. It is argued that restricting knowability to non-epistemic statements by conceding realism about epistemic statements avoids all versions of the paradox, leaves enough for the anti-realist attack on classical logic, and, with the help of transcendental epistemology, is principled in a way that remains compatible with a thoroughly anti-realist outlook.

In her book Extended Rationality: A Hinge Epistemology (2015), Annalisa Coliva puts forward an anti-sceptical proposal based on the idea that the notion of rationality extends to the unwarrantable presuppositions “that make the acquisition of perceptual warrants possible” (2015: 150). These presuppositions are commonly the target of sceptical arguments, and by showing that they are on the one hand unwarrantable, but on the other are constitutive components of rationality itself, she reveals that they are beyond rational doubt and thus (...) avoids scepticism. Part of Coliva’s defence of using extended rationality in this way involves distancing it from relativist interpretations, which she describes as “devastating” (2015: 120). She proposes two ways that someone might attempt to formulate epistemic relativism from her extended rationality view, and argues that both would be unsuccessful because they require describing alternative conceptions of rationality which are “unintelligible” (in the first case), or “inconceivable” (in the second). The superficial claim of this chapter is that Coliva’s arguments, as they stand, are insufficient to dismiss relativism. She fails to show that the conception of rationality needed for the first formulation of relativism is unintelligible, and overestimates the significance of the second formulation’s conception turning out to be inconceivable. But I also highlight a deeper problem: neither formulation follows a realistic blueprint for relativism, and so these were the wrong possibilities to consider in the first place. To address this issue, I propose a third, more plausible, way in which someone might attempt to formulate relativism on the basis of Coliva’s account. I leave open whether this strategy is successful, or whether a version of Coliva’s criticisms apply to it too. (shrink)

God's necessary existence makes sense. Attempt at a transcendental modal proof. - In this essay I outline a novel three-stage proof of God's necessary existence using transcendental and deductive methods. In the first step of the proof, by retorsion, it is proved that there is at least one sentence that is necessary and inescapable. In the second step, the inescapability of the modal logic supposed in the proof is shown. This step also contains a new argument in favour of (...) class='Hi'>epistemic anti-realism. The third step finally proves the necessary existence of the person who proves. The proof thus refers to the subject, the object, and the method of this proof itself. (shrink)

Reflectivists consider reflective reasoning crucial for good judgment and action. Anti-reflectivists deny that reflection delivers what reflectivists seek. Alas, the evidence is mixed. So, does reflection confer normative value or not? This paper argues for a middle way: reflection can confer normative value, but its ability to do this is bound by such factors as what we might call epistemic identity: an identity that involves particular beliefs—for example, religious and political identities. We may reflectively defend our identities’ beliefs (...) rather than reflect open-mindedly to adopt whatever beliefs cohere with the best arguments and evidence. This bounded reflectivism is explicated with an algorithmic model of reflection synthesized from philosophy and science that yields testable predictions, psychometric implications, and realistic metaphilosophical suggestions—for example, overcoming motivated reflection may require embracing epistemic identity rather than veiling it (à la Rawls 1971). So bounded reflectivism should be preferred to views offering anything less. (shrink)

> Context • The alleged dichotomy between mind and matter is pervasive. Therefore, the attempt to explain mat- ter in terms of mind (idealism) is often considered a mirror image of that of explaining mind in terms of mat- ter (mainstream physicalism), in the sense of being structurally equivalent despite being reversely arranged. > Problem • I argue that this is an error arising from language artifacts, for dichotomies must reside in the same level of abstraction. > Method • I (...) show that, because matter outside mind is not an empirical observation but rather an explanatory model, the epistemic symmetry between the two is broken. Consequently, matter and mind cannot reside in the same level of abstraction. > Results • It then becomes clear that attempting to explain mind in terms of matter is epistemically more costly than attempting to explain matter in terms of mind. > Implications • The qualities of experience are suggested to be not only epistemically, but also ontologically primary. > Constructivist content • I high- light the primacy of perceptual constructs over explanatory abstraction on both epistemic and ontic levels. > Key words • Idealism, physicalism, pancomputationalism, anti-realism, hard problem of consciousness, epistemic symmetry, explanatory abstraction, levels of abstraction.

In his presidential address to the APA, Alvin Plantinga argues that the only sensible way to be an anti-realist is to be a theist. 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. As it is a contingent matter whether ideal epistemic circumstances obtain, Plantinga concludes that an anti-realist should be a theist. In this paper, we show that counterfactual analyses of truth as epistemic are instances of a more general problem of philosophical analysis. More specifically, without a radical revision of the logic, counterfactual analyses of truth as epistemic cannot avoid perpetrating some version of the conditional fallacy. Even so, we argue, anti-realists are not committed to the necessary existence of ideal epistemic circumstances and therefore need not be theists. (shrink)

Aesthetic reasons are reasons to do and think various things. For example, it makes sense to wonder if a tree stump on the lawn was left there for environmental rather than aesthetic reasons, or for no reason at all. Aesthetic considerations of this kind are often contrasted with non-aesthetic reasons—such as moral or epistemic reasons. For example, they seem connected to pleasure-in-experience in a distinctive way that differs from paradigmatic moral reasons. Relatedly, the authority of aesthetic reasons has often (...) been thought to involve less of an “external demand” upon us than in the other cases. In this chapter, I suggest that such distinctiveness and modesty coheres well with an anti-realist treatment that views them as non-objective in nature. I then go on to consider an alternative, more robustly realist conception of aesthetic reasons. (shrink)

In 1990 Edward Craig published a book called Knowledge and the State of Nature in which he introduced and defended a genealogical approach to epistemology. In recent years Craig’s book has attracted a lot of attention, and his distinctive approach has been put to a wide range of uses including anti-realist metaepistemology, contextualism, relativism, anti-luck virtue epistemology, epistemic injustice, value of knowledge, pragmatism and virtue epistemology. While the number of objections to Craig’s approach has accumulated, there has (...) been no sustained attempt to develop answers to these objections. In this paper we provide answers to seven important objections in the literature. (shrink)

A fragmented and unfirnished exploration into the realist and anti-realist debate in mathematics. And the subsequent exploration of how novelty and creation works on a fundemental epistemic scale. The paper puts forth two major frameworks that attempt to bridge realism and anti-realism and provides a novel solution to the epistemic problem of true novelty and idea generation.

According to Bas van Fraassen, scientific realists and anti-realists disagree about whether accepting a scientific theory involves believing that the theory is true. On van Fraassen’s own anti-realist empiricist position, accepting a theory involves believing only that the theory is correct in its claims about observable aspects of the world. However, a number of philosophers have argued that acceptance and belief cannot be distinguished and thus that the debate is either confused or trivially settled in favor of the (...) realist. In addition, another set of philosophers have argued that van Fraassen’s empiricist position appeals to an unmotivated distinction between observable and unobservable aspects of the world. This paper aims to reconstruct a van Fraassen-style empiricism about scientific acceptance that avoids these two objections – reconstructed empiricism. (shrink)

The nature of vagueness is investigated via a preliminary definition and a discussion of the classical sorites paradox ; this is carried further by asking for the origins of vagueness and a critique of several attempts to remove it from language. It is shown that such attempts are ill motivated and doomed for failure since vagueness is not just a matter of ignorance but firmly grounded in epistemic and metaphysical facts. Finally, the philosophical interest of real vagueness is illustrated (...) by the concept of “natural kind”, which is essential to realism/anti-realism debates. (shrink)

Philosophical debates on how to account for the progress of science have traditionally divided along the realism-anti-realism axis. Relatively recent developments in epistemology, however, have opened up a new knowledge-understanding axis to the debate. This chapter presents a novel understanding-based account of scientific progress that takes its motivation from problem-solving practices in science. Problem-solving is characterized as a means of measuring degree of understanding, which is argued to be the principal epistemic (or cognitive) aim of science, (...) over and against knowledge. This account is then defended against knowledge reductionism by showing how each plays an important and distinctive role in science. (shrink)

Recent work in the metaphysics of gender mostly focuses on trying to solve the exclusion problem - roughly, the problem of giving a metaphysical account of gender that doesn’t exclude anyone from their appropriate gender category. It is acknowledged that no completely satisfactory answer to the exclusion problem has yet been given in the literature; typically such theories fail to account for the diverse experiences and characteristics of trans people. One response is to adopt an anti-realism about gender (...) properties, such as Heather Logue’s gender fictionalism. I rebut the move to an anti-realism, showing that it relies on assuming a representationalism about gender vocabulary that we need not hold. I put forward a non-representationalist theory of gender properties that analyses gender vocabulary in terms of its inferential profile, rather than its representational features. This theory constitutes a deflationary realism about gender properties; it solves the inclusion problem, and guarantees the first-person epistemic authority of an individual regarding their own gender identity.

Suppose one believes that the historical record of discarded scientific theories provides good evidence against scientific realism. Should one adopt Kyle Stanford’s specific version of this view, based on the Problem of Unconceived Alternatives? I present reasons for answering this question in the negative. In particular, Stanford’s challenge cannot use many of the prima facie strongest pieces of historical evidence against realism, namely: superseded theories whose successors were explicitly conceived, and superseded theories that were not the result of (...) elimination-of-alternatives inferences. Attempts to accommodate and within Stanford’s framework are incompatible with other commitments Stanford holds, such as anti-realism being piecemeal instead of global. As separate lines of criticism, I argue that there are problems with Stanford’s claim that the PUA is the most important challenge to realism, and with his view of instrumentalist theory endorsement.

Plausibly, mathematical claims are true, but the fundamental furniture of the world does not include mathematical objects. This can be made sense of by providing mathematical claims with paraphrases, which make clear how the truth of such claims does not require the fundamental existence of mathematical objects. This paper explores the consequences of this type of position for explanatory structure. There is an apparently straightforward relationship between this sort of structure, and the logical sort: i.e. logically complex claims are explained (...) by logically simpler ones. For example, disjunctions are explained by their (true) disjuncts, while generalizations are explained by their (true) instances. This would seem as plausible in the case of mathematics as elsewhere. Also, it would seem to be something that the anti-realist approaches at issue would want to preserve. It will be argued, however, that these approaches cannot do this: they lead not merely to violations of the familiar principles relating logical and explanatory structure, but even to reversals of these. That is, there are cases where generalizations explain their instances, or disjunctions their disjuncts. (shrink)

This paper applies Edward Craig’s and Bernard Williams’ ‘genealogical’ method to the debate between relativism and its opponents in epistemology and in the philosophy of language. We explain how the central function of knowledge attributions -- to ‘flag good informants’ -- explains the intuitions behind five different positions (two forms of relativism, absolutism, contextualism, and invariantism). We also investigate the question whether genealogy is neutral in the controversy over relativism. We conclude that it is not: genealogy is most naturally taken (...) to favour an anti-realism about epistemic norms. And anti-realism threatens absolutism. (shrink)

In this chapter I shall address the question as to whether there exists a universal and atemporal justification for the claims made by a community that adopts a particular style of reasoning. I shall present a case study in which a claim made in the laboratory style of reasoning has no universal and atemporal justification. As I shall explain, Hacking justifies his belief that unobservable entities exist on the ground that they can be regularly manipulated by experimenters in order to (...) find out and produce various phenomena (experimental realism); he also maintains that no belief that our theories are true is required in order to be realist about unobservable entities. I shall argue that his justification is relative to the laboratory style of reasoning. Ultimately, from this case study I shall draw the important conclusion that the styles of reasoning project implies epistemic relativism. In the first part of this chapter, I shall analyse Hacking’s experimental realism in the light of the styles of reasoning project. I shall start by making these points: Hacking’s theory anti-realism denies the possibility of ranking styles of reasoning in terms of their capacity to explain phenomena; furthermore, Hacking is not successful in showing that his entity realism is justified for a community that does not adopt the laboratory style of reasoning. It will follow that the styles of reasoning project is in conflict with the claim that we know about unobservable entities. (shrink)

This paper begins by applying a version of Timothy Williamson’s anti-luminosity argument to normative properties. This argument suggests that there must be at least some unknowable normative facts in normative Sorites sequences, or otherwise we get a contradiction given certain plausible assumptions concerning safety requirements on knowledge and our doxastic dispositions. This paper then focuses on the question of how the defenders of different forms of metaethical anti-realism (namely, error theorists, subjectivists, relativists, contextualists, expressivists, response dependence theorists, (...) and constructivists) could respond to the explanatory challenge created by the previous argument. It argues that, with two exceptions, the metaethical anti-realists need not challenge the argument itself, but rather they can find ways to explain how the unknowable normative facts can obtain. These explanations are based on the idea that our own attitudes on which the normative facts are grounded need not be transparent to us either. Reaching this conclusion also illuminates how metaethical anti-realists can make sense of instances of normative vagueness more generally. (shrink)

The main purpose of this paper is to refute the metaphysicians ‘methodological continuation’ argument supporting epistemic realism in metaphysics. This argument aims to show that scientific realists have to accept that metaphysics is as rationally justified as science given that they both employ inference to the best explanation, i.e. that metaphysics and science are methodologically continuous. I argue that the reasons given by scientific realists as to why inference to the best explanation is reliable in science do not (...) constitute a reason to believe that it is reliable in metaphysics. The justification of IBE in science and the justification of IBE in metaphysics are two distinct issues with only superficial similarities, and one cannot rely on one for the other. This becomes especially clear when one analyses the debate about the legitimacy of IBE that has taken place between realists and empiricists. The metaphysician seeking to piggyback on the realist defense of IBE in science by the methodological continuation argument presupposes that the defense is straightforwardly applicable to metaphysics. I will argue that it is, in fact, not. The favoured defenses of IBE in scientific realism make extensive use of empirical considerations, predictive power and inductive evidence, all of which are paradigmatically absent in the metaphysical context. Furthermore, I argue that the metaphysician, even if the realist would concede to the methodological continuation argument, fails to offer any agreed upon conclusions resulting from its application in metaphysics. As a result, the scientific realist is not committed to believing that there is metaphysical knowledge. (shrink)

Since the publication of the Remarks on the Foundations of Mathematics, Wittgenstein’s interpreters have endeavored to reconcile his general constructivist/anti-realist attitude towards mathematics with his confessed anti-revisionary philosophy. In this article, the author revisits the issue and presents a solution. The basic idea consists in exploring the fact that the so-called “non-constructive results” could be interpreted so that they do not appear non-constructive at all. The author substantiates this solution by showing how the translation of mathematical results, given (...) by the possibility of translation between logics, can be seen as a tool for partially implementing the solution Wittgenstein had in mind.

The critical focus of this paper is on a claim made explicitly by Gilbert Harman and accepted implicitly by numerous others, the claim that naturalism supports concurrent defense of scientific objectivism and moral relativism. I challenge the assumptions of Harman's ‘argument from naturalism' used to support this combination of positions, utilizing. Hilary Putnam’s ‘companions in guilt’ argument in order to counter it. The paper concludes that while domain-specific anti-realism is often warranted, Harman’s own views about the objectivity of (...) facts and the subjectivity of values are better seen as stemming from scientistic ideals of knowledge than from dictates of naturalism. Scientists qua scientists make value judgments, and setting aside scientistic assumptions and unrealizable conceptions of scientific objectivity should lead us to more symmetrical metaphilosophical conception of epistemic and ethical normativity than that which underlies Harman's account.

How to understand Brentano’s account of truth is a question of some controversy. A number of different views have been put forward as positions that Brentano held at some stage in his career. The received view has it that the early Brentano subscribed to a form of correspondence theory which he later rejected in favor of a definition of truth in terms of correct judging, where the correctness of a judgment is defined in terms of the notion of self-evidence (see (...) Kraus 1966, Szrednicki 1965, Stegmüller 1969, Kamitz 1983, Chrudzimski 2001). This fundamental shift in Brentano’s view is regarded as a change from an ontological to a “gnoseological”, i.e. epistemic, theory of truth (see Kastil 1934). Brentano’s mature view is sometimes said to resemble a neo-Kantian conception of truth or related views (see Kraus 1966, van der Schaar 1999, 2003), it has been compared with a coherence theory of truth (see Krantz 1990/91), and it is regarded as embracing a form of alethic anti-realism that places a substantial epistemic constraint on the concept of truth (see Künne 2003). More recently, Charles Parsons suggested that the early Brentano may also be regarded as a precursor of a deflationist theory of truth (see Parsons 2004). Following up on this proposal, the received view has been challenged by a new interpretation that ascribes to Brentano a deflationist position that he held throughout his career in combination with the view that truth pertains primarily to self-evident judgment (see Brandl forthcoming). Section 1 first summarizes the received view and then indicates two problems raised by this interpretation. Section 2 explains in which sense Brentano may have been a deflationist and how this interpretation avoids the problems of the received view. (shrink)

The aim of this study is to justify the belief that there are biological normative mechanisms that fulfill non-trivial causal roles in the explanations (as formulated by researchers) of actions and behaviors present in specific systems. One example of such mechanisms is the predictive mechanisms described and explained by predictive processing (hereinafter PP), which (1) guide actions and (2) shape causal transitions between states that have specific content and fulfillment conditions (e.g. mental states). Therefore, I am guided by a specific (...) theoretical goal associated with the need to indicate those conditions that should be met by the non-trivial theory of normative mechanisms and the specific models proposed by PP supporters. In this work, I use classical philosophical methods, such as conceptual analysis and critical reflection. I also analyze selected studies in the field of cognitive science, cognitive psychology, neurology, information theory and biology in terms of the methodology, argumentation and language used, in accordance with their theoretical importance for the issues discussed in this study. In this sense, the research presented here is interdisciplinary. My research framework is informed by the mechanistic model of explanation, which defines the necessary and sufficient conditions for explaining a given phenomenon. The research methods I chose are therefore related to the problems that I intend to solve. In the introductory chapter, “The concept of predictive processing”, I discuss the nature of PP as well as its main assumptions and theses. I also highlight the key concepts and distinctions for this research framework. Many authors argue that PP is a contemporary version of Kantianism and is exposed to objections similar to those made against the approach of Immanuel Kant. I discuss this thesis and show that it is only in a very general sense that the PP framework is neo-Kantian. Here we are not dealing with transcendental deduction nor with the application of transcendental arguments. I argue that PP is based on reverse engineering and abduction inferences. In the second part of this chapter, I respond to the objection formulated by Dan Zahavi, who directly accuses this research framework of anti-realistic consequences. I demonstrate that the position of internalism, present in the so-called conservative PP, does not imply anti-realism, and that, due to the explanatory role played in it by structural representations directed at real patterns, it is justified to claim that PP is realistic. In this way, I show that PP is a non-trivial research framework, having its subject, specific methods and its own epistemic status. Finally, I discuss positions classified as the socalled radical PP. In the chapter “Predictive processing as a Bayesian explanatory model” I justify the thesis according to which PP offers Bayesian modeling. Many researchers claim that the brain is an implemented statistical probabilistic network that is an approximation of the Bayesian 7 rule. In practice, this means that all cognitive processes are to apply Bayes' rule and can be described in terms of probability distributions. Such a solution arouses objections among many researchers and is the subject of wide criticism. The purpose of this chapter is to justify the thesis that Bayesian PP is a non-trivial research framework. For this purpose, I argue that it explains certain phenomena not only at the computational level described by David Marr, but also at the level of algorithms and implementation. Later in this chapter I demonstrate that PP is normative modeling. Proponents of the use of Bayesian models in psychology or decision theory argue that they are normative because they allow the formulation of formal rules of action that show what needs to be done to make a given action optimal. Critics of this approach emphasize that such thinking about the normativity of Bayesian modeling is unjustified and that science should shift from prescriptive to descriptive positions. In a polemic with Shira Elqayam and Jonathan Evans (2011), I show that the division they propose into prescriptivism and Bayesian descriptivism is apparent, because, as I argue, there are two forms of prescriptivism, i.e. the weak and the strong. I argue that the weak version is epistemic and can lead to anti-realism, while the strong version is ontic and allows one to justify realism in relation to Bayesian models. I argue that a weak version of prescriptivism is valid for PP. It allows us to adopt anti-realism in relation to PP. In practice, this means that you can explain phenomena using Bayes' rule. This does not, however, imply that they are Bayesian in nature. However, the full justification of realism in relation to the Bayesian PP presupposes the adoption of strong prescriptivism. This position assumes that phenomena are explained by Bayesian rule because they are Bayesian as such. If they are Bayesian in nature, then they should be explained using Bayesian modeling. This thesis will be substantiated in the chapters “Normative functions and mechanisms in the context of predictive processing” and “Normative mechanisms and actions in predictive processing”. In the chapter “The Free Energy Principle in predictive processing”, I discuss the Free Energy Principle (hereinafter FEP) formulated by Karl Friston and some of its implications. According to this principle, all biological systems (defined in terms of Markov blankets) minimize the free energy of their internal states in order to maintain homeostasis. Some researchers believe that PP is a special case of applying this principle to cognition, and that predictive mechanisms are homeostatic mechanisms that minimize free energy. The discussion of FEP is important due to the fact that some authors consider it to be important for explanatory purposes and normative. If this is the case, then FEP turns out to be crucial in explaining normative predictive mechanisms and, in general, any normative biological mechanisms. To define the explanatory possibilities of this principle, I refer to the discussion of its supporters on the issue they define as the problem of continuity and discontinuity between life and mind. A critical analysis of this discussion and the additional arguments I have formulated have allowed me to revise the explanatory ambitions of FEP. I also reject the belief that this principle is necessary to explain the nature of predictive mechanisms. I argue that the principle formulated and defended by Friston is an important research heuristic for PP analysis. 8 In the chapter “Normative functions and mechanisms in predictive processing”, I start my analyzes by formulating an answer to the question about the normative nature of homeostatic mechanisms. I demonstrate that predictive mechanisms are not homeostatic. I defend the view that a full explanation of normative mechanisms presupposes an explanation of normative functions. I discuss the most important proposals for understanding the normativity of a function, both from a systemic and teleosemantic perspective. I conclude that the non-trivial concept of a function must meet two requirements which I define as explanatory and normative. I show that none of the theories I have invoked satisfactorily meets both of these requirements. Instead, I propose a model of normativity based on Bickhard's account, but supplemented by a mechanistic perspective. I argue that a function is normative when: (1) it allows one to explain the dysfunction of a given mechanism; (2) it contributes to the maintenance of the organism's stability by shaping and limiting possible relations, processes and behaviors of a given system; and when (3) (according to the representational and predictive functions) it enables explaining the attribution of logical values of certain representations / predictions. In such an approach, a mechanism is normative when it performs certain normative functions and when it is constitutive for a specific action or behavior, despite the fact that for some reason it cannot realize it either currently or in the long-term. Such an understanding of the normativity of mechanisms presupposes the acceptance of the epistemic hypothesis. I argue that this hypothesis is not cognitively satisfactory, and therefore the ontic hypothesis should be justified, which is directly related to adopting the position of ontic prescriptivism. For this reason, referring to the mechanistic theory of scientific explanations, I formulate an ontical interpretation of the concept of a normative mechanism. According to this approach, a mechanism or a function is normative when they perform such and such causal roles in explaining certain actions and behaviors. With regard to the normative properties of predictive mechanisms and functions, this means that they are the causes of specific actions an organism carries out in the environment. In this way, I justify the necessity of accepting the ontic hypothesis and rejecting the epistemic hypothesis. The fifth chapter, “Normative mechanisms and actions in predictive processing”, is devoted to the dark room problem and the related exploration-exploitation trade-off. A dark room is the state that an agent could be in if it minimized the sum of all potential prediction errors. I demonstrate that, in accordance with the basic assumption of PP about the need for continuous and long-term minimization of prediction errors, such a state should be desirable for the agent. Is it really so? Many authors believe it is not. I argue that the test of the value of PP is the possibility of a non-trivial solution of this problem, which can be reduced to the choice between active and uncertainty-increasing exploration and safe and easily predictable exploitation. I show that the solution proposed by PP supporters present in the literature does not enable a fully satisfactory explanation of this dilemma. Then I defend the position according to which the full explanation of the normative mechanisms, and, subsequently, the solution to the dilemma of exploration and exploitation, involves reference to the existence of constraints present in the environment. The constraints 9 include elements of the environment that make a given mechanism not only causal but also normative. They are therefore key to explaining the predictive mechanisms. They do not only play the role of the context in which the mechanism is implemented, but, above all, are its constitutive component. I argue that the full explanation of the role of constraints in normative predictive mechanisms presupposes the integration of individual models of specific cognitive phenomena, because only the mechanistic integration of PP with other models allows for a non-trivial explanation of the nature of normative predictive mechanisms that would have a strong explanatory value. The explanatory monism present in many approaches to PP makes it impossible to solve the problem of the dark room. Later in this chapter, I argue that the Bayesian PP is normative not because it enables the formulation of such and such rules of action, but because the predictive mechanisms themselves are normative. They are normative because they condition the choice of such and such actions by agents. In this way, I justify the hypothesis that normative mechanisms make it possible to explain the phenomenon of agent motivation, which is crucial for solving the dark room problem. In the last part of the chapter, I formulate the hypothesis of distributed normativity, which assumes that the normative nature of certain mechanisms, functions or objects is determined by the relations into which these mechanisms, functions or objects enter. This means that what is normative (in the primary sense) is the relational structure that constitutes the normativity of specific items included in it. I suggest that this hypothesis opens up many areas of research and makes it possible to rethink many problems. In the “Conclusion”, I summarize the results of my research and indicate further research perspectives. (shrink)

Call ‘radical moral theorizing’ the project of developing a moral theory that not only tries to conform to our existing moral judgments, but also manifests various theoretical virtues: consistency, simplicity, explanatory depth, and so on. Many moral philosophers assume that radical moral theorizing does not require any particular metaethical commitments. In this paper, I argue against this assumption. The most natural justification for radical moral theorizing presupposes moral realism, broadly construed; in contrast, there may be no justification for radical (...) moral theorizing if moral anti-realism is true.

Sellars was an inferentialist about meaning. He thus effectively accorded modality a categorial function, maintaining that any meaningful assertion involves implicit commitment to rules of material inference, which modal propositions explicitly endorse. But Sellars was also a modal anti-realist, construing modality as “entirely immanent to thought” (LRB §40), not present in the world an sich. These two commitments, Klemick argues, render it impossible in principle for us to describe the world an sich adequately, undermining Sellars’ scientific realism, on (...) which, at the “ideal outcome of scientific inquiry,” “the gulf between appearances and things-in-themselves [... can] be bridged” (SM II §51). Sellars’ attempt to ground his modal anti-realism in an ideal “pure description of the world” (CDCM §79) cannot succeed, given modality’s categorial function. Further, his subsequent deployment of picturing as a naturalistic criterion of ontological commitment founders on an analogue of the Kantian problem of noumenal affection: the descriptions of picturing relations that render this proposal intelligible are emptied of content by the denial that the in-itself is modally characterized. Sellars’ worthy aim of preserving the world’s independence of our conceptual activity, Klemick concludes, doesn’t require denying that it exhibits modal relations isomorphic to the semantic relations within our conceptual scheme.

In order to re-contextualize the otherwise ontologically privileged meaning of metaphysical debates into a more insubstantial form, metaphysical deflationism runs the risk of having to adopt potentially unwanted anti-realist tendencies. This tension between deflationism and anti-realism can be expressed as follows: in order to claim truthfully that something exists, how can deflationism avoid the anti-realist feature of construing such claims singularly in an analytical fashion? One may choose to adopt a Yablovian fallibilism about existential claims, but (...) other approaches can be appealed to as well. Amie Thomasson's Easy Ontology is one such approach, whereby the interaction of empirical as well as analytic features within the construction of its ontological theory affords a role for analytical rules without forsaking a link with empirical reality. The development of these analytical and empirical features has resulted in significant critiques regarding, one, potential reference failure of easy-ontological claims, and two, a circularity in how easy ontology explains the relation between its analytical rules and existential claims. This essay offers a response by showcasing how an easy ontological deflationism can reject these criticisms without succumbing to, one, the anti-realism of pure analyticism, and two, a further critique of wholesale referential indeterminacy in its referring terms.

Realism about consciousness conjoins a claim that consciousness exists with a claim that the existence is independent in some interesting sense. Consciousness realism so conceived may thus be opposed by a variety of anti-realisms, distinguished from each other by denying the first, the second, or both of the realist’s defining claims. I argue that Dennett’s view of consciousness is best read as an anti-realism that affirms the existence of consciousness while denying an important independence claim.

Here the relationship between understanding and knowledge of meaning is discussed from two different perspectives: that of Dummettian semantic anti-realism and that of the semantic externalism of Putnam and others. The question addressed is whether or not the truth of semantic externalism would undermine a central premise in one of Dummetts key arguments for anti-realism, insofar as Dummetts premise involves an assumption about the transparency of meaning and semantic externalism is often taken to undermine such transparency. (...) Several notions of transparency and conveyability of meaning are distinguished and it is argued that, though the Dummettian argument for anti-realism presupposes only a weak connection between knowledge of meaning and understanding, even this much is not trivially true in light of semantic externalism, and that semantic externalism, if true, would thus represent a reason for rejecting the crucial assumption on which the Dummettian argument depends.

A linguistic convention is a principle or norm that has been adopted by a person or linguistic community about how to use, and therefore what the meaning is of, a specific term. Examples of such norms or principles are those expressed by propositions that express the laws of logic or those that express implicit definitions. Arguments about the epistemic status of linguistic conventions, very broadly, fall into two camps: the one holds that the basis of linguistic conventions is objective (...) and that, therefore, such conventions are genuinely truth-bearing. Knowledge of such conventions is therefore knowledge of the objective truth of such conventions. This camp might be labelled ‘realist’. The other holds that there is no known basis to linguistic conventions and that conventions are, to the best of our knowledge, not objective, but invented. Their truth is stipulated by the relevant speaker or linguistic community. Such truth is, consequently, trivial and knowledge of such conventions simply knowledge of the stipulation. This camp might be labelled ‘anti-realist’. These are three standard accounts of the epistemic status of linguistic conventions, which all play into the first camp: (1) knowledge by intuition, (2) inferential a priori knowledge and (3) a posteriori knowledge. I give reasons why these accounts should be rejected. I then argue that linguistic conventions, if conceived of as trivial truths, are knowable non-inferentially a priori. Such an epistemic account provides support for the second camp. In this regard, I marshal support from some recent work by Wright and Hale. (shrink)

The perennial nature of some of philosophy’s deepest problems is a puzzle. Here, one problem, the realism–anti-realism debate, and one type of explanation for its longevity, are examined. It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In (...) the following sections, the dialetheic conclusion is directly argued for by showing how realism and anti-realism satisfy Priest’s “inclosure schema”. In the last section and the conclusion, the conscious mind’s role in creating realism and anti-realism is discussed. This role further supports the conclusion that realism and anti-realism form a dialetheic pair. (shrink)
