This dissertation attempts to defend the justifiability of our belief that there is an external world. I begin by investigating what such a claim means and how it fits in with a common sense "realism." The idea put forth is that the latter asserts not only that there is an external world but also what there is in it. So, the bare assertion about the existence of the external world is only a part of common sense. However, I claim (...) that even such a 'mitigated realism' can be interesting and indicate how Putnam's internal realism amounts to just this. ;I then discuss "epistemological arguments" against realism so defined. These are arguments that begin with the epistemological theses and conclude the denial of realism--a strategy found even in the classic idealist Bishop Berkeley. The steps from such epistemic premises to a metaphysical conclusion are spelled out and the general conception of the epistemological project that underlies and warrants such an inference is explored. What emerges is that to be relevant for metaphysics, epistemic debates must be both non-question-begging and epistemic justifiability must be defined in terms of truth-conduciveness. A model of how epistemology can incorporate these features is suggested. ;The last part of the discussion aims at rejecting the epistemic premises of such anti-realist arguments. This amounts to claiming that an external world is both believable and justified. The arguments of Donald Davidson and Laurence Bonjour claiming to establish this are discussed and criticised. A final vindication, however, is given by reformulating Hilary Putnam's brains-in-a-vat argument. What emerges from the discussion is that just as metaphysics cannot be done in isolation from epistemology, epistemology too cannot be done independently of a theory of intentionality and belief.

Putnam's ``model-theoretic'' argument against metaphysical realism presupposes that an ideal scientific theory is expressible in a first order language. The central aim of this paper is to show that Putnam's ``first orderization'' of science, although unchallenged by numerous critics, makes his argument unsound even for adequate theories, never mind an ideal one. To this end, I will argue that quantitative theories, which dominate the natural sciences, can be adequately interpreted and evaluated only with the help of so-called theories (...) of measurement whose epistemological and methodological purpose is to justify systematic assignments of quantitative values to objects in the world. And, in order to fulfill this purpose, theories of measurement must have an essentially higher order logical structure. As a result, Putnam's argument fails because much of science turns out to rest on essentially higher order theoretical assumptions about the world. (shrink)

Recent work in defence of direct realism has concentrated on the representationalist and disjunctivist responses to the arguments from illusion and hallucination, whilst relatively little attention has been given to the argument from causation which has been dismissed lightly as irrelevant or confused. However such charges arise from an ambiguity in the thesis which is being defended and the failure to distinguish between metaphysical and epistemological issues and between factual and conceptual claims. The argument from causation, as (...) an argument against the conjunction of metaphysical direct realism and an explanation of the perceptual process in terms of a naturalistically understood causal chain of events, has not been answered in the philosophical literature. Moreover when the process of perception is fleshed out in terms of contemporary cognitive science, the difficulties are compounded. Neither representation-friendly mainstream cognitive science, nor representation-averse radical embodied cognitive science, is compatible with a theory of perception which is at the same time both direct and robustly realist.

This paper explores the options available to the anti-realist to defend a Quinean empirical under-determination thesis using examples of dualities. I first explicate a version of the empirical under-determination thesis that can be brought to bear on theories of contemporary physics. Then I identify a class of examples of dualities that lead to empirical under-determination. But I argue that the resulting under-determination is benign, and is not a threat to a cautious scientific realism. Thus dualities are not new ammunition (...) for the anti-realist. The paper also shows how the number of possible interpretative options about dualities that have been considered in the literature can be reduced, and suggests a general approach to scientific realism that one may take dualities to favour.

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role in explaining our moral (...) beliefs, (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

If what is morally right or wrong were ultimately a function of our opinions, then even such reprehensible actions as genocide and slavery would be morally right, had we approved of them. Many moral philosophers find this conclusion objectionably permissive, and to avoid it they posit a moral reality that exists independently of what anyone thinks. The notion of an independent moral reality has been subjected to meticulous metaphysical, epistemological and semantic criticism, but it is hardly ever examined from (...) a moral point of view. In this essay I offer such a critique. I argue that the appeal to an independent moral reality as a ground for moral obligations constitutes a substantive moral mistake. However, I do not conclude from this that we must therefore embrace the opposite view that moral truths are ultimately dependent on our attitudes. Rather, I suggest that we reject both of these views and answer the classic meta-ethical question “Is what we morally ought to do ultimately a function of our actual attitudes, or determined independently of them?” with Neither.

This paper formulates a general epistemological argument against what I call non-causal realism, generalizing domain specific arguments by Benacerraf, Field, and others. First I lay out the background to the argument, making a number of distinctions that are sometimes missed in discussions of epistemological arguments against realism. Then I define the target of the argument—non-causal realism—and argue that any non-causal realist theory, no matter the subject matter, cannot be given a reasonable (...) epistemology and so should be rejected. Finally I discuss and respond to several possible responses to the argument. In addition to clearing up and avoiding numerous misunderstandings of arguments of this kind that are quite common in the literature, this paper aims to present and endorse a rigorous and fully general epistemological argument against 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. (shrink)

The dissertation involves an examination of recent work in Social Epistemology. In particular, I am concerned with the question of how one's social position could affect judgments regarding evidence and confirmation. To answer this question I undertake an investigation of feminist epistemology and philosophy of science. Feminist epistemologists have raised criticisms of the traditional analysis of knowledge by arguing against the primacy of the individual and for a more thorough-going analysis of the community in accounts of knowledge. This shift, (...) in my view, is an important contribution toward a more complete theory of knowledge. Yet feminist epistemology is a controversial contributor to the area of social epistemology generally construed. Thus, in the first chapter I offer a defense of the contributions of feminist epistemology to analytic philosophy, against its various critics. ;In Chapters Two and Three I examine feminists' reliance on Naturalistic models of theory-choice such as Quinean Holism or the later Wittgenstein's Social Constructivism. I argue that the reliance on these models is a tactical mistake for feminists since these models are based on problematic accounts of meaning and truth. Alternatively, I advocate the adoption of a realist meaning theory along the lines proposed by Katz, as well as a rationalized epistemology in the service of explaining deductive and inductive inference. My argument involves showing how realism and rationalism entail the kind of strong program of justification and rational censure which is required if feminists want to successfully condemn existing biased practices. ;Consequently, I propose a reformulation of the distinction between a context of discovery and context of justification. My reformulation differs from the past positivist distinction in that "discovery" rather than being wholly random and subjective, is instead reflective of patterns of social experience. "Justification" is conceived of as more sensitive to the epistemic privilege of varying social standpoints. However, a separation is still maintained between how one comes to arrive at a belief and the methods for justifying that belief. My conclusion is that a partnership between rationalized epistemology and feminist theory can provide rich possibilities for both disciplines. (shrink)

Moorean arguments are a popular and powerful way to engage highly revisionary philosophical views, such as nihilism about motion, time, truth, consciousness, causation, and various kinds of skepticism (e.g., external world, other minds, inductive, global). They take, as a premise, a highly plausible first-order claim (e.g., cars move, I ate breakfast before lunch, it’s true that some fish have gills) and conclude from it the falsity of the highly revisionary philosophical thesis. Moorean arguments can be used against (...) nihilists in ethics (error theorists), too. Recently, error theorists have recognized Moorean arguments as a powerful challenge and have tried to meet it. They’ve argued that moral Moorean premises seem highly credible to us, but aren’t, by offering various debunking explanations. These explanations all appeal to higher-order evidence—evidence of error in our reasoning. I argue that drawing attention to higher-order evidence is a welcome contribution from error theorists, but that the higher-order evidence actually counts further against error theoretic arguments—including their debunking explanations—and further in favor of Moorean arguments and the commonsense views they support. Along the way I answer a few prominent objections to Moorean arguments: that they are objectionably question-begging, rely on categorizing some facts as “Moorean Facts”, and that reports of one’s credence in a proposition bears no interesting relation to that proposition’s credibility.

The main problem of this study is David Hume’s (1711-76) view on Metaphysical Realism (there are mind-independent, external, and continuous entities). This specific problem is part of two more general questions in Hume scholarship: his attitude to scepticism and the relation between naturalism and skepticism in his thinking. A novel interpretation of these problems is defended in this work. The chief thesis is that Hume is both a sceptic and a Metaphysical Realist. His philosophical attitude is to suspend his (...) judgment on Metaphysical Realism, whereas as a common man he firmly believes in the existence of mind-independent, external, and continuous entities. Therefore Hume does not have any one position; accordingly, a form of “no one Hume” interpretation (Richard Popkin, Robert J. Fogelin, Donald L.M. Baxter) is argued for in the book. The key point in this distinction is the temporal difference between Hume’s philosophical and everyday views. It is introduced in order to avoid attributing a conscious contradiction to him (a problem which has not attracted enough attention in the literature). The method of the work is modelled on Peter Millican’s work on Hume and induction. The approach to the main problem is to study the two “profound” arguments against the senses that Hume presents in the Section 12 of An Enquiry concerning Human Understanding (1748). These arguments are first reconstructed in detail resulting in Millican-type diagrams of them and then Hume’s endorsement of them is established on the basis of the diagrams. The first profound argument concludes that Metaphysical Realism and thus any Realistic theory of perception is unjustified as well as the existence of God and the soul. The second argument goes further having first conceptual conclusion: the very notions of Real entitity, material substance, and bodies are completely out of the reach of the faculty of understanding. Therefore they ought to be rejected according to Hume. This is a consequence of the consistent use of the Humean faculty of reason: idea-analysis and inductive inference. The second profound argument thus concludes that believing in Metaphysical Realism is inconsistent with the rational attitude that is to refrain from this belief. Hence, if we attributed both of them to Hume, we would end up with a great philosopher who embraces a manifest contradiction. The study is finished by arguing that this sceptical and Metaphysically Realistic interpretation concurs well with (1) Hume’s professed Academical philosophy and (2) project of the science of human nature. (1) According to Hume, Academical philosophy is in the first place diffidence, modesty, and uncertainty including suspension on certain issues. Secondly, it is restriction of the range of topics for which experience can provide a standard of truth. This kind of empiricist epistemological realism is coherent with the sceptical attitude on Metaphysical Realism because the latter does not rule out inter-subjective consensus on what we experience. (2) Suspension of judgment on Metaphysical Realism coheres with the mind-dependency of the objects of Hume’s science of human nature: the understanding, passions, morals, aesthetics, politics, and the human culture in all of its manifestations. Although the study takes the first Enquiry to be Hume’s authorised word on the understanding, his juvenile work A Treatise of Human Nature (1739-40) is argued to support this “no one Hume” interpretation. Hume’s other works are also discussed when needed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Notes and Fragments RAILING AGAINST REALISM: PHILOSOPHY AND TO THE LIGHTHOUSE by S. P. ROSENBAUM The argument of Graheim Parkes's "Imagining Reality in To the Lighthouse" is described by its author as "a railing against the realist position" (p. 35) as he understands it primarily in my article "The Philosophical Reedism ofVirginia Woolf." ' Apart from the question of whemer railing is a useful way of (...) conducting an inquiry into literature and philosophy, Parkes's discussion raises several important issues about these connections. The way diey are raised, however, involves various mistedces and muddles that make a brief reply to his eurticle difficult. To begin with a small reveeding example, Parkes asserts that I miss the irony in Virginia Woolfs use of die letters P, Q, and R to describe Mr. Ramsay's problems of diought (p. 41). Here is what I wrote: "By representing Mr. Ramsay 's thinking as proceeding in die very genered form of conventional logical symbols, Virginia Woolf is wittily extending the standard letters used to symbolize die conditional type of argument, If P men Cf (p. 339, with italics added this time). Parkes's misreading of my text does not inspire confidence when he turns to Virginia Woolfs fiction or G. E. Moore's philosophy. On a more significant issue, Parkes complains that I boggle his mind by saying diat philosophically, Moore influenced Virginia Woolf more man anyone else, whereas Platonic ideas abound in her books (p. 35). Of course they do, but not very much in her epistemology, which was the subject of my eurticle.2 What Peirkes does not mention is that Plato was also a profound influence on Moore's philosophy. One of die reasons Moore's influence on Bloomsbury was so strong is that he reinterpreted Plato for them. In her images and ideas Virginia Woolf was influenced direcdy dirough her reading of Plato etnd also indirectly through the work of Plotinus and Moore. These influences are not easily sepeurated, which is why studies of Platonic emd Neoplatonic influences in her work that ignore Moore's significance are so incomplete. 89 90Philosophy and Literature Peirkes claims mat die evidence of Moore's influence on Virginia Woolf is slight (p. 34), and then he concerns himself with the putative influences of German philosophers for whom mere is no evidence at all. In the fifteen years since I wrote my article, the biographical evidence for Moore's influence has continued to accumulate as Virginia Woolfs letters, memoirs, emd dieiries were published. From her first novel, in which Principia Etnica is quoted emd briefly discussed, down to die recently discovered revised version of her last memoir, in which she reaffirms her deep respect for Moore,3 the indications of Moore's significance for Virginia Woolf ought to convince any disinterested reader. It cannot be dismissed with a sneer about "the voguish fascination of the Bloomsbury Group..." (p. 34), especially from someone proposing to study yet again the depth psychology of her fiction via Nietzsche and Heidegger (P- 44). Nothing I say here, of course, will persuade Parkes of the value of philosophical realism for understanding To the Lighthouse because diat philosophy, as he conceives of it in his article, consists of straw. To tedce just one exeimple, Peirkes appeeurs to believe Moore's epistemology etrgues "diat things and persons are what they are independently of human consciousness" (p. 37). There is no space here to explain philosophical realism again to Parkes, odier than to note that it is not inconsistent with the veirious concerns (to use Peurkes's terminology) about "transpersonal imagination" or "participation in phenomena" that he finds so interesting in the novel. But what about die novel? For readers indifferent to whether Moore or Russell, Nietzsche or Heidegger are to be found in To the Lighthouse, the relevant question is what such philosophical interpretations medce of it. To them I ceui only say, reread the novel and then ask yourselves if an account of it diat says nothing about die value of art and almost nodiing about the value oflove bears much resemblance to your reading experience. Parkes thinks the portrait of Mr. Ramsay is unsympathetic because he is criticized emd mocked... (shrink)

Abstract: Hilary Putnam has reformulated his model-theoretic argument as an argument against indirect realism in the philosophy of perception. This new argument is reviewed and defended. Putnam’s new focus on philosophical theories of perception (instead of metaphysical realism) makes better sense of his previous responses to the objection from the causal theory of reference. It is argued that the model-theoretic argument can also be construed as an argument that holders of a causal theory of reference should adopt (...) direct realism in the philosophy of perception.

I present two generalizations of Putnam's model-theoretic argument against realism. The first replaces Putnam's model theory with some new, and substantially simpler, model theory, while the second replaces Putnam's model theory with some more accessible results from astronomy. By design, both of these new arguments fail. But the similarities between these new arguments and Putnam's original arguments illuminate the latter's overall structure, and the flaws in these new arguments highlight the corresponding flaws in Putnam's (...) arguments.

Sharon Street has argued that we should reject theism because we can accept it only at the cost of having good reason to doubt the reliability of our judgments as to what moral reasons there are. The success of her argument depends on the assumption that no realist account of normative reasons that validates commonsense morality has a tenable secular epistemology. I argue that even given this assumption Street’s argument does not succeed.

Is structure a fundamental and indispensable part of the world? Is the question of ontology a question about structure? Structure is a central notion in contemporary metaphysics [Sider 2011. Writing the Book of the World. Oxford: Clarendon Press]. Realism about structure claims that the question of ontology is about the fundamental and indispensable structure of the world. In this paper, I present a criticism of the metaphysics of realism about structure based on a version of Russell’s famous regress (...) argument against nominalism [Russell 1911. “On the Relation of Universals and Particular.” In Logic & Knowledge. Reprint, London: George Allen & Unwin]. First, I argue that the three general tests for the fundamentality of structure proposed by realism about structure rely on a particular empirical test for structure, namely, the so-called ‘similarity test for structure.’ Second, I argue that the similarity test is not well-founded because it leads to a vicious regress. Third, I argue that the regress affects the whole metaphysics of realism about structure, and that no structural notion can be said to be fundamental in connection with any of the other tests. Lastly, I argue that the question of ontology as a question about structure is not substantive. (shrink)

The epistemological argument against descriptivism about proper names is extremely simple. Fora proper name ‘N’ and definite description ‘F’, the proposition expressed by “If N exists, then N is F is not normally known a priori. But descriptivism about proper names entails otherwise. So descriptivism is false. The argument is widely regarded as sound. This paper aims to establish that the epistemological argument is highly unstable. The problem with the argument is that there seems to be no (...) convincing rationale for the first premise that is independent of a view about the nature of the proposition expressed by the sentence “If N exists, then N is F”.

Even though he is not very explicit about it, in “Wittgenstein on Rules and Private Language” Kripke discusses two different, albeit related, skeptical theses ‒ the first one in the philosophy of mind, the second one in the philosophy of language. Usually, what Kripke says about one thesis can be easily applied to the other one, too; however, things are not always that simple. In this paper, I discuss the case of the so-called “Normativity Argument” against semantic dispositionalism (which (...) I take to be epistemological in nature) and argue that it is much stronger as an argument in the philosophy of mind than when it is construed as an argument in the philosophy of language. (shrink)

Most contemporary political philosophers deny that justice requires giving people what they deserve. According to a familiar anti-desert argument, the influence of genes and environment on people's actions and traits undermines all desert-claims. According to a less familiar – but more plausible – argument, the influence of genes and environment on people's actions and traits undermines some desert-claims (or all desert-claims to an extent). But, it says, we do not know which ones (or to what extent). This article examines this (...) ‘epistemological’ argument against desert. It gives reason to believe that it fails, emphasizing the importance of justice relative to efficiency and attempting to construct a practical way of measuring desert. (shrink)

I argue for the claim that if Lewis’s regularity theory of laws were true, we could not know any positive law statement to be true. Premise 1: According to that theory, for any law statement true of the actual world, there is always a nearby world where the law statement is false (a world that differs with respect to one matter of particular fact). Premise 2: One cannot know a proposition to be true if it is false in a nearby (...) world (the epistemological safety principle). The conclusion that no law statement can be known to be true follows immediately from the two premises. (shrink)

’Death’ and ’Furniture’ are emblems for two very common (predictable, even) objections to relativism. When relativists talk about the social construction of reality, truth, cognition, scientific knowledge, technical capacity, social structure and so on, their realist opponents sooner or later start hitting the furniture, invoking the Holocaust, talking about rocks, guns, killings, human misery, tables and chairs. The force of these objections is to introduce a bottom line, a bedrock of reality that places limits on what may be treated as (...) epistemologically constructed or deconstructible. There are two related kinds of moves: Furniture (tables, rocks, stones, etc. - the reality that cannot be denied) and Death (misery, genocide, poverty, power - the reality that should not be denied). Our aim is to show how these ’but surely not this’ gestures and arguments work, how they trade off each other, and how unconvincing they are, on examination, as refutations of relativism. (shrink)

This paper sets out to assess the internal coherence of Roy Bhaskar's transcendental realist account of science. Whilst fully supporting his transcendental derivation of a stratified ontology of structures and generative mechanisms from the scientific practice of experimentation, I argue that Bhaskar's adoption of the stance of epistemic relativism results in his inability to defend the generalizability of this ontology. My argument against his epistemic stance turns on the fact that it rests on a false dichotomy between epistemic relativism (...) and epistemic absolutism, and, moreover, that it is quite unnecessary for his efforts to avoid the excesses of epistemological foundationalism. The net result of this stance, in my view, is an inability to sustain the normative force of the concepts of truth and scientific explanation precisely at a time when postmodern authors are denying their privileged status.

Hayek's and Mises's argument for the impossibility of socialist planning is once again popular. Their case against socialism is predicated on an account of the nature of knowledge and social interaction. Hayek refined Mises's original argument by developing a philosophical anthropology which depicts individuals as tacitly knowledgeable rule-followers embedded in a 'spontaneous order' of systems of rules. Giddens, whose social theory is informed by his reading of Wittgenstein, has recently added his sociological support to Hayek's 'epistemological argument' (...) class='Hi'>against socialism. With the aid of an interpretation of Wittgenstein which emphasizes his philosophy of praxis , I attempt to 'deconstruct' Giddens's and Hayek's 'picture' of tacit knowledge and rule-following on which their argument against socialism is predicated.

What sorts of aims, or goals, are constitutive of science? How does scientific evidence relate to the knowledge that science produces? And can the No Miracles Argument for scientific realism be defended against concerns about the explanatory capacity of truth? In Knowing Science, Bird engages with questions like these at length. In this paper, I engage with these questions too. I raise some concerns for the view that aiming at knowledge is constitutive of science. I provide three counterexamples (...) to an epistemic principle which Bird uses to argue for the view that evidence is knowledge. And I formulate a version of the No Miracles Argument which, by basing realism on a particular approach to meaning and to the empirical science of linguistics, avoids any mention of truth whatsoever.

Based on original translations of passages from the works of three major thinkers of the classical Indian school of Advaita (Sankara, Vacaspati and Sri Harsa), but addressing issues found in Descartes, Berkeley, Hume, Kant, Wittgenstein and contemporary analytic philosophers, this book argues for a philosophical position it calls 'non-realism'. This is the view that an independent, external world must be assumed if the features of cognition are to be explained, but that it cannot be proved that there is such (...) a world, independently of an appeal to cognition itself. This position is constructed against idealist denials of externality, realist arguments for an independent world and the sceptical denial of the coherence of cognition. (shrink)

Platonism in the philosophy of mathematics is the doctrine that there are mathematical objects such as numbers. John Burgess and Gideon Rosen have argued that that there is no good epistemological argument against platonism. They propose a dilemma, claiming that epistemological arguments against platonism either rely on a dubious epistemology, or resemble a dubious sceptical argument concerning perceptual knowledge. Against Burgess and Rosen, I show that an epistemological anti- platonist argument proposed by Hartry (...) Field avoids both horns of their dilemma. (shrink)

Moral realism is often taken to have common sense and initial appearances on its side. Indeed, by some lights, common sense and initial appearances underlie all the central positive arguments for moral realism. We offer a kind of debunking argument, taking aim at realism’s common sense standing. Our argument differs from familiar debunking moves both in its empirical assumptions and in how it targets the realist position. We argue that if natural selection explains the objective phenomenology (...) of moral deliberation and judgement, then this undermines arguments from that phenomenology. This results in a simpler, and in some ways more direct, challenge to realism. It is also less vulnerable to the main objections that have been leveled against such arguments. If accepted, our conclusion should make a real difference to the dialectic in this area. It means that neither realism nor its denial is the default, to-be-refuted, position. (shrink)

Problem: Is Niklas Luhmann’s theory of social systems based on a constructivist or on a realist epistemology? Luhmann’s own elaborations seem to oscillate between both standpoints. Method: The argumentation provided in this article starts with a detailed reconstruction of Luhmann’s epistemology and of Luhmann’s criticism towards radical constructivism and then examines the consequences for a comparison of systems theory and (radical) constructivism. Results: Although Luhmann’s operative constructivism can be distinguished from radical constructivism, the differences are not considered fundamental. Luhmann’s epistemology (...) is clearly nearer to constructivism than to realism and it shares most of constructivism’s key concepts, such as self-referential logic, a strict relation between observer and observed, and the relativism of reality construction. Implications: Luhmann’s criticism of radical constructivism must be understood in the context of his sociological background. Most of his arguments against radical constructivism can be considered apprehensions of misleading interpretations of radical constructivism rather than of substantial criticism. They may help to clarify a radical constructivist epistemology. Constructivist content: The paper attempts to check whether Luhmann’s theory of social theory is based on (radical) constructivist epistemology. (shrink)

In "Realism and Reason" Hilary Putnam has offered an apparently strong argument that the position of metaphysical realism provides an incoherent model of the relation of a correct scientific theory to the world. However, although Putnam's attack upon the notion of the "intended" interpretation of a scientific theory is sound, it is shown here that realism may be formulated in such a way that the realist need make no appeal to any "intended" interpretation of such a theory. (...) Consequently, it can be shown that realism is immune to Putnam's criticism and that attempts at reformulating this criticism are not likely to meet with success. (shrink)

A long-standing family of worries about moral realism focuses on its implications for moral epistemology. The underlying concern is that if moral truths have the nature that realists believe, it is hard to see how we could know what they are. This objection may be called the “argument from skepticism” against moral realism. Realists have primarily responded to this argument by presenting accounts of how we could acquire knowledge of moral truths that are consistent with realist assumptions (...) about their nature. Less time has been spent, however, on the question of why it would be a problem for moral realism if it leads to skepticism in the first place, and on the related question of which skeptical conclusions it would be problematic for realists to simply accept. This paper considers several answers to these questions, thereby distinguishing a number of versions of the argument from skepticism, and discusses their prospects. (shrink)

Hilary putnam has tried to refute the realist doctrine that the operational verification of a theory never logically precludes its objective falsity by means of an argument involving model-theoretic considerations. in this paper it is first shown that this argument does not work if the theory in question is open to revision. next it is argued that a realist need not and should not admit the notion of the sort of unrevisable, ideal theory required for the purposes of putnam's argument.

Hartry Field's formulation of an epistemological argument against platonism is only valid if knowledge is constrained by a causal clause. Contrary to recent claims (e.g. in Liggins (2006), Liggins (2010)), Field's argument therefore fails the very same criterion usually taken to discredit Benacerraf's earlier version.

Structural realism is a rather popular view in philosophy of science. As with many popular views, sprouting is never far behind. No sprout has had as much grip on the view’s image as ontic structural realism. Indeed its supporters have such a stranglehold that ‘structural realism’ has almost become a byword for their views. In this talk, I want to redress this imbalance by returning to structural realism’s humble epistemic beginnings to examine exactly what made the (...) view so attractive in the first place. To this effect, I will reconstruct several arguments – some of which little known – proposed in the early part of the twentieth century in support of the epistemic version of structural realism. Not wanting to dwell too much on the past, I will then switch to more recent arguments both for and against the position. A careful evaluation of these arguments will hopefully provide useful information as to what form, if any, epistemic structural realism must take in order to be a viable alternative to its direct competitors, namely standard scientific realism and constructive empiricism.

The argument I present here is an example of the manner in which naturalizing epistemology can help address fairly traditional epistemological issues. I develop one argument against coherentist epistemologies of empirical knowledge. In doing so, I draw on BonJour (1985), for that account seems to me to indicate the direction in which any plausible coherentist account would need to be developed, at least insofar as such accounts are to conceive of justification in terms of an agent (minimally) possessing (...) articul able reasons and arguments, as is standard. I end by indicating important elements of coherentist epistemology that can be salvaged in the face of my argument, provided we are willing to drop the traditional commitment to characterizing justification in terms of the structure of articulable argument.

The purpose of the paper is to cast doubt on the alleged intuitive or natural character of the skeptical argument about the external world. In §1, we examine a version of the skeptical argument based on the epistemic closure principle and the indifference principle. In §2, in order to deepen the view defended by Michael Williams, we offer a novel examination of the Cartesian skeptical argumentation to show that it is clear that the alleged naturalness claimed by the skeptic is (...) nowhere to be found in two arguments which can be found in such argumentative strategy; moreover, to reach her conclusion, the skeptic needs to commit to epistemological realism, namely, the claim that each of our beliefs belongs to an epistemological hierarchy based solely on its content. In §3, based on arguments inspired by Wittgenstein, contra epistemological realism, we show how each belief has a justificatory role based on its context. (shrink)

Criticisms à la Laudan can block the “no miracles” argument for the (approximate) truth of whole theories. Realists have thus retrenched, arguing that at least the individual claims deployed in the derivation of novel predictions should be considered (approximately) true. But for Lyons (2002) there are historical counterexamples even to this weaker “deployment” realism: he lists a number of novel predictions supposedly derived from (radically) false claims. But if so, those successes would seem unexplainable, even by Lyons’ “modest surrealism” (...) or other surrogates to realism. In fact, I argue, some of those predictions were an easy guess, or independently probable in the light of available evidence; hence, they are no counterexamples to deployment realism, for the no miracles argument wouldn’t apply to them. In other instances, pace Lyon, the prediction was actually false, and could be reinterpreted as true only by interpreting as true also the claim from which it was derived; or again, a false claim was employed in the derivation of a true prediction, but inessentially, the essential role being played by a weaker true claim. But as soon as the paradoxical air of such historical cases is explained away in any of these manners, they cease to represent counterexamples to deployment realism. If, as I suggest, all of them can be dealt with by these strategies, a theoretical claim can still be assumed to be true if it is crucial in deriving an improbable novel prediction. (shrink)

The aim of this article is to identify the strongest evolutionary debunking argument against moral realism and to assess on which empirical assumptions it relies. In the recent metaethical literature, several authors have de-emphasized the evolutionary component of EDAs against moral realism: presumably, the success or failure of these arguments is largely orthogonal to empirical issues. I argue that this claim is mistaken. First, I point out that Sharon Street’s and Michael Ruse’s EDAs both involve (...) substantive claims about the evolution of our moral judgments. Next, I argue that combining their respective evolutionary claims can help debunkers to make the best empirical case against moral realism. Some realists have argued that the very attempt to explain the contents of our endorsed moral judgments in evolutionary terms is misguided, and have sought to escape EDAs by denying their evolutionary premise. But realists who pursue this reply can still be challenged on empirical grounds: debunkers may argue that the best, scientifically informed historical explanations of our moral endorsements do not involve an appeal to mind-independent truths. I conclude, therefore, that the empirical considerations relevant for the strongest empirically driven argument against moral realism go beyond the strictly evolutionary realm; debunkers are best advised to draw upon other sources of genealogical knowledge as well.
