Putnam's argument that we are not brains in a VAT has recently seen a resurgence in interest. Although objections to it are legion, an emerging consensus seems to be that even if it successfully refutes one version of the brain in a VAT scenario, lifelong envatment, it is powerless against a different one, recent envatment. Although initially appealing, I argue in this paper that this response-merely replacing lifelong envatment by recent envatment-is a bad response to Putnam's argument. Yet (...) there is a different version of the brain in a VAT scenario, recent memory-altering envatment, that Putnam's argument does not refute and is also sufficiently radical. The crucial issue turns out to be which epistemic sources sceptical scenarios may attack. I argue that there's no convincing reason for exempting memory from the sceptical attack: Sceptical scenarios must target memory to be sufficiently radical and they can do so without violating any constraint on sceptical scenarios. In the end Putnam's argument doesn't fail because of some 'deep' philosophical mistake, but because it overlooks how flexible and adjustable sceptical scenarios are. (shrink)

Putnam famously attempted to use model theory to draw metaphysical conclusions. His Skolemisation argument sought to show metaphysical realists that their favourite theories have countable models. His permutation argument sought to show that they have permuted models. His constructivisation argument sought to show that any empirical evidence is compatible with the Axiom of Constructibility. Here, I examine the metamathematics of all three model-theoretic arguments, and I argue against Bays (2001, 2007) that Putnam is largely immune to metamathematical challenges.

Tim Button explores the relationship between words and world; between semantics and scepticism. -/- A certain kind of philosopher – the external realist – worries that appearances might be radically deceptive. For example, she allows that we might all be brains in vats, stimulated by an infernal machine. But anyone who entertains the possibility of radical deception must also entertain a further worry: that all of our thoughts are totally contentless. That worry is just incoherent. -/- We cannot, then, be (...) external realists, who worry about the possibility of radical deception. Equally, however, we cannot be internal realists, who reject all possibility of deception. We must position ourselves somewhere between internal realism and external realism, but we cannot hope to say exactly where. We must be realists, for what that is worth, and realists within limits. -/- In establishing these claims, The Limits of Realism critically explores and develops several themes from Hilary Putnam’s work: the model-theoretic arguments; the connection between truth and justification; the brain-in-vat argument; semantic externalism; and conceptual relativity. The book establishes the continued significance of these topics for all philosophers interested in mind, logic, language, or the possibility of metaphysics. (shrink)

The celebrated "Twin Earth" arguments of Hilary Putnam (1975) and Tyler Burge (1979) aim to establish that some intentional states logically depend on facts external to the subjects of those states. Ascriptions of states of these kinds to a thinker entail that the thinker's environment is a certain way. It is not possible that the thinker could be in those very intentional states unless the environment is that way...

In “Models and Reality” (1980), Putnam sketched a version of his internal realism as it might arise in the philosophy of mathematics. Here, I will develop that sketch. By combining Putnam’s model-theoretic arguments with Dummett’s reflections on Gödelian incompleteness, we arrive at (what I call) the Skolem-Gödel Antinomy. In brief: our mathematical concepts are perfectly precise; however, these perfectly precise mathematical concepts are manifested and acquired via a formal theory, which is understood in terms of a computable system (...) of proof, and hence is incomplete. Whilst this might initially seem strange, I show how internal categoricity results for arithmetic and set theory allow us to face up to this Antinomy. This also allows us to understand why “Models are not lost noumenal waifs looking for someone to name them,” but “constructions within our theory itself,” with “names from birth.”. (shrink)

Philosophers of mind typically conduct their discussions in terms of mental events, mental processes, mental properties, mental states – but rarely in terms of minds themselves. Sometimes this neglect is explicitly acknowledged. Donald Davidson, for example, writes that ‘there are no such things as minds, but people have mental properties, which is to say that certain psychological predicates are true of them. These properties are constantly changing, and such changes are mental events’.2 Hilary Putnam agrees, though for somewhat different (...) reasons: The view I have long defended is that the mind is not a thing; talk of our minds is talk of world-involving capabilities that we have and activities that we engage in. As Dewey succinctly put it, “Mind is primarily a verb. It denotes all the ways in which we deal consciously and expressly with the situation in which we find ourselves. Unfortunately, an influential manner of thinking has changed modes of action into an underlying substance that performs the activities in question. It has treated mind as an independent entity which attends, purposes, cares and remembers”. But the traditional view, by treating mental states as states of the “underlying substance”, makes them properties of something “inside”, and, if one is a materialist philosopher, that means properties of our brains. So the next problem naturally seems to be: “Which neurological properties of our brains do these mental properties ‘reduce’ to?” For how could our brains have properties that aren’t neurological? And this is how materialist philosophers saw the problem until the advent of such new alternatives in the philosophy of mind and philosophy of language as Functionalism and Semantic Externalism.

Reading Putnam consists largely of papers from the fantastic ‘Putnam @80’ conference (organised by Maria Baghramian in 2007) together with replies from Hilary Putnam. Given the diversity of Putnam’s work, the papers in this collection cover many different topics. This makes the collection difficulty to read but, ultimately, extremely rewarding. In this review, I focus on the contributions from Michael Devitt, Charles Parsons, Richard Boyd, Ned Block, Charles Travis and John McDowell, together with Putnam’s responses. (...) My aim is to highlight some connections between Putnam’s (evolving) views on ontology, conceptual relativism, and perception. (shrink)

Hilary Putnam’s Realism with a Human Face began with a quotation from Rilke, exhorting us to ‘try to love the questions themselves like locked rooms and like books that are written in a very foreign tongue’. Putnam followed this advice throughout his life. His love for the questions permanently changed how we understand them. In Naturalism, Realism, and Normativity – published only a few weeks after his death – Putnam continued to explore central questions concerning realism and (...) perception, from the perspective of ‘liberal naturalism’. The volume’s thirteen papers were written over the past fifteen years (only one paper is new), and they show a man who fully inhabited the questions he loved. And the main significance of this book is that it shows – implicitly, but very clearly – quite how much of Putnam’s contribution to his philosophy is continuous with his ‘The Meaning of “Meaning”’.

Putnam’s most famous contribution to mathematical logic was his role in investigating Hilbert’s Tenth Problem; Putnam is the ‘P’ in the MRDP Theorem. This volume, though, focusses mostly on Putnam’s work on the philosophy of logic and mathematics. It is a somewhat bumpy ride. Of the twelve papers, two scarcely mention Putnam. Three others focus primarily on Putnam’s ‘Mathematics without foundations’ (1967), but with no interplay between them. The remaining seven papers apparently tackle unrelated themes. (...) Some of this disjointedness would doubtless have been addressed, if Putnam had been able to compose his replies to these papers; sadly, he died before this was possible. In this review, I do my best to tease out some connections between the paper; and there are some really interesting connections to be made. (shrink)

Hilary Putnam’s BIV argument first occurred to him when ‘thinking about a theorem in modern logic, the “Skolem–Löwenheim Theorem”’ (Putnam 1981: 7). One of my aims in this paper is to explore the connection between the argument and the Theorem. But I also want to draw some further connections. In particular, I think that Putnam’s BIV argument provides us with an impressively versatile template for dealing with sceptical challenges. Indeed, this template allows us to unify some of (...) Putnam’s most enduring contributions to the realism/antirealism debate: his discussions of brains-in-vats, of Skolem’s Paradox, and of permutations. In all three cases, we have an argument which does not merely defeat the sceptic; it also shows us that we must reject some prima facie plausible philosophical picture. (shrink)

Hilary Putnam once suggested that “the actual existence of sets as ‘intangible objects’ suffers… from a generalization of a problem first pointed out by Paul Benacerraf… are sets a kind of function or are functions a sort of set?” Sadly, he did not elaborate; my aim, here, is to do so on his behalf. There are well-known methods for treating sets as functions and functions as sets. But these do not raise any obvious philosophical or foundational puzzles. For that, (...) we first need to provide a full-fledged function theory. I supply such a theory: it axiomatizes the iterative notion of function in exactly the same sense that ZF axiomatizes the iterative notion of set. Indeed, this function theory is synonymous with ZF. It might seem that set theory and function theory present us with rival foundations for mathematics, since they postulate different ontologies. But appearances are deceptive. Set theory and function theory provide the very same judicial foundation for mathematics. They do not supply rival metaphysical foundations; indeed, if they supply metaphysical foundations at all, then they supply the very same metaphysical foundations. (shrink)

In his book Elements of mind Tim Crane has developed some resources in order to answer the Twin Earth mental experiment, invented by Hilary Putnam. The aim of this paper is to demonstrate that Crane’s strategy is ineffective because he misunderstands that argument. We intend to examine in detail the reconstruction of the argument that Crane offers to detect its problems. A tighter version of it is also proposed, more consistent with Putnam intentions.

In an analysis of the role of emotion in self-deception is presented. It is argued that instances of emotional self-deception unproblematically meet Mele's jointly sufficient criteria. It is further proposed that a consideration of different forms of mental representation allows the possibility of instances of self-deception in which contradictory beliefs (in the form p and ~p) are held simultaneously with full awareness.

Quine has spoken of bringing our beliefs about the world before “the tribunal of experience.” In Mind and World, McDowell agrees that this is what we must do, but he argues forcefully that Quine’s conception of experience as nothing more than a neuronal cause of verbal responses loses the whole idea that experiences can justify beliefs. McDowell’s overarching aim is to determine conditions that experience must satisfy if it is to be genuinely a tribunal.

In this article I defend the view that many central aspects of the semantics of tense are determined by independently-motivated principles of syntactic theory. I begin by decomposing tenses syntactically into a temporal ordering predicate (the true tense, on this approach) and two time-denoting arguments corresponding to covert a reference time (RT) argument and an eventuality time (ET) argument containing the verb phrase. Control theory accounts for the denotation of the RT argument, deriving the distinction between main clause and subordinate (...) clause tenses. The theory of covert movement is used to account for the independent/indexical interpretation of relative clause tenses, and for the correlation between independent tense interpretation and a de re construal of the relative clause. A theory of “past polarity”, based on traditional negative polarity theory, accounts both for the simultaneous “sequence of tense” construal of past tenses in subordinate clauses embedded within past tense contexts, and for the obligatory indexical/independent interpretation of present tense in a relative clause embedded within a past tense context. Combined with the copy theory of movement, the polarity theory also provides an account of the semantics of double access sentences, treating them as involving a special kind of reconstruction effect.

According to a Moorean response to skepticism, the standards for knowledge are invariantly comparatively low, and we can know across contexts all that we ordinarily take ourselves to know. It is incumbent upon the Moorean to defend his position by explaining how, in contexts in which S seems to lack knowledge, S can nevertheless have knowledge. The explanation proposed here relies on a warranted-assertability maneuver: Because we are warranted in asserting that S doesn’t know that p, it can seem that (...) S does in fact lack that piece of knowledge. Moreover, this warranted-assertability maneuver is unique and better than similar maneuvers because it makes use of H. P. Grice’s general conversational rule of Quantity—“Do not make your contribution more informative than is required”—in explaining why we are warranted in asserting that S doesn’t know that p. (shrink)

Drawing on the author's recent bookEthics for a Broken World, this article explores the philosophical implications of the fact that climate change – or something like it – might lead to abroken worldwhere resources are insufficient to meet everyone's basic needs, and where our affluent way of life is no longer an option. It argues that the broken world has an impact, not only on applied ethics, but also on moral theory. It then explores that impact. The article first argues (...) that the broken world creates severe difficulties for both libertarians and contractualists. It then explores the impact of the broken world on utilitarianism – and especially on reflective equilibrium arguments for rule-utilitarianism. The article concludes that, while such arguments may still be viable, the form of rule-utilitarianism that results will be less moderate and less liberal than contemporary rule-utilitarians might hope.

I offer an account of perceptual warrant according to which one’s basic perceptual beliefs are immediately and defeasibly warranted if they are formed on the basis of experiences produced by a competent perceptual system. I claim that sub-personal features of one’s perceptual systems can render one competent to perceptually represent a particular environment. When these conditions are met, one is warranted in forming beliefs on the basis of one’s perceptual experiences. I develop my account of perceptual warrant in the context (...) of a Bayesian theory of perceptual processing. (shrink)

Our everyday notions of responsibility are often driven by our need to justify ourselves to specific others – especially those we harm, wrong, or otherwise affect. One challenge for contemporary ethics is to extend this interpersonal urgency to our relations with those future people who are harmed or affected by our actions. In this article, I explore our responsibility for climate change by imagining a possible ‘broken future’, damaged by the carbon emissions of previous generations, and then asking what its (...) inhabitants might think of our current behaviour, our moral thinking, and our excuses. In particular, I will focus on a simplified scenario where present people can only avoid a broken future by sacrificing Rawlsian favourable conditions. Suppose we refuse to avoid a broken future, on the grounds that we cannot be expected to make such great sacrifices. If the broken future lacks favourable conditions, will its inhabitants accept our excuses? Will they hold us responsible for things we regard as excusable? If so, should we be guided by their judgements or by our own? (shrink)

This paper discusses a role playing ethics case suitable for business students in which participants must balance shareholder and stakeholder concerns. Students take on the role of operations manager and are challenged to consider the effects of their choices on the local society as they balance the demands of stockholders, employees, and family when the concerns of the groups come into conflict. The exercise helps students understand the need to consider the ethicalcomponents of business decisions and the difficulties of handling (...) values in conflict. Students learn more about their own values through playing the role of manager. Suggested discussion questions are provided. This note also reviews some of the extant literature on the goals of stakeholder versus shareholder wealth and the role of ethics, and it discusses areas of common ground between the stakeholder/shareholder theories.

Jakob von Uexküll’s (1864-1944) account of Umwelt has been proposed as a mediating concept to bridge the gap between ecological psychology’s realism about environmental information and enactivism’s emphasis on the organism’s active role in constructing the meaningful world it inhabits. If successful, this move would constitute a significant step towards establishing a single ecological-enactive framework for cognitive science. However, Uexküll’s thought itself contains different perspectives that are in tension with each other, and the concept of Umwelt is developed in representationalist (...) terms that conflict with the commitments of both enactivism and ecological psychology. One central issue shared by all these approaches is the problem of how a living being experiences its environment. In this paper, we will look at Uexküll’s reception in French philosophy and highlight the different ways in which the concept of Umwelt functions in the work of Georges Canguilhem, Maurice Merleau-Ponty, and Gilles Deleuze. This analysis helps clarify different aspects of Uexküll’s thought and the deeper philosophical implications of importing his concepts into embodied cognitive science. This paper is part of a recent trend in which enactivism engages with continental philosophy in a way that both deepens and transcends the traditional links to phenomenology, including most recently the thought of Georg W. F. Hegel and Gilbert Simondon. However, no more than a brief outline and introduction to the potentials and challenges of this complex conceptual intersection can be given here. Our hope is that it serves to make more explicit the philosophical issues that are at stake for cognitive science in the question of experienced environments, while charting a useful course for future research.

In the beginning of the 1970s, Michel Foucault dismisses the terminology of ‘exclusion’ for his projected analytics of modern power. This rejection has had major repercussions on the theory of neoliberal subject-formation. Many researchers disproportionately stress how neoliberal dispositifs produce entrepreneurial subjects, albeit in different ways, while minimizing how these dispositifs sometimes emphatically refuse to produce neoliberal subjects. Relying on Saskia Sassen’s work on financialization, I argue that neoliberal dispositifs not only apply entrepreneurial norms, but also suspend their application for (...) groups that threaten to harm the population’s profitability. Neoliberal dispositifs not only produce entrepreneurial subjects, but also surplus populations that are expelled from the overall population to maintain its productivity. Here, the concept of ‘exclusion’ is appropriate if understood in Agamben’s sense of an inclusive exclusion. The surplus population is part of neoliberal dispositifs, but only as the element to be abandoned. (shrink)

Systems of private regulation based on certification have recently emerged to address environmental issues in the forest products industry and labor issues in the apparel industry. To explain why the same regulatory form has emerged across these fields, the author uses a historical and comparative case study approach, closely examining early moments and paying attention to “roads not taken.” Two types of factors led to the initial emergence of private certification: social movement campaigns targeting companies and a neo-liberal institutional context. (...) The analysis shows specific ways in which these factors led states, nongovernmental organizations, and companies to build or support certification associations. (shrink)

Jessica Brown effectively contends that Keith DeRose’s latest argument for contextualism fails to rule out contextualism’s chief rival, namely, classic invariantism. Still, even if her position has not been ruled out, the classic invariantist must offer considerations in favor of her position if she is to convince us that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability maneuver that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this maneuver is not as effective (...) as it might be. I propose a different warranted assertability maneuver—one that utilizes a pragmatic principle of strength—that affords a more successful defense of classic invariantism, and that helps to establish that classic invariantism is superior to contextualism.

The “surge in use of finite-state methods” ([10]) in computational linguistics has largely, if not completely, left semantics untouched. The present paper is directed towards correcting this situation. Techniques explained in [1] are applied to a fragment of temporal semantics through an approach we call finite-state temporality. This proceeds from the intuition of an event as “a series of snapshots” ([15]; see also [12]), equating snapshots with symbols that collectively form our alphabet. A sequence of snapshots then becomes a string (...) over that alphabet, evoking comic/film strips. Jackendoff has, among others, objected to conceptualizing events in terms of snapshots ([8]). To counter these objections, we step up from events-as-strings to event-typesas-regular languages ([5, 6]), recognizing the need for variable granularity. Beyond the introduction of disjunction implicit in the step from a single string up to a set of strings, we obtain a useful logic from the regular operations and a careful choice of the snapshots (constituting our alphabet).

In a memorable passage near the beginning of William James asks us to imagine a world in which all our dearest social utopias are realized, and then to imagine that this world is offered to us at the price of one lost soul at the farthest edge of the universe suffering eternal, intense, lonely pain. Then he asks.

This is the first volume to address directly the question of the speciation of modern Homo sapiens. The subject raises profound questions about the nature of the species, our defining characteristic, and the brain changes and their genetic basis that make us distinct. The British Academy and the Academy of Medical Sciences have brought together experts from palaeontology, archaeology, linguistics, psychology, genetics and evolutionary theory to present evidence and theories at the cutting edge of our understanding of these issues.Palaeontological and (...) genetic work suggests that the transition from a precursor hominid species to modern man took place between 100,000 and 150,000 years ago. Some contributors discuss what is most characteristic of the species, focussing on language and its possible basis in brain lateralization. This work is placed in the context of speciation theory, which has remained a subject of considerable debate since the evolutionary synthesis of Mendelian genetics and Darwinian theory. The timing of specific transitions in hominid evolution is discussed, as also is the question of the neural basis of language. Other contributors address the possible genetic nature of the transition, with reference to changes on the X and Y chromosomes that may account for sex differences in lateralization and verbal ability. These differences are discussed in terms of the theory of sexual selection, and with reference to the mechanisms of speciation.These essays will be vital reading for anyone interested in the nature and origins of the species, and specifically human abilities.

A major problem that skeptical critics have identified with the project of environmental ethics as it is often conceived is that it involves the search for a criterion of moral considerability, and some claim that this search has not only been unsuccessful, but it is in principle mistaken. Birch has recently argued that this whole problem can be avoided through his proposal of universal consideration in a “root sense,” which applies to all beings, with no exceptions marked by any of (...) the criteria proposed by others. I argue that the strengths of this proposal are its openness to new value discoveries and its focus on agents’ practices. Its flaw is its failure to account convincingly for how values are ever formulated or obligations generated. Hence, it does not represent a viable alternative to the approach he rejects. However, rather than return to that approach, I suggest that Birch’s own line of argument could be developed more consistently if, from his starting point of “deontic experience,” one were to develop an explicitly deontological ethic that focuses more decisively on moral consideration as opposed to moral considerability.
