EMPIRICISM FOR CYBORGS

One important debate between scientific realists and constructive empiricists concerns whether we observe things using instruments. This paper offers a new perspective on the debate over instruments by looking to recent discussion in philosophy of mind and cognitive science. Realists often speak of instruments as ‘extensions’ to our senses. I ask whether the realist may strengthen her view by drawing on the extended mind thesis. Proponents of the extended mind thesis claim that cognitive processes can sometimes extend beyond our brains and bodies into the environment. I suggest that the extended mind thesis offers a way to make sense of realists’ talk of instruments as extensions to the senses and that it provides the realist with a new argument against the constructive empiricist view of instruments.     

Two Concepts of Basic Equality

It has become somewhat a commonplace in recent political philosophy to remark that all plausible political theories must share at least one fundamental premise, ‘that all humans are one another's equals’. One single concept of ‘basic equality’, therefore, is cast as the common touchstone of all contemporary political thought. This paper argues that this claim is false. Virtually all do indeed say that all humans are ‘equals’ in some basic sense. However, this is not the same sense. There are not one but (at least) two concepts of basic equality, and they reflect not a grand unity within political philosophy but a deep and striking division. I call these concepts ‘Equal Worth’ and ‘Equal Authority’. The former means that each individual’s good is of equal moral worth. The latter means that no individual is under the natural authority of anyone else. Whilst these two predicates are not in themselves logically inconsistent, I demonstrate that they are inconsistent foundation stones for political theory. A theory that starts from Equal Worth will find it near impossible to justify Equal Authority. And a theory that starts from Equal Authority will find any fact about the true worth of things, including ourselves, irrelevant to justifying legitimate action. This helps us identify the origin of many of our deepest and seemingly intractable disagreements within political philosophy, and directs our attention to the need for a clear debate about the truth and/or relationship between the two concepts. In short, my call to arms can be summed up in the demand that political philosophers never again be allowed to claim ‘that all human beings are equals’ full stop. They must be clear in what dimension they claim that we are equals—Worth or Authority (or perhaps something else).     

Simulation and Irrationality

Abstract

In this paper, I hope to show how a recent theory in the philosophy of mind concerning how we ‘read’ the minds of others—namely, Heal's version of simulation theory—is consistent with the view that the kind of understanding we bring to bear on the irrational is different in kind from the way we understand one another in the course of everyday life. I shall attempt to show that Heal's version of simulation theory (co-cognition) is to be favoured over its rival ‘theory theories’ in the light of its accommodation of deeply irrational mental states. I claim that simulation theory preserves an asymmetry of psychological explanation which is not similarly preserved by a theory theory account, and I argue that this preservation of asymmetry is an advantage of Heal's account.     

At one with our actions,but at two with our bodies

Jennifer Hornsby's account of human action frees us from the temptation to think of the person who acts as ‘doing’ the events that are her actions, and thereby removes much of the allure of ‘agent causation’. But her account is spoiled by the claim that physical actions are ‘tryings’ that cause bodily movements. It would be better to think of physical actions and bodily movements as identical; but Hornsby refuses to do this, seemingly because she thinks that to do so would be to endorse the so–called ‘standard causal story’. But Hornsby misses a possibility here, for we can insist on this identity claim without endorsing the standard story if we embrace an account which parallels the disjunctive account in the philosophy of perception. This will leave us with a picture of physical action that saves the insights of Hornsby's account without succumbing to its distortions.     

The Eschatological Turn in German Philosophy

This article argues that modern European philosophy was significantly shaped by the transposition of eschatology from a theological into a philosophical register. By ‘eschatology’, I here mean thought about the ‘last things’ as they relate to present systems of life and action; and about those systems as determined, at least in part, by their end. I take as my starting point the claim that the scepticism regarding revelation that was such a central characteristic of the Enlightenment did not eradicate the importance of eschatology as a structuring frame of historical and moral thought, but merely changed it. Modern theologians and philosophers tended to shift the ground of eschatology from revelation to the inner logic of a system; eschatology was seen as legitimated by, and in turn legitimating, the shape of a given philosophical account of history. The questions and challenges arising from this shift were important drivers of early twentieth‐century European philosophy. This article works out this claim through indicative accounts of several large debates of early twentieth‐century philosophies of history and of politics as contestations about the meaning of eschatology: the crisis of historicism, the rise of existentialism, and the surge of political religions. It concludes with a discussion of Martin Heidegger’s eschatological thought of the 1930s, illuminated by the recent publication of his Black Notebooks.     

Iconic Representations and Representative Practices

I develop an account of scientific representations building on Charles S. Peirce's rich, and still underexplored, notion of iconicity. Iconic representations occupy a central place in Peirce's philosophy, in his innovative approach to logic and in his practice as a scientist. Starting from a discussion of Peirce's approach to diagrams, I claim that Peirce's own representations are in line with his formulation of iconicity, and that they are more broadly connected to the pragmatist philosophy he developed in parallel with his scientific work. I then defend the contemporary relevance of Peirce's approach to iconic representations, and specifically argue that Peirce offers a useful ‘third way’ between what Mauricio Suárez has recently described as the ‘analytical’ and ‘practical’ inquiries into the concept of representation. As a philosophically minded scientist and an experimentally inclined philosopher, Peirce never divorced the practice of representing from questions about what counts as a representation. I claim that his account of iconic representations shows that it is the very process of representing, construed as a practice which is coextensive with observing and experimenting, that casts light on the nature of representative relations.     

Estrangement,Nature and ‘the Flesh’

In this paper I address the question of what it is to be alienated from nature. The focus is alienation in the sense of estrangement, a ‘being cut off from’ a wider world. That we are so estranged is a claim associated with ecological critique of contemporary society. But what is it to be estranged from nature given that everything we are, do and produce, always remains within a wider nature? I explore the possibility that this might be understood with reference to Merleau-Ponty’s notion of ‘flesh’. I set the scene for this with some discussion of Honneth’s recent account of reification as a ‘distorted praxis’ and then, drawing upon Merleau-Ponty’s phenomenology of perception and especially his later ontology of flesh, develop the idea of estrangement from the natural world as an inadequate participation in a ‘primordial’ perceptual relation. This idea of estrangement brings together various elements of ecological critique. However, I argue that although this idea of estrangement might inform and help to articulate such a critique, it cannot be the sole concern of an environmental political philosophy: other kinds of alienation within the humanised environmental context need to be considered too.     

Inferentialist Philosophy of Language and the Historiography of Philosophy

This article considers the implications of inferentialist philosophy of language for debates in the historiography of philosophy. My intention is to mediate and refine the polemics between contextualist historians and ‘analytic’ or presentist historians. I claim that much of Robert Brandom's nuanced defence of presentism can be accepted and even adopted by contextualists, so that inferentialism turns out to provide an important justification for orthodox history of philosophy. In the concluding sections I argue that the application of Brandom's theory has important limits, and that some polemics by contextualists against presentists are therefore justified.     

Springs,Nitre, and Conatus. The Role of the Heart in Hobbes's Physiology and Animal Locomotion

This paper focuses on an understudied aspect of Hobbes's natural philosophy: his approach to the domain of life. I concentrate on the role assigned by Hobbes to the heart, which occupies a central role in both his account of human physiology (which he names ‘vital motion’) and of the origin of animal locomotion (‘animal or voluntary motion’). With this, I have three goals in mind. First, I aim to offer a cross-section of Hobbes's effort to provide a mechanistic picture of human life. Second, I aim to contextualize Hobbes's views in the seventeenth-century debates on human physiology and animal locomotion. In particular, I will compare Hobbes's views with the theories put forth by Harvey, Descartes, the Galenic, and Peripatetic traditions. Also, I will show that Hobbes was receptive to advances within contemporary English physiology and chemistry. Third, by means of a comparison with Descartes, I advance some hypothesis to explain why Hobbes indentified the heart, and not the brain (as was increasingly common in his day), as the organ originating animal locomotion. In this regard, I trace out some possible implications of Hobbes's views on human physiology and locomotion for his psychology and political philosophy.     

Neither here nor there: the cognitive nature of emotion

The philosophy of emotion has long been divided over the cognitive nature of emotion. In this paper I argue that this debate suffers from deep confusion over the meaning of “cognition” itself. This confusion has in turn obscured critical substantive agreement between the debate’s principal opponents. Capturing this agreement and remedying this confusion requires re-conceptualizing “the cognitive” as it functions in first-order theories of emotion. Correspondingly, a sketch for a new account of cognitivity is offered. However, I also argue that this new account, despite tacit acceptance by all major theories of emotion, in fact rules out some of the most fundamental and controversial claims of one side of the nature-of-emotion debate, emotional cognitivism.     

The Agential Point of View

Agentialist accounts of self‐knowledge seek to do justice to the connection between our identities as rational agents and our capacity to know our own minds. There are two strategies that agentialists have employed in developing their position: substantive and non‐substantive. My aim is to explicate and defend one particular example of the non‐substantive strategy, namely, that proposed by Tyler Burge. In particular, my concern is to defend Burge's claim that critical reasoning requires a relation of normative directness between reviewing and reviewed perspectives. My defence will involve supplementing Burge's view with a substantive agentialist account of self‐knowledge.     

Contents of Experience

In this paper I aim to situate the Naiyayika theory of perception in contemporary philosophy of mind. Following the ancients, I suggest we reconsider the taxonomy and the assumed interactions between kinds of perceptual content. This reclassification will lead us to reconsider some aspects of the Cartesian conception of mind that continue to influence the work of contemporary theorists. I focus attention on different accounts of sensory perception favoured by ancient Indian Naiyayika philosophers and Descartes as a starting point for reconsidering contemporary accounts of perceptual content.I show that Descartes' account of sensory perception provides the impetus for a causal-explanatory account of conceptual content in terms of its non-conceptual counterpart. Though contemporary philosophers claim to have cast off their Cartesian heritage, my discussion reveals that some of its tenets continue to influence the work of contemporary philosophers. I offer reasons for rejecting yet another Cartesian influence and recommend that we follow the Nyaya taxonomy of perceptual states.     

An application of Carnapian inductive logic to an argument in the philosophy of statistics

I claim that an argument from the philosophy of statistics can be improved by using Carnapian inductive logic. Gelman and Shalizi [9] criticise a philosophical account of how statisticians ought to choose statistical models which they call ‘the received view of Bayesian inference’ and propose a different account inspired by falsificationist philosophy of science. I introduce another philosophical account inspired by Carnapian inductive logic and argue that it is even better than Gelman and Shalizi's falsificationist account.     

Tyler Burge on disjunctivism (II)

In McDowell (2010), I responded to Burge's attack (2005) on disjunctivism. In Burge (2011) Burge rejects my response. He stands by his main claim that disjunctivism is incompatible with the science of perception, and in a supplementary spirit he argues against the detail of my attempt to defend disjunctivism. Here I explain how disjunctivism is compatible with the science, and I respond to some of Burge's supplementary arguments.     

Collingwood and Ryle on the Concept of Mind

Abstract

This paper argues that Collingwood's philosophy of mind offers an interesting and compelling account of the nature of the mind and of the irreducibility of the mental, an account whose viability and relevance to contemporary debates ought to be given serious consideration. I suggest that the reason why Collingwood's contribution to the philosophy of mind has been neglected is due to the fact that his philosophy of mind is widely, even if mistakenly, regarded as the target of Ryle's attacks on the dogma of the ghost in the machine and proceed to undermine the assumption that Collingwood is a twentieth century adherent of the dogma.     

Putnam's natural realism and the question of a perceptual interface

According to Hilary Putnam, natural realism is a form of direct realism in the philosophy of perception that promises to help see us past an irresolvable metaphysical dispute between realism and anti-realism. Illumination depends upon the claim that in perception that there is no interface between the cognitive powers of the mind and the causal powers of the world. In the present paper I aim to show that there is a hidden complexity in Putnam's notion of a perceptual interface. On a trivializing reading, Putnam intends only to reject a modern materialist version of the traditional ‘veil of ideas’. On a richer reading, he intends also to reject the view that the intentional content of experience is autonomous with respect to the external world. I conclude by suggesting that natural realism is not mere common sense and that its fate is tied to its ability to respond to the skeptical threats that help to motivate the traditional options of realism and antirealism.     

On Sellars' exam question trilemma: are Kant's premises analytic,or synthetic a priori,or a posteriori?

ABSTRACT

Wilfrid Sellars argued that Kant’s account of the conceptual structures involved in experience can be given a linguistic turn so as to provide an analytic account of the resources a language must have in order to be the bearer of empirical knowledge. In this paper I examine the methodological aspects of Kant’s transcendental philosophy that Sellars took to be fundamental to influential themes in his own philosophy. My first aim here is to clarify and argue for the plausibility of what I claim is Sellars’ interpretation of Kant’s ‘analytic’ transcendental method in the first Critique, based ultimately on non-trivial analytic truths concerning the concept of an object of our possible experience. Kant’s ‘transcendental proofs’ thereby avoid a certain methodological trilemma confronting the candidate premises of any such proof, taken from Sellars’ 1970s undergraduate exam question on Kant. In part II of the essay I conclude by highlighting in general terms how Kant’s method, as interpreted in the analytic manner explained in part I, was adapted by Sellars to produce some of the more influential aspects of his own philosophy, expressed in terms of what he contends is their sustainable reformulation in light of the so-called linguistic turn in twentieth-century philosophy.     

Searle on Consciousness: or How not to Be a Physicalist

In The Rediscovery of the Mind , John Searle offers a novel theory of consciousness that attempts to overcome the traditional debates within the philosophy of mind between dualism and materialism. Searle maintains that one can be a thoroughgoing materialist without denying the existence of mental phenomena that are inherently subjective in nature. In this paper I argue that Searle's view does not so easily bypass the traditional philosophical debate between materialism and dualism, and, indeed, that Searle's attempt to have it both ways is inconsistent. More specifically, I examine Searle's discussion of the causal reducibility of consciousness and his claim that consciousness is just another property of certain biological systems and argue that in both cases Searle has failed to show that consciousness can be both irreducibly subjective and a normal physical feature of the brain.     

How the World Is Measured Up in Size Experience

I develop a Russellian representationalist account of size experience that draws importantly from contemporary vision science research on size perception. The core view is that size is experienced in ‘body‐scaled’ units. So, an object might, say, be experienced as two eye‐level units high. The view is sharpened in response to Thompson’s (forthcoming) Doubled Earth example. This example is presented by Thompson as part of an argument for a Fregean view of size experience. But I argue that the Russellian view I develop handles the Doubled Earth example in a natural and illuminating way, thereby avoiding the need to posit irreducible experiential ‘modes of presentation’. I also address a kind of neo‐Fregean ‘reference‐fixing’ view of size experience, that shares features with the Russellian view developed. I give reasons for favoring the latter. Finally, I argue that Peacocke’s claim that spatial experience is ‘unit free’ is not persuasive.
