This essay explains Kant’s idea of autonomy of the will and advances a thesis about how it emerges in his moral conception. Kant defines “autonomy” as “the property of the will by which it is a law to itself…” and argues that the Categorical Imperative is that law. I take the autonomy of the will to mean that the nature of rational volition is the source of the formal principle that authoritatively governs rational volition. I give a sense to this (...) idea by pointing to an argument form found throughout the Groundwork and the second Critique where Kant moves from a conception of rational volition as a faculty to a statement of its formal principle. This idea of autonomy emerges in Kant’s moral conception (at the time he writes the Groundwork) as his solution to the problem of moral theory. Common sense assumes that moral requirements apply with unconditional necessity, and the problem of moral theory is to show how such requirements are possible. Kant’s resolution to this problem is to argue that the necessity of moral requirement is genuine only if based in autonomy of the will, only if based in a “law that arises from one’s will”. (shrink)

A very simple contextualist treatment of a sentence containing an epistemic modal, e.g. a might be F, is that it is true iff for all the contextually salient community knows, a is F. It is widely agreed that the simple theory will not work in some cases, but the counterexamples produced so far seem amenable to a more complicated contextualist theory. We argue, however, that no contextualist theory can capture the evaluations speakers naturally make of sentences containing epistemic modals. If (...) we want to respect these evaluations, our best option is a relativist theory of epistemic modals. On a relativist theory, an utterance of a might be F can be true relative to one context of evaluation and false relative to another. We argue that such a theory does better than any rival approach at capturing all the behaviour of epistemic modals. (shrink)

In treating cognition as problem solving, Andy Clark suggests, we may often abstract too far from the very body and world in which our brains evolved to guide...

There is a lot that we don't know. That means that there are a lot of possibilities that are, epistemically speaking, open. For instance, we don't know whether it rained in Seattle yesterday. So, for us at least, there is an epistemic possibility where it rained in Seattle yesterday, and one where it did not. What are these epistemic possibilities? They do not match up with metaphysical possibilities - there are various cases where something is epistemically possible but not metaphysically (...) possible, and vice versa. How do we understand the semantics of statements of epistemic modality? The ten new essays in this volume explore various answers to these questions, including those offered by contextualism, relativism, and expressivism. (shrink)

“There’s no disputing about taste.” That’s got a nice ring to it, but it’s not quite the ring of truth. While there’s definitely something right about the aphorism – there’s a reason why it is, after all, an aphorism, and why its utterance tends to produce so much nodding of heads and muttering of “just so” and “yes, quite” – it’s surprisingly difficult to put one’s finger on just what the truth in the neighborhood is, exactly. One thing that’s pretty (...) clear is that what’s right about the aphorism, that there’s no disputing about taste, isn’t that there’s no disputing about taste. There’s heaps of disputing about taste. People engage in disputes about which movies, music, paintings, literature, meals, furniture, architectural styles, etc. are good, beautiful, tasty, fun, elegant, ugly, disgusting, etc. all the time. This is obvious to anyone who has watched dueling-movie-critics shows, read theater reviews, or negotiated with a group or partner about which movie or restaurant to go to, or which sofa or painting to put in the living room. It takes great care and good aim to fling a brick without hitting somebody who’s engaged in a dispute about taste. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

Subjects with delusions profess to believe some extremely peculiar things. Patients with Capgras delusion sincerely assert that, for example, their spouses have been replaced by impostors. Patients with Cotard’s delusion sincerely assert that they are dead. Many philosophers and psychologists are hesitant to say that delusional subjects genuinely believe the contents of their delusions.2 One way to reinterpret delusional subjects is to say that we’ve misidentified the content of the problematic belief. So for example, rather than believing that his wife (...) is has been replaced by an impostor, we might say that the victim of Capgras delusion believes that it is, in some respects, as if his wife has been replaced by an impostor. Another is to say that we’ve misidentified the attitude that the delusional subject bears to the content of their delusion. So for example, Gregory Currie and co-authors have suggested that rather than believing that his wife has been replaced by an impostor, we should say that the victim of Capgras delusion merely imagines that his wife has been replaced by an impostor.3.

We seem, or so it seems to some theorists, to experience a rich stream of highly detailed information concerning an extensive part of our current visual surroundings. But this appearance, it has been suggested, is in some way illusory. Our brains do not command richly detailed internal models of the current scene. Our seeings, it seems, are not all that they seem. This, then, is the Grand Illusion. We think we see much more than we actually do. In this paper (...) I shall (briefly) rehearse the empirical evidence for this rather startling claim, and then critically examine a variety of responses. One especially interesting response is a development of the so-called ‘skill theory’, according to which there is no illusion after all. Instead, so the theory goes, we establish the required visual contact with our world by an ongoing process of active exploration, in which the world acts as a kind of reliable, interrogable, external memory (Noe, Pessoa and.

Andrews Reath presents a selection of his best essays on various features of Kant's moral psychology and moral theory, with particular emphasis on his conception of rational agency and his conception of autonomy. Together the essays articulate Reath's original approach to Kant's views about human autonomy, which explains Kant's belief that objective moral requirements are based on principles we choose for ourselves. With two new papers, and revised versions of several others, the volume will be of great interest to all (...) students and scholars of Kant and of moral philosophy. (shrink)

The moral status of animals is a subject of controversy both within and beyond academic philosophy, especially regarding the question of whether and when it is ethical to eat meat. A commitment to animal rights and related notions of animal protection is often thought to entail a plant-based diet, but recent philosophical work challenges this view by arguing that, even if animals warrant a high degree of moral standing, we are permitted - or even obliged - to eat meat. (...) class='Hi'>Andy Lamey provides critical analysis of past and present dialogues surrounding animal rights, discussing topics including plant agriculture, animal cognition, and in vitro meat. He documents the trend toward a new kind of omnivorism that justifies meat-eating within a framework of animal protection, and evaluates for the first time which forms of this new omnivorism can be ethically justified, providing crucial guidance for philosophers as well as researchers in culture and agriculture.

I think that there are good reasons to adopt a relativist semantics for epistemic modal claims such as ``the treasure might be under the palm tree'', according to which such utterances determine a truth value relative to something finer-grained than just a world (or a <world, time> pair). Anyone who is inclined to relativise truth to more than just worlds and times faces a problem about assertion. It's easy to be puzzled about just what purpose would be served by assertions (...) of this kind, and how to understand what we'd be up to in our use of sentences like ``the treasure might be under the palm tree'', if they have such peculiar truth conditions. After providing a very quick argument to motivate a relativist view of epistemic modals, I bring out and attempt to resolve this problem in making sense of the role of assertions with relativist truth conditions. Solving this problem should be helpful in two ways: first, it eliminates an apparently forceful objection to relativism, and second, spelling out the relativist account of assertion and communication will help to make clear just what the relativist position is, exactly, and why it's interesting.

The notion of a global state of consciousness is an increasingly important construct in the science of consciousness. However, exactly what a global state of consciousness is remains poorly understood. In this paper I offer an account of global states of consciousness as consciousness-related capacity modulations. On this view global states are not themselves phenomenal states – they are not occurring experiences. Rather, they are states that specify which of a creature’s overall consciousness-related capacities are currently online. Given that the (...) search for the neural correlates of consciousness, as it is currently conceived, is the search for the neural basis of occurrent experiences, the NCC framework is incapable of revealing the neural basis of global states. As such, a mature science of consciousness will need to move beyond the search for NCCs, as that project is currently conceived. (shrink)

I have two main objectives in this essay: (1) to situate the events of 11 September within the context of the impact of modernization on religious consciousness and institutions; and (2) to suggest, albeit without adequate empirical support, that militant Islamic opposition to the West in general and the United States in particular is itself an effect of the peculiar path of modernization that has unfolded in the Gulf region of the Middle East over the last 200 years. To develop (...) my argument, I draw upon Habermas's theory of social evolution. Since this strategy requires explaining the key components of that theory, I devote a good part of the article to this task. The paper has five parts. In parts one and two, I criticize competing explanations of the events of 11 September from left, right and center. All these positions fail in one way or another to take seriously the religious significance of those events. In part three, I explain the six central dimensions of Habermas's theory of social evolution: (1) communicative rationality; (2) communicative action; (3) life-world; (4) system; (5) social typology; and (6) the systemic colonization of the life-world. In part four, I examine the relation between religion and modernity. In part five, I examine the modernization processes in the Gulf region of the Middle East. Empirical evidence tentatively suggests that such a process has been one-dimensional, focusing on systemic complexity to the detriment of the communicative rationalization of the life-world. Such evidence also indicates the existence of widespread systemic colonization of the life-world. If the empirical data are correct, then we can explain the emergence of extreme militant Islamic fundamentalism as an effect of a retarded development of those socio-political structures necessary for the realization of communicative rationality.

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

This paper develops an interpretation of what is essential to kant's doctrine of the highest good, Which defends it while also explaining why it is often rejected. While it is commonly viewed as a theological ideal in which happiness is proportioned to virtue, The paper gives an account in which neither feature appears. The highest good is best understood as a state of affairs to be achieved through human agency, Containing the moral perfection of all individuals and the satisfaction of (...) their permissible ends-I.E., One in which all act from the moral law and in doing so achieve their intended ends. The paper shows that the texts contain two distinct conceptions not distinguished by kant-Both a theological and a secular (political) notion. The standard objections apply to the theological, But the secular conception is consistent with kant's conception of moral conduct. Moreover, That the highest good is introduced as an end to be constructed out of the moral law indicates that the secular version is the essential notion. (shrink)

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours (...) to be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define "the predictive brain." What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

Is moral constructivism an account of the basis of the content of morality or of its authority? In fact, different writers have understood constructivism to be addressing different issues. In this paper I argue that Kant should be understood as a constructivist about the content of morality – or better about a limited set of general substantive principles – and as a constititutivist about its authority. After some general remarks in Section 1 about contemporary discussions of constructivism, in Section 2 (...) I discuss Rawls’s understanding of Kant’s constructivism; Rawls takes Kantian constructivism to be a view about the content of morality. In Section 3, I give an overview of Kant’s moral conception as constructivist about the content of morality and as constitutivist about its authority. In Section 4 I address a worry whether certain features of Kant’s constitutivism rest his constructivism on a realist foundation, arguing that they do not. (shrink)

I argue that a theory according to which some of the content of perception is self-locating gives us the resources to cash out the central thought behind projectivism, without having to go in for an error theory about the projected qualities. I first survey some of the phenomena that might motivate what I take to be the central projectivist thought, and then look at some ways of cashing out just what it would amount to for the thought to be correct. (...) I make some objections to some of the standard sorts of projectivist accounts, and then advocate another way of cashing out the thought that I think, at least in certain cases, does a better job of both capturing the phenomena and underwriting the projectivist idea.

Mindware: An Introduction to the Philosophy of Cognitive Science invites readers to join in up-to-the-minute conceptual discussions of the fundamental issues, problems, and opportunities in cognitive science. Written by one of the most renowned scholars in the field, this vivid and engaging introductory text relates the story of the search for a cognitive scientific understanding of mind. This search is presented as a no-holds-barred journey from early work in artificial intelligence, through connectionist (artificial neural network) counter-visions, and on to neuroscience, (...) artificial life, dynamics, and robotics. The journey ends with some wide-ranging and provocative speculation about the complex coadaptive dance between mind, culture, and technology. Each chapter opens with a brief sketch of a major research tradition or perspective, followed by short yet substantial critical discussions dealing with key topics and problems. Ranging across both standard philosophical territory and the landscape of cutting-edge cognitive science, Clark highlights challenging issues in an effort to engage readers in active debate. Topics covered include mental causation; machine intelligence; the nature and status of folk psychology; the hardware/software distinction; emergence; relations between life and mind; the nature of perception, cognition, and action; and the continuity (or otherwise) of high-level human intelligence with other forms of adaptive response. Numerous illustrations, text boxes, and extensive suggestions for further reading enhance the text's utility. Helpful appendices provide background information on dualism, behaviorism, identity theory, consciousness, and more. An exceptional text for introductory and more advanced courses in cognitive science and the philosophy of mind, Mindware is also essential reading for anyone interested in these fascinating and ever-changing fields.

Why do humans reason? Many animals draw inferences, but reasoning—the tendency to produce and respond to reason-giving performances—is biologically unusual, and demands evolutionary explanation. Mercier and Sperber advance our understanding of reason’s adaptive function with their argumentative theory of reason. On this account, the “function of reason is argumentative… to devise and evaluate arguments intended to persuade.” ATR, they argue, helps to explain several well-known cognitive biases. In this paper, I develop a neighboring hypothesis called the intention alignment model and (...) contrast it with ATR. I conjecture that reasoning evolved primarily because it helped social hominins more readily and fully align their intentions. We use reasons to advance various proximal ends, but in the main, we do it to overwrite the beliefs and desires of others: to get others to think like us. Reason afforded our ancestors a powerful way to build and maintain the shared outlooks necessary for a highly collaborative existence. Yes, we sometimes argue so as to gain argumentative advantage over others, or otherwise advantage ourselves at the expense of those we argue with, but more often, we reason in ways that are mutually advantageous. In fact, there are excellent reasons for thinking this must be so. IAM, I suggest, neatly explains the available evidence, while also providing a more coherent account of reason’s origins. (shrink)

Many philosophers (myself included) have been converted to causal decision theory by something like the following line of argument: Evidential decision theory endorses irrational courses of action in a range of examples, and endorses “an irrational policy of managing the news”. These are fatal problems for evidential decision theory. Causal decision theory delivers the right results in the troublesome examples, and does not endorse this kind of irrational news-managing. So we should give up evidential decision theory, and be causal decision (...) theorists instead. Unfortunately, causal decision theory has its own family of problematic examples for which it endorses irrational courses of action, and its own irrational policy that it is committed to endorsing. These are, I think, fatal problems for causal decision theory. I wish that I had another theory to offer in its place. (shrink)

In this book, Andy Mueller examines the ways in which epistemic and practical rationality are intertwined. In the first part, he presents an overview of the contemporary debates about epistemic norms for practical reasoning, and defends the thesis that epistemic rationality can make one practically irrational. Mueller proposes a contextualist account of epistemic norms for practical reasoning and introduces novel epistemic norms pertaining to ends and hope. In the second part Mueller considers current approaches to pragmatic encroachment in epistemology, (...) ultimately arguing in favor of a new principle-based argument for pragmatic encroachment. While the book defends tenets of the knowledge-first programme, one of its main conclusions is thoroughly pragmatist: in an important sense, the practical has primacy over the epistemic. (shrink)

On many of the idealized models of human cognition and behavior in use by philosophers, agents are represented as having a single corpus of beliefs which (a) is consistent and deductively closed, and (b) guides all of their (rational, deliberate, intentional) actions all the time. In graded-belief frameworks, agents are represented as having a single, coherent distribution of credences, which guides all of their (rational, deliberate, intentional) actions all of the time. It's clear that actual human beings don't live up (...) to this idealization. The systems of belief that we in fact have are fragmented. Rather than having a single system of beliefs that guides all of our behavior all of the time, we have a number of distinct, compartmentalized systems of belief, different ones of which drive different aspects of our behavior in different contexts. It's tempting to think that, while of course people are fragmented, it would be better (from the perspective of rationality) if they weren't, and the only reason why our fragmentation is excusable is that we have limited cognitive resources, which prevents us from holding too much information before our minds at a time. Give us enough additional processing capacity, and there'd be no justification for any continued fragmentation. I argue that this is not so. There are good reasons to be fragmented rather than unified, independent of the limitations on our available processing power. In particular, there are ways our belief-forming mechanisms—including our perceptual systems—could be constructed that would make it better to be fragmented than to be unified. And there are reasons to think that some of our belief-forming mechanisms really are constructed that way. (shrink)

There have been few attempts to answer the twin challenges for alethic pluralists to maintain standard accounts of the logical operators and of logical consequence in a sufficiently systematic and precise way. In this paper, I propose an account of logic and semantics on behalf of pluralists that answers both challenges in a sufficiently systematic and precise way. Crucially, the account accommodates mixed atomics, and its first-order extension also accommodates quantified sentences. Accordingly, pluralists can answer all the distinctively logical challenges (...) for their view. (shrink)

Very often, different people, with different constitutions and comic sensibilities, will make divergent, conflicting judgments about the comic properties of a given person, object, or event, on account of those differences in their constitutions and comic sensibilities. And in many such cases, while we are inclined to say that their comic judgments are in conflict, we are not inclined to say that anybody is in error. The comic looks like a poster domain for the phenomenon of faultless disagreement. I argue (...) that the kind of theory that does the best job of accounting for the appearance of faultless disagreement is a de se version of a response-dependence account, according to which thinking that x is funny is self-attributing a property of the type, being disposed to have R to x in C.

This chapter examines Kant's moral philosophy, which is developed principally in three major works: the Groundwork of the Metaphysics of Morals, the Critique of Practical Reason, and The Metaphysics of Morals. It begins with an overview of Kant's foundational theory, and then turns, more briefly, to his normative theory.

Philosophers have highlighted a dilemma for the criminal law. Unjust, racist policies in the United States have produced conditions in which the dispossessed are more likely to commit crime. This complicity undermines the standing of the state to blame their offenses. Nevertheless, the state has reason to punish those crimes in order to deter future offenses. Tommie Shelby proposes a way out of this dilemma. He separates the state’s right to condemn from its right to punish. I raise doubts about (...) Shelby’s proposed resolution. So long as punishment is widely and reasonably understood to condemn crime, Shelby’s proposal does not resolve the dilemma. Moreover, there is reason to think the blaming aspect of punishment plays a role in the justification of its hard treatment. I conclude by considering some other ways out of the dilemma, focusing especially on how the United States might take responsibility for its complicity. (shrink)

Problems about the accidental properties of properties motivate us--force us, I think--not to identify properties with the sets of their instances. If we identify them instead with functions from worlds to extensions, we get a theory of properties that is neutral with respect to disputes over counterpart theory, and we avoid a problem for Lewis's theory of events. Similar problems about the temporary properties of properties motivate us--though this time they probably don't force us--to give up this theory as well, (...) and to identify properties with functions from world, time pairs to extensions. Again, the replacement theory is neutral with respect to a metaphysical dispute that the old theory (arguably) forces us to take a stand on--the dispute over whether objects have temporal parts. It also allows us to give a smoother semantics for predication, to better accommodate our intuitions about which objects temporary properties are properties of, and to make temporally self-locating beliefs genuinely self -locating.

This article brings animal protection theory to bear on Temple Grandin’s work, in her capacity both as a designer of slaughter facilities and as an advocate for omnivorism. Animal protection is a better term for what is often termed animal rights, given that many of the theories grouped under the animal rights label do not extend the concept of rights to animals. I outline the nature of Grandin’s system of humane slaughter as it pertains to cattle. I then outline four (...) arguments Grandin has made defending meat-eating. On a protection-based approach, I argue, Grandin’s system of slaughter is superior to its traditional counterpart. Grandin’s success as a designer of humane slaughterhouses however is not matched by any corresponding success in offering a moral defence of meat-eating. Despite, or perhaps because of, the popularity of her work, Grandin’s arguments for continuing to eat animals are noteworthy only in how disappointing and rudimentary they are. If we can thank Grandin for making a difference in the lives of millions of farm animals, her work can also be criticized for not engaging the moral status of animals with the depth and rigor that it deserves.

This article explores a set of questions about the ‘idea of freedom’ that Kant introduces in the fourth paragraph of Groundwork III. I develop a reading that supports treating it as a normative notion and brings out its normative content in some detail. I argue that we should understand the idea as follows: that it is a general feature of reasoning and judgement that it understands itself to be a correct or sound application of the normative standards of the relevant (...) domain of cognition, not influenced by irrelevant or external factors. Reasoning and judgement are thus normatively committed to these standards of correctness. A second and related concern is to explore connections between the idea of freedom and Kant’s conception of autonomy and to identify different points at which autonomy plays a role in the argument of Groundwork III. In the final section, I mine the idea of freedom for a set of normative commitments specific to rational agency that play a foundational role in Kant’s moral conception. (shrink)

Intentionalism is the view that the phenomenal character of an experience is wholly determined by its representational content is very attractive. Unfortunately, it is in conflict with some quite robust intuitions about the possibility of phenomenal spectrum inversion without misrepresentation. Faced with such a problem, there are the usual three options: reject intentionalism, discount the intuitions and deny that spectrum inversion without misrepresentation is possible, or find a way to reconcile the two by dissolving the apparent conflict. Sydney Shoemaker's (1994) (...) introduction of appearance properties is a particularly ingenious way of pursuing the third strategy, by maintaining that there is a representational difference between the phenomenally spectrum-inverted subjects.2 In introducing appearance properties, Shoemaker does two things: he identifies a theoretical role for some family of properties to play, and he suggests a family of properties as candidates to play that role. I'll argue that his proposed candidates do not play the role as well as we would like, suggest some new candidates, and argue that they do a better job. (shrink)
