One's model of skill determines what one expects from neural network modelling and how one proposes to go about enhancing expertise. We view skill acquisition as a progression from acting on the basis of a rough theory of a domain in terms of facts and rules to being able to respond appropriately to the current situation on the basis of neuron connections changed by the results of responses to the relevant aspects of many past situations. Viewing skill acquisition in (...) this ways suggests how one can avoid the problem currently facing AI of how to train a network to make human-like generalizations. In training a network one must progress, as the human learner does, from rules and facts to wholistic responses. As to future work, from our perspective one should not try to enhance expertise as in traditional AI by attempting to construct improved theories of a domain, but rather by improving the learner's access to the relevant aspects of a domain so as to facilitate learning from experience.

ObjectiveTo demonstrate that the human brain, as a connectionist system, has the capacity to become a free, rational, moral, agent—that is, the capacity to become a self—and that the brain becomes a self by engaging second-order reflection in the hermeneutical task of constructing narratives that rationalise action. StructureSection 2 explains the connectionist brain and its relevant capacities: to categorise, to develop goal-directed dispositions, to problem-solve what it should do, and to second-order reflect. Section 3 argues that the connectionist brain (...) constitutes a self by constructing rational narratives. Section 4 replies to the objection that the connectionist self cannot be free. Conclusion Treating the brain as a connectionist system provides a way to explain the free rational agency of the “connectionist” self. (shrink)

Through a discussion of the socially extended mind, this paper advances the “not possible without principle” as an alternative to the social parity principle. By charging the social parity principle with reductionism about the social dimension of socially extended processes, the paper offers a new argumentative strategy for the socially extended mind that stresses its existential significance. The “not possible without principle” shows that not only is something _more_ achieved through socially located processes of knowledge building, but also that, and (...) more importantly, what is achieved is something that _would not have been possible without_ social interaction_._ The social parity principle states that the result of an activity achieved via social interaction should be assumed functionally equivalent to a solitary investigation and is characterized by multiple realisability. Contrary to the social parity principle, the “not possible without principle” holds that the result would not have been achieved without the social interaction between (at least) two agents with specific existential needs. The socially extended mind never happens in a void. This means that the "not possible without" principle should be located in real-life, affectively charged, embodied experiences of skilful interactions between agents. This fundamental conceptual change via reference to the “existential necessity” that regulates socially extended processes is necessary in order to effectively lead the socially extended mind to a truly embedded and embodied account.

Our culture is dominated by digital documents in ways that are easy to overlook. These documents have changed our worldviews about science and have raised our expectations of them as tools for knowledge justification. This article explores the complexities surrounding the digital document by revisiting Michael Polanyi’s theory of tacit knowledge—the idea that “we can know more than we can tell.” The theory presents to us a dilemma: if we can know more than we can tell, then this means that (...) the communication of science via the document as a primary form of telling will always be incomplete. This dilemma presents significant challenges to the open science movement. (shrink)

Dispositionalism is the view that the world is, ultimately, just a world of objects and their irreducible dispositions, and that such dispositions are, ultimately, the sole explanatory ground for the occurrence of events. This view is motivated, partly, by arguing that it affords, while non‐necessitarian views of laws of nature do not afford, an adequate account of our intuitions about which regularities are non‐accidental. I, however, argue that dispositionalism cannot adequately account for our intuitions about which regularities are non‐accidental. (...) Further, I argue that, intuitions aside, if we suppose that our world contains objects along with their irreducible dispositions, we must suppose, on pain of logical incoherence, that it contains laws of nature that are incompatible with a dispositionalist ontology. Indeed, if we suppose a world of objects and irreducible dispositions, we will have to suppose that the most prominent views of laws of nature currently on offer are all inadequate. (shrink)

In the first section of the article, we examine some recent criticisms of the connectionist enterprise: first, that connectionist models are fundamentally behaviorist in nature (and, therefore, non-cognitive), and second that connectionist models are fundamentally associationist in nature (and, therefore, cognitively weak). We argue that, for a limited class of connectionist models (feed-forward, pattern-associator models), the first criticism is unavoidable. With respect to the second criticism, we propose that connectionist modelsare fundamentally associationist but that this is appropriate for building models (...) of human cognition. However, we do accept the point that there are cognitive capacities for which any purely associative model cannot provide a satisfactory account. The implication that we draw from is this is not that associationist models and mechanisms should be scrapped, but rather that they should be enhanced.In the next section of the article, we identify a set of connectionist approaches which are characterized by “active symbols” — recurrent circuits which are the basis of knowledge representation. We claim that such approaches avoid criticisms of behaviorism and are, in principle, capable of supporting full cognition. In the final section of the article, we speculate at some length about what we believe would be the characteristics of a fully realized active symbol system. This includes both potential problems and possible solutions (for example, mechanisms needed to control activity in a complex recurrent network) as well as the promise of such systems (in particular, the emergence of knowledge structures which would constitute genuine internal models).

Jonna Vance and Preston Werner argue that humans’ mechanisms of perceptual attention tend to be sensitive to morally relevant properties. They dub this tendency “Attentional Moral Perception” (AMP) and argue that it can play all the explanatory roles that some theorists have hoped moral perception can play. In this article, I argue that, although AMP can indeed play some important explanatory roles, there are certain crucial things that AMP cannot do. Firstly, many theorists appeal to moral perception to explain (...) how moral knowledge is possible. I argue that AMP cannot put an agent in a position to acquire moral knowledge unless it is supplemented with some other capacity for becoming aware of moral properties. Secondly, theorists appeal to moral perception to explain “moral conversions”, i.e., cases in which an experience leads an agent to form a moral belief that conflicts with her pre-existing moral beliefs. I argue that AMP cannot explain this either. Due to these shortcomings, theorists should turn to emotions for a powerful and psychologically realistic account of virtuous agents’ sensitivity to the moral landscape. (shrink)

We sometimes stop to reflect on our mental states, and such reflection can lead, at times, to changing our minds. It can, as well, lead us to endorse the very attitudes which we previously held. Such reflective endorsement has been called upon to play a wide range of roles in philosophical theorizing. It has been thought to ground a distinction between two fundamentally different kinds of knowledge: reflective knowledge and mere animal knowledge. It has been thought to serve as a (...) ground for rational change of belief. It has been called upon to explain the possibility of freedom of the will. And it has been brought into service to explain the source of normativity. This chapter argues that it can play none of these roles. (shrink)

Time travel, it has been argued, leads to paradoxes, and in particular to a problem known as the grandfather paradox. Lewis has famously argued for the now standard view that the grandfather paradox is merely apparent. But underlying Lewis's solution is a faulty account of ability statements – one, according to which ability statements express possibility statements. I argue, contrary to Vihvelin and others, that an ameliorated view of ability statements allows for the same treatment of the seeming paradox. Hence, (...) Lewis's take on the grandfather paradox stands despite the failure of the particular view of ability statements it is built upon. (shrink)

In ?155 of his New Theory of Vision Berkeley explains that a hypothetical ?unbodied spirit? ?cannot comprehend the manner wherein geometers describe a right line or circle?.1The reason for this, Berkeley continues, is that ?the rule and compass with their use being things of which it is impossible he should have any notion.? This reference to geometrical tools has led virtually all commentators to conclude that at least one reason why the unbodied spirit cannot have knowledge of plane (...) geometry is because it cannot manipulate a ruler or a compass. In this article I will show that such an interpretation is flawed. I will instead argue that Berkeley's understanding of Euclidian geometry was based on Isaac Barrow's account of the foundations of geometry. On this view geometrical objects are conceived in terms of the idealized motion that generates the objects of geometry. Consequently, that what the unbodied spirit cannot do in this context is to form an idea of motion rather than being unable to handle geometrical tools. 1All references to Berkeley are from, A. A.

Recent metaphysics of science has been fuelled significantly by an interest in causal powers or dispositions. A number of authors have made realism about dispositions central to their projects in the epistemology of science, suggesting that the existence of irreducible powers is a commitment entailed by taking scientific practice seriously. This paper strikes a cautionary note with respect to the two most common arguments for this view, concerning the putative requirement of dispositional properties in the contexts of scientific explanation and (...) scientific abstraction. I contend that neither argument is successful, but that nevertheless, realism about powers better accords with an arguably scientific consideration of property identity, thus affirming the importance of dispositions to the epistemology of science.

It has been claimed that there are certain acts that nurses as people practising nursing must never do because they are nurses and this is regardless of what the same agent should do; that certain actions are not part of proper nursing practice. The concept of an internal morality has been discussed in relation to medicine and has been used to ground the actions proper to medicine in a realist tradition. Although the concept of an internal morality of nursing (...) is not explicitly mentioned in the literature the underpinning ideas about the proper practice of nursing based on philosophical realism I argue equate with it and a discussion of the method of an internal morality can help to understand how arguments against euthanasia related to the profession of nursing are far from clear. Ultimately, although the idea of particular acts proper to nurses qua nurses is not clear, the concept of an internal morality can help to get practitioners to see how the profession is tightly linked to moral actions, even so the hard problems in bioethics such as the morality of euthanasia remain hard for all and the easy ones easy for all.

Despite a growing awareness within American biomedicine and bioethics that the social category “race” is of limited use in describing patients, some fields of medicine continue to use it interchangeably with, or instead of, the term “ethnicity.” Doing so reflects the assumption that social categories have a basis in physiology.

Bioethical work on solidarity has yielded an array of divergent conceptions. But what do these accounts add to normative bioethics? What is solidarity’s distinctive social normative role? Prainsack and Buyx suggest that solidarity be understood as the ‘putty’ of justice. I argue here that the putty metaphor is deeply insightful and—when spelled out in detail—successfully explicates solidarity’s social normative function. Unfortunately, Prainsack and Buyx’s own account cannot play this role. I propose instead that the putty metaphor supports (...) a conception of solidarity as equity. This proposal enables us to answer whether and when we should act in solidarity, and with whom, while also capturing the putty metaphor and hence answering a basic question: what is solidarity for?

According to many orthodox Christian theologies Jesus is not merely sinless but impeccable: he not only did not sin but could not. This is puzzling because one can only sin by doing something else and, prima face, Jesus can do actions that you or I could do by which we would sin. I suggest that appearances to the contrary, Jesus cannot do a variety of actions that a merely human duplicate could do. His doing sinful actions is compossible with (...) a range of empirical facts about his physical abilities and circumstances of the sort we ordinarily take into account in assessing what a person can do, but not with a wider range of theological facts concerning his divinity. Like Tim, Lewis’s time-traveler, who can kill Grandfather relative to facts about his immediate circumstances and abilities but not relative to a wider range of facts, Jesus ‘can’ in the ordinary sense sin, though he will not, but relative to a wider range of facts which obtain in virtue of his divinity, cannot.

I argue against the view that an agent’s knowledge of her own current action cannot in any way rely on perception for its justification. Instead, I argue that when it comes to an agent’s knowledge of her own object-oriented intentional action, the agent’s belief about what she is doing is partly justified by her perception of the object of action. I proceed by first proposing an account of such actions according to which the agent’s knowledge is partly justified (...) by her perception. I then discuss several of objections to my proposal. The most important objection is that I have only managed to show that perception plays an enabling role and not a justificatory role for the agent’s knowledge of her own intentional action. (shrink)

The eliminative view of gauge degrees of freedom—the view that they arise solely from descriptive redundancy and are therefore eliminable from the theory—is a lively topic of debate in the philosophy of physics. Recent work attempts to leverage properties of the QCD $$\theta _{\text {YM}}$$ θ YM -term to provide a novel argument against the eliminative view. The argument is based on the claim that the QCD $$\theta _{\text {YM}}$$ θ YM -term changes under “large” gauge transformations. Here we review (...) geometrical propositions about fiber bundles that unequivocally falsify these claims: the $$\theta _{\text {YM}}$$ θ YM -term encodes topological features of the fiber bundle used to represent gauge degrees of freedom, but it is fully gauge-invariant. Nonetheless, within the essentially classical viewpoint pursued here, the physical role of the $$\theta _{\text {YM}}$$ θ YM -term shows the physical importance of bundle topology (or superpositions thereof) and thus counts against (a naive) eliminativism.

In their article “Roemer's ‘General’ Theory of Exploitation is a Special Case: The Limits of Walrasian Marxism,” Devine and Dymski portray me as some sort of Walrasian automaton who believes that phenomena that are not easily modelled using the Walrasian model of perfect competition do not exist. Their criticism of my theory assumes that I was attempting to model capitalism in its entirety, a task that, I agree, I failed to do. I did not propose a theory of accumulation, or (...) of technological change, or of the methods by which capitalists maintain their ideological hegemony over workers, or of the methods by which they extract labor from labor power at the point of production. I was not, in short, trying to write an alternative to Das Kapital. My General Theory of Exploitation and Class, as its Introduction explained, was an attempt at understanding the root causes of exploitation and class, so as to better understand how class formation and exploitation might occur in postcapitalist societies. To this end, I adopted a well-known scientific method: strip away many real aspects of the thing under study down to a minimal skeleton and see how many phenomena descriptive of the real thing one can generate. Then add more real aspects of the thing to the model, and see how much more one can generate. (shrink)

Many of the good things which make human life worthwhile are essentially social, cannot be enjoyed by one person unless they are enjoyed together with others. And it is obvious that thinking in terms of the first-person plural, we/us, plays a large part in everyday life as people consider puzzlements (‘What should we do?’) and remark on the success of what they decided on (‘That worked out really well for us!’). Analytic philosophers should accept this at face (...) value, recognising that human beings are often co-subjects with each other, that there is irreducible plural intentionality. The paper explores how the existence of plural intentionality manifests itself in our concepts and ways of proceeding and how attempted ‘analysis’ of what goes on as the assemblage of many interlocking instances of singular intentionality distorts and misleads.

Many defenders of the possibility of time travel into the past also hold that such time travel places no restrictions on what said time travelers can do. Some hold that it places at least a few restrictions on what time travelers can do. In attempting to resolve this dispute, I reached a contrary conclusion.

Using a very weak notion of can, I shall (...) argue that the correspondingly strong cannot do otherwise applies in the case of backwards time travel. I defend this result from objections. (shrink)

One natural way to argue for the existence of some subjective constraint on agents’ obligations is to maintain that without that particular constraint, agents will sometimes be obligated to do that which they lack the ability to do. In this paper, I maintain that while such a strategy appears promising, it is fraught with pitfalls. Specifically, I argue that because the truth of an ability ascription depends on an (almost always implicit) characterization of the relevant possibility space, different metaethical accounts (...) take obligation to be constrained by different senses of ability. As a result, what initially looks to be a point of consensus—that ability constrains obligation—turns out to be a point of contention, and arguments with this at the foundation are much more likely to obscure, rather than resolve, metaethical disputes. Despite this, appeals to ability in metaethics aren’t doomed to be fruitless. On the contrary, if we can independently establish a particular sense of ability as the normatively relevant one, then we have good grounds for ruling out metaethical accounts that are inconsistent with it. In the final section, I make just such an argument. What seems right about the thought that ability constrains obligation is that an agent cannot be obligated to do that which her circumstances prevent her from doing. I argue that only a sense of ability that is both epistemically and motivationally restricted adequately respects the limits of agential control. (shrink)

Parfit's requirements for an ideal Theory X cannot be fully met since the Mere Addition Principle and Non-Antiegalitarianism imply the Repugnant Conclusion: Theory X does not exist. However, since the Repugnant Conclusion is really compelling, the Impersonal Total Principle should be adopted for impartial comparisons concerning future generations. Nevertheless, where our own interests are affected, we may yet choose to be partial, trading off our concern for future goodness with our self-interests. Theory X' meets all Parfit's requirements except the (...) Mere Addition Principle in less compelling cases. (shrink)

The Principle of Alternative Possibilities is the intuitive idea that someone is morally responsible for an action only if she could have done otherwise. Harry Frankfurt has famously presented putative counterexamples to this intuitive principle. In this paper, I formulate a simple version of the Principle of Alternative Possibilities that invokes a course-grained notion of actions. After warming up with a Frankfurt-Style Counterexample to this principle, I introduce a new kind of counterexample based on the possibility of time travel. At (...) the end of the paper, I formulate a more sophisticated version of the Principle of Alternative Possibilities that invokes a certain fine grained notion of actions. I then explain how this new kind of counterexample can be augmented to show that even the more sophisticated principle is false. (shrink)

A theory of the evolution of mind cannot be complete without an explanation of how cognition became representational. Artificial approximations of cognitive evolution do not, in general, produce representational cognition. We take this as an indication that there is a gap in our understanding of what drives evolution towards representational solutions, and propose a theory to fill this gap. We suggest selection for learning and selection for second order learning as the causal factors driving the emergence of innate (...) and acquired forms of representation, respectively. Cognition is commonly viewed as a “black box”—selection works on externally visible behaviour alone, with little regard for implementation structure. Yet even if implementation structure is not constrained by selection on behaviour, implementation structure does affect how easy or difficult it is to make specific modifications to the behaviour. Hence selection for learning can affect the implementation structure of behaviour. Similarly, the implementation structure of learning ability itself is not under direct selection, but selection for second order learning can affect the implementation structure of first order learning. We argue that these indirect selection effects guide evolution towards representational implementations, as structural alignment between implementation structure and environment structure guarantees that simple changes in the environment can be met with simple changes in implementation. We illustrate the theory with examples of computational investigations, and discuss how the theory may help put representational cognition within reach of purely connectionist AI. (shrink)

Economists and biologists have proposed a distinction between two mechanisms – “strong” and “weak” reciprocity – that may explain the evolution of human sociality. Weak reciprocity theorists emphasize the benefits of long-term cooperation and the use of low-cost strategies to deter free-riders. Strong reciprocity theorists, in contrast, claim that cooperation in social dilemma games can be sustained by costly punishment mechanisms, even in one-shot and finitely repeated games. To support this claim, they have generated a large body of evidence concerning (...) the willingness of experimental subjects to punish uncooperative free-riders at a cost to themselves. In this article, I distinguish between a “narrow” and a “wide” reading of the experimental evidence. Under the narrow reading, punishment experiments are just useful devices to measure psychological propensities in controlled laboratory conditions. Under the wide reading, they replicate a mechanism that supports cooperation also in “real-world” situations outside the laboratory. I argue that the wide interpretation must be tested using a combination of laboratory data and evidence about cooperation “in the wild.” In spite of some often-repeated claims, there is no evidence that cooperation in the small egalitarian societies studied by anthropologists is enforced by means of costly punishment. Moreover, studies by economic and social historians show that social dilemmas in the wild are typically solved by institutions that coordinate punishment, reduce its cost, and extend the horizon of cooperation. The lack of field evidence for costly punishment suggests important constraints about what forms of cooperation can or cannot be sustained by means of decentralised policing. (shrink)

Resumo: O corpo está por toda parte: ele é aquele que «está irreparavelmente aqui» onde estou, eu que não «posso me deslocar sem ele», já disse o filósofo. Talvez por isso mesmo seja tão antigo e tão insistente o movimento que, multiplicando as metáforas para dizer sua presença, visa de fato a maior parte do tempo seu ocultamento. Assim, se é possível falar aqui de uma cartografia, ela sem dúvida designará o intenso movimento filosófico de ocultamento do corpo, que paradoxalmente (...) dá a ver o que tanto se buscou evitar: é que o corpo sempre resiste, insistindo em se fazer disponível aos «mundos múltiplos e divergentes» que a cada vez a arte aproxima. Palavras-chave: Corpo. Movimento. Formação humana. Cartography of the body and unmanageability: The body is everywhere: he is «is irreparably here» where I am, for «I cannot move without him», as the philosopher said. Perhaps it is why this ancient and persistent movement that multiplies the metaphors to tell its presence seeks in fact its concealment most of the time. Thus, if it is possible to speak about a cartography, it will undoubtedly designate the intense philosophical movement of body concealment, which paradoxically hints at what it has sought so much to avoid: is that the body always resists, insisting on making itself available to « multiple and divergent worlds» which art approaches each time.

This paper argues that neurolinguistics has the potential to yield insights that can feed back into corpus-based Cognitive Linguistics. It starts by discussing how far the cognitive realism of probabilistic statements derived from corpus data currently goes. Against this background, it argues that the cognitive realism of usage-based models could be further enhanced through deeper engagement with neurolinguistics, but also highlights a number of common misconceptions about what neurolinguistics can and cannot do for linguistic theorizing.
