ABSTRACT: Qualia, the subjectively known qualities of conscious experience, are judged by many philosophers and scientists to lie beyond the domain of scientific explanation, thus making the conscious mind partly incomprehensible to the objective physical sciences. Some, like Kripke and Chalmers, employ modal logic to argue that explanations of qualia are impossible in principle. I argue that there already exist perfectly normal scientific explanations of qualia, and rebut the arguments of those who deny this possibility.

Abstract: The notion that philosophy can be practised as a kind of therapy has become a focus of debate. This article explores how philosophy can be practised literally as a kind of therapy, in two very different ways: as philosophical therapy that addresses “real-life problems” (e.g., Sextus Empiricus) and as therapeutic philosophy that meets a need for therapy which arises in and from philosophical reflection (e.g., Wittgenstein). With the help of concepts adapted from cognitive and clinical psychology, and from cognitive (...) linguistics, the article shows that both philosophical projects address important and literally therapeutic tasks and explains how they can do so with genuinely philosophical argument and analysis. This brings into view new applications for philosophy, a need for therapy in core areas of the subject, and the outline of a new approach to meet what will be shown to be a central need. (shrink)

The paper develops and addresses a major challenge for therapeutic conceptions of philosophy of the sort increasingly attributed to Wittgenstein. To be substantive and relevant, such conceptions have to identify “diseases of the understanding” from which philosophers suffer, and to explain why these “diseases” need to be cured in order to resolve or overcome important philosophical problems. The paper addresses this challenge in three steps: With the help of findings and concepts from cognitive linguistics and cognitive psychology, it redevelops the (...) Wittgensteinian notion of “philosophical pictures.” Through a case study on seminal versions of familiar mind-body problems, it examines how such pictures shape philosophical reflection and generate ill-motivated but captivating problems. Third, it shows that philosophical pictures are constitutive of “diseases of the understanding,” in a quite strict sense of the term. On this basis, the paper explains when and why philosophical therapy is required. (shrink)

While life in general can be explained by the mechanisms of physics, chemistry and biology, to many scientists and philosophers it appears that when it comes to explaining consciousness, there is what the philosopher Joseph Levine called an “explanatory gap” between the physical brain and subjective experiences. Here we deduce the living and neural features behind primary consciousness within a naturalistic biological framework, identify which animal taxa have these features (the vertebrates, arthropods, and cephalopod molluscs), then reconstruct when consciousness first (...) evolved and consider its adaptive value. We theorize that consciousness is based on all the complex system features of life, plus the even more complex features of elaborate brains. We argue that the main reason why the explanatory gap between the brain and experience has been so refractory to scientific explanation is that it arises from both life and from varied and diverse brains and brain regions, so bridging the gap requires a complex, multifactorial account that includes the great diversity of consciousness, its personal nature that stems from embodied life, and the special neural features that make consciousness unique in nature.

Our ethical obligations to another being depend at least in part on that being’s capacity for a mental life. Our usual approach to inferring the mental state of another is to reason by analogy: If another being behaves as I do in a circumstance that engenders a certain mental state in me, I conclude that it has engendered the same mental state in him or her. Unfortunately, as philosophers have long noted, this analogy is fallible because behavior and mental states (...) are only contingently related. If the other person is acting, for example, we could draw the wrong conclusion about his or her mental state. In this article I consider another type of analogy that can be drawn between oneself and another to infer the mental state of the other, substituting brain activity for behavior. According to most current views of the mind–body problem, mental states and brain states are non-contingently related, and hence inferences drawn with the new analogy are not susceptible to the alternative interpretations that plague the behavioral analogy. The implications of this approach are explored in two cases for which behavior is particularly unhelpful as a guide to mental status: severely brain–damaged patients who are incapable of intentional communicative behavior, and nonhuman animals whose behavioral repertoires are different from ours and who lack language.

Creativity has a special role in enabling humans to develop beyond the fulfilment of simple primary functions. This factor is significant for Artificial Intelligence (AI) developers who take replication to be the primary goal, since moves toward creating autonomous artificial-beings beg questions about their potential for creativity. Using Wittgenstein’s remarks on rule-following and language-games, I argue that although some AI programs appear creative, to call these programmed acts creative in our terms is to misunderstand the use of this word in (...) language. I conclude that replication is not the best way forward for AI development in matters of creativity. (shrink)

The commentary argues that we cannot be sure that human consciousness has survival value and that in order to understand the origins and, perhaps, the function of consciousness, we should examine the behavioural and neural precursors to consciousness in nonhumans. An example is given of research on the role of context in decisions regarding fleeing from probable predators in the Mongolian gerbil.

Gödel's Theorem is often used in arguments against machine intelligence, suggesting humans are not bound by the rules of any formal system. However, Gödelian arguments can be used to support AI, provided we extend our notion of computation to include devices incorporating random number generators. A complete description scheme can be given for integer functions, by which nonalgorithmic functions are shown to be partly random. Not being restricted to algorithms can be accounted for by the availability of an arbitrary random (...) function. Humans, then, might not be rule-bound, but Gödelian arguments also suggest how the relevant sort of nonalgorithmicity may be trivially made available to machines. (shrink)

It is widely assumed that perception is a source of reasons (SR). There is a weak sense in which this claim is trivially true: even if one characterizes perception in purely causal terms, perceptual beliefs originate from the mind's interaction with the world. When philosophers argue for (SR), however, they have a stronger view in mind: they claim that perception provides pre- or non-doxastic reasons for belief. In this article I examine some ways of developing this view and criticize them. (...) I exploit these results to formulate a series of constraints that a satisfactory account of the epistemic role of perception should fulfil. I also make a positive suggestion: coherentists are right when they claim that only beliefs can be reasons for other beliefs. Nevertheless, I depart from traditional coherentism, for I do not buy its conception of perception as bare sensation, nor explicate the justificatory status of beliefs in terms of coherence. My point is rather that, when one invokes experience to justify a belief, the justifying state must have structural features of beliefs. (shrink)

The comment addresses central issues of a "theory theory" approach as exemplified in Gopnik' and Goldman's BBS-articles. Gopnik, on the one hand, tries to demonstrate that empirical evidence from developmental psychology supports the view of a "theory theory" in which common sense beliefs are constructed to explain ourselves and others. Focusing the informational processing routes possibly involved we would like to argue that his main thesis (e.g. idea of intentionality as a cognitive construct) lacks support at least for two reasons: (...) one methodological and one structural. On the other hand, Goldman raises an important question when he is asking how people ascribe mental states to themselves. Reasons why Goldman's attempt to understand common sense mental representations by using an analogy from visual perception is problematic are discussed. The role which is attributed to a phenomenology is evaluated. (shrink)

The aim of the paper is to present the historical context and the motivation of an investigation still in progress, together with a sketch of some of its results. It starts with a brief description of the nature and history of cognitive science. The relation of cognitive science to logic is then considered, from which consideration a conception of logic as a descriptive and mentalist discipline emerges. Such conception clashes with Frege's antipsychologism. The purpose of the investigation is to refute (...) Frege's arguments, considered as objections to the view that there are two logics, both mentalist, one descriptive and one normative.O objetivo do trabalho é apresentar o contexto histórico, as motivações e um esboço de alguns resultados de uma pesquisa ainda não concluída. Primeiro fala-se um pouco da Ciência Cognitiva - de suas características gerais, de sua história, de sua relação com a Epistemologia. Considera-se depois sua relação com a Lógica, emergindo daí uma concepção da Lógica como descritiva e mentalista. Esta concepção choca-se com o antipsicologismo de Frege. A meta da pesquisa é refutar os argumentos de Frege enquanto objeções à tese de que existem duas lógicas, ambas mentalistas, uma descritiva e outra normativa. (shrink)

The intentional stance is the strategy of prediction and explanation that attributes beliefs, desires, and other states to systems and predicts future behavior from what it would be rational for an agent to do, given those beliefs and desires. Any system whose performance can be thus predicted and explained is an intentional system, whatever its innards. The strategy of treating parts of the world as intentional systems is the foundation of but is also exploited in artificial intelligence and cognitive science (...) more generally, as well as in evolutionary theory. An analysis of the role of the intentional stance and its presuppositions supports a naturalistic theory of mental states and events, their content or intentionality, and the relation between levels of explanation and neurophysiological or mechanistic levels of explanation. As such, the analysis of the intentional stance grounds a theory of the mind and its relation to the body. (shrink)

This commentary is divided into two parts. The first considers a possible role for Gray's predictor plus comparator mechanism in human episodic recognition memory. It draws on the computational specifications of recognition outlined in Humphreys et al. to demonstrate how the logically necessary components of recognition tasks might be mapped onto the mechanism. The second part demonstrates how the mechanism outlined by Gray might be implicated in a form of imitative learning suitable for the acquisition of complex tasks.
