In recent years new findings in vertebrate neuroanatomy have challenged received views on the evolution of the brain. Established theories suggesting that new structures are added to older structures or that old structures are modified into new ones are being re-evaluated. Modification processes, such as invasion and parcellation, have proved to be less valid than originally assumed. Discoveries of neuroanatomical homologies add to the cladistic interpretation problems.

It was not long ago when the consciousness was not considered a problem for science. However, this has now changed and the problem of consciousness is considered the greatest challenge to science. In the last decade, a great number of books and articles have been published in the field, but very few have focused on the how consciousness evolves and develops, and what characterizes the transitions between different conscious states, in animals and humans. This book addresses these questions. Renowned researchers (...) from different fields of science (including neurobiology, evolutionary biology, ethology, cognitive science, computational neuroscience and philosophy) contribute with their results and theories in this book, making it a unique collection of the state-of-the-art of this young field of consciousness studies. - First book on the topic - Focus on different levels of consciousness, including: Evolutionary, developmental, and functional - Highly interdisciplinary.

Report on the Agora Workshop, in Sigtuna, Sweden, on 11-3 August 2001, Agora for Biosystems, P.O. Box 57, SE-193 22 Sigtuna, Sweden.

This article examines three aspects of the problem of understanding Benjamin Libet’s idea of conscious will causally interacting with certain neural activities involved in generating overt bodily movements. The first is to grasp the notion of cause involved, and we suggest a definition. The second is to form an idea of by what neural structure(s) and mechanism(s) a conscious will may control the motor activation. We discuss the possibility that the acts of control have to do with levels of supplementary (...) motor area activity and with the activation of populations of excitatory and inhibitory interneurons. The third aspect is to conceive of the main features of Libet’s proposed conscious mental field (CMF). We consider both an ontological and an epistemological interpretation of the CMF being nonphysical. In an attempt to refute the idea that Libet’s dualist mind–brain interactionism would violate the law of conservation of energy, we suggest that a CMF may alter the probability of the ion-channel gating by influencing structures of a size to which quantum mechanics needs to be applied. We argue that given the suggested definition of cause, and given the epistemological interpretation of the CMF being nonphysical, nothing would necessarily rule out that an element of a CMF, conscious will, may causally interact with neural activities in the brain. This defense of the idea of conscious will being causally efficacious has a bearing not only on the understanding of the mind–brain relation but also on the free will debate. (shrink)

This article compares Wolfgang Köhler's pioneering field theory of the consciousness–brain relation with Benjamin Libet's conscious mental field theory and Karl Popper's mental force field hypothesis. In the discussion of Köhler's theory we devote special attention to his analysis of problems of sense perception and to his explanation of figural after-effects. Both Libet and Popper take consciousness to causally interact with the brain, and we argue that even Köhler presupposes an interactionist interpretation of the consciousness–brain relation. We argue that nothing (...) necessarily rules out that consciousness as something subjective may causally interact with the brain as something objective. We discuss an evolutionary argument for the theory that consciousness causally interacts with the brain, and we consider some arguments for consciousness having had a survival value. (shrink)

The main objective of this essay is to validate some of the principal, currently competing, mammalian consciousness-brain theories by comparing these theories with data on both cognitive abilities and brain organization in birds. Our argument is that, given that multiple complex cognitive functions are correlated with presumed consciousness in mammals, this correlation holds for birds as well. Thus, the neuroanatomical features of the forebrain common to both birds and mammals may be those that are crucial to the generation of both (...) complex cognition and consciousness. The general conclusion is that most of the consciousness-brain theories appear to be valid for the avian brain. Even though some specific homologies are unresolved, most of the critical structures presumed necessary for consciousness in mammalian brains have clear homologues in avian brains. Furthermore, considering the fact that the reptile-bird brain transition shows more structural continuity than the stem amniote-mammalian transition, the line drawn at the origin of mammals for consciousness by several of the theorists seems questionable. An equally important point is that consciousness cannot be ruled out in the absence of complex cognition; it may in fact be the case that consciousness is a necessary prerequisite for complex cognition.

How do we change the normative landscape by making requests? It will be argued that by making requests we create reasons for action if and only if certain conditions are met. We are able to create reasons if and only if doing so is valuable for the requester, and if they respect the requestee. Respectful requests have a normative force – it will be argued – because it is of instrumental value to us that we all have the normative power (...) of creating reasons by making requests. The normative power has the potential for creating and shaping valuable interactions and relationships for the requester and the requestee. This potential could not be realized if we did not have the normative power of making requests. It will also be shown why this account of the normative force of requests should be preferred to the two alternative accounts of the reason-giving force of requests that have been put forward by James H.P. Lewis and David Enoch. (shrink)

Kinship terminologies are basic cognitive semantic systems that all human societies use for organizing kin relations. Diversity in kinship systems and their categories is substantial, but constrained. Rácz, Passmore, and Jordan explore hypotheses about such constraints from learning theories and social pressures, testing the impact of a community‐size driven learning bottleneck against the social coordination demands of different kinds of marriage and resource systems.

Everyone allows that human and animal minds are distinctively (indeed, massively) different in their manifest effects. Humans have been able to colonize nearly every corner of the planet, from the artic, to deserts, to rainforests (and they did so in the absence of modern technological aids); they live together in large cooperative groups of unrelated individuals; they communicate with one another using the open-ended expressive resources of natural language; they are capable of cultural learning that accumulates over generations to result (...) in science, art, and agriculture; and they are remarkably thoughtful and inventive. There is much less agreement about how these manifest differences should be explained, however. (shrink)

Methodological questions concerning Chomsky’s generative approach to linguistics have been debated without consensus. The status of linguistics as psychology, the psychological reality of grammars, the character of tacit knowledge and the role of intuitions as data remain heatedly disputed today. I argue that the recalcitrance of these disputes is symptomatic of deep misunderstandings. I focus attention on Michael Devitt’s recent extended critique of Chomskyan linguistics and I suggest that his complaints are based on a failure to appreciate the special status (...) of Chomsky’s computational formalisms found elsewhere in cognitive science. Devitt ascribes an intentional conception of representations that Chomsky repudiates and that is independently implausible. I argue that Devitt’s proposed “linguistic reality ” as the proper subject matter of linguistics neglects the problems of tokens as opposed to types and he misses the force of Chomsky’s arguments against Behaviourism and nominalism. I suggest that Devitt’s case against intuitions as data misunderstands their standard role throughout perceptual psychology. Finally, of more general interest, I argue that Devitt’s position exemplifies compelling errors concerning mental representation seen throughout cognitive science and philosophy of mind. (shrink)

I explore a strand of reception history that follows Rudolf Carnap’s shift from a purely syntactical analysis of constructed languages to his conception of pure semantics. My exploration focuses on Gustav Bergmann’s and Everett Hall’s interpretation of pure semantics, their understanding of what constitutes a ’formal’ investigation of language, and their arguments concerning the relationship between expressions and their extra-linguistic referents. I argue that Bergmann and Hall strongly misread Carnap’s semantic project and, subsequently, their misunderstanding is passed down through colleagues (...) and students. (shrink)

In this essay, I claim that certain passages in Book IV of Benedict de Spinoza’s Ethics suggest a novel version of what is known as metaethical constructivism. The constructivist interpretation emerges in the course of attempting to resolve a tension between Spinoza’s apparent ethical egoism and some remarks he makes about the efficacy of collaborating with the right partners when attempting to promote our individual self-interest . Though Spinoza maintains that individuals necessarily aim to promote their self-interest, I argue that (...) Spinoza has an atypical conception of self that allows the interests of other people to be partially constitutive of one's own self-interest. In this way, Spinoza can account for the rationality of concern for the interests of others . This interpretation attributes to Spinoza a form of constructivism that differs in important ways from contemporary Humean and Kantian constructivisms and which can in principle be detached from Spinoza’s particular metaphysical commitments in order to yield a third general category of constructivist view . Though my treatment is necessarily brief, it is my hope that it can serve both to motivate a constructivist reading of Spinoza and, perhaps even more crucially, to suggest a Spinozistic variety of constructivism as a live theoretical option in metaethics.

The primary aim of this important study is to produce a reliable account of Peter Martyr’s life before he left Italy in 1542. Earlier biographers had been content to follow the Swiss Calvinist Josiah Simler, who knew Peter Martyr in later years, delivered his funeral oration and published it in 1563. Dr McNair has tried ‘to delve beneath Simler to contemporary records’. He has discovered, for example, that Peter Martyr was born in 1499 not, as is usually (...) said, in 1500. He has been concerned to find out when Peter Martyr left his order and his Church, suggesting that there is little reason to believe that his apostasy began in his years at the University of Padua, 1518-26; it was in Naples, between 1537 and 1540, when he came to know Juan de Valdés, that Peter Martyr’s conversion took place. ‘He arrived a reformer after the order of Ximénez, he left a reformer after the order of Zwingli’, writes Dr McNair, meaning by this the Zwingli of the years immediately before 1523, when he wished to go further than Erasmus but not so far as Luther.

This is the first comprehensive study of the philosophical achievements of twelfth-century Western Europe. It is the collaboration of fifteen scholars whose detailed survey makes accessible the intellectual preoccupations of the period, with all texts cited in English translation throughout. After a discussion of the cultural context of twelfth-century speculation, and some of the main streams of thought - Platonic, Stoic, and Arabic - that quickened it, comes a characterisation of the new problems and perspectives of the period, in scientific (...) inquiry, speculative grammar, and logic. This is followed by a closer examination of the distinctive features of some of the most innovative thinkers of the time, from Anselm and Abelard to the School of Chartres. A final section shows the impact of newly recovered works of Aristotle in the twelfth-century West. (shrink)

This article evaluates the scientific credentials of a distinction that is frequently endorsed by scientists who study human reasoning, between so-called “System 1” and “System 2”. The paper argues that one aspect of what is generally intended by this distinction is real. In particular, there is a real distinction between intuitive and reflective cognitive processes. But this distinction fails to line up with many of the other properties attributed to System 1 and System 2. Accordingly, the paper argues that the (...) latter distinction is not real, and should be abandoned. (shrink)

Suppose that time is infinitely long towards the future, and that each feasible action produces a finite amount of utility at each time. Then, under appropriate conditions, each action produces an infinite amount of utility. Does this mean that utilitarianism lacks the resources to discriminate among such actions? Since each action produces the same infinite amount of utility, it seems that utilitarianism must judge all actions permissible, judge all actions impermissible, or remain completely silent. If the future is infinite, that (...) is, the prospects for utilitarianism look bleak. (shrink)

A major problem with the Christian doctrine of the Incarnation is that Jesus is meant to be both God and man. Richard Swinburne attempts to overcome the problem by having it that in him there are two consciousnesses – the consciousness of being God, and the consciousness of being a man. This position is rejected, on the Aristotelian ground that one consciousness is enough to explain with dignity the mind of Christ.

In the second chapter of his book Kant and the Exact Sciences Michael Friedman deals with two different interpretations of the relation or the difference between algebra and arithmetic in Kant's thought. According to the first interpretation algebra can be described as general arithmetic because it generalizes over all numbers by the use of variables, whereas arithmetic only deals with particular numbers. The alternative suggestion is that algebra is more general than arithmetic because it considers a more general class of (...) magnitudes. This means that arithmetic is concerned only with rational magnitudes, whereas algebra is also concerned with irrational magnitudes. In this article, I will discuss which of the two aforementioned approaches is to be considered the most plausible interpretation of Kant's theory of algebra and arithmetic. According to Friedman, the first interpretation cannot be reconciled with certain statements made by Kant on various occasions. The second interpretation is developed by Friedman himself. It is meant to be an attempt to avoid such inconsistencies. By a detailed analysis of the texts Friedman himself cites I shall examine the soundness of his arguments against the first interpretation and the compatibility of his own interpretation of the difference between algebra and arithmetic with the relevant passages in Kant's texts. It will turn out that the reasons that make Friedman reject the first interpretation are invalid as they are based on misunderstandings and that his own interpretation does not expound Kant's notions on that subject correctly, whereas the first interpretation is compatible with these passages. Thus, I conclude that the interpretation rejected by Friedman, unlike his own approach, is actually the more adequate interpretation of Kant. (shrink)

In this chapter, Amato explores the concept of “vernacular rationality” introduced by Emmanuel Chukwude Eze in his On Reason: Rationality in a World of Cultural Conflict and Racism. Amato interrogates the different ways this idea can be unfolded, expanded, and developed in the spirit if not the letter of Eze’s employment in relation to Hans-Georg Gadamer’s Philosophical Hermeneutics—in particular, its conception of the role tradition plays in the pursuit of understanding and the idea of hermeneutics as practical philosophy. A more (...) hermeneutical conception of vernacular rationality would have the benefit of embracing the linguisticality of our circumstance, and reorienting our rationality toward one another in conversation and dialogue. From the standpoint of Philosophical Hermeneutics this requires us to engage in a critical-constitutive relation toward our tradition(s), emphasizing the work of listening within and between tradition(s), and broadening the circle of listening so as to strengthen the practical connections that allow conversation and dialogue to overcome the irrational and inhumane.

Scheuerman’s book is one of the handful of significant attempts to rethink Schmitt’s work systematically over the past four decades. In so doing, he raises three key questions for me. First, is Schmitt’s work a sincere contribution to legal and political theory, or an attempt to argue for setting the rule of law aside for authoritarianism, that is, an instrumental critique of indeterminacy? Second, to what extent is Schmitt – critical of the ‘bourgeois’ rule of law, critical of globalization – (...) really a thinker defending capitalism? Can he really be associated with the Ordoliberals (even if they adopted his arguments from 1931 to 1932 in their own writing of the time)? Third, to what extent were Schmitt’s early contributions to National Socialist law aimed at responding to legal indeterminacy, and to what extent did they in fact point towards a radicalism of German law within the Nazi system, especially insofar as they endorsed making decisions based on the principles of justice of the Nazi state – and potentially against the express language of statutes?

As argumentation theory has moved away from classical logic as a standard, sources have played an increasingly important role in the psychology of argumentation. Considering the connections between arguments and their sources is important for both descriptive and normative projects. This chapter draws together different strands of research in the psychology of argumentation and their differing views on source characteristics: namely, procedural rules, pragmatics, argumentation schemes and Bayesian Argumentation. We argue for a reconciliation of these different approaches around a probabilistic (...) notion of relevance. (shrink)

Welches ist die Bedeutung des Humanismus für die soziologische Erkenntnisbildung? Seit der Entstehung der Soziologie wurde diese Frage immer wieder aufgeworfen – um bald darauf wieder zu verschwinden. Und damit blieb auch der eigentliche Gegenstand dieser Frage bis heute verborgen: die Bestimmung der Kultur der Soziologie. Denn die soziologische Erkenntnisbildung, das Erstehenlassen der Wirklichkeit des menschlichen Zusammenlebens in Begriffen, ist eine „kulturelle Tätigkeit“. Am gegenwärtigen Zustand der Soziologie zeigt sich dieser Mangel besonders deutlich, droht das Streben nach soziologischer Erkenntnis sich (...) doch im Niemandsland zwischen „multiparadigmatischen“ Verlegenheitslösungen, Hyperrealitäten methodischer und statistischer Codes und technokratischem Dienstleistungswissen buchstäblich zu verlieren. – Vor diesem Hintergrund versammelt der Band grundlegende Untersuchungen des Vehältnisses von Humanismus und Soziologie. Dabei kommen so unterschiedliche Strömungen wie die Kritische Theorie, Rational Choice und der Poststrukturalismus, so unterschiedliche Autoren wie Karl Mannheim, Talcott Parsons, Leo Strauss und Alfred Weber zur Sprache. Auf diese Weise ermöglicht der Band einen neuen Blick auf die Soziologie, insbesondere auf deren geisteswissenschaftliche Dimension. (shrink)
