To model the organization of levels' of cortical dynamics, at least some general scheme for hierarchy, functional diversity, and proper intrinsic control must be provided. Rhythmic control forces the system to iterate its state by short trajectories, which makes it much more stable and predictable without discarding the desirable ability of chaotic systems to make rapid phase transitions. Rhythmic control provides a fundamentally different systems dynamics, one not provided by models that allow the emergence of continuous trajectories in the systems (...) state space. (shrink)

Clinical neuroethics and neuroskepticism are recent entrants to the vocabulary of neuroethics. Clinical neuroethics has been used to distinguish problems of clinical relevance arising from developments in brain science from problems arising in neuroscience research proper. Neuroskepticism has been proposed as a counterweight to claims about the value and likely implications of developments in neuroscience. These two emergent streams of thought intersect within the practice of neurology. Neurologists face many traditional problems in bioethics, like end of life care in the (...) persistent vegetative state, determination of capacity in progressive dementia, and requests for assisted suicide in cognition-preserving neurodegenerative disease (like amyotrophic lateral sclerosis). Neurologists also look to be at the forefront of downstream clinical applications of neuroscience, like pharmacological enhancement of mental life. At the same time, the practice of neurology, concerned primarily with the structure, function, and treatment of the nervous system, has historically fostered a kind of skeptical attitude toward its own subject matter. Not all problems that appear primarily neurological are primarily neurological. This disciplinary skepticism is generally clinical in orientation and limited in scope. The rise of interest in clinical neuroethics and in neuroskepticsim generally suggests a possible broader application. The clinical skepticism of neurology provides impetus for thinking about the appropriate role for skepticism in clinical areas of neuroethics. After a brief review of neuroskepticism and clinical neuroethics, a taxonomy of clinical neuroskepticism is offered and reasons why a stronger rather than weaker form of clinical neuroskepticism is currently warranted.

Neurophilosophy is a controversial scientific discipline lacking a broadly accepted definition and especially a well-elaborated methodology. Views about what neurophilosophy entails and how it can combine neuroscience with philosophy, as in their branches and methodologies, diverge widely. This article, first of all, presents a brief insight into the naturalization of philosophy regarding neurophilosophy and three resulting distinguishable forms of how neuroscience and philosophy may or may not be connected in part 1, namely reductive neurophilosophy, the parallelism between neuroscience and philosophy (...) which keeps both disciplines rather strictly separated and lastly, non-reductive neurophilosophy which aims for a bidirectional connection of both disciplines. Part 2 presents a paradigmatic example of how these three forms of neuroscience and philosophy approach the problem of self, mainly concerning its ontological status. This allows me to compare all three neurophilosophical approaches with each other and to highlight the benefits of a non-reductive form of neurophilosophy. I conclude that especially non-reductive neurophilosophy can give full justice to the complementary position of neurophilosophy right at the intersection between neuroscience, philosophy, and psychology.

The debate about the credentials of sociobiology has persisted because scholars have failed to distinguish the varieties of sociobiology and because too little attention has been paid to the details of the arguments that are supposed to support the provocative claims about human social behavior. I seek to remedy both deficiencies. After analysis of the relationships among different kinds of sociobiology and contemporary evolutionary theory, I attempt to show how some of the studies of the behavior of nonhuman animals meet (...) the methodological standards appropriate to evolutionary research. I contend that the efforts of E. O. Wilson, Richard Alexander, Charles Lumsden, and others to generate conclusions about human nature are flawed, both because they apply evolutionary ideas in an unrigorous fashion and because they use dubious assumptions to connect their evolutionary analyses with their conclusions. This contention rests on analyses of many of the major sociobiological proposals about human social behavior, including: differences in sex roles, racial hostility, homosexuality, conflict between parents and adolescent offspring, incest avoidance, the avunculate, alliances in combat, female infanticide, and gene–culture coevolution.Vaulting Ambitionthus seeks to identify what is good in sociobiology, to expose the errors of premature speculations about human nature, and to prepare the way for serious study of the evolution of human social behavior.

The identity of a natural kind can be construed in terms of its causal profile. This conception is more appropriate to science than two alternatives. The identity of a natural kind is not determined by one causal role because one natural kind can have many causal roles and several functions and because some functions are shared by different kinds. Furthermore, the microstructuralist thesis is wrong: The identity of certain natural kinds is not determined by their microstructure. It is true that (...) if A and B have the same microstructural composition then a sample of a chemical substance A is of the same chemical substance as a sample of B. However, the reverse does not hold. It is not the case that if a sample of a chemical substance A is of the same chemical substance as a sample of B then A and B have the same microstructural composition. This is because a macroscopic NK can be “multiconstituted” by different microstructures. (shrink)

In this paper, by analyzing the Chalmers-Searle debate about Chalmers’ zombie thought experiment, I attempt to determine the implications that the irreducibility of consciousness has for the truth of materialism. While Chalmers claims that the irreducibility of consciousness forces us to embrace dualism, Searle claims that it has no deep metaphysical import and, in particular, that it is fully consistent with his materialist theory of mind. I argue that this disagreement hinges on the notion of physical identity in play in (...) the discussion. Clarifying this notion in turn helps to clarify what it means to claim that consciousness is irreducible, and provides insight into the implications that the truth of this claim would have for the dualism-materialism debate. Ultimately, I suggest that the sort of irreducibility that can be motivated by the zombie thought experiment is not sufficient to require the rejection of materialism. (shrink)

Among the newly enchristianed "extreme sports" category, ultrarunners and the sport of ultrarunning is on the fringe edge. What makes ultrarunners and their "sport" interesting is that ultrarunners regularly report experiences that can be equated to various types of mystical experiences during their "sporting" events. This paper briefly discusses ultrarunners, a hypothetical mystical (mythical) state of consciousness called Absolute Unitary Being, and the psychoneurophysiological aspects of ultrarunning. Through this process, a link is established that connects ultrarunners and their "sport" with (...) many traditional indigenous practices. It is suggested that many of the traditional indigenous practices may have produced experiences similar to those of ultrarunners, and thus we can look to ultrarunners to begin to understand some of the physiological, psychological, neurological, as well as humanistic, phenomenological, and transpersonal experiences and reasons behind many now lost traditional indigenous practices.

The work in progress reported by Wright & Liley shows great promise, primarily because of their experimental and simulation paradigms. However, their tentative conclusion that macroscopic neocortex may be considered (approximately) a linear near-equilibrium system is premature and does not correspond to tentative conclusions drawn from other studies of neocortex.

For three decades the writings of Jaegwon Kim have had a major influence in philosophy of mind and in metaphysics. Sixteen of his philosophical papers, together with several new postscripts, are collected in Kim [1993]. The publication of this collection prompts the present essay. After some preliminary remarks in the opening section, in Section 2 I will briefly describe Kim's philosophical 'big picture' about the relation between the mental and the physical. In Section 3 I will situate Kim's approach on (...) the larger philosophical landscape, vis-à-vis various other approaches frequently discussed in contemporary philosophy of mind. This comparative discussion will further illuminate Kim's own position, and also will serve as groundwork for subsequent discussion. In Section 4 I will point out certain persistent internal tensions in Kim's philosophical position on the mind--body problem, tensions that emerge especially clearly against the backdrop of Section 3's comparative discussion of Kim's position relative to various competing positions. In the remainder of the paper I will focus on two issues at the heart of his position, with particular attention to what he says about them in some of the more recent papers and the postscripts in Kim [1993]. First, how should a materialist understand the notion that the mental is 'determined' by the physical? More specifically, what role, if any, should be played by the concept of supervenience in explicating this kind of determination relation? Kim's views on this matter have recently changed, and I will discuss the issue with particular attention to his own latest remarks on it. This is the business of Section 5. Second, need a viable materialism assert that mentalistic psychology is reducible to neurobiology (and ultimately to physics)? More specifically, should a materialist insist on reducibility, despite the currently influential line of argument used by non-reductive materialists, the 'multiple realization' argument? On this matter too, Kim's views have changed somewhat; again, I will discuss the issue with particular attention to his recent thinking. This is the business of Section 6. (shrink)

According to an idea which is widespread among philosophers, linguistic entities derive their intentionality from the intentionality of mental entities by virtue of some relation between them. Typically, it is some kind of intention on the speaker’s part – e.g., an intention to produce in the hearer a belief with a certain content – that is supposed to endow words with content. This paper argues that the concept of the derivation of content from one entity to another, if understood realistically, (...) is flawed: derived intentionality, I will argue, is merely ascribed intentionality, not a real property of its possessor. Irrealistic-ascriptivist senses are suggested for the ideas of content derivation, of original intentionality, and of the mind as the source of linguistic intentionality. Thus, endorsing the idea that mental intentionality is the source of non-mental intentionality need not tempt one to intentional realism. In an intentional irrealistic framework, what forms of intentionality are original and what are derived is a deeply contingent matter, determined by our practice of content ascription. But while intentional irrealism accommodates all those ideas, this paper defends “content-derivation irrealism” but not thoroughgoing intentional irrealism – the idea that there is real original intentionality is not ruled out. Still, assuming that some entities possess real intentionality, what can make them endow intentionality upon other entities is also our practice of content ascription. (shrink)

Most contemporary philosophers of mind claim to be in search of a 'naturalistic' theory. However, when we look more closely, we find that there are a number of different and even conflicting ideas of what would count as a 'naturalization' of the mind. This article attempts to show what various naturalistic philosophies of mind have in common, and also how they differ from one another. Additionally, it explores the differences between naturalistic philosophies of mind and naturalisms found in ethics, epistemology, (...) and philosophy of science. Section 1 introduces a distinction between two types of project that have been styled 'naturalistic', which I call philosophical naturalism and empirical naturalism . Sections 2 to 6 canvass different strands of philosophical naturalism concerning the mind, followed by a much briefer discussion of attempts to provide empirical naturalizations of the mind in Section 7 . Section 8 concludes the essay with a consideration of the relations between philosophical and empirical naturalism in philosophy of mind, arguing that at least some types of philosophical naturalism are incompatible with empirical naturalism.

It has commonly been argued that certain types of mental descriptions, specifically those characterized in terms of propositional attitudes, are part of a folk psychological understanding of the mind. Recently, however, it has also been argued that this is the case even when such descriptions are employed as part of scientific theories in domains like social psychology and comparative psychology. In this paper, I argue that there is no plausible way to understand the distinction between folk and scientific psychology that (...) can support such claims. Moreover, these sorts of claims can have adverse consequences for the neuroscientific study of the brain by downplaying the value of many psychological theories that provide information neuroscientists need in order to build and test neurological models.

Some biologists now argue in favour of a pluralistic approach to plant activities, understandable both from the classical perspective of physiological mechanisms and that of the biology of behaviour involving choices and decisions in relation to the environment. However, some do not hesitate to go further, such as plant “neurobiologists” or philosophers who today defend an intelligence, a mind or even a plant consciousness in a renewed perspective of these terms. To what extent can we then adhere to pluralism in (...) the study of plant behaviour? How does this pluralism in the study and explanation of plant behaviour fit into, or even build itself up, in a broader history of science? Is it a revolutionary way of rethinking plant behaviour in the twenty-first century or is it an epistemological extension of an older attitude? By proposing a synthesis of the question of plant behaviour by selected elements of the history of botany, the objective is to show that the current plant biology is not unified on the question of behaviour, but that its different tendencies are in fact part of a long botanical tradition with contrasting postures. Two axes that are in fact historically linked will serve as a common thread. 1. Are there several ways of understanding or conceiving plant behaviour within plant sciences and their epistemology? 2. Can the behaviour of a plant be considered in the same way as that of an animal? The working hypothesis defended in this article consists in showing that the current opposition between growth, development and reductionist physiology on the one hand and the biology of behaviour involving sensitivity and choices in plant activity on the other hand has been built up through the history of botany.

In this paper, I seek to extract what I call an empiricist mode of existence through a combined reading of two under-researched vectors of Gilles Deleuze's thought: his ‘transcendental empiricism’ and his ‘affirmative naturalism’. This empiricist mode of existence co-positions Deleuze's empiricism and naturalism as pertaining to a stylistics of life which is ontologically experimentalist, epistemologically open, and immanently engaged in the world. That is, a processual praxis of demystification and organising encounters towards joy.

In contemporary human brain mapping, it is commonly assumed that the “mind is what the brain does”. Based on that assumption, task-based imaging studies of the last three decades measured differences in brain activity that are thought to reflect the exercise of human mental capacities (e.g., perception, attention, memory). With the advancement of resting state studies, tractography and graph theory in the last decade, however, it became possible to study human brain connectivity without relying on cognitive tasks or constructs. It (...) therefore is currently an open question whether the assumption that “the mind is what the brain does” is an indispensable working hypothesis in human brain mapping. This paper argues that the hypothesis is, in fact, dispensable. If it is dropped, researchers can “meet the brain on its own terms” by searching for new, more adequate concepts to describe human brain organization. Neuroscientists can establish such concepts by conducting exploratory experiments that do not test particular cognitive hypotheses. The paper provides a systematic account of exploratory neuroscientific research that would allow researchers to form new concepts and formulate general principles of brain connectivity, and to combine connectivity studies with manipulation methods to identify neural entities in the brain. These research strategies would be most fruitful if applied to the mesoscopic scale of neuronal assemblies, since the organizational principles at this scale are currently largely unknown. This could help researchers to link microscopic and macroscopic evidence to provide a more comprehensive understanding of the human brain. The paper concludes by comparing this account of exploratory neuroscientific experiments to recent proposals for large-scale, discovery-based studies of human brain connectivity. (shrink)

There is a strong philosophical intuition that direct study of the brain can and will constrain the development of psychological theory. When this intuition is tested against case studies on the neurophysiology and psychology of perception and memory, it turns out that psychology has led the way toward knowledge of neurophysiology. An abstract argument is developed to show that psychology can and must lead the way in neuroscientific study of mental function. The opposing intuition is based on mainly weak arguments (...) about the fundamentality or objectivity of physics or physiology in relation to psychology. -/- Philosophy of Science, Vol. 67, Supplement.

In this essay, I consider whether it makes sense to say that our cognitive capacities—remembering, imagining, intending, hoping, expecting and so on—manifest as inner, subpersonal processes. Given whether something makes sense is a grammatical rather than theoretical or empirical issue, it cannot be explained but can only be better understood by describing and reflecting on situations in which it arises. As such, I approach this issue using the descriptive method of O.K. Bouwsma, which is a development of Wittgenstein's latter methodological (...) approach of conceptually clarifying our bounds of sense. In the course of my investigation, I come to the realisation that cognitive capacities do not, as much psychology and cognitive science imply, make sense as inner, subpersonal processes. Instead, they make sense as personal capacities, which manifest in many ways of acting. (shrink)

In trying to characterize the relationship between psychology and neuroscience, the trend has been to argue that reductionism does not work without suggesting a suitable substitute. I offer explanatory extension as a good model for elucidating the complex relationship among disciplines which are obviously connected but which do not share pragmatic explanatory features. Explanatory extension rests on the idea that one field can "illuminate" issues that were incompletely treated in another. In this paper, I explain how this "illumination" would work (...) between psychology and neuroscience. (shrink)

Although this is an impressive piece of modeling work, I worry that the two models that Wright & Liley have created do not yet provide us with useful empirical information regarding brain processing.

The neuroscience revolution has led many scientists to posit “expansive” or “thinking” brains that instantiate rich psychological properties. As a result, some scientists now even claim you are identical to such a brain. However, Eric Olson has offered new arguments that thinking brains cannot exist due to their intuitively “abominable” implications. After situating the commitment to thinking brains in the wider scientific discussions in which they are posited, I then critically assess Olson's arguments against such entities. Although highlighting an important (...) insight, I show that Olson's objections to the existence of thinking brains fail and that a wider discussion engaging our new empirical findings is actually required in order to resolve the deeper issues.

The philosophical interest in experimental practice in neuroscience has brought renewed attention to the study of the development and use of techniques and tools for data production. John Bickle has argued that the construction and progression of theories in neuroscience are entirely dependent on the development and ingenious use of research tools. In Bickle's account, theory plays a tertiary role, as it depends on what the tools allow researchers to manipulate, and the tools, in turn, are developed not in order (...) to test theories but as solutions to engineering problems. However, Bickle's account is not entirely precise in explaining what informs researchers' decision-making in their atheoretical laboratory tinkering. Identifying the sources that guide researchers in tool development and use is crucial if one wishes to contribute to the philosophical or meta-scientific understanding of experimental practice in neuroscience. In the following paper, I claim that decision-making in tools' development and use in neuroscience is doubly guided. Pre-existing theory and concepts determine information's relevance, whereas tools' functioning in controlled situations determines information's reliability. Accordingly, experimenters' decision-making is situated both in the context of analysing, modelling or interpreting information and in the context of producing information. I study the case of the tungsten microelectrode developed by David Hubel during the 1950s. First, I show that pre-existing theory and concepts determine in advance what information would be relevant to obtain from the microelectrode. Second, I show that Hubel's tinkering follows the guidelines derived from the very structure of what we recognise as reliable experimentally produced information. Finally, I suggest that data-production processes allow experimenters to assess what to expect from an experimental system in terms of concept- and theory-generation and confirmation, thereby endorsing Bickle's tenet on the tertiary role of theory in neuroscience.

Classical statistical mechanics posits probabilities for various events to occur, and these probabilities seem to be objective chances. This does not seem to sit well with the fact that the theory’s time evolution is deterministic. We argue that the tension between the two is only apparent. We present a theory of Humean objective chance and show that chances thus understood are compatible with underlying determinism and provide an interpretation of the probabilities we find in Boltzmannian statistical mechanics.
