Various theories suggest conscious phenomena are based exclusively on brain activity, while others regard them as a result of the interaction between embodied agents and their environment. In this paper, I will consider whether this divergence entails the acceptance of the fact that different theories can be applied in different scales (as in the case of physics), or if they are reconcilable. I will suggest that investigating how the term representation is used can reveal some hints, building upon which we (...) can bridge the gulf between the two poles in the long run. In my argumentation I will rely on some earlier philosophical insights, such as those of Descartes, James, Wittgenstein and Merleau-Ponty, as well as research based on global workspace theory, and the conceptions of embodied and enacted cognition. I will suggest that within a wider horizon of investigation, the ambiguity as regards the term representation will decrease. (shrink)

It has long been known that brain damage has important negative effects on one’s mental life and even eliminates one’s ability to have certain conscious experiences. It thus stands to reason that when all of one’s brain activity ceases upon death, consciousness is no longer possible and so neither is an afterlife. It seems clear that human consciousness is dependent upon functioning brains. This essay reviews some of the overall neurological evidence from brain damage studies and concludes that our argument (...) from brain damage has been vindicated by such overwhelming evidence. It also puts forth a more mature philosophical rationale against an afterlife and counters several replies to the argument. -/- 1. Philosophical Background -- 2.

The ultimate goal of research into computational intelligence is the construction of a fully embodied and fully autonomous artificial agent. This ultimate artificial agent must not only be able to act, but it must be able to act morally. In order to realize this goal, a number of challenges must be met, and a number of questions must be answered, the upshot being that, in doing so, the form of agency to which we must aim in developing artificial agents comes (...) into focus. This chapter explores these issues, and from its results details a novel approach to meeting the given conditions in a simple architecture of information processing. (shrink)

This article describes three experiments that would advance our understanding of the import of data already generated by scientific work on free will and related issues. All three can be conducted with existing technology. The first concerns how reliable a predictor of behavior a certain segment of type I and type II RPs is. The second focuses on the timing of conscious experiences in Libet-style studies. The third concerns the effectiveness of conscious implementation intentions. The discussion of first two experiments (...) highlights some important problems with certain inferences made on the basis of existing data in scientific work on free will. The discussion of the third calls attention to powerful evidence that conscious intentions sometimes are among the causes of corresponding actions. This evidence has been largely ignored in the literature on free will. (shrink)

Numbers are concepts whose content, structure, and organization are influenced by the material forms used to represent and manipulate them. Indeed, as argued here, it is the inclusion of multiple forms (distributed objects, fingers, single- and two-dimensional forms like pebbles and abaci, and written notations) that is the mechanism of numerical elaboration. Further, variety in employed forms explains at least part of the synchronic and diachronic variability that exists between and within cultural number systems. Material forms also impart characteristics like (...) linearity that may persist in the form of knowledge and behaviors, ultimately yielding numerical concepts that are irreducible to and functionally independent of any particular form. Material devices used to represent and manipulate numbers also interact with language in ways that reinforce or contrast different aspects of numerical cognition. Not only does this interaction potentially explain some of the unique aspects of numerical language, it suggests that the two are complementary but ultimately distinct means of accessing numerical intuitions and insights. The potential inclusion of materiality in contemporary research in numerical cognition is advocated, both for its explanatory power, as well as its influence on psychological, behavioral, and linguistic aspects of numerical cognition.

The mind-body problem concerns the relationship between mind and body, or nowadays - between mind or consciousness and the brain. As a relationship, this can be viewed from two perspectives: from body to mind and from mind to body. In this note I point out that the two readings of the problem are not symmetrical and that there are categorical differences between them. In particular, whereas the body to mind problem constitutes a mystery (cf. the contemporary hard problem), the mind (...) to body problem may be approached from a psychological (as contrasted with philosophical) orientation that allows for concrete phenomenological investigation.

Advances in the neurosciences have many implications for a collective understanding of what it means to be human, in particular, notions of the self, the concept of volition or agency, questions of individual responsibility, and the phenomenology of consciousness. As the ability to peer directly into the brain is scientifically honed, and conscious states can be correlated with patterns of neural processing, an easy—but premature—leap is to postulate a one-way, brain-based determinism. That leap is problematic, however, and emerging findings in (...) neuroscience can even be seen as compatible with some of the basic tenets of existentialism. Given the compelling authority of modern “science,” it is especially important to question how the findings of neuroscience are framed, and how the articulation of research results challenge or change individuals’ perceptions of themselves. Context plays an essential role in the emergence of human identity and in the sculpting of the human brain; for example, even a lack of stimuli (“nothing”) can lead to substantial consequences for brain, behavior, and experience. Conversely, advances in understanding the brain might contribute to more precise definitions of what it means to be human, including definitions of appropriate social and moral behavior. Put another way, the issue is not simply the ethics involved in framing neurotechnology, but also the incorporation of neuroscientific findings into a richer understanding of human ethical (and existential) functioning.

Collectivities (states, club, unions, teams, etc.) are often fruitfully spoken of as though they possessed representational capacities. Despite this fact, many philosophers reject the possibility that collectivities might be thought of as genuinely representational. This paper addresses the most promising objection to the possibility of collective representation, the claim that there is no explanatory value to positing collective representations above and beyond the representational states of the individuals that compose a particular collectivity. I claim that this argument either proves too (...) much, also giving us reason to abandon person-level representations, or it proves too little, demonstrating precisely the sort of continuity between individual and collective representations that would warrant the positing of genuine collective representations. I conclude with a brief sketch of two promising cases of collective representation that lend credence to my claim that individual representations and collective representations are analogous in a way that warrants the study of collective mentality from within the cognitive sciences.

This paper argues for two major revisions in the way philosophers standardly think of vision science and vision theories more generally. The first concerns mental representations and the second supervenience. The central result is that the way is cleared for an externalist theory of perception. The framework for such a theory has what are called Aristotelian representations as elements in processes the well-functioning of which is the principal object of a theory of vision.
