We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical amplification (...) enables conscious perceptual experience and makes it more flexible, and thus more adaptive, by being sensitive to context. Apical amplification provides a possible mechanism for recurrent processing theory that avoids strong loops. It makes the broadcasting hypothesized by global neuronal workspace theories feasible while preserving the distinct contributions of the individual cells receiving the broadcast. It also provides mechanisms that contribute to the holistic aspects of integrated information theory. As apical amplification is highly dependent on cholinergic, aminergic, and other neuromodulators, it relates the specific contents of conscious experience to global mental states and to fluctuations in arousal when awake. We conclude that apical dendrites provide a cellular mechanism for the context-sensitive selective amplification that is a cardinal prerequisite of conscious perception. (shrink)

We argue that prediction success maximization is a basic objective of cognition and cortex, that it is compatible with but distinct from prediction error minimization, that neither objective requires subtractive coding, that there is clear neurobiological evidence for the amplification of predicted signals, and that we are unconvinced by evidence proposed in support of subtractive coding. We outline recent discoveries showing that pyramidal cells on which our cognitive capabilities depend usually transmit information about input to their basal dendrites and amplify (...) that transmission when input to their distal apical dendrites provides a context that agrees with the feedforward basal input in that both are depolarizing, i.e., both are excitatory rather than inhibitory. Though these intracellular discoveries require a level of technical expertise that is beyond the current abilities of most neuroscience labs, they are not controversial and acclaimed as groundbreaking. We note that this cellular cooperative context-sensitivity greatly enhances the cognitive capabilities of the mammalian neocortex, and that much remains to be discovered concerning its evolution, development, and pathology.

Elective abortion has become an issue of ethical and political debate in many countries including Mexico. As gynecologists are directly involved in the practice of abortion, it is important to know the psychological meaning that the term ‘elective abortion’ has for them. This study explores the psychological meaning and attitudes toward elective abortion of one hundred and twenty-three Mexican gynecologists. We used the semantic networks technique, which analyzed the words the participants associated with the term ‘elective abortion’. The defining words (...) most frequently used by participants implied a negative sanction. There were important differences by gender and religiosity: male gynecologists, as well as those with strong religious beliefs (mainly Catholics), revealed a more negative psychological meaning and more negative attitudes than females or physicians with weak religious beliefs. A contribution of the present study is that it highlights the importance of psychology to enhancing understanding of the issue of elective abortion. (shrink)

Euthanasia has become the subject of ethical and political debate in many countries including Mexico. Since many physicians are deeply concerned about euthanasia, due to their crucial participation in its decision and implementation, it is important to know the psychological meaning that the term ‘euthanasia’ has for them, as well as their attitudes toward this practice. This study explores psychological meaning and attitudes toward euthanasia in 546 Mexican subjects, either medical students or physicians, who were divided into three groups: a) (...) beginning students, b) advanced students, and c) physicians. We used the semantic networks technique, which analyzed the words the participants associated with the term ‘euthanasia’. Positive psychological meaning, as well as positive attitudes, prevailed among advanced students and physicians when defining euthanasia, whereas both positive and negative psychological meaning together with more ambivalent attitudes toward euthanasia predominated in beginning students. The findings are discussed in the context of a current debate on a bill proposing active euthanasia in Mexico City. (shrink)

This paper is an attempt to develop the many-valued first-order fuzzy logic. The set of its truth, values is supposed to be either a finite chain or the interval 0, 1 of reals. These are special cases of a residuated lattice L, , , , , 1, 0. It has been previously proved that the fuzzy propositional logic based on the same sets of truth values is semantically complete. In this paper the syntax and semantics of the first-order fuzzy logic (...) is developed. Except for the basic connectives and quantifiers, its language may contain also additional n-ary connectives and quantifiers. Many propositions analogous to those in the classical logic are proved. The notion of the fuzzy theory in the first-order fuzzy logic is introduced and its canonical model is constructed. Finally, the extensions of Gödel's completeness theorems are proved which confirm that the first-order fuzzy logic is also semantically complete. (shrink)

Under one of the last remaining single-party communist regimes, Vietnam’s in-progress transition is a hybrid between post-Soviet reforms and Chinese authoritarian compromise. This chapter provides a brief account of the historical events and cultural attributes that have shaped the current political and economic configuration of the country, a coverage of globalization and entrepreneurial endeavours in relation to trade liberalization, an analysis of growing consumerist tendencies and the solidification of a circle of economic elites, an overview of Vietnamese foreign trade, with (...) a focus on the Association of Southeast Asian Nations (ASEAN) and China as significant partners, and a macroeconomic assessment of the country.

Immanuel Kant was one of the most significant philosophers of the modern age. Historical Dictionary of Kant and Kantianism, Second Edition contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 500 cross-referenced entries on key terms of Kant's philosophy.

We provide a brief overview of the shift toward the intrinsic view of brain activity, describing in particular the structural and functional connectivity patterns of the “Default mode network”. We then consider the Default mode network in a specifically cognitive setting and ask what changes the focus on the Default mode network and other sorts of intrinsic activity require from models put forward by cognitive neuroscientists.

One of the greatest challenges of consciousness research is to understand the relationship between consciousness and its implementing substrate. Current research into the neural correlates of consciousness regards the biological brain as being this substrate, but largely fails to clarify the nature of the brain-consciousness connection. A popular approach within this research is to construe brain-consciousness correlations in causal terms: the neural correlates of consciousness are the causes of states of consciousness. After introducing the notion of the neural correlate of (...) consciousness, we argue (in section 2) that this causal strategy is misguided. It implicitly involves an undesirable dualism of matter and mind and should thus be avoided. A non-causal account of the brain-mind correlations is to be preferred. We favor the theory of the identity of mind and brain, according to which states of phenomenal consciousness are identical with their neural correlates. Research into the neural correlates of consciousness and the theory of identity (in the philosophy of mind) are two major research paradigms that hitherto have had very little mutual contact. We aim to demonstrate that they can enrich each other. This is the task of the third part of the paper in which we show that the identity theory must work with a suitably defined concept of type. Surprisingly, neither philosophers nor neuroscientists have taken much care in defining this central concept; more often than not, the term is used only implicitly and vaguely. We attempt to open a debate on this subject and remedy this unhappy state of affairs, proposing a tentative hierarchical classification of phenomenal and neurophysiological types, spanning multiple levels of varying degrees of generality. The fourth part of the paper compares the theory of identity with other prominent conceptions of the mind-body connection. We conclude by stressing that scientists working on consciousness should engage more with metaphysical issues concerning the relation of brain processes and states of consciousness. Without this, the ultimate goals of consciousness research can hardly be fulfilled. (shrink)

This paper is a contribution to the development of fuzzy logic in narrow sense with evaluated syntax and connectives interpreted in Łukasiewicz algebra. The main results concern model theory of fuzzy logic and generalization of the Craig-Robinson's theorem on joint consistency of fuzzy theories as well as Craig's interpolation theorem.

The paper deals with fuzzy Horn logic which is a fragment of predicate fuzzy logic with evaluated syntax. Formulas of FHL are of the form of simple implications between identities. We show that one can have Pavelka-style completeness of FHL w.r.t. semantics over the unit interval [0, 1] with left-continuous t-norm and a residuated implication, provided that only certain fuzzy sets of formulas are considered. The model classes of fuzzy structures of FHL are characterized by closure properties. We also give (...) comments on related topics proposed by N. Weaver. (shrink)

Predictive Processing theory, hotly debated in neuroscience, psychology and philosophy, promises to explain a number of perceptual and cognitive phenomena in a simple and elegant manner. In some of its versions, the theory is ambitiously advertised as a new theory of conscious perception. The task of this paper is to assess whether this claim is realistic. We will be arguing that the Predictive Processing theory cannot explain the transition from unconscious to conscious perception in its proprietary terms. The explanations offer (...) by PP theorists mostly concern the preconditions of conscious perception, leaving the genuine material substrate of consciousness untouched. (shrink)

In this article we aim to reconstruct some aspects of Davidson's idea of triangulation, and against this reconstruction, ask whether the idea is viciously circular. We begin by looking at the claim that without a triangularn setting, there is no saying what the cause of a being's responses is. In the first section we discuss the notion of relevant similarity, and what difference the presence of a second non‐linguistic being could make for the individuation of a common focus of attention. (...) In the second section we look at the role of a second person in language‐acquisition. It is important that being corrected to ‘go on as others do’ does not yet presuppose thought, and similarity standards can be applied to a learner's reactions even before she is aware of these standards. We also show why Davidson is not committed to any consensus view of correctness. In the last section we discern three charges of circularity that can be levelled against the idea of triangulation. We argue that Davidson can respond to the first two charges, and point to a way of answering the third. But the response we propound raises a new question, namely, why does the second being have to be a speaker or thinker even before the learner is aware of the three points of the triangle? (shrink)

The present paper was written as a contribution to ongoing methodological debates within the NCC project. We focus on the neural correlates of conscious perceptual episodes. Our claim is that the NCC notion, as applied to conscious perceptual episodes, needs to be reconceptualized. It mixes together the processing related to the perceived contents and the neural substrate of consciousness proper, i.e. mechanisms making the perceptual contents conscious. We thus propose that the perceptual NCC be divided into two constitutive subnotions. The (...) main theoretical idea that emerges as a consequence of this reconceptualization is that the neural correlate of a perceptual episode is formed in the neural interaction between content-processing and consciousness-conferring mechanisms. The paper elaborates this distinction, marshals some initial arguments in its favour, and tests it against some of the most debated theories of consciousness. (shrink)

Media philosopher Vilém Flusser proposed a revolutionary new way of thinking about photography.

Two important questions arise concerning the properties that constitute the phenomenal characters of our experiences: first, where these properties exist, and, second, whether they are tied to our consciousness of them. Such properties can either exist externally to the perceiving subject, or internally to her. This article argues that phenomenal characters, and specifically the phenomenal characters of colours, may exist independently of consciousness and that they are internal to the subject. We defend this combination of claims against a recent criticism (...) according to which the unconscious phenomenal character of colours exists externally to the subject. We defend internalism about (potentially unconscious) phenomenal character by appealing to recent neuroscientific and behavioural evidence, and by rejecting the claim that externalism about phenomenal character is dialectically in a better position than internalism. In addition, we briefly present certain difficulties for externalist views of phenomenal character. These concern cases where the perceptual relation fails, but a perceptual experience still results. These points suffice to defuse the externalist critique of our view, and support the internalist variant of the consciousness-independence claim as the most plausible account of the unconscious phenomenal character of colours.

Ten years after his death, Vilém Flusser’s reputation as one of Europe’s most original modern philosophers continues to grow. Increasingly influential in Europe and Latin America, the Prague-born intellectual’s thought has until now remained largely unknown in the English-speaking world. His innovative writings theorize—and ultimately embrace—the epochal shift that humanity is undergoing from what he termed "linear thinking" toward a new form of multidimensional, visual thinking embodied by digital culture. For Flusser, these new modes and technologies of communication make (...) possible a society in which dialogue between people becomes the supreme value.The first English-language anthology of Flusser’s work, this volume displays the extraordinary range and subtlety of his intellect. A number of the essays collected here introduce and elaborate his theory of communication, influenced by thinkers as diverse as Martin Buber, Edmund Husserl, and Thomas Kuhn. While taking dystopian, posthuman visions of communication technologies into account, Flusser celebrates their liberatory and humanizing aspects. For Flusser, existence was akin to being thrown into an abyss of absurd experience or "bottomlessness"; becoming human required creating meaning out of this painful event by consciously connecting with others, in part through such technologies. Other essays present Flusser’s thoughts on the future of writing, the revolutionary nature of photography, the relationship between exile and creativity, and his unconventional concept of posthistory. Taken together, these essays confirm Flusser’s importance and prescience within contemporary philosophy.Vilém Flusser was born in Prague and taught philosophy in Brazil.

Gestures is a collection of essays that proposes a daring and ambitious new conception of human behavior. Defining gesture as “a movement of the body or of a tool attached to the body for which there is no satisfactory causal explanation,” Flusser moves around the topic from different points of view, angles and distances: sometimes he zooms in on a modest, ordinary movement like taking a photograph, shaving, or smoking a pipe. Sometimes he pulls back to look at something as (...) vast and varied as human “making,” embracing everything from the fashioning of simple tools to mass manufacturing. Holding firmly to basic phenomenological principles – that consciousness is always consciousness of something, that we know others by reference to ourselves, he claims that we constantly “read” states of mind, i.e. thoughts, intentions, emotions, from gestures; still we lack a theory about how this happens. Gestures takes a first step. It offers alternatives to theories by now so veiled by habit and myth that we are hardly conscious of them, and so hardly realize that they are failing. These include the assumption that we can “know” something without being affected by it, the belief that science is value-free, and the common conviction that science and art are fundamentally different activities.

In Post-History, Vilém Flusser asks the essential question: Is there any room left for freedom in a programmed world? Written as a series of lectures to be delivered at universities in Brazil, Israel, and France, this first English translation of Post-History brings to an anglophone readership Flusser's first critique of apparatus as the aesthetic, ethical, and epistemological model of present times.

In this collection of essays, experts in the field of consciousness research shed light on the intricate relationship between conscious and unconscious states of mind. Advancing the debate on consciousness research, this book puts centre stage the topic of commonalities and differences between conscious and unconscious contents of the mind. The collection of cutting-edge chapters offers a breadth of research perspectives, with some arguing that unconscious states have been unjustly overlooked and deserve recognition for their richness and wide scope. Others (...) contend that significant differences between conscious and unconscious states persist, highlighting the importance of their distinct characteristics. Explorations into the nature of the transition from unconscious to conscious mind further complicate the picture, with some authors questioning whether a sharp divide between unconscious and conscious states truly exists. Delving into ontological, epistemological, and methodological issues, this thought-provoking text challenges established paradigms and paves the way for a reimagining of consciousness research. It does so in an understandable and accessible way, making this a perfect companion to both experts and students of philosophy, psychology, and related fields. (shrink)

Abstract: Daniel Wegner’s theory of apparent mental causation is often misread. His aim was not to question the causal effectiveness of conscious mental states like intentions. Rather, he attempted to show that our subjective sense of agency is not a completely reliable indicator of the actual causality of action, and needs to be replaced by more objective means of inquiry.
