Se expone una reflexión acerca de los distintos tipos de propiedades fenomenológicas de algunos estados mentales, también conocidos como qualia, con el objetivo de identificar los roles que cumplen en la cognición. Para ello se releva primero el carácter cualitativo de la fenomenología, proponiéndose que conocer es un proceso que consiste en dar nuevos formatos a la experiencia a través de su progresiva explicitación. En segundo lugar, se analizan las características de dos diferentes tipos de qualia y sus papeles en (...) la cognición. Un primer tipo, de características intrinsecamente cognitivas, se encuentra asociado a las emociones y otros estados similares que participan como centro del pensamiento, producto de su posibilidad de acceso a la autoconsciencia. Un segundo tipo, conformado por qualia vinculados a la percepción, corresponde a fenomenología autoconscientemente inaccesible, razón por la cual juega un rol representacional que no depende de sus características cualitativas específicas.

Proponents of the hard problem of consciousness argue that the zombie and inverted spectrum thought experiments demonstrate that consciousness cannot be physical. They present scenarios designed to demonstrate that it is conceivable that a physical replica of someone can have radically different or no conscious experiences, that such an experience-less replica is possible and therefore that materialism is false. I will argue that once one understands the limitations that the physics of this world puts on cognitive systems, zombies and the (...) inverted spectrum are not conceivable. (shrink)

Resumen En el marco de la filosofía de la mente, este artículo aborda el problema de la causación mental en el proyecto naturalista biológico de John Searle. A partir de la concepción de la mente como un fenómeno emergente de procesos cerebrales, evalúo las críticas que Jaegwon Kim realiza a la eficacia causal de la consciencia, centrándome en los argumentos de sobredeterminación y violación del principio de clausura físico causal. Luego analizo el debate de la causación mental a partir de (...) los descubrimientos de Benjamin Libet respecto a la existencia de actividad neuronal pre-consciente en la conducta motora voluntaria. Dicha actividad, llamada potencial de preparación, junto a la noción de causación trabajada en neurociencia, avala la eficacia causal de los estados mentales, pero en un sentido distinto al propuesto por Searle.Within the framework of philosophy of mind, this paper addresses the problem of mental causation in John Searle's biological naturalist project. Beginning with the conception of the mind as a phenomenon emerging from cerebral processes, I evaluate the criticisms that Jaegwon Kim makes to the causal efficacy of consciousness, focusing on the arguments of overdetermination and violation of the principle of physical causal closure. Then, I analyze the debate on mental causation from the findings of Benjamin Libet regarding the existence of pre-conscious neural activity in voluntary motor behavior. This activity, called readiness potential, and the notion of causation worked in neuroscience, support the causal efficacy of mental states, but in a different sense from that proposed by Searle.

The paper discusses possible roles of consciousness in a semiotic activity of a cognitive agent. The discussion, we claim, is based on two related approaches to consciousness: on Chalmers’ theory of phenomenal and psychological consciousness and on Damasio’s neural theory, which draws a distinction between core and extended consciousness. Two stages of cognitive-semiotic processing are discussed: the moment of perception of a sign as a meaningful entity and the metasemiotic processes understood as the human capacity to reflect on signs and (...) their usage, analyse and control processes of recognition, interpretation of signs and to detect and correct errors in semiotic activity. In the case of the first stage, it is argued that signs as meaningful entities have a distincly experiential character. The feeling of meaningfulness is a result of phenomenal consciousness, in particular a result of the so-called valuation features of phenomenal experience. I claim that this aspect of cognitive-semiotic activity is possible owing to a special neural mechanism called a semiotic marker. It is argued that semiotic systems have to be able to use signs as signs, i.e. they should display some metacognitive capacities, in particular an ability to analyse semiosis at a metalevel. It is argued that such metasemiosis is dependent on psychological consciousness and is realized at the neural level in the form of extended consciousness. The paper is based on a particular understanding of cognitive semiotics as a discipline involving analyses of cognitive processes as semiotic processes, i.e. processes requiring usage of signs.

Communicative interactions across different species have so far received relatively little attention from cognitive or behavioral scientists. Most research in this area views the process of communication as the adaptive interaction of manipulative signalers and information-assessing receivers. This paper discusses some shortcomings of the information/influence model of communication, particularly in the empirical study of interspecific communicative interactions. It then presents an alternative theoretical model, based on recent contributions in psycholinguistics and semiotics. The semiotic alignment model views communication as a dynamic (...) process of joint semiosis resulting in the alignment of the interactants’ own-worlds (Umwelten). It is argued that this model can improve our understanding of communicative interactions between heterospecifics and provide the basis for future work in the empirical study of interspecific communication.

There is presently an ongoing debate about the relation between attention and consciousness, fuelled by results from paradigms which probe the interaction between these two faculties, such as the attentional blink, object substitution masking and change blindness. Simulations of these paradigms were shown recently to be able to provide an explanation of them from a single overarching control model of attention. This model furthermore allows exploration of how consciousness might be created as a copy of the attention movement control signal, (...) and indicates the complex possibilities inherent in attention. The paper develops this theme and presents a set of questions and their possible answers arising from the need for the existence of a set of inner selves associated with different attention copy signals in different modalities to provide a unified phenomenological experience. The paper concludes with a set of comments on the Hilbert questions of the Special Issue. (shrink)

The ‘mineness’ of thoughts has often been accepted as indubitable in philosophy. However, the symptom of thought insertion in schizophrenia seems to be an empirical counterexample to the dictum that every introspected thought is one's own. We present a thorough conceptual analysis of mineness of thought, distinguishing between ownership and authorship . We argue that it is indeed a conceptual truth that introspected thoughts are owned by the introspector. However, there are everyday and pathological cases of thoughts, for which we (...) do not ascribe authorship to ourselves. To explain inserted thoughts, however, we need an additional factor which is constituted by the lack of control over inserted thoughts . We present a review of empirical data on thought control and thought insertion in the light of the conceptual analysis. We conclude with a summary of the most important future direction of research.

U članku se kroz višedisciplinarni pristup kognitivnih znanosti proučava osobito ljudsko iskustvo povezano s religioznim doživljajem stvarnosti, koje se u tradiciji discipline povijesti religija naziva ‘iskustvo svetoga’. U skladu s teorijom emergencije, predlaže se definicija iskustva svetoga kao stanja svijesti sa subjektivnom kvalitetom integracije, specifičnim neurološkim korelatom i funkcionalnim obilježjima. Emergentne teorije svijesti pružaju ontološki ujednačeno tumačenje iskustava svetoga nudeći »naravna« objašnjenja bez odricanja njihove fenomenološke subjektivnosti. Prijenos iskustva svetoga iz unitarnoga, svojevrsnog intencionalno neobojenoga stanja, u izrecivi jezični kôd intencionalno (...) relevantnih pojmova sa sveprožimajućim utjecajima na opojmljivanje svijeta razmatra se pomoću kognitivne jezične teorije u tradiciji Johnsona i Lakoffa. Sposobnost izricanja značenja iskustva svetoga sagledava se kao emergentno svojstvo pojmovnog procesuiranja metaforičkoga razmišljanja uvjetovanoga utjelovljenošću uma i kulturalnim odrednicama. Predloženi pristup omogućuje tumačenje nastanka složenih mitoloških i kulturalnih modela temeljem iskustva svetoga, ali i ukazuje na njegovu kulturalnu neuvjetovanost zadanu nediskurzivnom naravi samog iskustva.In this article a multidisciplinary approach of cognitive sciences is employed for the analysis of a special category of human experience related to the religious understanding of the world, termed according to the History of Religion as the ‘experience of sacred’. The experience of sacred is defined as the state of consciousness with a subjective quality of integration, a specific neural correlate and functional features. Emergentist theory of consciousness provides ontologically consistent perspective offering a “natural” explanation for this type of experience without denying its subjective phenomenology. The linguistic expression of the experience is examined in the light of Johnson’s and Lakoff’s cognitive linguistic theory. The linguistic competence enabling the expression of the sacred experience is defined as the emergent property of conceptual processing of metaphorical thinking shaped by the embodied mind. This approach explains the seminal role of the experience of sacred in the formation of complex mythological and cultural models, but also points to its non discursive nature. (shrink)

In this model consciousness is a form of memory. We are essentially “living in the past” as our experience, the qualia, is always of past events. Consciousness represents the storage of past events for use in future situations and it is altered by external experience of the organism. Psychological frameworks of conditioning and learning theory are used to explain this model along with recent neuropsychological research on synaesthesia and phantom limb pain. Consciousness results from the gradual evolutionary development of the (...) human information processing function. Language is hypothesised to have evolved at a pre-conscious stage of human development as a function of the need for ‘within-organism’ data storage. Communication with others may not have been the initial evolutionary advantage conferred by language. The later incidental use of language as a communication tool, which results in the reflecting back of one’s experience through others, is what has triggered a conscious experience. (shrink)

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

The anthropology of consciousness is a field of enormous and demanding scope. In this article, there is no attempt to address all of the current trends in thinking and research; rather, the aim was to draw a line through the field that extends from the 19th century and European philosophies to some contemporary expressions of those philosophies in social science research. In particular, taking the original project of Edmund Husserl, an approach to the phenomenological investigation of the nature of consciousness (...) and, in addition, states of consciousness is proposed in the form of “existential grammars.” The treatment is propaedeutic: The ideas presented here are part of an on-going, long-term project tied to cross-cultural and experimental research on consciousness. However, the short-term outcomes are promising in elucidating the foundational questions not only about consciousness but also about specific areas of interest such as healing and the nature of scientific investigation itself. One important direction in this work is to illuminate, where possible, the pre-reflective rationalities of human experience, of consciousness itself, in such a way that we might generate codes of consciousness ultimately not as the equivalent of genetic models, but as descriptors of the core matrix of consciousness out of which alterations of consciousness might be better understood.

Experiences of qualia, subjective sensory-like aspects of stimuli, are central to imagistic representation. Following Raffman , qualia are considered to reflect experiential knowledge distinct from descriptive, abstract, and propositional knowledge; following Jackendoff , objective neural activity is distinguished from subjective experience. It is argued that descriptive physical knowledge does not provide an adequate accounting of qualia, and philosophical scenarios such as the Turing test and the Chinese Room are adapted to demonstrate inadequacies of accounts of cognition that ignore subjective experience. (...) Arguments by Dennett and others that qualia do not exist or that qualia do not provide additional explanatory power are addressed, and it is suggested that consideration of qualia is necessary in order to explain objective behavior. The hypotheses of functional equivalence, second-order isomorphism, and psychophysical complementarity between imagery and perception are discussed, and the ability of analog and schematic models of imagery to account for qualia is examined.

It is sometimes claimed that ordinary objects, such as mountains and chairs, are not material in their own right, but only in virtue of the fact that they are constituted by matter. As Fine puts it, they are “only derivatively material” (2003, 211). In this paper I argue that invoking “constitution” to account for the materiality of things that are not material in their own right explains nothing and renders the admission that these objects are indeed material completely mysterious. Although (...) there may be metaphysical contexts in which mysterianism can be accepted with equanimity, I further argue, the question of the materiality of quotidian objects is not one of them.

Many debates about consciousness appear to be endless, in part because of conceptual confusions preventing clarity as to what the issues are and what does or does not count as evidence. This makes it hard to decide what should go into a machine if it is to be described as 'conscious'. Thus, triumphant demonstrations by some AI developers may be regarded by others as proving nothing of interest because the system does not satisfy *their* definitions or requirements specifications.

This article is devoted to the conceptual analysis of two texts of leading scholars in cognitive neuroscience and its philosophy, Patricia Churchland and Eric Kandel. After a short introduction about the notion of reduction, I give a detailed account of the way both scientists view the relationship between theories about brain functioning on the one hand and consciousness and psychopathology, respectively, on the other hand. The analysis not only reveals underlying philosophical mind/brain conceptions and their inner tensions, but also the (...) conceptual relevance of distinctions that are fundamental in the work of Dooyeweerd, such as the distinction between modes and entities, between law and subject and between subject function and object function. After a brief clarification of the way these distinctions function in Dooyeweerd’s theory of the body as an ‘enkaptic structural whole’, I try to explain how the conceptual framework, developed here, could be applied to brain functioning and leads to greater clarity in neuroscientific theorizing.
