Block's notion of P-consciousness catches too much in its net. He would do better to exclude all states that do not have a sensory component. I question what he says about my work with the “blind” monkey, Helen.

Would a history of the human sciences seem strange if it featured a chapter on the history of consciousness? An argument for including such a chapter could point out that consciousness is often thought to be essential to what it is to be human. Yet the discipline that makes this.

It is accepted that “primary awareness” may emerge from the integration of two classes of information. It is unclear, however, why this cannot take place within the comparator rather than in conjunction with feedback to the perceptual systems. The model has plausibility in relation to the continuity of conscious experience in the normal waking state and may be extended to encompass certain aspects of the “sense of self” which are frequently disrupted in psychotic patients.

A “fallacy” is something like the sense-datum fallacy, involving a logically invalid argument. A “conflation” is something like Block's conflation of the (alleged) raw feel of an experience with what it is like to have the experience. Trivially, a self is conscious of something only if it accesses it. Substantive issues concern the nature of the conscious self and the nature of access.

‘Naturalized’ philosophers of mind regularly appeal to the empirical psychological literature in support of the ‘theory-theory’ account of the natural epistemology of mental state ascription (to self and others). It is argued that such appeals are not philosophically neutral, but in fact presuppose the theory-theory account of mental state ascription. It is suggested that a possible explanation of the popularity of the theory-theory account is that it is generally assumed that alternative accounts in terms of introspection (and simulation) presuppose a (...) discredited ‘inner ostensive definition’ account of the meaning of mental state terms. However, the inner ostensive definition account is not the only alternative to the theory-theory account of the meaning of mental state terms, and commitment to a theory-theory account of the meaning of mental state terms does not mandate commitment to a theory-theory account of the epistemology of mental state ascription.

In this paper it is argued that the experimental data on commissurotomy patients provide no grounds for denying the singular personhood of commissurotomy patients. This is because, contrary to most philosophical accounts, there is no “unity of consciousness” discriminating condition for singular personhood that is violated in the case of commissurotomy patients, and because no contradictions arise when singular personhood is ascribed to commissurotomy patients.

Drawing on previous models of anxiety, intermediate memory, the positive symptoms of schizophrenia, and goal-directed behaviour, a neuropsychological hypothesis is proposed for the generation of the contents of consciousness. It is suggested that these correspond to the outputs of a comparator that, on a moment-by-moment basis, compares the current state of the organism's perceptual world with a predicted state. An outline is given of the information-processing functions of the comparator system and of the neural systems which mediate them. The hypothesis (...) appears to be able to account for a number of key features of the contents of consciousness. However, it is argued that neitherthis nor any existing comparable hypothesis is yet able to explain why the brain should generate conscious experience of any kind at all. (shrink)

Should we distinguish between access and phenomenal consciousness? Block says yes and that various pathologies of consciousness support and clarify the distinction. The commentary charge that the distinction is neither supported nor clarified by the clinical data. It recommends an alternative reading of the data and urges Block to clarify the distinction.

The first claim in the target article was that there is as yet no transparent, causal account of the relations between consciousness and brain-and-behaviour. That claim remains firm. The second claim was that the contents of consciousness consist, psychologically, of the outputs of a comparator system; the third consisted of a description of the brain mechanisms proposed to instantiate the comparator. In order to defend these claims against criticism, it has been necessary to clarify the distinction between consciousness-as-such and the (...) contents of consciousness, to widen the description of the neural machinery instantiating the comparator system, and to clarify the relationship between the contents of consciousness in the here-and-now and episodic memory.

The conservation laws do not establish the central premise within the argument from causal overdetermination – the causal completeness of the physical domain. Contrary to David Papineau, this is true even if there is no non-physical energy. The combination of the conservation laws with the claim that there is no non-physical energy would establish the causal completeness principle only if, at the very least, two further causal claims were accepted. First, the claim that the only way that something non-physical could (...) affect a physical system is by affecting the amount of energy or momentum within it, or redistributing the energy and momentum within it. Second, the claim that redistribution of energy and momentum cannot be brought about without supplying energy or momentum. Both of these claims, however, are exceedingly difficult to defend in the context of the argument. (shrink)

Metaphors of mind and their elaboration into models serve a crucial explanatory role in psychology. In this article, an attempt is made to describe how biology and engineering provide the predominant metaphors for contemporary psychology. A contrast between the discursive and descriptive functions of metaphor use in theory construction serves as a platform for deliberation upon the pragmatic consequences of models derived therefrom. The conclusion contains reflections upon the possibility of an integrative interdisciplinary psychology.

Gray has expanded his account of schizophrenia to explain consciousness as well. His theory explains neither phenomenon adequately because he treats individual minds in isolation. The primary function of consciousness is to permit high level interactions with other conscious beings. The key symptoms of schizophrenia reflect a failure of this mechanism.

Because consciousness has an organizational, or functional, center, Gray supposes that there must be a corresponding physical center in the brain. He proposes further that since this center generates consciousness, ablating it would eliminate consciousness, while leaving behavior intact. But the center of consciousness is simply the product of the functional linkages among sensory input, memory, inner speech, and so on, and behavior.

The Modularity of Mind proposes an alternative to the or view of cognitive architecture that has dominated several decades of cognitive science. Whereas interactionism stresses the continuity of perceptual and cognitive processes, modularity theory argues for their distinctness. It is argued, in particular, that the apparent plausibility of New Look theorizing derives from the failure to distinguish between the (correct) claim that perceptual processes are inferential and the (dubious) claim that they are unencapsidated, that is, that they are arbitrarily sensitive (...) to the organism's beliefs and desires. In fact, according to modularity theory, perceptual processes are computationally isolated from much of the background knowledge to which cognitive processes have access. The postulation of autonomous, domain-specific psychological mechanisms underlying perceptual integration connects modularity theory with the tradition of faculty psychology, in particular, with the work of Franz Joseph Call. Some of these historical affinities, and some of the relations between faculty psychology and Cartesianism, are discussed in the book. (shrink)

A hybrid theory is any moral theory according to which different classes of individuals ought to be treated according to different principles. We argue that some hybrid theories are able to meet standards of psychological plausibility, by which we mean that it’s feasible for ordinary human beings to understand and act in accord with them. Insofar as psychological plausibility is a theoretical virtue, then, such hybrid theories deserve more serious consideration. To make the case for this view, we explain what (...) psychological plausibility is and why we might value it, why the human/animal divide appears to be an entrenched feature of human psychology, and why Robert Nozick’s hybrid theory doesn’t go far enough. Finally, we make the case that a more promising psychologically plausible hybrid theory, with respect to humans and animals, will be (at least) at tribrid theory—that is, positing three domains rather than two.

This paper critically examines Ken Wilber's transpersonal evolutionary theory in the context of the philosophical discourse of postmodernity. The critique focuses on Wilber's refutation of non?absolutist and non?universalist approaches to rationality, truth, and morality?such as cultural relativism, pluralism, constructivism or perspectivism?under the charges of being epistemologically self?refuting and morally pernicious. First, it is suggested that Wilber offers a faulty dichotomy between his absolutist?universalist metanarrative and a self?contradictory and pernicious vulgar relativism. Second, it is shown that Wilber's arguments for the self?refuting (...) and pernicious nature of other non?absolutist approaches are both fallacious and distorting. Finally, the problematic consequences of absolutist discourse for academic and cross?cultural dialogue are pinpointed. Taking Wilber's treatment of Nagarjuna's thinking as a paradigmatic example, it is suggested that absolutist thinking both usually leads to ?bad? hermeneutics, and potentially hinders genuine dialogue among people and traditions holding different world views.

Although not the main point of his target article, Block defends the view that perception and awareness of perception could be functions of different brain systems. I will argue that the available data do not support this view, and that Block's defense of the view rests on problematic eonstruals of the “executive system” and of the components of information-processing models.

Evangelical scholars have recently offered criticisms of mind-body dualism from the disciplines of theology, philosophy, and neuroscience. We offer several arguments as to why these reasons for abandoning mind-body dualism fail. Additionally, we offer a positive thesis, a dualism that brings together the best aspects of the Cartesian view and the Thomistic view of human persons. The result is a substance dualism that treats the nature of embodiment quite seriously. This view explains why we, as souls, require a resurrected body (...) as well as accounting for the great good of our embodiment in general. A human person is at the same time wholly soul and yet fully bodily. (shrink)

The commentary argues that we cannot be sure that human consciousness has survival value and that in order to understand the origins and, perhaps, the function of consciousness, we should examine the behavioural and neural precursors to consciousness in nonhumans. An example is given of research on the role of context in decisions regarding fleeing from probable predators in the Mongolian gerbil.

Gray's account is remarkable in its depth and scope but too little attention is paid to poor correspondences with the literature on hippocampal/subicular damage, the theta rhythm, and novelty detection. An alternative account, focusing on hippocampal involvement in organizing memories in a way that makes them accessible to conscious recollection but not in access to consciousness per se, avoids each of these limitations.

Propositions as to the nature of consciousness, based on disorders of perception that result from brain damage, and taking insufficient account of the numerous ways in which normal subjects may deviate from that “usual” sequence of events (input → subjective awareness → output) risk increasing rather than diminishing any existing confusion about the function of consciousness.

The notion of unconscious finds support in many experimental studies that use the dissociation method. This method allows us to distinguish between conscious and unconscious mental states when participants cannot explain why they performed as they did in an experiment. The paper will discuss the notion of unconscious by considering David R. Shanks’ criticisms of the application of the dissociation method: it will assess three studies Shanks proposes as reexaminations of three other relevant studies in the literature and show how (...) Shanks’ work provides an examination of the methodological pitfalls of such studies. The paper will argue that, although Shanks’s results are relevant regarding theories about the structure of cognition, his theoretical positions are at best confused and at worst diminish the importance of his research outcomes. It will conclude by showing why Shanks’s results that legitimize the role of consciousness in cognition can be problematic for the physicalistic or materialistic framework endorsed by cognitive psychologists. Keywords: Dissociation Method; Dual-process Theories; Cognitive Psychology; Consciousness; Unconscious La distinzione tra cognizione conscia e inconscia nell’opera di D.R. Schanks: una valutazione critica Riassunto: La nozione di inconscio trova supporto in vari studi sperimentali che utilizzano il metodo della dissociazione. Secondo la letteratura cognitivista questo metodo permette di distinguere tra stati mentali consci e inconsci quando i partecipanti non sono in grado di riportare verbalmente il perché si sono comportati in un certo modo durante l’esecuzione di un compito sperimentale. Il presente articolo discute la nozione di inconscio in relazione alle critiche di David R. Shanks all’applicazione del metodo della dissociazione. Più precisamente, esso valuta tre studi che Shanks propone come repliche e rivalutazioni di altrettante ricerche a favore della cognizione inconscia e mostra l’autore riesca con successo a metterne in luce le carenze metodologiche. Inoltre, sostiene anche che, sebbene i risultati sperimentali di Shanks siano importanti per le teorie sulla struttura della cognizione, le sue posizioni teoriche sono quantomeno confuse e rischiano di ridimensionare la portata delle sue conclusioni empiriche e metodologiche. L’articolo conclude mostrando le ragioni per cui i risultati di Shanks, che legittimano il ruolo della coscienza nella cognizione, siano controversi in quanto adottano una posizione filosofica fisicalistica o materialistica comune alla maggioranza degli psicologi cognitivi.

A tradition of work in cognitive science indicates that much of our mental lives is not available to introspection . Though the researchers often present these results as surprising, little has been done to explore the degree to which people presume introspective access to their mental events. In this paper, we distinguish two dimensions of introspective access: the power of access, i.e. whether people believe they can unfailingly or only typically introspect mental events; and the domain of access, i.e. what (...) types of mental events people believe they are able to introspect. We report five experiments carried out to discover where lay beliefs about introspection fall on these dimensions. In our experiments, people did not presume universal introspective access, but they did overestimate the amount of access they actually have, particularly in the case of decisions. (shrink)

The nominal ground that entwines human beings and animal behaviours is unwilling to admit moral valuing as a non-human act. Just to nail it down explicitly, two clauses ramify the moral conscience of human beings as follows: a) Can non-humans be moral beings?, b) Unconscious animal behaviours go beyond any moral judgments. My approach aims to rebuff these anthropomorphic clauses by justifying animals’ moral beings and animals’ moral behaviours from a meta-ethical stance. A meta-ethical outlook may enable an analysis of (...) ethical and normative views through the limit of moral motives and reasoning. Animals’ sense of moral motives and their apparatus of getting involved in moral acts cannot be compared with human actions. In human moral engagement, we abide by moral paradigmatic theories and their diversified attitudes that could have conceptual and linguistic use in our societal discourses. However, animals’ intentional apparatus may have the propensity to choose an act following the moral consequences (care, utility, responsibility, etc.) in their life-forms. (shrink)

The central fact in the delineation of radical behaviorism is its conceptual avoidance of propositional content. This eschewal of the intentional stance sets it apart not only from cognitivism but from other non-behaviorisms. Indeed, the defining characteristic of radical behaviorism is not that it avoids mediating processes per se but that it sets out to account for behavior without recourse to propositional attitudes. Based, rather, on the contextual stance, it provides definitions of contingency-shaped, rule-governed verbal and private behaviors which are (...) non-intentional. However, while the account provided by radical behaviorism fulfills the pragmatic criteria of prediction and control of its subject matter, it has problems of explanation that stem from the failure of radical behaviorist interpretation to address the personal level of analysis, to provide for the continuity of behavior, and to show how its accounts can be delimited in the face of causal equifinality. This leaves gaps in its explanation that radical behaviorists choose either to ignore or to fill with the very intentional locutions that they formally abhor but which I argue are essential. As a result, many psychologists who style themselves radical behaviorists have already moved beyond radical behaviorism as a philosophy of science. They have done so primarily as a result of adopting the language of intentional psychology in order to explain behavior; where they have not done this, they have resorted to the unscientific assumption that somewhere there is a learning history that explains their data. While it is indeed the case that a learning history precedes all operant behavior, the explanatory gap that is revealed by the search for this unobtainable information reveals the inescapability of intentionality. Hence, psychologists, including radical behaviorists, are right to employ it. The challenge is to understand why this is so and to celebrate rather than denigrate the resulting extension of behavioral science. In this response, I first raise and seek to answer two questions: what is radical behaviorism, and what is intentional explanation? I go on to discuss the incompleteness of radical behaviorism. There follows a summary of the argument with respect to intentional behaviorism and super-personal cognitive psychology. And, finally, I bring the discussion back to Daniel Dennett, the philosopher who initiated so much of it. (shrink)

Focusing on the manifesto provided by Gallagher and Zahavi's The Phenomenological Mind, this paper critically examines how we should understand and asses the prospects of allying phenomenological approaches to mind with work in the cognitive sciences. It is argued that more radical and revolutionary adjustments to our standard conceptions of the mind than suggested by (at least some) the proponents of the phenomenological movement are required before such alliances will bear fruit.

I examined the proposition that there are psychological limits on what scientific problems can be solved, and that these limits may be based on a failure to be able to produce imagable, observation-based models for any possible solution, a position suggested by philosopher Colin McGinn in an argument attempting to prove that the mind-body problem is unsolvable. I examined another likely candidate for an unsolvable problem -- the ultimate origin of the universe (i.e., what might have preceded the Big Bang (...) or any other starting point; why there should be something rather than nothing) -- by exploring the reasoning of physicists about this problem and measuring visual imagery frequency and vividness, with the expectation that those who most believed the problem unsolvable would be more frequent/vivid imagers and therefore more affected by the apparent impossibility of producing an imagable solution. Eight physicists were interviewed and imagery frequency and vividness measurements performed using Cohen & Saslona's IDQ-IHS and Marks's VVIQ, respectively. All subjects considered the problem unsolvable within today's physics and all but one thought the problem still meaningful, though none were optimistic about a solution. The one subject who dismissed the problem had the lowest imagery frequency score, and there was also a significant rank order correlation (r = 0.83, p < .02) between degree of belief in problem unsolvability (extended to include viewing the problem as meaningful and not already solved) and a composite imagery frequency/vividness score, though the sample was too small to control for some possible confounding factors.

One of the most serious challenges (if not the most serious challenge) for interactive psycho-physical dualism (henceforth interactive dualism or ID) is the so-called ‘interaction problem’. It has two facets, one of which this article focuses on, namely the apparent tension between interactions of non-physical minds in the physical world and physical laws of nature. One family of approaches to alleviate or even dissolve this tension is based on a collapse solution (‘consciousness collapse/CC) of the measurement problem in quantum mechanics (...) (QM). The idea is that the mind brings about the collapse of a superposed wave function onto one of its eigenstates. Thus, it is claimed, can the mind change the course of things without violating any law figuring in physical theory. I will first show that this hope is premature because energy and momentum are probably not conserved in collapse processes, and that even if this can be dealt with, the violations are either severe or produce further ontological problems. Second, I point out several conceptual difficulties for interactionist CC. I will also present solutions for those problems, but it will become clear that those solutions come at a high cost. Third, I shall briefly list some empirical problems which make life even harder for interactionist CC. I conclude with remarks about why no- collapse interpretations of QM don’t help either and what the present study has shown is the real issue for ID: namely to find a plausible integrative view of dualistic mental causation and laws of nature.

In this thesis I set forth what I understand to be the criteria of a Christian anthropology. From this, I then evaluate the major anthropological systems that Christians tend to employ to develop their accounts of human persons, with special attention given to Christian materialism, substance dualism, and Thomistic hylomorphism. I contend that neither Christian materialism nor substance dualism adequately satisfy the criteria of a Christian anthropology, and that some of the best examples of these perspectives have unique philosophical problems (...) of their own. I then consider Thomas Aquinas’s hylomorphic account of human persons and argue that, while it does not perfectly satisfy the criteria of a Christian anthropology, it does fair better than both Christian materialism and substance dualism, and that there are ways to modify his account to enable it to better satisfy the Christian criteria.
