To address the problems of both structured coordination of linked and modularised ontologies and to query a large dynamic ontology system, we propose a basic granularity framework and a set of functions to query such a granulated system. The granularity framework enforces a constrained and structured modularization. This facilitates automation of both dividing a large body of represented information as well as relinking the pieces. The functions enable basic cross-granular querying in a transparent and scalable way, as they rely on (...) the unambiguous management layer provided by the granularity framework, and are reusable for ontologies represented and stored in different formats.

An essential aspect of conceptual data modeling methodologies is the language’s expressiveness so as to represent the subject domain as precise as possible to obtain good quality models and, consequently, software. To gain better insight in the characteristics of the main conceptual modeling languages, we conducted a comparison between ORM, ORM2, UML, ER, and EER with the aid of Description Logic languages of the DLR family and the new formally defined generic conceptual data modeling language CMcom that is based on (...) DLRifd. ORM, ER, EER, and UML class diagrams are proper fragments of ORM2 and CMcom has the most expressive common denominator with these languages. CMcom simplifies prospects for automated, online, interoperability among the considered languages so that modelers not only can continue using their preferred modeling language yet be compatible with the other ones, but also have a common ground that eases database and software integration based on commonly used conceptual data models.

Few ontologies in the ecological domain exist, but their development can take advantage of gained experience in other domains and from existing modeling practices in ecology. Taxonomies do not suffice because more expressive modeling techniques are already available in ecology, and the perspective of flow with its centrality of events and processes cannot be represented adequately in a taxonomy. Therefore, formal ontologies are required for sufficient expressivity and to be of benefit to ecologists, which also enables future reuse. We have (...) created a formal mapping between the software-supported ecological modeling method and software tool STELLA and ontology elements, which simplifies bottom-up ontology development considerably and has excellent potential for semi-automated ontology development. However, the conducted experiments also revealed that ontology development for ecology is close to being part of ecological research that through the formalized representation of the knowledge more clearly points to lacunas and suggestions for further research in ecology.

My purpose in this book is to reach a more general audience than I have been able to reach through my publications in academic journals, such as Environmental Ethics. The strategy of the book is to use a lyrical personal narrative to motivate chapters advancing the case for the intelligence of all living things, our kinship with, similarities to, and dependency upon other life forms, and an ethic of respect for life. It includes a critique of biocidal aspects of our (...) culture, especially as it pertains to land use. The narrative chapters describe the process through which I became aware of the depth and pervasiveness of the environmental crisis and what I have learned through three decades of effort at ecological restoration of twenty-one acres of ruined land. The narrative chapters are used to motivate scientific descriptions of, and philosophical reflection on, various domains of life: the intelligence of insects, the analogy between soil ecosystems and the human microbiome, the inner lives of animals, and the intelligence of plants, as well as the human dependency upon healthy ecosystems—both material (through ecosystem services) and spiritual. The book calls for a radical reorientation of our attitudes and reforms in the institutions governing land use. (shrink)

In this paper I consider the way in which divinity is realized through an imaginary locus in the mystical thought of Jewish kabbalah and Hindu tantra. It demonstrates a reflective consciousness by the adept or master in understanding the place of God’s being, as a supernal and mundane reality. For the comparative assessment of these two distinctive approaches I shall use as a point of departure the interpretative strategies employed by Elliot Wolfson in his detailed work on Jewish mysticism. He (...) argues that there is an androcentric bias embedded in the speculative outlook of medieval kabbalah, as he reads the texts through a psychoanalytic lens. In a similar way, I will argue that there is an androcentric bias to the speculations presented in medieval Shaiva tantra, in particular that division known as the Trika. Overall, my aim is to suggest some functional and perhaps structural similarities to the characterization of divinity in these two traditions, through brief analyses of the erotic understanding of the nature of the Godhead.

Weak measurements offer new insights into the behavior of quantum systems. Combined with post-selection, quantum mechanics predicts a range of new experimentally testable phenomena. In this paper I consider weak measurements performed on time-dependent pre- and post-selected ensembles, with emphasis on the decay of excited states. The results show that the standard exponential decay law is a limiting case of a more general law that depends on both the time of post-selection and the choice of final state. The generalized law (...) is illustrated for two interesting choices of post-selection. (shrink)

Humans and other animals are capable of thought, emotion, consciousness, and understanding. Galaxies, trees, rocks, and chairs are not. Why is this? Is it merely that we are more complicated, or that we are made out of a different kind of material? Or is it that we are not entirely material at all? That is, what does it mean to say that something has a mind? In this course, we will focus on the mind-body problem, the question of how the (...) mind is related to the body, but we will also address a number of related questions: Can computers think? How is it that our thoughts manage to be about other things? What is the nature of consciousness? What do psychology, neuroscience, and artificial intelligence have to tell us about the fundamental nature of the mind? (shrink)

Among the most important questions still facing human enquiry are those about the mind and its place in nature. What is mind, and what is it relation to body? How should we best understand our common sense concepts of such mental phenomena as belief, desire, intention, emotion, reason and memory? How does the grey matter of the brain give rise to our rich and vivid experiences of colour, sound, texture, taste and smell?

A recurring problem in conceptual modelling and ontology development is the representation of part-whole relations, with a requirement to be able to distinguish between essential and mandatory parts. To solve this problem, we formally characterize the semantics of these shareability notions by resorting to the temporal conceptual model E RVT and its formalization in the description logic DLRUS.

One of the relations used with granularity is indistinguishability, where distinguishable entities in a finer-grained granule are indistinguishable in a coarser-grained granule. This relation is a subtype of equivalence relation, which is used in the other direction to create finer-grained granules. Together with the notion of similarity, we formally prove some intuitive properties of the indistinguishability relation for both qualitative and quantitative granularity, that with a given granulation there must be at least two granules (levels of granularity) for it to (...) be granular, and derive a strict order between finer and coarser granules. Based on these results, granulation hierarchy is defined as extra assisting structure to augment implementations. (shrink)

From the side of modelers and early-adopter industry, interest in reasoning over conceptual models and other online usage of conceptual models is growing. To obtain a more precise insight in the characteristics of the main conceptual modeling languages, we define the (semi-)standardized ORM, ORM2, UML, ER, and EER diagram languages in terms of the new generic conceptual data modeling language CMcom that is based on the DL language DLRifd. CMcom has the most expressive common denominator with these languages. CMcom advances (...) prospects for automated, online, interoperability among diverse conceptual data models and ensures compatibility with and between industrygrade conceptual data modeling languages.

This week saw the beginning of an action for libel brought by one historian against another over a question of history. The right-wing historian David Irving says the Holocaust was not as bad as has been claimed; he is suing American historian Deborah Lipstadt for calling him "a dangerous spokesman for Holocaust denial." The case, and its explosive content, remind us that history matters.

There are two likely paths for philosophers to follow in their encounters with Artificial Life: they can see it as a new way of doing philosophy, or simply as a new object worthy of philosophical attention using traditional methods. Is Artificial Life best seen as a new philosophical method or a new phenomenon? There is a case to be made for each alternative, but I urge philosophers to take the leap and consider the first to be the more important and (...) promising. (shrink)

As of January 25, 2006, readers have identified the following errors in Darwin's Dangerous Idea. (I have considered other criticisms offered by readers, but decided that they were in error. Further criticisms are, of course, invited.).

Three critics of Freedom Evolves (Dennett 2003) bring out important differences in philosophical outlook and method. Mele's thought experiments are supposed to expose the importance, for autonomy, of personal history, but they depend on the dubious invocation of mere logical or conceptual possibility. Fischer defends the Basic Argument for incompatibilism, while Taylor and I choose to sidestep it instead of disposing of it. Where does the burden of proof lie? O'Connor's candid expression of allegiance to traditional ideas that I reject (...) highlights a fundamental difference in assumptions about how—and why—to do philosophy. There are indeed definable varieties of free will that are incompatible with determinism. Do they matter? I have argued, against philosophical tradition, that they don't. (shrink)

The vivid terms, "Top-down" and "Bottom-up" have become popular in several different contexts in cognitive science. My task today is to sort out some different meanings and comment on the relations between them, and their implications for cognitive science.

Multiple different understandings and uses exist of what granularity is and how to implement it, where the former influences success of the latter with regards to storing granular data and using granularity for reasoning over the data or information. We propose a taxonomy of types of granularity and discuss for each leaf type how the entities or instances relate within its granular level. Such unambiguous distinctions can guide a conceptual modeler to better distinguish between the types of granularity and the (...) software developer to improve on implementations of granularity.

Several philosophers have developed accounts to dissolve the apparent conflict between deterministic laws of nature and objective chances. These philosophers advocate the compatibility of determinism and chance. I argue that determinism and chance are incompatible and criticize the various notions of “deterministic chance” supplied by the compatibilists. Many of the compatibilists are strongly motivated by scientific theories where objective probabilities are combined with deterministic laws, the most salient of which is classical statistical mechanics. I show that, properly interpreted, statistical mechanics (...) is either an indeterministic theory or else its probabilities are not chances, just as incompatibilism demands. (shrink)

Anti-reductionists hold that special science explanations of some phenomena are objectively better than physical explanations of those phenomena. Prominent defenses of this claim appeal to the multiple realizability of special science properties. I argue that special science explanations can be shown to be better, in one respect, than physical explanations in a way that does not depend on multiple realizability. Namely, I discuss a way in which a special science explanation may be more abstract than a competing physical explanation, even (...) if it is not multiply realizable, and I argue that this kind of abstraction can be used to support the idea that that special science explanation omits explanatorily irrelevant detail.

When people die in an accident, suddenly and unexpectedly, with a terrible arbitrariness that seems unjust and cruel beyond description, there seem to be very few consolations for those left behind. That is how it must seem to those bereaved by the Paddington rail disaster last week. In such cases there is no preparation, as with someone long ill; no sense of the quiet inevitability of great age; there is no closure, no proper leave-taking. Too much is left unfinished and (...) unsaid. Even when soldiers go to war, the possibility of their never returning gives a significance to the farewells on the day they left, and that fact brings comfort later. What intensifies the tragedy of sudden accidental death is that none of these helps is available. (shrink)

There are few successful applications of automated reasoning over OWL-formalised bio-ontologies, and requirements are often unclearly formulated. Of what is available, usage and prospective scenarios of automated reasoning is often different from the straightforward classification and satisfiability. We list nine types of scenarios and specify the requirements in more detail. Several of these requirements are already possible in practice or at least in theory, others are in need of further research, in particular regarding the linking of the OWL ontology to (...) data, reasoning over roles, and dynamically linking modular ontologies.

Implementing an algorithm on part of our causally-interconnected physical environment requires three choices that are typically considered arbitrary, i.e. no single option is innately privileged without invoking an external observer perspective. First, how to delineate one set of local causal relationships from the environment. Second, within this delineation, which inputs and outputs to designate for attention. Third, what meaning to assign to particular states of the designated inputs and outputs. Having explained these types of arbitrariness, we assess their relevance for (...) algorithms from various computational theories of mind (CTM) seeking to account for phenomenal consciousness. Some CTM accounts can survive some of these arbitrariness challenges, but eventually each one examined faces a trilemma. Each is under pressure to dilute at least one of three important CTM desiderata: its causal relevance, its substrate neutrality, or its assignment discrimination (e.g. ability to avoid near-panpsychism). However, unlike previous research, we suggest the debate cannot be fully settled at the level of principle. Certain complex CTM algorithms may be salvageable, albeit not the algorithms specified to date. The paper specifies three areas of investigative work, as well as further theoretical avenues of research, which computationalists may wish to explore to escape the trilemma. (shrink)

This unpublished paper from 2004 argues that the agenda for positive psychology laid out by Christopher Peterson and Martin Seligman in their massive work Character Strengths and Virtues: a Handbook and Classification (New York: Oxford University Press, 2004) might be improved by making several conceptual changes: 1) by developing general concepts of virtue (singular), and of positive health to clarify the relationships between specific virtues and competing conceptions of positive health; 2) by aligning the project more firmly with eudaimonistic accounts (...) of virtue that fit comfortably with scientific psychology; and 3) by aligning the project more firmly with the health sciences than with ethics and philosophy generally. The paper was developed from a talk prepared for the Working Conference on The Philosophical History of Character Strengths and Virtues, The University of Pennsylvania, September 2-4, 2004. (shrink)

It a mistake to think that opponents of the death penalty are invariably sentimentalists, motivated by tenderness to those convicted of deliberate murder. They might, quite rightly, often be motivated by compassion for others branded as criminals, who in more rational, more just, or kinder dispensations would not be criminals at all – for example, soliciting prostitutes and drug addicts. They might also understand, although (a different thing) neither condone nor forgive, murder committed in the unmeditated grip of passion. Such (...) attitudes are prompted by sympathy for the difficulties that can divert a life into making a hell for itself and others – or just for the frailties of the human spirit, so numerous and sometimes so final that they seem to be its destiny.

Libertarianism—and classical liberalism generally—entails (or presupposes) a specific, but implicit, conception of liberty. Imagine two lists of property-rights: one list is all those that currently appear to be libertarian (self-ownership, property acquired by use of natural resources, property acquired by consensual exchange, etc.); the other list is all those that currently appear not to be libertarian (aggressively imposed slavery, property acquired by theft or fraud, property acquired by coerced transfers due to welfare claims, etc.). What determines into which list a (...) property-right is to be assigned? If libertarianism is really about liberty, then the determining factor must be whether the property-right somehow fits what liberty is in a more abstract sense than property. It greatly clarifies matters to have an explicit theory of this entailed conception of abstract liberty and how it relates to its practical application and to morality. (shrink)

There are two major semantic theories of proper names: Semantic Descriptivism and Direct Reference. According to Semantic Descriptivism, the semantic content of a proper name N for a speaker S is identical to the semantic content of a definite description “the F” that the speaker associates with the name. According to Direct Reference, the semantic content of a proper name is identical to its referent. As is well known, Semantic Descriptivism suffers from a number of drawbacks first pointed out by (...) Donnellan (1970) and Kripke (1972).1 The first difficulty is semantic: in many cases, the definite description that S associates with N (if it denotes) denotes an entity other than the referent of N. The second difficulty is epistemic: in many cases, contrary to what Semantic Descriptivism predicts, an utterance of “N=the F” does not semantically express a proposition that is knowable a priori. And the third difficulty is modal: although Semantic Descriptivism entails that the proposition semantically expressed by an utterance of “N=the F” is metaphysically necessary, in many cases the relevant proposition is actually metaphysically contingent. Direct Reference faces three main difficulties of its own. First, there is the problem of cognitive significance (or, as it has come to be known, Frege’s Puzzle): if the content of a proper name is its referent, then different proper names have the same content, and hence utterances of “N=M” and “N=N” semantically express the same proposition; yet these two utterances differ in cognitive significance, and it would seem 1 that utterances semantically expressing the same proposition should not differ in cognitive significance. Second, there is the problem of substitution: if the content of a proper name is its referent, then co-referential proper names should be intersubstitutable in propositional attitude contexts salva veritate; yet linguistic intuitions suggest that substitution of co-referential proper names in such contexts often fails to preserve truthvalue..

When Professor Orr published his hostile review of Darwin's Dangerous Idea in the biology journal, Evolution, last February, I was not pleased. His review was full of falsehoods and misconstruals, but I had no recourse; that journal, like most academic journals, does not permit authors to respond to reviews. Luckily for me, Orr has been so eager to warn the world of my errors that he has restated his attack, with embellishments, in the Boston Review, which has invited me to (...) respond. Months have passed, the damage has been done, but at least I get to set the record straight. (shrink)

It is time to put to rest the mistakes and assumptions that lie behind a phrase used by some religious people when talking of those who are plain-spoken about their disbelief in any religious claims: the phrase "fundamentalist atheist". What would a non-fundamentalist atheist be?

Or that gods (...) exist only some of the time - say, Wednesdays and Saturdays? (That would not be so strange: for many unthinking quasi-theists, a god exists only on Sundays.) Or might it be that a non-fundamentalist atheist is one who does not mind that other people hold profoundly false and primitive beliefs about the universe, on the basis of which they have spent centuries mass-murdering other people who do not hold exactly the same false and primitive beliefs as themselves - and still do?

Nationalism is an evil. It causes wars, its roots lie in xenophobia and racism, it is a recent phenomenon – an invention of the last few centuries – which has been of immense service to demagogues and tyrants but to no-one else. Disguised as patriotism and love of one's country, it trades on the unreason of mass psychology to make a variety of horrors seem acceptable, even honourable. For example: if someone said to you, "I am going to send your (...) son to kill the boy next door" you would hotly protest. But only let him seduce you with "Queen and Country!" "The Fatherland!" "My country right or wrong!" and you would find yourself permitting him to send all our sons to kill not just the sons of other people, but other people indiscriminately – which is what bombs and bullets do.

All of inquiry is a mental process from the known to the unknown within the realm of possibility. This process uses the three faculties of perception, conception, and abstraction, all fueled by information. These faculties have corollaries in Science and Philosophy of Religion. It is the thesis of this book that if these faculties are intelligible and reliability in Science, there is no reason to reject them when used in other fields of inquiry.

The present issue is the beginning of a new journal from various sub-disciplines and paradigms in order – Cognitive Systems Research – which we have to construct a coherent picture of how the various developed in response to what we perceive to be an pieces fit together overall.

Half-lost in the now predictable August clamour about sex differences in examination results, renewed today by publication of the GCSE results, are old familiar clues, swirling neglected like scraps of paper in the storm around our heads.

This paper offers a "tu quoque" defense of strong AI, based on the argument that phenomena of self-consciousness and intentionality are nothing but the "negative space" drawn around the concrete phenomena of brain states and causally connected utterances and objects. Any machine that was capable of concretely implementing the positive phenomena would automatically inherit the negative space around these that we call self-consciousness and intention. Because this paper was written for a literary audience, some examples from Greek tragedy, noir fiction, (...) science fiction and Dada are deployed to illustrate the view. (shrink)

The present studies investigated children’s and adults’ intuitive beliefs about the physical nature of essences. Adults and children (ranging in age from 6 to 10 years old) were asked to reason about two different ways of determining an unknown object’s category: taking a tiny internal sample from any part of the object (distributed view of essence), or taking a sample from one specific region (localized view of essence). Results from three studies indicated that adults strongly endorsed the distributed view, and (...) children showed a developmental shift from a localized to distributed view with increasing age. These results suggest that even children go beyond mere placeholder notions of essence, committing to conceptual frameworks of how essences might be physically instantiated. (shrink)

We investigate how people use causal knowledge to design interventions to affect the outcomes of causal systems. We propose that in addition to using content or mechanism knowledge to evaluate the effectiveness of interventions, people are also influenced by the abstract structural properties of a causal system. In particular, we investigated two factors that influence whether people tend to intervene proximally (on the immediate cause of an outcome of interest) or distally (on the root cause of a chain leading to (...) the outcome). We presented people with causal chains describing a variety of real-world and artificial causal systems and asked them where they would intervene to affect the outcome. In Experiment 1, participants who were asked to choose the best long-term intervention intervened more distally than participants asked to choose the best short-term intervention. In Experiment 2, participants presented with a branching structure in which there were two distinct causal pathways from the root cause to the outcome were more likely to intervene on the root cause than participants presented with only one of the pathways. Our findings demonstrate two ways in which people integrate content knowledge and knowledge of a system’s causal structure to design effective interventions. (shrink)

Autism is a neurodevelopmental condition characterized by difficulties in social interaction. Successful social interaction relies, in part, on determining the thoughts and feelings of others, an ability commonly attributed to our faculty of folk or common-sense psychology. Because the symptoms of autism should be present by around the second birthday, it follows that the study of autism should tell us something about the early emerging mechanisms necessary for the development of an intact faculty of folk psychology. Our aims in this (...) chapter are threefold; to examine the literature on "socialunderstanding" mechanisms in autism, particularly those assumed to develop in the first years of life; to examine the related literature on typically developing infants and toddlers, and to examine the theoretical approaches that attempt to characterize the early stages and development of this impressive skill. In doing so, we hope to help resolve some of the disagreements and sticking points that riddle the topic. In particular we will attempt to shift the focus from whether children have this or that specific mental-state concept to a more developmentally friendly approach centered around the notion of reasons, recognizing that they may well exist before they are represented, and hence before they can be appreciated, or expressed. The peer commentary in Behavioral and Brain Sciences following Premack and Woodruff - "Does the chimpanzee have a theory of mind'" - not only introduced the "falsebelief' task, but addressed a host of issues surrounding the characterization of second-order intentional systems, systems that may be interpreted as having beliefs about beliefs (or desires or intentions...

What does it mean to talk of the power of God in relation to the human self? The discourses generated by the Jewish and Christian tradition about the capacity for divinity have been mainly promulgated by men, and have more often than not served to exclude women cognitively, practically, and spiritually. As a result they have been made powerless in the face of God’s presence. It is possible to look to ideas developed in Hindu Tantra for comparative notions of power (...) (shakti) which can redeem the place of God for women. The path of divine consciousness is effectively illustrated by an imaginary and somatic awareness, by a devout attention to the play of light in the soul. In this paper I propose to read the assignment of energy and force within conceptions of divinity through the lens of a poststructuralist realization, using the work of Michel Foucault, Gilles Deleuze and Félix Guattari, and Luce Irigaray. This working paper is basically an exercise in metaphorical writing, and one reader has called it 'creative theology'. (shrink)

La metafisica è quel ramo della filosofia che ha come oggetto la realtà considerata nei suoi aspetti più fondamentali e generali. L’origine del termine (letteralmente: ‘dopo’ o ‘oltre la fisica’) risale agli editori delle opere di Aristotele nel I secolo a.C., che lo usarono per classificare gli scritti dedicati a quest’argomento e ritenuti, appunto, posteriori a quelli dedicati alla fisica. L’essere si dice in molti modi, scriveva Aristotele in quelle pagine, e a questa molteplicità di significati corrispondono domini d’interesse specifici. (...) La matematica, per esempio, si occupa dell’essere sotto il profilo quantitativo, la fisica sotto il profilo naturale.

This paper, for two upcoming volumes, makes what I consider to be the definitive textual case for finally rejecting the phenomenalist interpretation of Ernst Mach's works, and his customary association with the Vienna Circle, in favor of a stronger realistic neutral monist reading connecting him to James, Russell and the American realist movement and today's neutral monism (for example my 2014).

I develop and defend a version of what I call Disposition-Based Decision Theory (or DBDT). I point out important problems in David Gauthier’s (1985, 1986) formulation of DBDT, and carefully develop a more defensible formulation. I then compare my version of DBDT to the currently most widely accepted decision theory, Causal Decision Theory (CDT). Traditional intuition-based arguments fail to give us any strong reason to prefer either theory over the other, but I propose an alternative strategy for resolving this debate. (...) I argue that we should embrace DBDT because it does better than CDT at the work that we, as a matter of empirical fact, commonly call upon a notion of rationality to do. (shrink)

How is it possible for a physical thing--a person, an animal, a robot--to extract knowledge of the world from perception and then exploit that knowledge in the guidance of successful action? That is a question with which philosophers have grappled for generations, but it could also be taken to be one of the defining questions of Artificial Intelligence. AI is, in large measure, philosophy. It is often directly concerned with instantly recognizable philosophical questions: What is mind? What is meaning? What (...) is reasoning, and rationality?

Clark and Karmiloff-Smith (CKS) have written an extraordinarily valuable paper, which sympathetically addresses what has all too often been an acrimonious and ideology-ridden "debate" and begins to transform it into a multi-perspective research program. By articulating the submerged hunches on both sides in a single framework, and adding some powerful new ideas of their own, they dispel much of the smoke of battle. What we can now see much more clearly is the need for a model of a brain/mind that, (...) as they say, "enriches itself from within by re-representing the knowledge that it has already represented.".

Back and forth swings the pendulum. It is remarkable that Baars can claim that “many scientists now feel that radical behaviorists tossed out the baby with the bathwater” while not being able to see that his own efforts threaten to be an instance of the complementary overshooting–what we might call covering a nice clean baby with dualistic dirt . Yes indeed, radical behaviorism of Skinner’s variety fell from grace some years ago, with the so-called cognitive revolution, to be replaced by (...) a sort of cognitivistic behaviorism that has plenty of room for inner processes, for talking to yourself, for mental imagery, for hunches, feelings, pains, dreams, beliefs and hopes and expectations, but only so long as these are understood to be physical (“informational” or “computational”) processes that could be accomplished by the machinery of the brain. It is an interesting speculative question whether William James would have been a wholehearted cognitivist, or whether he would have insisted that what he meant by the stream of consciousness had to be sharply distinguished from the streams of mere information-manipulation discernible in the activities of cortical subsystems, etc., etc. Making a home for consciousness in the brain, for a distinction between unconscious information-transformations and conscious ones, for instance, is now the work of many hands in many fields (See, e.g., Dennett, 2001, and the other essays in the special issue of Cognition devoted to the cognitive neuroscience of consciousness). The main methodological principle of this research is one shared with the radical behaviorists: only intersubjectively accessible data are to be admitted in this natural science of consciousness. If that allegiance, by itself , counts as ‘behaviorism,” then we should all be behaviorists, and indeed the very researchers Baars cites (Singer, Ericsson and Simon, Hilgard, Crick, and Edelman) scrupulously and unapologetically are behaviorists in this minimal sense. They interview their subjects, under controlled conditions, and take their reports seriously–but not as infallible guides to their subjects’ subjectivity.. (shrink)

Sometimes the way to make progress on a topic is to turn your back on it for a few years. At least I hope so, since I have just returned to the Frame Problem after several years of concentrating on other topics. It seems to me that I may have picked up a few odds and ends that shed light on the issues.
