Perception is often analysed as a process in which causal events from the environment act on a subject to produce states in the mind or brain. The role of the subject is an increasing feature of neuroscientific and cognitive literature. This feature is linked to the need for an account of the normative aspects of perceptual competence. A holographic model is offered in which objects are presented to the subject classified according to rules governing concepts and encoded in brain function in that form. This implies that the analysis of perception must consider not only the fact that there is an interaction between the perceiving subject and the perceived object but also that the interaction is shaped by a system of concepts which the subject uses in thought and action.

Abstract The phenomenology of Multiple Personality (MP) syndrome is used to derive an Aristotelian explanation of the failure to achieve rational integration of mental content. An MP subject is best understood as having failed to master the techniques of integrating conative and cognitive aspects of her mental life. This suggests that in irrationality the subject may lack similar skills basic to the proper articulation and use of mental content in belief formation and control of action. The view that emerges centres mind on the activity of a subject rather than a structured causal nexus

Abstract The language of consciousness and that of brain function seem vastly different and incommensurable ways of approaching human mental life. If we look at what we mean by consciousness we find that it has a great deal to do with the sensitivity and responsiveness shown by a subject toward things that happen. Philosophically, we can understnd ascriptions of consciousness best by looking at the conditions which make it true for thinkers who share the concept to say that one of them is conscious. This depends on consciousness being manifest. When we also note that manifest, flexible and exploratory responses to one's environment are the basis of concept use, an a priori link between concepts and consciousness is forged. The brain structures subserving such responses are complex but crucially involve the multi?tracked and cross?linked information processing to be found in the neocortex. This function draws on the motivational and orienting activity arising in lower brain systems but orchestrates that into an articulated structure of behaviour control. The conclusion is that human consciousness is an umbrella term for complex and animated mental activity which makes extensive use of many different perceptual systems and also of the social milieu within which human cognition develops

Abstract Experience is structured by thoughts which are composed of general concepts and conceptions of objects. Both of these elements of thought are rule?governed and rest on norms which are shared by thinkers. Concepts and conceptions of objects as the elements of thoughts whose content is essentially communicable plausibly rest on abilities tied to the use of linguistic terms. This suggests that language plays an active part in structuring human experience and cognition as suggested by both Vygotsky and Luria. The role of language in thought implies that the human brain which is the information processing structure realizing thoughts is itself subject to shaping by the social milieu. Neural network theory suggests that this might proceed via the use of cue stimuli based on the responses of other human beings and, therefore, supports the view that cognitive neuroscience may be radically mistaken in thinking that it can provide an individualistic analysis of human mental life

The Snark is an intentional object. I examine the general philosophical characteristics of thoughts of objects from the perspective of Husserl’s, hyle, noesis, and noema and show how this meets constraints of opacity, normativity, and possible existence as generated by a sensitive theory of intentionality. Husserl introduces terms which indicate the normative features of intentional content and attempts to forge a direct relationship between the norms he generates and the actual world object which a thought intends. I then attempt to relate Husserl’s account to Fregean insights about the sense and reference of a term. Neither Husserl nor Frege suggest plausible routes to a naturalistic account of intentionality and I turn to Wittgenstein to provide a naturalistic reading of the crucial terms involved in the analysis of intentional content. His account is normative in a way required by both Husserl and Frege and yet manages a kind of Aristotelian naturalism which avoids crude biologism.

Cara sui (care of the self) is a guiding thread in Foucault's later writings on ethics. Following Foucault in that inquiry, we are urged beyond our fairly superficial conceptions of consequences, harms, benefits, and the rights of persons, and led to examine ourselves and try to articulate the sense of life that animates ethical reasoning. The result is a nuanced understanding with links to virtue ethics and post-modern approaches to ethics and subjectivity. The approach I have articulated draws on the phenomenology of Levinas and Heidegger, the Virtue ethics of Baier, and the post-structuralist writing of Michel Foucault. The subject is seen as negotiable, embodied, provisional and able to be transformed in a way that denies essentialism about human beings, their moral status, and the idea of the good. The human being emerges as responsible because, properly, responsive to the context of discourse in which morality becomes articulated. When we import this style of thinking into bioethics we find that it reaches beyond issues of policy or right conduct and allows us to use the biomedical sciences and the clinical world to revise and interrogate our understanding of ourselves and the theoretical foundations of health care ethics.

Free will seems to be part of the romantic echo of a world view which predates scientific psychology and, in particular, cognitive neuroscience. Findings in cognitive neuroscience seem to indicate that some form of physicalist determinism about human behavior is correct. However, when we look more closely we find that physical determinism based on the view that brain events cause mental events is problematic and that the data which are taken to support that view, do nothing of the kind. In fact that view meets some substantial objections which turn on the role of the contents of our thoughts and experiences in explaining our behavior. When we look at mental or psychological content we find it is governed by rules and not just causal laws. Rule-following is an activity which invokes the role of the thinker as rational agent and this is not a causal type of explanation. The fact that the thinker as agent is important means that when we invoke the way that a subject thinks about the world, we conceive of that subject as located in a socio–cultural context. This in turn requires that we recognize an explanatory circle according to which neither brain science nor social science can claim priority in explaining human behavior and it follows that, for the purposes of psychological explanation and the understanding of the brain as an organ subserving a system of representation, we are bound to regard human beings as reasoning beings who exert some control over their own behavior and not just as physical systems. This defeats the causal determinist position

Transcultural dialogue and research are often bedeviled by a range of divergences in the use and resonances of key terms defining the focus of the conversation; social understandings; ways of dealing with the life situations involved; and traditional protocols in relation to the ethical challenges in the areas of research. A simple example from research into genetics will illustrate the problem. A team from two New Zealand universities comprising both Māori and NZ European academics examined indigenous attitudes to genetic technologies. A breakdown of trust became evident such that many of the Māori members of the team felt they could no longer participate because they felt their views...

The psychopathic personality disorder historically has been thought to include an insensitivity to morality. Some have thought that the psychopath's insensitivity indicates that he does not understand morality, but the relationship between the psychopath's defects and moral understanding has been unclear. We attempt to clarify this relationship, first by arguing that moral understanding is incomplete without concern for morality, and second, by showing that the psychopath demonstrates defects in frontal lobe activity which indicate impaired attention and adaptation to environmental conditions which are relevant to the formation of complex intentions. We argue that these frontal lobe defects can help to explain both the psychopath's apparent insensitivity to morality and his characteristic imprudence.

The two commentators have examined and illuminated different aspects of the analysis of delusions that we have offered. Their discussions both raise points that clarify that analysis in helpful ways. Richard Bentall (2014) makes the telling point that distinguishing the mental phenomena that count as delusions is not always straightforward and that, at the margins, there is a perennial problem with patterns of thought that seem to fall outside the realm of shared meanings that most of us derive from our experiences. The problem is evident in certain marginal conditions that come to psychiatric attention, like conversion reactions, body dysmorphic disorder, anorexia, and the many obsessions or strained ..

Delusions, a key feature of psychosis, are usually thought of as a type of belief, as in the definition of the American Psychiatric Association: A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person’s culture or subculture (e.g. it is not an article of religious faith). This characterization is often criticized, but other definitions typically comprise similar elements. For some, delusions are only loosely considered as beliefs (Jaspers 1963; Moor and Tucker ..

The concept of futility is sometimes regarded as a cloak for medical paternalism in that it rolls together medical and value judgments. Often, despite attempts to disambiguate the concept, that is true and it can be applied in such a way as to marginalize the real interests of a patient. I suggest we replace it with a conceptual toolkit that includes physiological futility, substantial benefit (SB), and the risk of unacceptable badness (RUB) in that these concepts allow us to articulate what is at stake in ethical judgments where outcomes are crucial in determining what should be done

We view a human being as a mental and spiritual entity and also as having a physical nature. The essence of a person is revealed in our thinking about personal identity, quality of life, and personal responsibility. These conceptions do not fare well in a Cartesian or dualist picture of the person as there are deep problems with the idea that the mind is an inner realm. I argue that it is only as we see the thoughts, actions, and interactions of persons as necessarily involving physical entities in the world whose nature is not completely captured in scientific descriptions that we can understand our existence as mental and spiritual beings.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.2 (2002) 123-125 [Access article in PDF] The Self as Relatum in Life and Language Grant Gillett THE STUDY REPORTED by van Staden is extremely interesting to any psychological theorist influenced by Jacques Lacan because of Lacan's insistence that the unconscious is not only structured like a language but actually reflects and is produced by linguistic interactions between the subject and others.The distinction he draws, on the basis of Frege's analysis of logical and grammatical structure, is not straightforwardly evident on a superficial inspection of the sentences concerned. It is also less clear than the agent-patient or subject-object distinction that one might look for on the basis of considering the action being performed. van Staden makes both of these points in the course of illustrating the relevant deep grammatical property on which the study turns. In doing so he engages with the subtle work on subject and object by Strawson (1959) who was one of the first, in the "descriptive metaphysics" of Individuals, to explore the resonance between what we might call (after Frege) "logical grammar" and the deep metaphysical structure of our thought. Strawson noted that the position of grammatical subject in a sentence was typically occupied by a particular or individual substance rather than the accident or property of a substance so that the subject predicate structure of language reflects a basic feature of our world picture whereby the world is seen to be populated by particular objects that instance universal features.Chomsky is the other player whose thought is important in this area in that he argues that we have an innate sense of deep structure, which allows us to disambiguate any sentence so as to reveal the state of affairs that is being represented. Thus we discern that what is denoted by "John loves Mary" is the same thought as that conveyed by "Mary is loved by John." van Staden focuses on something more general—the deep structure that expresses semantic relations or positions. This is not the same as the agent or the simply grammatical subject and van Staden calls it the owner of the relation involved as distinct from the accident of that relation. The terms are well chosen because ownership is a term a la mode in postmodern thought to express the relationship of a human being to the events and attributes associated with him or her. When we look at this subtle grammatological or semantic feature of language we see that the linguistic feature in question is the kind of thing that could easily be overlooked were it not for a post-Fregean analysis of the type van Staden offers.The content that van Staden identifies in relation to what is signified or represented by an utterance is difficult to characterize. It is not what Frege would call logical content in that it does not contribute to the truth value of any of the propositions concerned. It is also problematic to call it psychological content because it is not part of the conscious message conveyed by the utterance. Nevertheless, the study concerned raises [End Page 123] the possibility that it is psychic in a very significant way, which is best approached by considering the relationships between language and the unconscious.Chomsky is regarded as having defined a number of linguistic operations that take propositional or meaningful content and transform it into the form in which it is uttered. The relevant cognitive operations are usually regarded as being performed by the cognitive unconscious, which in some sense applies the rules of grammar to yield well-formed utterances on the basis of speaker intentions. In any event, nobody would seriously question the idea that there are unconscious operations that underpin the production of grammatically structured utterances.If we add to this the possibility that a more dynamic aspect to the unconscious has a role to play in the semantic content of our utterances, then a fruitful line of thought begins to emerge. The dynamic unconscious has to do with self-image and those influences that form the psyche...

This book uses a neo-Aristotelian framework to examine human subjectivity as an embodied being. It examines the varieties of reductionism that affect philosophical writing about human origins and identity, and explores the nature of rational subjectivity as emergent from our neurobiological constitution. This allows a consideration of the effect of neurological interventions such as psychosurgery, neuroimplantation, and the promise of cyborgs on the image of the human. It then examines multiple personality disorder and its implications for narrative theories of the self, and explores the idea of human spirituality as an essential aspect of embodied human subjectivity.
