Topics on the bordergrounds of action∗

The psychological conceptualization of phenomena involves characteristic explanations of animal movement. Conscientious attention to this fact results in a kind of behaviorism I call ‘conceptual epiphenomenalism’. This doctrine at once explains the characteristic ‘opacity’ of psychological predicables and helps to show the way around difficulties opacity is felt to create, and it also frees our thinking from the tyranny of the distinction between necessity and contingency, too often misapplied to facts rather than to things said or thought. An important challenge to conceptual epiphenomenalism is to account for the facts of introspective certainty and privileged testimony. This challenge can be met by identifying the nature of and displaying the behavioral conditions for the various grades of self‐consciousness or reflective knowledge. The methodology of conceptual epiphenomenalism is schematically applied to elucidate first the general conception of animal action and then a variety of phenomena plausibly thought to be exponible by reference to the conception of action, specifically the broader category of animal behavior, intention, and hoping and wishing.     

Property Dualism,Epistemic Normativity and the Limits of Naturalism*

This paper examines some consequences of the (quasi‐)epiphenomenalism implied by a property dualistic view of phenomenal consciousness. The focus is upon the variation of phenomenal content over time. A thought‐experiment is constructed to support two claims. The weaker claim exhibits an incompatibility which arises in certain logically possible situations between a conscious subject’s epistemic norms and the requirement that one be aware of one’s conscious experience. This could be interpreted as providing some epistemic grounds for the postulation of bridging laws between the physical/functional and phenomenal domains. The stronger claim has it that the ontology of property dualism is not properly able to account for the certainty I have of being phenomenally conscious. The problem is viewed as resulting from the neglect of the intensional context involved in a proper representation of the argument for property dualism. It is argued that only a transcendental move can do justice to this certainty I have.     

MORALITY AND NATURE: EVOLUTIONARY CHALLENGES TO CHRISTIAN ETHICS

Christian ethics accentuates in manifold ways the unique character of human nature. Personalists believe that the mind is never reducible to material and physical substance. The human person is presented as the supreme principle, based on arguments referring to free‐willed actions, the immateriality of both the divine spirit and the reflexive capacity, intersubjectivity and self‐consciousness. But since Darwin, evolutionary biology slowly instructs us that morality roots in dispositions that are programmed by evolution into our nature. Historically, Thomas Huxley, “Darwin's bulldog,” agreed with Darwin on almost everything, except for his gradualist position on moral behavior. Huxley's “saltationism” has recently been characterized by Frans de Waal as “a veneer theory of morality.” Does this mark the end of a period of presenting morality as only the fruit of socialization processes (nurture) and as having nothing in common with nature? Does it necessarily imply a corrosion of personalist views on the human being or do Christian ethics have to become familiar again with their ancient roots?     

Consciousness and Self in Animals: Some Reflections

In this essay I argue that many nonhuman animal beings are conscious and have some sense of self. Rather than ask whether they are conscious, I adopt an evolutionary perspective and ask why consciousness and a sense of self evolved—what are they good for? Comparative studies of animal cognition, ethological investigations that explore what it is like to be a certain animal, are useful for answering this question. Charles Darwin argued that the differences in cognitive abilities and emotions among animals are differences in degree rather than differences in kind, and his view cautions against the unyielding claim that humans, and perhaps other great apes and cetaceans, are the only species in which a sense of self‐awareness has evolved. I conclude that there are degrees of consciousness and self among animals and that it is likely that no animal has the same highly developed sense of self as that displayed by most humans. Many animals have a sense of “body‐ness” or “mine‐ness” but not a sense of “I‐ness.” Darwin's ideas about evolutionary continuity, together with empirical data (“science sense”) and common sense, will help us learn more about consciousness and self in animals. Answers to challenging questions about animal self‐awareness have wide‐ranging significance, because they are often used as the litmus test for determining and defending the sorts of treatments to which animals can be morally subjected.     

Willusionism,epiphenomenalism, and the feeling of conscious will

While epiphenomenalism—i.e., the claim that the mental is a causally otiose byproduct of physical processes that does not itself cause anything—is hardly ever mentioned in philosophical discussions of free will, it has recently come to play a crucial role in the scientific attack on free will led by neuroscientists and psychologists. This paper is concerned with the connection between epiphenomenalism and the claim that free will is an illusion, in particular with the connection between epiphenomenalism and willusionism, i.e., with the thesis that there is empirical evidence for a thoroughgoing skepticism with regard to free will that is based on the claim that mental states are epiphenomena. The paper discusses four arguments for willusionism that in some form or other appeal to epiphenomenalism and argues that three of them can be discarded relatively easily. The fourth one, based on Daniel Wegner’s theory of apparent mental causation and his claim that free will is an illusion because the feeling of conscious will is epiphenomenal with regard to the corresponding voluntary actions, is dealt with in more detail. The overall verdict is negative: there is no empirical evidence for any kind of epiphenomenalism that would warrant the claim that free will is an illusion. Whatever it is that makes free will the object of contention between neuroscience and philosophy, epiphenomenalism provides no reason to think that free will is an illusion.     

SENSATION,INTENTIONALITY, AND ANIMAL CONSCIOUSNESS: MALEBRANCHE'S THEORY OF THE MIND

In general, seventeenth-century philosophers seem to have assumed that intentionality is an essential characteristic of our mental life. Malebranche is perhaps the only philosopher in the period who stands out clearly against the prevailing orthodoxy; he is committed to the thesis that there is a large class of mental items - sensations - which have no representational content. In this paper I argue that due attention to this fact makes it possible to mount at least a partial defence of his notorious doctrine of ‘the rainbow-coloured soul’; Malebranche's doctrine is a striking anticipation of modern adverbial theories of sensation. I then argue that failure to appreciate the non-intentional character of sensations for Malebranche vitiates one recent attempt to explain why he accepted the Cartesian doctrine of the beastmachine; in contrast to the Radners, I suggest that Malebranche has the philosophical resources to offer an interesting theory of animal consciousness, and that his failure to develop such a theory rests largely on his acceptance of certain theological arguments. The paper ends by speculating about how Malebranche's theological commitments may have encouraged him to adopt the philosophically important thesis that intentionality is not the mark of the mental.     

Treating animals as ends

Conclusion Starting with a moral theory famous for being antagonistic toward animal rights, I have argued that we do have direct duties toward some animals, specifically those animals most closely related to human beings, whose behavior is reasonably interpreted as the result of conscious choice. Like animal rights views, the Kantian view escapes the intuitive counter-examples leveled at simple versions of utilitarianism. It rules out causing pain to the protected animals and also rules out killing them painlessly. But the Kantian view does not rule out painless experimentation at the cost of ruling out even harmless observation of animals. Nor is it restricted to a doctrine of negative obligations. The Kantian view forbids actions we intuitively think are wrong, allows those we think are permissible, and enjoins those we think are praiseworthy.     

Animals,humans and x-men: Human uniqueness and the meaning of personhood

Research in animal intelligence suggests to some that humans are different only in degree from animals, possibly eroding the traditional theological doctrine of the imago dei. In this paper, several critical boundary areas between humans and animals are examined for scientific evidence about human distinctiveness. These include communication and language capacity, cultural creativity, spirituality, and ethical capacity. Chimpanzee language studies and research in Neanderthal mentality are examined as the closest known natural approximations to human communication and intelligence. The implications of the findings are explored in relation to human culture, ethics, and spirituality in a context consistent with evolutionary continuity. Aspects of human uniqueness are apparent, can be fruitfully encompassed in the idea of personhood, and are coherent with Trinitarian theology's anthropological focus.     

Husserl,Phenomenology, and Foundationalism

Husserl is often taken, and not without reason, to endorse the view that phenomenology's task is to provide the “absolute foundation” of human knowledge. In this paper, I will argue that the most natural interpretation of this view, namely that all human knowledge depends for its justification, at least in part, on phenomenological knowledge, is philosophically untenable. I will also present evidence that Husserl himself held no such view, and will argue that Dan Zahavi and John Drummond, though reaching the same conclusion, reach it for the wrong reasons. In the process, I will also defend a brand of epistemological externalism according to which knowledge does not depend upon knowing the epistemic principles under which one's knowledge falls, and argue that Husserl himself held such a view. I conclude with a discussion of a few of the ways in which phenomenology positively contributes to human knowledge.     

Consciousness, accessibility, and the mesh between psychology and neuroscience

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We see the problem in stark form if we ask how we can tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: Find the neural natural kinds that are the basis of phenomenal consciousness in clear cases--when subjects are completely confident and we have no reason to doubt their authority--and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: Do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is "Yes," then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is "Yes"? The suggested methodology requires an answer to the question it was supposed to answer! This target article argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. I argue that we can find a neural realizer of this overflow if we assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified (other things being equal) by the explanations it allows.     

EXPLANATORY EPIPHENOMENALISM

I propose a new form of epiphenomenalism, 'explanatory epiphenomenalism', the view that the identification of A's mental properties does not provide a causal explanation of A's behaviour. I arrive at this view by showing that although anomalous monism does not entail type epiphenomenalism (despite what many of Davidson's critics have suggested), it does (when coupled with some additional claims) lead to the conclusion that the identification of A's reasons does not causally explain A's behaviour. I then formalize this view and show that it is an attractive position, because it captures the insights of existing forms of epiphenomenalism without their onerous metaphysical commitments.     

Phenomenal consciousness, attention and accessibility

This article re-examines Ned Block??s (1997, 2007) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block??s claim that phenomenology and accessibility have different neural substrates is highly problematic in light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness.     

Pre-reflective self-as-subject from experiential and empirical perspectives

In the first part of this paper I characterize a minimal form of self-consciousness, namely pre-reflective self-consciousness. It is a constant structural feature of conscious experience, and corresponds to the consciousness of the self-as-subject that is not taken as an intentional object. In the second part, I argue that contemporary cognitive neuroscience has by and large missed this fundamental form of self-consciousness in its investigation of various forms of self-experience. In the third part, I exemplify how the notion of pre-reflective self-awareness can be of relevance for empirical research. In particular, I propose to interpret processes of sensorimotor integration in light of the phenomenological approach that allows the definition of pre-reflective self-consciousness.     

Hylemorphism,remnant persons and personhood

Animalism is the doctrine that we human beings are – are identical with – animals. Hylemorphism is a form of animalism. In this paper, I defend hylemorphism by showing that while other forms of animalism fall prey to the problem of ‘Remnant Persons,’ hylemorphism does not. But hylemorphism's account of personhood seems to have some very implausible implications. I address one of those implications, and argue that it isn't nearly as objectionable as it might at first appear.     

Consciousness and Criterion: On Block's Case for Unconscious Seeing

Block ( 2012 ) highlights two experimental studies of neglect patients which, he contends, provide ‘dramatic evidence’ for unconscious seeing. In Block's hands this is the highly non‐trivial thesis that seeing of the same fundamental kind as ordinary conscious seeing can occur outside of phenomenal consciousness. Block's case for it provides an excellent opportunity to consider a large body of research on clinical syndromes widely held to evidence unconscious perception. I begin by considering in detail the two studies of neglect to which Block appeals. I show why their interpretation as evidence of unconscious seeing faces a series of local difficulties. I then explain how, even bracketing these issues, a long‐standing but overlooked problem concerning our criterion for consciousness problematizes the appeal to both studies. I explain why this problem is especially pressing for Block given his view that phenomenal consciousness overflows access consciousness. I further show that it is epidemic—not only affecting all report‐based studies of unconscious seeing in neglect, but also analogous studies of the condition most often alleged to show unconscious seeing, namely blindsight.     

Leibniz on Memory and Consciousness

In this article, I develop a higher-order interpretation of Leibniz's theory of consciousness according to which memory is constitutive of consciousness. I offer an account of Leibniz's theory of memory on which his theory of consciousness may be based, and I then show that Leibniz could have developed a coherent higher-order account. However, it is not clear whether Leibniz held (or should have held) such an account of consciousness; I sketch an alternative that has at least as many advantages as the higher-order theory. This analysis provides an important antecedent to the contemporary discussions of higher-order theories of consciousness.     

New evidence of animal consciousness

This paper reviews evidence that increases the probability that many animals experience at least simple levels of consciousness. First, the search for neural correlates of consciousness has not found any consciousness-producing structure or process that is limited to human brains. Second, appropriate responses to novel challenges for which the animal has not been prepared by genetic programming or previous experience provide suggestive evidence of animal consciousness because such versatility is most effectively organized by conscious thinking. For example, certain types of classical conditioning require awareness of the learned contingency in human subjects, suggesting comparable awareness in similarly conditioned animals. Other significant examples of versatile behavior suggestive of conscious thinking are scrub jays that exhibit all the objective attributes of episodic memory, evidence that monkeys sometimes know what they know, creative tool-making by crows, and recent interpretation of goal-directed behavior of rats as requiring simple nonreflexive consciousness. Third, animal communication often reports subjective experiences. Apes have demonstrated increased ability to use gestures or keyboard symbols to make requests and answer questions; and parrots have refined their ability to use the imitation of human words to ask for things they want and answer moderately complex questions. New data have demonstrated increased flexibility in the gestural communication of swarming honey bees that leads to vitally important group decisions as to which cavity a swarm should select as its new home. Although no single piece of evidence provides absolute proof of consciousness, this accumulation of strongly suggestive evidence increases significantly the likelihood that some animals experience at least simple conscious thoughts and feelings. The next challenge for cognitive ethologists is to investigate for particular animals the content of their awareness and what life is actually like, for them.Donald R. Griffin died on 7 November 2003
