Philosophy of Mind

Naturalism, Christianity, and the Human Person


What is the nature of the human person? A mere conglomeration of matter that consists of different levels of brain state or a being that is also endowed with a soul? In this final part of the series on Naturalism, Dr. J. P. Moreland exposes the philosophical inadequacies of physicalism and explains why the Christian message is more convincing.

Is the Human Person a Substance or a Property-thing?


In an era where the defence of human rights is prominent, a fundamental question is who counts as a human person and, more specifically, when does human personhood begin and end? The answer to the question at both ends of the spectrum requires metaphysical reflection in three areas: 1. What is a substance and what is a property-thing?; 2. What does it mean to be a human being?; and 3. What does it mean to be a human person? In this paper, we will address these questions in order to lay a metaphysical foundation for ethical decision-making concerning human rights at the edges of life. While the implications of this analysis extend to a variety of ethical issues, we will limit our application to the ontological status of the unborn, and argue that zygotes, embryos and fetuses (hereafter referred to synonymously) are fully and equally human beings, and consequently, human persons. We shall not address the abortion question directly, though we trust the implications of the arguments presented will become obvious.

David Chalmers on the Hard Problem of Consciousness


The really hard problem of consciousness is the problem of experience. When we think and perceive, there is a whir of information-processing, but there is also a subjective aspect. As Nagel (1974) has put it, there is something it is like to be a conscious organism. This subjective aspect is experience. When we see, for example, we experience visual sensations: the felt quality of redness, the experience of dark and light, the quality of depth in a visual field. Other experiences go along with perception in different modalities: the sound of a clarinet, the smell of mothballs. Then there are bodily sensations, from pains to orgasms; mental images that are conjured up internally; the felt quality of emotion, and the experience of a stream of conscious thought. What unites all of these states is that there is something it is like to be in them. All of them are states of experience…It is undeniable that some organisms are subjects of experience. But the question of how it is that these systems are subjects of experience is perplexing. Why is it that when our cognitive systems engage in visual and auditory information-processing, we have visual or auditory experience: the quality of deep blue, the sensation of middle C? How can we explain why there is something it is like to entertain a mental image, or to experience an emotion? It is widely agreed that experience arises from a physical basis, but we have no good explanation of why and how it so arises. Why should physical processing give rise to a rich inner life at all? It seems objectively unreasonable that it should, and yet it does. If any problem qualifies as the problem of consciousness, it is this one.

Francis Crick’s Astonishing Hypothesis


The Astonishing Hypothesis is that “You,” your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules.

Consciousness Reconsidered


This is one of the early philosophy books that started to make sense on the issue of consciousness. Comming from a decade where Joe Levine told us there was a gap, Frank Jackson that materialism left something out, McGuinn told us we could not understand it, the Churchlands wanted to get rid of the thing, this book is a great relief. Consciousness, according to Flanagan, is a natural phenomenon, rooted in the brain. It is real, capable of being defined, it evolved, and tractable scientifically. We need not despair, nor look in wrong and exotic places like quantum mechanics. Psychology, phenomenology, neurobiology and cognitive science will do. … This is good philosophy indeed. Consicousness is portrayed simply, as a natural phenomentol being understood through science. There are some objections one could make, but in all, considering the philosophical views of consicousness, this one is science friendly and informative. This is the kind of constructivism that one should expect from philosophers. ~ Carlos Camara at

David Papineau on Science and First Philosophy


At one level, the continuity of philosophy and empirical science is uncontentious. Many philosophical problems arise because of apparent tensions or conflicts within the assumptions which empirical evidence recommends to us. The most obvious examples are issues in the philosophy of science, such as problems about the interpretation of quantum mechanics, or the asymmetry of time, or the logic of natural selection. But other less specialist philosophical questions, like the existence of free will, also arise because of difficulties raised by empirical assumptions (in particular, in this case, by assumptions about the extent to which human beings are subject to the same laws of nature as the rest of the

John Searle on Naturalizing Content


So far no attempt at naturalizing content has produced an explanation (analysis, reduction) of intentional content that is even remotely plausible. A symptom that something is radically wrong with the project is that intentional notions are inherently normative. They set standards of truth, rationality, consistency, etc., and there is no way that these standards can be intrinsic to a system consisting entirely of brute, blind, nonintentional causal relations. There is no mean component to billiard ball causation. Darwinian biological attempts at naturalizing content try to avoid this problem by appealing to what they suppose is the inherently teleological, normative character of biological evolution. But this is a very deep mistake. There is nothing normative or teleological about Darwinian evolution. Indeed, Darwin’s major contribution was precisely to remove purpose, and teleology from evolution, and substitute for it purely natural forms.

A Review of Fontinell’s Self, God, and Immortality


This work is a technical monograph in pragmatist, process metaphysics. It seeks to answer this question: Given the inadequacies of materialism and classical dualism, can we still believe in personal immortality today? Fontinell answers with a tentative “yes” (in keeping with his pragmatism) by developing a doctrine of the self along Jamesian lines in two steps. Chapters 1-6 focus on the possibility of life after death, and chaps. 7-8 discuss the desirability of an afterlife.

Body, Soul and Life Everlasting


The book defends a functional integration of human life (body and soul are separate but dependent) on earth and in heaven but a disembodied intermediate state wherein the body and soul will be both separate and independent. Cooper’s research, objective and scrupulous, examines the widest spectrum: (1) Traditional Christian anthropology and its modern critics; (2) Old Testament anthropology’s holistic emphasis; (3) Old Testament anthropology’s dualistic implications; (4) The anthropology of intertestamental eschatology; (5) The monism-dualism debate about New Testament anthropology; (6) Anthropology and personal eschatology in the New Testament’s non-Pauline writings; (7) Anthropology and personal eschatology in the New Testament’s Pauline epistles; (8) New Testament eschatology and philosophical anthropology; (9) Practical and theological objections against dualism; (10) Holistic dualism, science, and philosophy; (11) And finally, a vindication of holistic dualism. ~ Blake G Edwards

An Enduring Self


It is well known that the various forms of process thought are agreed in denying the existence of an enduring self which maintains absolute identity through change.’ Process thought — regardless of whether time is taken to be continuous or discreet, or whether one holds to an A series or B series view of time — is committed to some form of ancestral chain model of the self wherein the self is a series of interrelated actual occasions in which earlier occasions are prehended by later members of the chain toform a serial nexus. There is no stable essence running through all members of the chain; the “persistent” self is a derived unification of momentary selves.

Richard Swinburne on Science and Secondary Qualities


There is a crucial difference between these two cases. All other integrations into a super-science, of sciences dealing with entities and properties apparently qualitatively very distinct, was achieved by saying that really some of the entities and properties were not as they appeared to be; by making a distinction between the underlying (not immediately observable) entities and properties and the phenomenal properties to which they give rise. Thermodynamics was conceived with the laws of temperature exchange; and temperature was supposed to be a property inherent in an object. The felt hotness of a hot body is indeed qualitatively distinct from particle velocities and collisions. The reduction was achieved by distinguishing between the underlying cause of the hotness (the motion of the molecules) and the sensations which the motion of molecules cause in observers. The former falls naturally within the scope of statistical mechanics — for molecules are particles; the entities and properties are not now of distinct kinds. But this reduction has been achieved at the price of separating off the phenomenal from its causes, and only explaining the latter.

Thomas Nagel on a Theory of Consciousness


What is needed is something we do not have: a theory of conscious organisms as physical systems composed of chemical elements and occupying space, which also have an individual perspective on the world, and in some cases a capacity for self-awareness as well. In some way that we do not now understand, our minds as well as our bodies come into being when these materials are suitably combined and organized. The strange truth seems to be that certain complex, biologically generated physical systems, of which each of us is an example, have rich nonphysical properties. An integrated theory of reality must account for this, and I believe that if and when it arrives, probably not for centuries, it will alter our conception of the universe as radically as anything has to date.

Daniel Dennet on the Illusion of Uncaused Acts


Whatever else we are, we are information-processing systems, and all information-processing systems rely on amplifiers of a sort. Relatively small causes are made to yield relatively large effects. … Vast amounts of information arrive on the coattails of negligible amounts of energy, and then, thanks to the amplification powers of systems of switches, the information begins to do some work — evoking other information that was stored long ago, for instance transmuting it for the present occasion in a million small ways, and leading eventually to an action whose pedigree of efficient (or triggering) causation is so hopelessly inscrutable as to be invisible. We see the dramatic effects leaving; we don’t see the causes entering; we are tempted by the hypothesis that there are no causes.

William Hasker on Computers as Extensions


Computers function as they do because they have been constructed by human beings endowed with rational insight. And the results of their computations are accepted because they are evaluated by rational human beings as conforming to rational norms. A computer, in other words, is merely an extension of the rationality of its designers and users, it is no more an independent source of rational insight than a television set is an independent source of news and entertainment.

Roy Batty on Death and Meaning


I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I watched c-beams … glitter in the dark near Tanhauser Gate. All those … moments will be lost … in time, like tears … in rain. Time … to die.

C.S. Lewis on Biology, Theism, and Reason


Once, then, our thoughts were not rational. That is, all our thoughts once were, as many of our thoughts still are, merely subjective events, not apprehensions of objective truth. Those which had a cause external to ourselves at all were (like our pains) responses to stimuli. Now natural selection could operate only by eliminating responses that were biologically hurtful and multiplying those which tended to survival. But it is not conceivable that any improvement of responses could ever turn them into acts of insight, or even remotely tend to do so. The relation between response and stimulus is utterly different from that between knowledge and the truth known. Our physical vision is a far more useful response to light than that of the cruder organisms which have only a photo-sensitive spot. But neither this improvement nor any possible improvements we can suppose could bring it an inch nearer to being a knowledge of light. It is admittedly something without which we could not have had that knowledge. But the knowledge is achieved by experiments and inferences from them, not by refinement of the response. It is not men with specially good eyes who know about light, but men who have studied the relevant sciences. In the same way our psychological responses to our environment — our curiosities, aversions, delights, expectations — could be indefinitely improved (from the biological point of view) without becoming anything more than responses. Such perfection of the non-rational responses, far from amounting to their conversion into valid inferences, might be conceived as a different method of achieving survival — an alternative to reason. A conditioning which secured that we never felt delight except in the useful nor aversion save from the dangerous, and that the degrees of both were exquisitely proportional to the degree of real utility or danger in the object, might serve us as well as reason or in some circumstances better.

Raymond A. Moody, Jr. on Near Death Experiences

Go Despite the wide variation in the circumstances surrounding close calls with death and in the types of persons undergoing them, it remains true that there b a striking similarity among the accounts of the experiences themselves. In fact the similarities among various reports are so great that one can easily pick out about fifteen separate elements which recur again and again in the mass of narrative that I have collected. On the basis of these points of likeness, let me now construe a brief, theoretically "ideal" or "complete" experience which embodies all of the common elements, in the order in which it is typical for them to occur. ¶ A man is dying and, as he reaches the point of greatest physical distress, he hears himself pronounced dead by his doctor. He begins to hear an uncomfortable noise, a low ringing or buzzing, and at the same time feels himself moving very rapidly through a long dark tunnel. After this, he suddenly finds himself outside of his own physical body, but still in the immediate physical environment, and he sees his own body from a distance, as though he is a spectator. He watches the resuscitation attempt from this unusual vantage point and is in a state of emotional upheaval. ¶ After a while, he collects himself and becomes more accustomed to his odd condition. He notices that he still has a "body," but one of a very different nature and with very different powers from the physical body he has left behind. Soon other things begin to happen. Others come to meet and to help him. He glimpses the spirits of relatives and friends who have already died, and a loving, warm spirit of a kind he has never encountered before — a being of light — appears before him. This being asks him a question, nonverbally, to make him evaluate his life and helps him along by showing him a panoramic, instantaneous playback of the major events of his life. At some point he finds himself approaching some sort of barrier or border, apparently representing the limit between earthly life and the next life. Yet, he finds that he must go back to the earth, that the time for his death has not yet come. At this point he resists, for by now he is taken up with his experiences.

Gottfried Leibniz on Perceiving Machines


It must be confessed, moreover, that perception, and that which depends on it are inexplicable by mechanical causes, that is, by figures and motions. And, supposing there were a machine so constructed as to think, feel and have perception, we could conceive of it as enlarged and yet preserving the same proportions, so that we ight enter it as a mill. And this granted, we should only find on visiting it, pieces which push one against another, but never anything by which to explain a perception. This must be sought for, therefore, in the simple substance and not in the composite or in the machine.

William Lyons on Evolution as a Seamless Garment

Go Physicalism] seem[s] to be in tune with the scientific materialism of the twentieth century because it [is] a harmonic of the general theme that all there is in the universe is matter and energy and motion and that humans are a product of the evolution of species just as much as buffaloes and beavers are. Evolution is a seamless garment with no holes wherein souls might be inserted from above.

Bede Rundle on the Irreducible Qualities of Beliefs

Go The idea that an ultimate source of being and becoming is to be found in the purely mental and non-physical is at odds with the conception of mind espoused by most contemporary philosophers. It is commonly held that mental states are to be characterized in terms of their causal role, but since such states are thought to be states of the brain, there is no lessening of a dependence on the physical. This is not a position I wish to invoke. It is doubtless true that we could not believe, desire, or intend without a brain, but any attempt to construe belief and the rest as states of that organ involves a serious mismatch between the psychological concepts and physical reality. Beliefs can be obsessive, unwavering, irrational, or unfounded, but nothing inside anyone's head answers to such descriptions.

C. S. Lewis on Personifying Trees and People

Go The process whereby man has come to know the universe is from one point of view extremely complicated; from another it is alarmingly simple. We can observe a single one-way progression. At the outset, the universe appears packed with will, intelligence, life, and positive qualities; every tree is a nymph and every planet a god. Man himself is akin to the gods. The advance gradually empties this rich and genial universe, first of its gods, then of it colours, smells, sounds and tastes, finally of solidity itself as solidity was originally imagined. As these items are taken from the world, they are transferred to the subjective side of the account: classified as our sensations, thoughts, images or emotions. The Subject becomes gorged, inflated, at the expense of the Object. But the matter does not rest there. The same method which has emptied the world now proceeds to empty ourselves. The masters of the method soon announce that we were just mistaken (and mistaken in much the same way) when we attributed "souls" or "selves" or "minds" to human organisms, as when we attributed Dryads to the trees. Animism, apparently, begins at home. We, who have personified all other things, turn out to be ourselves mere personifications. Man is indeed akin to the gods, that is, he is no less phantasmal than they. Just as the Dryad is a "ghost," an abbreviated symbol for certain verifiable facts about his behaviour: a symbol mistaken for a thing. And just as we have been broken of our bad habit of personifying tees, so we must now be broken of our habit of personifying men; a reform already effected in the political field. There never was a Subjective account into which we could transfer the items which the Subject had lost. There is no "consciousness" to contain, as images or private experiences, all the lost gods, colours, and concepts. Consciousness is "not the sort of noun that can be used that way."

Frank Jackson on Intuition Going Wrong

Go Much of the contemporary debate in the philosophy of mind is concerned with the clash between certain strongly held intuitions and what science tells us about the mind and its relation to the world. What science tells us about the mind points strongly towards some version or other of physicalism. The intuitions, in one way or another, suggest that there is something seriously incomplete about any purely physical story about the mind. For our purposes here, we can be vague about the detail and think broadly of physicalism as the view that the mind is a purely physical part of a purely physical world. Exactly how to delineate the physical will not be crucial: anything of a kind that plays a central role in physics, chemistry, biology, neuroscience and the like, along with the a priori associated functional and relational properties count as far as we are concerned. Most contemporary philosophers given a choice between going with science and going with intuitions, go with science. Although I once dissented from the majority, I have capitulated and now see the interesting issue as being where the arguments from the intuitions against physicalism — the arguments that seem so compelling — go wrong. For some time, I have thought that the case for physicalism is sufficiently strong that we can be confident that the arguments from the intuitions go wrong somewhere, but where is somewhere?

In Defence of the Soul

Go Countering denials of the existence of the soul with a detailed examination of philosophical, anthropological, and scientific attacks on God, Professor Ward presents a convincing case for the role of human soul in the modern world. Denying the existence of the soul has devastating effects on our valuation of human beings maintains Ward in this closely argued book. He examines a diversity of philosophical, anthropological and scientific attacks on God and the reality of the human soul. Taking current scientific arguments back to their essentials, he presents a convincing case. Ward is one of Britain's foremost writers on comparative religion and Christian issues. ~ Product Description

Objects and Persons

Go With ontology motivated largely by causal considerations, this lucid and provocative work focuses on the idea that physical objects are causally non-redundant. Merricks "eliminates" inanimate composite macrophysical objects on the grounds that they would — if they existed — be at best completely causally redundant. He defends human existence by arguing, from certain facts about mental causation, that we cause things that are not determined by our proper parts. He also provides insight into a variety of philosophical puzzles, while addressing many significant issues like free will, the "reduction" of a composite object to its parts, and the ways in which identity over time can "for practical purposes" be a matter of convention. Anyone working in metaphysics will enjoy this book immensely. ~ Book Description
