The question, “Does the chimpanzee have a theory of mind?” is logically identical to the question, “Does the chimpanzee have a soul?” It is a peculiarity of our culture that we talk about anyone having a mind, and such talk is unhelpful for a science of behavior. The label “killjoy hypothesis” is an ad hominem attack.

The argument of this paper is that the modern brain-consciousness debate has left out one important element: the question of a transpersonal or spirit-like element of consciousness. Thus the problem really is not a mind-body-problem or brain-consciousness problem, but a mind-body-spirit or brain-consciousness-soul problem. Looking at the history of the debate it can be seen that, explicitly or implicitly, this aspect has always been part of the philosophical debate. Most notably, this can be seen in the Aristotelian concept of the soul, which held that form and matter were both together necessary to constitute a unity. But on top of that, a Platonic strand of teaching existed in Aristotle, which was lost. This tradition stipulated an aspect of the soul, the active intellect, that was separate and separable. This idea has inspired other and later writers into postulating an immortal part of the soul. In the modern debate this tradition has been lost and was frequently amalgamated with dualist positions. Phenomenological descriptions of mystical experiences, as well as other unusual (or exceptional)mind-matter anomalies suggest that this aspect of the problem needs reconsideration. For this purpose a transcendental kind of monism is suggested which does not violate the consensus that only a monist description of the world is scientifically viable. Such a position would, in addition, provide the option to incorporate the transpersonal side of the debate.

The debate in relation to the soul suffers nowadays from a great lack of clarity. At least part of this cloudiness stems from a confusion among three different viewpoints that are not always reconcilable or mutually intelligible: the scientific point of view (natural sciences and empirical psychology), the therapeutic point of view (especially psychoanalysis) and the philosophical point of view. The goal of this paper is to blow away a little this cloudiness, and to introduce into the discussion a view that has not yet received its proper place in it: existentialism. The scientific approach investigates the soul as if it were an object in the world, a fact. This approach gives priority to objective observations over subjective ones, and steps in the direction of materialization of the soul (the soul becomes the mind and the mind becomes the brain). Transcendental philosophy and psychological therapies explain the relation between the subject and its objects, and by this reveal the subjective dimension of our reality as the ground not only for our objective knowledge but for our ethical life as well. Existentialism, I suggest, makes a further and important step in this direction by focusing on individualistic aspects of human existence, which science could not know and general theories of the subject do not see.

The mind-body problem is the problem of explaining how our mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes in our bodies. A question of the form, ‘how is A related to B?’ does not by itself pose a philosophical problem. To pose such a problem, there has to be something about A and B which makes the relation between them seem problematic. Many features of mind and body have been cited as responsible for our sense of the problem. Here I will concentrate on two: the fact that mind and body seem to interact causally, and the distinctive features of consciousness. A long tradition in philosophy has held, with René Descartes, that the mind must be a non-bodily entity: a soul or mental substance. This thesis is called ‘substance dualism’ (or ‘Cartesian dualism’) because it says that there are two kinds of substance in the world, mental and physical or material. One reason for believing this is the belief that the soul, unlike the body, is immortal. Another reason for believing it is that we have free will, and this seems to require that the mind is a non-physical thing, since all physical things are subject to the laws of nature. To say that the mind (or soul) is a mental substance is not to say that the mind is made up of some non-physical kind of stuff or material. The use of the term ‘substance’ is rather the traditional philosophical use: a substance is an entity which has properties and persists through change in its properties. A tiger, for instance, is a substance, whereas a hurricane is not. To say that there are mental substances— individual minds or souls—is to say that there are objects which are non-material or non-physical, and these objects can exist independently of physical objects, like a person’s body. These objects, if they exist, are not made of non-physical ‘stuff’: they are not made of ‘stuff’ at all..

One familiar affirmative answer to this question holds that these facts suffice to entail that Descartes' picture of the human mind must be mistaken. On Descartes' view, our mind or soul (the only essential part of ourselves) has no spatial location. Yet it directly interacts with but one physical object, the brain of that body with which it is, 'as it were, intermingled,' so as to 'form one unit.' The radical disparity posited between a nonspatial mind, whose intentional and conscious properties are had by no physical object, and a spatial body, all of whose properties are had by no mind, has prompted some to conclude that, pace Descartes, causal interaction between the two is impossible. Jaegwon Kim has recently given a new twist to this old line of thought.(1) In the present essay, I will use Kim's argument as a springboard for motivating my own favored picture of the metaphysics of mind and body and then discussing how an often vilified account of freedom of the will may be realized within it.

This is a revised and updated version of Swinburne's controversial treatment of the eternal philosophical problem of the relation between mind and body. He argues that we can only make sense of the interaction between the mental and the physical in terms of the soul, and that there is no scientific explanation of the evolution of the soul.

In this paper I explain several ways in which Descartes denied that the human soul or mind is composite and the role this idea played in his thought. The mind is whole in the whole and whole in the parts of the body because it has no parts. Unlike body, the mind is indivisible, and this is a different idea from the thought that mind and body are incorruptible. Descartes connects the immortality of the soul with its status as a substance and as incorruptible rather than with its indivisibility.
