The connection between a mind and a brain is fundamental to the Philosophy of Mind, partly because it is often taken to include the the problem of the nature of a mind -- or, more particularly, the nature of consciousness. What follows here is an inquiry into this connection. It surveys the traditional and still orthodox answers. It is Ch. 2 of Ted Honderich's large work A Theory of Determinism: The Mind, Neuroscience and Life- Hopes -- which chapter is also Ch. 2 of the paperback Mind and Brain.

The concept of acting intentionally is an important nexus where ‘theory of mind’ and moral judgment meet. Preschool children’s judgments of intentional action show a valence-driven asymmetry. Children say that a foreseen but disavowed side-effect is brought about 'on purpose' when the side-effect itself is morally bad but not when it is morally good. This is the first demonstration in preschoolers that moral judgment influences judgments of ‘on-purpose’ (as opposed to purpose influencing moral judgment). Judgments of intentional action are usually assumed to be purely factual. That these judgments are sometimes partly normative — even in preschoolers — challenges current understanding. Young children’s judgments regarding foreseen side-effects depend upon whether the children process the idea that the character does not care about the side-effect. As soon as preschoolers effectively process the ‘theory of mind’ concept, NOT CARE THAT P, children show the side-effect effect.idea..

In the first post World War II identity theories (e.g., Place 1956, Smart 1962), mind brain identities were held to be contingent. However, in work beginning in the late 1960's, Saul Kripke (1971, 1980) convinced the philosophical community that true identity statements involving names and natural kind terms are necessarily true and furthermore, that many such necessary identities can only be known a posteriori. Kripke also offered an explanation of the a posteriori nature of ordinary theoretical identities such as that water = H2O. We identify the kinds and substances involved in theoretical identities by certain of their contingent properties. What we discover when we discover a theoretical identity is the underlying nature of the kind that we identify by those contingent properties. Now, of course, it was being a posteriori, not being contingent, that mattered to the identity theorists anyway, so the necessity of identity is not, in itself, damaging to mind brain identity theories. However, Kripke also argued persuasively that the alleged mind brain identities could not be treated in the same way as ordinary theoretical identities. We "identify" pain by feeling it, and surely how it feels is an essential property of pain, not a contingent property. Thus, a mind body identity theory must provide a different explanation of why its identities are a posteriori. A new wave of materialists has appeared on the scene with a new strategy for explaining [1] the a posteriori nature of its alleged identities. The strategy is to locate the explanation for the a posteriori nature of mind body identities, not on the side of the world, but on the side of the mind -in different ways of thinking about or imagining, or in different concepts. Thus, on this new view, there is only one property—this brain process type, which is identical with this pain..

On the evolution of mind Harry J. Jerison Most of us think of mind as a little person in the head, the 'knower' of reality (cf. Attneave,). ...

The identity theory of mind holds that states and processes of the mind are identical to states and processes of the brain. Strictly speaking, it need not hold that the mind is identical to the brain. Idiomatically we do use ‘She has a good mind’ and ‘She has a good brain’ interchangeably but we would hardly say ‘Her mind weighs fifty ounces’. Here I take identifying mind and brain as being a matter of identifying processes and perhaps states of the mind and brain. Consider an experience of pain, or of seeing something, or of having a mental image. The identity theory of mind is to the effect that these experiences just are brain processes, not merely correlated with brain processes.

Perception is sensory awareness. Cognition is reflective awareness. Consciousness is awareness-as-such. In Indian psychology, as represented by Samkhya-Yoga and Advaita Vedanta systems, consciousness and mind are fundamentally different. Reality is the composite of being (sat), knowing (cit) and feeling (ananda). Consciousness is the knowledge side of the universe. It is the ground condition of all awareness. Consciousness is not a part or aspect of the mind. Mind is physical and consciousness is not. Consciousness does not interact with the mind, the brain or any other physical objects or processes. Nor does it have any causative role in mental activity. Hence the existence of consciousness does not interfere or upset the apparently closed physical system. Mind in this view is the interfacing instrumentality that faces consciousness on one side and the brain and the rest of the physical world on the other. Mind is closely connected with the different systems of the brain. In normal perceptions, the mind takes the forms of objects via the channels of the sensory system and the processes in the brain. The forms themselves are non-conscious representations of the world of objects. The mental forms (vrittis) become conscious experiences in the light of the purusha. The vritti in sensory form is perception and with the reflection of the purusha it becomes cognition. All conscious perceptions are therefore cognitions.

Patients may show a more-or-less complete deviation of the head and eyes towards the right (ipsilesional) side [that is, to the same side of egocentric space as the brain lesion responsible for their disorder]. If addressed by the examiner from the left (contralesional) side [the opposite side to their lesion], patients with severe extrapersonal neglect may fail to respond or may look for the speaker in the right side of the room, turning head and eyes more and more to the right. Frequently these patients will not pick up food from the left half of the plate. Given a crossword puzzle, they may complete only the squares to the right. If walking is not prevented by hemiparesis, neglect patients may lose their bearings, since they do not make use of left sided cues.

Although far from unanimous, there seems to be a general consensus that neither mind nor brain can be reduced without remainder to the other. This essay argues that indeed both mind and brain need to be included in a nonreductionistic way in any genuinely integral theory of consciousness. In order to facilitate such integration, this essay presents the results of an extensive cross-cultural literature search on the "mind" side of the equation, suggesting that the mental phenomena that need to be considered in any integral theory include developmental levels or waves of consciousness, developmental lines or streams of consciousness, states of consciousness, and the self (or self-system). A "master template" of these various phenomena, culled from over one-hundred psychological systems East and West, is presented. It is suggested that this master template represents a general summary of the "mind" side of the brain-mind integration. The essay concludes with reflections on the "hard problem," or how the mind-side can be integrated with the brain-side to generate a more integral theory of consciousness.
