Theory of Mind is the branch of cognitive science that investigates how we ascribe mental states to other persons and how we use the states to explain and predict the actions of those other persons. More accurately, it is the branch that investigates mindreading or mentalizing or mentalistic abilities. These skills are shared by almost all human beings beyond early childhood. They are used to treat other agents as the bearers of unobservable psychological states and processes, and to anticipate and explain the agents’ behavior in terms of such states and processes. These mentalistic abilities are also called “folk psychology” by philosophers, and “na?ve psychology” and “intuitive psychology” by cognitive scientists.
Perhaps no other classical philosophical tradition, East or West, offers a more complex and counter-intuitive account of mind and mental phenomena than Buddhism. While Buddhists share with other Indian philosophers the view that the domain of the mental encompasses a set of interrelated faculties and processes, they do not associate mental phenomena with the activity of a substantial, independent, and enduring self or agent. Rather, Buddhist theories of mind center on the doctrine of not-self (P?li anatta, Skt. an?tma), which postulates that human beings are reducible to the physical and psychological constituents and processes which comprise them.
Indian Buddhist analyses of the mind span a period of some fifteen centuries, from the earliest discourses of the Buddha (ca. 450 B.C.E.) to the systematic developments of late Mah?y?na Buddhism (500–1000 C.E.). Although philosophical accounts of mind emerge only within the Abhidharma scholastic traditions (roughly 150 B.C.E. to 450 C.E.), their roots are found in the Buddha's teachings of the not-self doctrine. At the same time, these accounts parallel similar theoretical developments within the Brahmanical traditions, with which they share a common philosophical vocabulary (and a general view of mental processes as hierarchical and discrete). This article focuses on the picture of mind and mental phenomena that emerges from the canonical literature, the theories of mind advanced by the main Abhidharma scholastic traditions, and the epistemological issues of perception and intentionality debated by philosophers such as Vasubandhu, Dign?ga, Dharmak?rti, Candrak?rti, ??ntarak?ita, and Dharmottara.
Immanuel Kant (1724-1804) was one of the most important philosophers of the Enlightenment Period (c. 1650-1800) in Western European history. This encyclopedia article focuses on Kant’s views in the philosophy of mind, which undergird much of his epistemology and metaphysics. In particular, it focuses on metaphysical and epistemological doctrines forming the core of Kant’s mature philosophy, as presented in the Critique of Pure Reason (CPR) of 1781/87 and elsewhere.
There are certain aspects of Kant’s project in the CPR that should be very familiar to anyone versed in the debates of seventeenth century European philosophy. For example, Kant argues, like Locke and Hume before him, that the boundaries of substantive human knowledge stop at experience, and thus that we must be extraordinarily circumspect concerning any claim made about what reality is like independent of all possible human experience. But, like Descartes and Leibniz, Kant thinks that central parts of human knowledge nevertheless exhibit characteristics of necessity and universality, and that, contrary to Hume’s skeptical arguments, there is good reason to think so.
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.
Some philosophers hold that though experiences are brain processes they nevertheless have fundamentally non-physical, psychical, properties, sometimes called ‘qualia’. Here I shall take the identity theory as denying the existence of such irreducible non-physical properties. Some identity theorists give a behaviouristic analysis of mental states, such as beliefs and desires, but others, sometimes called ‘central state materialists’, say that mental states are actual brain states. Identity theorists often describe themselves as ‘materialists’ but ‘physicalists’ may be a better word. That is, one might be a materialist about mind but nevertheless hold that there are entities referred to in physics that are not happily described as ‘material’.
