A debate has been raging in the philosophy of mind for at least the past two decades. It concerns whether the mental can make a causal difference to the world. Suppose that I am reading the newspaper and it is getting dark. I switch on the light, and continue with my reading. One explanation of why my switching on of the light occurred is that a desiring with a particular content (that I continue reading), a noticing with a particular content (that it is getting dark), and a believing with a particular content (that by switching on the light I could continue reading) occurred in me, and these events caused my switching on of the light. This explanation works by citing the intentional contents of mental phenomena as causes of that action. It is because the intentional causes have the contents that they do, and because those contents play a causal role in bringing about my action, that my action is causally explained

This volume provides an introduction to and review of key contemporary debates concerning connectionism, and the nature of explanation and methodology in cognitive psychology. The first debate centers on the question of whether human cognition is best modeled by classical or by connectionist architectures. The second centres on the question of the compatibility between folk, or commonsense, psychological explanation and explanations based on connectionist models of cognition. Each of the two sections includes a classic reading along with important responses, and concludes with a specially commissioned reply by the main contributor. The editorial introductions provide a comprehensive survey and map through the debates

There is a 'philosophers' assumption that there is a problem with the very notion of an unconscious mental state.The paper begins by outlining how the problem is generated, and proceeds to argue that certain conditions need to be fulfilled if the unconscious is to qualify as mental. An explanation is required as to why we would ever expect these conditions to be fulfilled, and it is suggested that the Freudian concept of repression has an essential role to play in such an explanation. Notoriously this concept brings with it a further puzzle: it looks as though repression serves a purpose, and so requires an agent to execute this purpose, a repressor. Paradox is avoided only if repression is viewed in biologicalfunctional terms.The result is that the notion of the unconscious is saved from the a priori objections often levelled at it by philosophers.This still leaves considerable theoretical work to be done by psychological science

Alfred Jules Ayer was born in London and educated at Eton and Christ Church, Oxford. He attended sessions of the logical positivist ‘Vienna Circle’ in 1932, and taught at Oxford from 1933 until joining the Army in 1940. His Language, Truth and Logic was published in 1936, and The Foundations of Empirical Knowledge in 1940. After war service he returned to Oxford in 1945, and became Grote Professor of the Philosophy of Mind and Logic at University College, London, the following year. The Problem of Knowledge was published in 1956. In 1959 he returned to Oxord as Wykeham Professor of Logic, a post he held until his retirement in 1977. He had been made a Fellow of the British Academy in 1952, and was knighted in 1970. Among his publications after he returned to Oxford are The Concept of a Person , Philosophical Essays , The Origins of Pragmatism , Metaphysics and Common Sense , Russell and Moore: the Analytical Heritage , Probability and Evidence , The Central Questions of Philosophy , and Philosophy in the Twentieth Century
