This is a volume of original essays written by philosophers and scientists and dealing with philosophical questions arising from work in evolutionary biology and artificial intelligence. In recent years both of these areas have been the focus for attempts to provide a scientific, model of a wide range of human capacities - most prominently perhaps in sociobiology and cognitive psychology. The book therefore examines a number of issues related to the search for a 'naturalistic' or scientific account of human experience and behaviour. Some of the essays deal with the application of such models to particular behaviour, stressing the problems raised by consciousness, and the information to be derived from the differing capacities of animals and people; others consider more general questions about the logic of the explanations provided by these kinds of approach. The volume continues the informal series stemming from meetings sponsored by the Thyssen Foundation.

We can characterise thought in two different ways. Which is preferred can have implications for important issues about reasoning and the norms that govern cognition. The first, which owes much to the picture of the mind encountered in Descartes' Meditations, observes that paradigmatic examples of thoughts and inferences are events and processes whose special characteristics stem from their being ‘mental’ occurrences. For example they are conscious or, if unconscious, they stand in some special relation to thought processes that are conscious. They typically involve attitudes towards contents or propositions. In general, thoughts have a distinctive onto-logical status and this status depends upon their being mental and typically conscious. The second emphasises that thought is a kind of activity with a definite function. It involves the use of intelligence to solve problems, answer questions, make plans and so on. Thought should be studied as a kind of goal-directed activity. Those interested in the norms that govern thought should attend to the role of responsible disciplined reflection in carrying out this activity.

William James’s paper “The Will to Believe” defends some distinctive and controversial views about the normative standards that should be adopted when we are reflecting upon what we should believe. He holds that, in certain special kinds of cases, it is rational to believe propositions even if we have little or no evidence to support our beliefs. And, in such cases, he holds that our beliefs can be determined by what he calls “passional considerations” which include “fear and hope, prejudice and passion, imitation and partisanship, the circumpressure of our caste and set” (1897: 9). On most occasions “we find ourselves believing, we hardly know how or why.” When James allows passional considerations a major role in determining the rationality of belief and argues that it is rational to form beliefs in advance of the evidence, he can easily be understood as holding that belief can be responsible when it is not warranted by epistemological norms. Belief can be rational and responsible when the reasons which support it are entirely prudential or practical. The question I am concerned with here is: how far can James’s argument in “The Will to Believe” be understood as an application of some views which are genuinely epistemological? One question we can ask about these views is: how far are they an application of a distinctively pragmatist approach to epistemological concerns about when belief is justified? One possibility is that James is making some original contributions to epistemology which may have echoes in contemporary epistemology. I shall argue that this interpretation of James’s argument is more plausible than it at first appears.
