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.

Some fundamental epistemic norms govern the conduct of the activity of inquiry and the progress of theoretical deliberation. We monitor our deliberations by raising questions about how they should be conducted and about how effectively they have been carried out. Such questions ‘occur’ to us: we are often passive recipients of them. The paper discusses what determines when questions should occur to us and it investigates how far these observations can be seen as threatening our freedom of mind. These phenomena help us to see the role of states such as virtues in epistemic evaluation.

Pragmatists challenge a sharp separation of issues of theoretical and practical rationality. This can encourage a sort of anti-realism: our classifications and theories are shaped by our interests and practical concerns. However, it need not do this. A more fundamental theme is that cognition is itself an activity, the attempt to solve problems and discover truths effectively and responsibly. Evidence has to be collected, experiments have to be devised and carried out, dialogues must be engaged in with fellow inquirers, decisions must be made about when we have scrutinized our opinions enough to trust our results. Even if our goals are “purely cognitive,” the attempt to achieve them through inquiry and deliberation is an activity. The normative standards that guide its conduct, like those governing any activity, will include standards of practical rationality. Indeed, we might suggest that a belief isjustifiedso long as it is the product of responsible, well-executed inquiry.

The paper questions the common assumption that rational individuals believe all propositions which they know to be logical consequences of their other beliefs: although we must acknowledge the truth of a proposition which is a deductive consequence of our beliefs, we may not genuinely believe it. This conclusion is defended by arguing that some familiar counterexamples to the claim that knowledge is justified true belief fail because they involve propositions which are not really believed. Beliefs guide conduct or issue in assertion by answering questions which arise in the course of deliberation and conversation, but the troublesome cases present propositions which do not present the agent's answer to any question. The paper concludes by sketching the conditions under which the deductive consequences of our beliefs can be believed.1.

The paper explores Quine's ?naturalized epistemology?, investigating whether its adoption would prevent the description or vindication of normative standards standardly employed in regulating beliefs and inquiries. Quine's defence of naturalized epistemology rejects traditional epistemological questions rather than using psychology to answer them. Although one could persuade those sensitive to the force of traditional epistemological problems only by employing the kind of argument whose philosophical relevance Quine is committed to denying, Quine can support his view by showing how scientific inquiry need not confront any evaluative issues which cannot be addressed in naturalistic terms. A survey of Quine's own epistemological writings supports this account of his position: naturalized epistemology, it is argued, requires acceptance of the shallowness of epistemic reflection, and traditional epistemology employs general epistemic norms and principles which Quine endeavours to show that we can do without. The closing sections of the paper argue that Quine can consistently resist recent criticisms by Alvin Plantinga in spite of the fact that an unsympathetic reader could reasonably be unimpressed by this resistance. Finally, an attempt is made to understand the normative role of Quine's empiricism and of his claim that prediction is the checkpoint of inquiry
