This book is based on previously unpublished lectures that Wisdom delivered at the University of Virginia. Its content goes significantly beyond that of his other books. Here he is concerned with how misunderstandings about what it is to prove something or what it is to explain something can infect our thinking in many different fields.

Instrumentalism is an approach to science that treats a theory as a tool and only as a tool for computation; it dispenses with the concept of truth.Conventionalism treats a theory as true by convention if it forms a pattern of observations from which correct predictions can be made.Operationalism denies meaning to the concepts of a theory unless they can be defined operationally. It is argued in this paper that truth-value is indispensable to science, because a theory can be rejected only (...) if an empirical consequence is false and if falsity of a conclusion entails falsity of a premise. This undermines the above positions. The fourth interpretation isinduction. Induction, by contrast, uses the notion of truth-value. What is focused on here is its reliance on the ultimacy ofobservation. The present thesis is that instrumentalism, conventionalism, and induction are different attempts to handle observations. The common problem is the gap between data and theory.All these interpretations share a philosophy of observationalism. The aim of this paper is to show that the several orthodox interpretations of science all fail to solve the problem of the data-theory gap, and to show that they all presuppose a philosophy of observation.

Professor Wisdom gives an elementary introduction to the applications in philosophy of the analytical method. He believes that the aim of analysis is clarity, whereas the aim of speculative philosophy is truth. After a brief introduction on what analysis is, he discusses the relation of body and mind and seeks for causal relations between mental and material events. He concludes this section with a chapter on Free will, before turning to perception and the external world.

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

Nearly 30 years ago, Terry Horgan and Mark Timmons published a now- popular article that combines Hilary Putnam’s Twin Earth scenario with G.E. Moore’s open question argument in an effort to show that moral naturalism – the view that moral facts are at bottom ordinary, natural facts of some sort – is probably false. Responses to Horgan and Timmons’s “revised open question argument” have been legion, but surprisingly, no one has attempted to test the core assumption upon which the argument (...) is based; namely, that competent language users univocally treat natural kind-terms as rigid designators. Here, I present evidence that the intuitions of competent English speakers are not as univocal as Horgan and Timmons need them to be to ground their argument against moral naturalism. I also briefly sketch a way that the moral naturalist can respond even if competent language speakers do treat natural-kind terms in the way that Horgan and Timmons suggest. (shrink)

I Fear you will be disappointed in what I have to say. For I am going to talk about those who, though they have said ‘There is a way to eternal life’, have then gone on to explain that what they mean does not imply that there is a way to a life that endures for ever or even a life after death. It is plain that those who do this take from the words ‘There is a way to eternal (...) life’ a part of their meaning which has been and still is to very many people of very great importance. Nevertheless between those who when they speak of a way to eternal life are thinking of a life after death which endures for ever, and those who when they speak of eternal life give to their words a meaning which carries no implication as to whether there is a life after death, there is a link, in that both are seeking a remedy against a sort of despair which comes not merely from the thought of death but from a disappointment with life together with the thought that it ends in death.

A common line of thought in contemporary metaethics is that certain facts about the evolutionary history of humans make moral realism implausible. Two of the most developed evolutionary cases against realism are found in the works of Richard Joyce and Sharon Street. In what follows, I argue that a form of moral realism that I call proper-function moral realism can meet Joyce and Street's challenges. I begin by sketching the basics of proper-function moral realism. I then present what I take (...) to be the essence of Street's and Joyce's objections, and I show how proper-function realism answers them. (shrink)

Originally published in 1952. This book is a critical survey of the views of scientific inference that have been developed since the end of World War I. It contains some detailed exposition of ideas – notably of Keynes – that were cryptically put forward, often quoted, but nowhere explained. Part I discusses and illustrates the method of hypothesis. Part II concerns induction. Part III considers aspects of the theory of probability that seem to bear on the problem of induction and (...) Part IV outlines the shape of this problem and its solution take if transformed by the present approach. (shrink)

Some twenty different background approaches, or schemata, permeate the social sciences. Most of their exponents regard their choice as excluding the rest. This paper is concerned to show that all such conflict is merely disputatious since virtually all the schemata require one another. Taking the individual's need to act as starting-point, certain restrictions limiting his freedom of action are identified as factors of the overt societal situation. These, however, fail to explain all aspects of his powerlessness, to account for which (...) he then seeks such deeper constraints as unseen powers or human conspiracies. Social scientists for their part develop theories or interpretations of the societal situation. The paper turns to the first of three groups of interpretations, concentrating on one constituent of the group, functionalism, which is a mirror-image of another constituent, 'conflict theory'. The complementarity of these two is claimed to apply to virtually all the schemata considered. (The second and third groups are deferred to the sequel.) The Appendix deals with the way in which explanatory factors can be combined. Having removed the unreal contentions associated with various schemata, the way is clear to treatment of the one substantive issue among them - to do with holism - in the sequel. (shrink)

1. ‘How do we know the material world?’, ‘What is it to know the material world?’, ‘In what ways is knowledge of the material world like and in what ways is it unlike other sorts of knowledge?’ We know how we know the material world and what it is to know the material world and in what ways such knowledge is like and unlike other sorts of knowledge. But a man who knows what poetry is like and how it is (...) like and unlike prose may ask ‘What is poetry?’, and a mathematician who knows what it is like to do mathematics may ask ‘What is mathematics?’ It is in a rather like way that we ask ‘What is knowledge of the material world?’ The ways in which knowledge of the material world is like and unlike other sorts of knowledge are familiar to us but we wish for a still better grasp of these likenesses and unlikenesses.

Conflicting Systems in the History of Philosophy. Hegel's logic consists, as is well known, in a chain of categories, connected by a relation of dialectic, which proceeded from the featureless Being, Nothing, and Becoming through more important ones such as Substance, Cause, and Reciprocity to the highest category of all, the Absolute Idea. Now Hegel also pointed to an interesting correlation between the categories of his logic and the dominant concepts of those philosophies that preceded his own: that is to (...) say, the logical order of categories given by him corresponded to the temporal order of the history of philosophy. Such connexion was not, however, to be regarded as an accident but as a necessary truth: for the Absolute manifested itself temporally in the form of the history of philosophy. Seeing that this contention probably contains some psychological truth and is probably assumed in Marxian interpretations of Hegel, it may be of some interest to see how far it can be substantiated.
