Wittgenstein, possibly the most influential philosopher of the twentieth century, is often labelled a Neopositivist, a New-Kantian, even a Sceptic. Questions on Wittgenstein, first published in 1988, presents a selection of nine essays investigating a matter of vital philosophical importance: Wittgenstein’s relationship to his Austrian predecessors and peers. The intention throughout is to determine the precise contours of Wittgenstein’s own thought by situating it within its formative context. Although it remains of particular interest to Anglo-Saxon philosophers, special familiarity with Austrian philosophy is required to appreciate the subtle and profound influence which this cultural and philosophical setting had on Wittgenstein’s intellectual development. Professor Haller has spent his career exploring these themes, and is one of the foremost authorities on both Wittgenstein and contemporary Austrian philosophy. Questions on Wittgenstein thus offers a unique insight into the twentieth-century tradition of Austrian philosophy, and its importance for Wittgenstein’s thought.

Wittgenstein’s Intentions, first published in 1993, presents a series of essays dedicated to the great Wittgenstein exegete John Hunter. The problematic topics discussed are identified not only by Wittgenstein’s own philosophical writings, but also by contemporary scholarship: areas of ambiguity, perhaps even confusion, as well as issues which the father of analytic philosophy did not himself address. The difficulties involved in speaking cogently about religious belief, suspicion, consciousness, the nature of the will, the coincidence of our thoughts with reality, and transfinite numbers are all investigated, as well as a variety of other intriguing questions: why can’t a baby pretend to smile? How do I know what I was going to say? Wittgenstein’s Intentions is an invaluable resource for students of Wittgenstein as well as scholars, and opens up a wide horizon of philosophical questioning for those as yet unfamiliar with this style of reasoning.

Philosophers since Descartes have felt themselves compelled to make a choice between mind and body. Wittgenstein’s Philosophy of Mind, first published in 1986, argues that there is no genuine epistemological problem of mind, and that the widespread philosophical scepticism with regard to our knowledge of other minds is without foundation. Ashok Vohra applies Wittgenstein’s method to show that the problem has arisen through a tendency to over-philosophise our simple experiences. Vohra presents a positive account of Wittgenstein’s philosophy of mind, arguing that to consider his philosophy entirely destructive is misleading. He shows that knowledge of mind is gained through a large complex of intersubjectively identifiable factors such as the linguistic and non-linguistic past, present and future behaviour of the person concerned. He thus justifies the belief, on which psychology and psychoanalysis are based, that mind is not a mystery to which only the owner has privileged access.

Wittgenstein’s philosophical achievement lies in the development of a new philosophical method rather than in the elaboration of a particular philosophical system. Dr Paul Johnston applies this innovative method to the central problems of moral philosophy: whether there can be ‘truth’ in ethics, or what the meaning of objectivity might mean in the context of moral deliberation. Wittgenstein and Moral Philosophy, first published in 1989, represents the first serious and rigorous attempt to apply Wittgenstein’s method to ethics. The conclusions arrived at differ radically from those dominating contemporary ethical discussion, revealing an immense discrepancy between the ethical concepts employed in everyday moral decision-making and the way in which these are discussed by philosophers. Dr Johnston examines ways of eliminating this discrepancy in order to gain a clearer picture of the proper nature of moral claims, and at the same time provides new insights into Wittgenstein’s conception of philosophy.

On Being in the World, first published in 1990, illumines a neglected but important area of Wittgenstein’s philosophy, revealing its pertinence to the central concerns of contemporary analytic philosophy. The starting point is the idea of ‘continuous aspect perception’, which connects Wittgenstein’s treatment of certain issues relating to aesthetics with fundamental questions in the philosophy of psychology. Professor Mulhall indicates parallels between Wittgenstein’s interests and Heidegger’s Being and Time, demonstrating that Wittgenstein’s investigation of aspect perception is designed to cast light on much more than a bizarre type of visual experience: in reality, it highlights what is distinctively human about our behaviour in relation to things in the world, what it is that distinguishes our practical activity from that of automata. On Being in the World remains an invaluable resource for students of Wittgenstein’s philosophy, as well as anyone interested in negotiating the division between analytic and continental philosophy.

First published in 1989, this book tackles a relatively little-explored area of Wittgenstein’s work, his philosophy of psychology, which played an important part in his late philosophy. Writing with clarity and insight, Budd traces the complexities of Wittgenstein’s thought, and provides a detailed picture of his views on psychological concepts. A useful guide to the writings of Wittgenstein, the book will be of value to anyone concerned with his work as a whole, as well as those with a more general interest in the philosophy of psychology.

Peter Munz, a former student of both Popper and Wittgenstein, begins his comparison of the two great twentieth-century philosophers, by explaining that since the demise of positivism there have emerged, broadly speaking, two philosophical options: Wittgenstein, with the absolute relativism of his theory that meaning is a function of language games and that social configurations are determinants of knowledge; and Popper’s evolutionary epistemology – conscious knowledge is a special case of the relationship which exists between all living beings and their environments. Professor Munz examines and rejects the Wittgensteinian position. Instead, Our Knowledge of the Growth of Knowledge, first published in 1985, elaborates the potentially fruitful link between Popper’s critical rationalism and Neo-Darwinism. Read in the light of the latter, Popper’s philosophy leads to the transformation of Kant’s Transcendental Idealism into ‘Hypothetical Realism’, whilst the emphasis on the biological orientation of Popper’s thought helps to illumine some difficulties in Popper’s ‘falsificationism’.
