The fame of Ludwig Wittgenstein as one the most important and original philosophers of the century-and also as an intense, magnetic personality-has grown steadily since his death in 1951.

In _Probability and Evidence_, one of Britain's foremost twentieth-century philosophers addresses central questions in the theory of knowledge and the philosophy of science. This book contains A.J. Ayer's John Dewey Lectures delivered at Columbia University, together with two additional essays, "Has Harrod Answered Hume?" and "The Problem of Conditionals.".

The volume documents, and makes an original contribution to, an astonishing period in twentieth-century philosophy—the progress of Arne Naess's ecophilosophy from its inception to the present. It includes Naess's most crucial polemics with leading thinkers, drawn from sources as diverse as scholarly articles, correspondence, TV interviews and unpublished exchanges. The book testifies to the skeptical and self-correcting aspects of Naess's vision, which has deepened and broadened to include third world and feminist perspectives. Philosophical Dialogues is an essential addition to the (...) literature on environmental philosophy. (shrink)

This is a representative collection of the work of A.J. Ayer, one of the most influential contemporary philosophers. It includes his Whidden lectures on freedom and morality, which were presented at McMaster University in 1983, a previously unpublished essay on J.L. Mackie's Theory of Causal Priority, and seven other essays which cover such topics as: references and identity, the causal theory of perception, the prisoner's paradox, self-evidence and certainty, and the history of the Vienna Circle.

Summary By means of examples drawn from everyday experience, the author investigates what conditions must be satisfied in order that behaviour may be called rational or irrational. Does the attribution of irrationality apply to means or to ends? Is it based on consideration of the total cost? Is heroism irrational? Cannot what is irrational for one person be rational for another? Finally, the author uses this approach to come to the problem of induction and to that of moral freedom.RésuméL'auteur examine, (...) à l'aide d'exemples divers tiréds de l'expérience quotidienne, quelles sont les conditions qui doivent ětre remplies pour qu'on puisse qualifier une conduite de rationnelle ou d'irrationnelle. L'imputation d'irrationalité concerne‐t‐elle les moyens ou les buts? Se fonde‐t‐elle sur une estimation globale des coǔts? L'héroïsme est‐il irrationnel? Ce qui est irrationnel pour l'un ne peut‐il pas ětre rationnel pour un autre? Enfin, il aborde par ce biais le problème de l'induction et celui de la liberté morale.ZusammenfassungDer Verfasser untersucht aufgrund verschiedener aus dem Alltag gezogenen Beispiele die Frage, welches die Bedingungen sind, die erfüllt sein müssen, damit man ein Verhalten als rational bezeichnen kann. Bezieht sich das Zuschreiben von Irrationalität auf Mittel oder auf Ziele? Ist es auf der Einschätzung des Aufwandes begründet? Ist Heldentum irrational? Kann das, was dem einen als irrational gilt, einem andern nicht als rational gelten? Schliesslich wird über das Induktionsproblem das Problem der moralischen Freiheit angegangen. (shrink)
