Bertrand Russell described this study, with its companion volume on Hegel and Marx, as 'a work of first-class importance which ought to be widely read for its masterly criticism of the enemies of democracy, ancient and modern. His (Popper's) attack on Plato, while unorthodox, is in my opinion thoroughly justified. His analysis of Hegel is deadly. Marx is dissected with equal acumen, and given his due share of responsibility for modern misfortunes. The book is a vigorous and profound defence of (...) democracy, timely, very interesting, and very well written'. 'A powerful and important book. It is a criticism of a set of dogmas which underlie the most influential political theories, and in consequence powerfully affect the actual conduct of human affairs. Dr Popper writes with extreme clarity and vigour. His studies in Greek history and Greek thought have obviously been profound and original. Platonic exegesis will never be the same again. Nor, I think, will Marxist exegesis. Readers should not miss studying the notes collected at the end of the two volumes.' - Gilbert Ryle, Mind. (shrink)

The Cambridge Companion to German Idealism offers a comprehensive, penetrating, and informative guide to what is regarded as the classical period of German philosophy. Kant, Fichte, Hegel, and Schelling are all discussed in detail, together with a number of their contemporaries, such as Hölderlin and Schleiermacher, whose influence was considerable but whose work is less well known in the English-speaking world. The essays in the volume trace and explore the unifying themes of German Idealism, and discuss their relationship to Romanticism, (...) the Enlightenment, and the culture of seventeenth- and eighteenth-century Europe. The result is an illuminating overview of a rich and complex philosophical movement, and will appeal to a wide range of readers in philosophy, German studies, theology, literature, and the history of ideas.

Joseph Addison’s (1672--1719) essays in The Spectator occupy contradictory positions in the history of aesthetics. While they are generally considered central to the institution of aesthetics as a scholarly discipline, their reception has throughout history entailed a strong questioning of their philosophical and scholarly importance. In the following paper, I consider this dual feature as regards reception, and set out to clarify how this has come about. A re-examination of the arguments advanced by Addison makes clear that his role is (...) not that of a philosopher, but that of a public educator. As such he aims to raise the standard of general education of the British ‘middling orders’ in the early eighteenth century, and by using art for didactic purposes he seeks to contribute to the shaping of morally accomplished individuals.

In the context of this publication on blindsight, I want to address further the brain processes critically responsible for organizing our conscious experience. As in a previous related publication , I am restricting myself to brain and conscious experience, not the fuller topic of ‘consciousness’ as this might be determined by genetic and environmental factors, nor as it is defined in Eastern traditions and in esoteric Western religion and philosophy. For my thoughts on this broader topic the reader is referred (...) to a recent publication prepared for the centennial celebration of Norbert Wiener's birth. That paper is entitled: ‘What is Mind that the Brain May Order It? (shrink)
