The dry stone walls of Britain happen to be in areas which attract many tourists and so it is not surprising that the walls that are an integral part of the landscape should provoke so many questions. 'When were they built?', 'Who built them?', 'How do they stand up without cement?'. This book answers these and many other questions. The reasons for building dry stone walls, the story of their development, technical details of their construction, regional styles and the state of the craft today. Some old myths and legends are dispelled, in particular the mistaken idea that walling is a dying craft.

This polemical work presents to the English-speaking world one of the most original philosophical thinkers to have emerged within post-war Europe. Sebastiano Timpanaro is an Italian classical philologist by training, an author of scholarly studies on the nineteenth-century poet Leopardi, and a Marxist by conviction. With great force and wit, On Materialism sets itself against what it sees as the virtually universal tendency within western Marxism since the war, to dissociate historical materialism from biological or physical materialism. Whereas the philosophical legacy of the later Engels has been decried by most prominent Marxists since the 1920s, Timpanaro eloquently defends its essential purpose and relevance, by unfashionably re-emphasising the permanent weight of nature within history. In doing so, he returns to the heritage of Lucretius and Leopardi, and argues for a more consistent materialism that is at once more pessimistic and more hedonistic than any other contemporary version of Marxism. Timpanaro emphasises the insuperable limits of frailty and mortality as unalterable conditions of society whose transformation is the goal of revolutionary socialism. Timpanaro vigorously attacks what he regards as the widespread entente between a diluted Marxism and a fashionable idealism in the west, whether in the form of an "existentialist" or a "structuralist" union of the two. The aversion of the former to the work of Darwin and Engels receives a spirited refutation, no less than the indulgence of the latter towards the work of Saussure or Levi-Strauss. A special introduction written for this English edition deals with the phenomenon of the recent revival of "vulgar materialism" in the Anglo-Saxon world, in the fields of psychology and anthropology, and its relationship to racism. On Materialism will be one of the central focuses of cultural and intellectual controversy within and beyond Marxism in the next decade.

The interpretation of Hegel has been a focal point of philosophical controversy ever since the beginning of the twentieth century, both among Marxists and in the major European philosophical schools. Yet despite wide differences of emphasis most interpretations of Hegel share important similarities. They link his idea of Reason to the revolutionary and rationalist tradition which led to the French Revolution, and they interpret his dialectic as implying a latently atheist and even materialist world outlook. Lucio Colletti directly challenges this picture of Hegel. He argues that Hegel was an essentially Christian philosopher, and that his dialectic was explicitly anti-materialist in both intention and effect. In contrast to earlier views, Colletti maintains that there is no contradiction between Hegel's method and his system, once it is accepted that his thought is an exercise in Absolute Idealism stemming from a long Christian humanist tradition. He claims, on the contrary, that intellectual inconsistency is rather to be found in the works of Engels, Lenin, Lukas, Kojeve and others, who have attempted to adapt Hegel to their own philosophical priorities. Colletti places his argument in the context of a broad re-examination of the whole relationship between Marxism and the Enlightenment, giving novel emphasis to the relationship between Marxism and Kant. He concludes by re-asserting the importance in Marxism of empirical science against the claim of "infinite reason," while at the same time showing how Marx did transform key ideas in Hegelian thought to construct a consistently materialist dialectic.
