The history of the dyestuffs industry during the period 1775–1860 is interesting for three reasons. In the first place it was in connection with the manufacture of synthetic dyestuffs, begun in 1856, that the industrial research laboratory and the organization scientist first unmistakably appeared in the last decades of the nineteenth century. Secondly, there are the enigmas of W. H. Perkin, the man who discovered and manufactured the first coal-tar colours, but who retired somewhat abruptly from the industry in 1874: (...) just after the synthesis of alizarine. Thirdly, the dyestuffs industry was in intimate association with the textile industries which had for a long time been subject to frequent radical scientific and technological innovation. Among the most important of these we may mention John Smeaton's classic paper of 1759 on the maximum work obtainable from a given fall of water: a problem important not only for the abstract science of mechanics, but also for the design of waterwheels—the main source of power for the early textile mills. (The waterwheel was not, during the eighteenth century, the epitome of the quaint and picturesque: it was in the van of scientific and technical progress.) Again, the textile industries were quick to employ the Watt rotative engine; previously a two cylinder Newcomen engine had been tried out. Bleaching powders, based on Scheele's discovery of chlorine and its properties, were rapidly adopted: in this context one cannot help contrasting the indifference of medical science to Davy's early suggestion of using nitrous oxide as an anaesthetic; or Faraday's comment in 1818 on the anaesthetic power of sulphuric ether. The textile industries saw, over this period, a rapid succession of new machines, the pace of invention being so hot that in 1832 Charles Babbage reported that machines became obsolete long before they wore out. A Salford cotton mill was the first industrial establishment to use gas lighting: James Thomson, calico printer, introduced gas lighting to the town of Clitheroe when he installed it in his works. And there were many other important technical and scientific innovations. It was to supply these industries, so well accustomed to change, that the synthetic coal-tar dyestuffs were introduced from 1856 onwards. It is interesting that, so far as we can see, the appearance of these synthetic dyestuffs was the last in the series of major innovations in the textiles and related industries: at least until recent times.

This paper defends the view of continuants as 'four-dimensional worms' against an argument of Geach's. This is to the effect that if continuants are four-dimensional worms then their stages either do, or do not, fall under the very general terms satisfied by the continuants themselves (a stage of a man either is, or is not, a man); but that either alternative is untenable. I try to show how the former alternative may be defended by appealing to some of Geach's own (...) ideas about identity; then go on to defend the four-dimensionalist view from a criticism of it by Mellor, and finish with an account of the intuitive distinction between process and continuant terms.

Thomas Kuhn's shadow hangs over almost every field of intellectual inquiry. His book The Structure of Scientific Revolutions has become a modern classic. His influence on philosophy, social science, historiography, feminism, theology, and (of course) the natural sciences themselves is unparalleled. His epoch-making concepts of 'new paradigm' and 'scientific revolution' make him probably the most influential scholar of the twentieth century. Sharrock and Read take the reader through Kuhn's work in a careful and accessible way, emphasizing Kuhn's detailed studies of (...) the history of science, which often assist the understanding of his more abstract philosophical work. These historical studies provide vital insight into what Kuhn was actually trying to achieve in his The Structure of Scientific Revolutions: an endeavour far less extreme than either his 'foes' or his 'fans' claim. In the book's second half, Sharrock and Read provide excellent explications, defences and, where appropriate, criticisms of Kuhn's central concept of 'incommensurability', and tackle head on the crucial issue of whether Kuhn's insights concerning the natural sciences can be extrapolated to other disciplines, such as the social sciences. This is the first comprehensive introduction to the work of Kuhn and it will be of particular interest to students and scholars in philosophy, theory of science, management science and anthropology.
