I review the book “Making Prehistory: Historical Science and the Scientific Realism Debate” by Derek Turner. Turner suggests that philosophers should take seriously the historical sciences such as geology when considering philosophy of science issues. To that end, he explores the scientific realism debate with the historical sciences in mind. His conclusion is a view allied to that of Arthur Fine: a view Turner calls the natural historical attitude. While I find Turner’s motivations good, I find his characterisation of the (...) historical sciences unconvincing. I say why in a section at the end of the review. The result is that I am unpersuaded by his thesis. (shrink)

Inconsistencies between scientific theories have been studied, by and large, from the perspective of paraconsistent logic. This approach considered the formal properties of theories and the structure of inferences one can legitimately draw from theories. However, inconsistencies can be also analysed from the perspective of modelling practices, in particular how modelling practices may lead scientists to form opinions and attitudes that are different, but not necessarily inconsistent. In such cases, it is preferable to talk about disagreement, rather than inconsistency. Disagreement (...) may originate in, or concern, a number of epistemic, socio-political or psychological factors. In this paper, we offer an account of the ‘loci and reasons’ for disagreement at different stages of the scientific process. We then present a controversial episode in the health sciences: the studies on hypercholesterolemia. The causes and effects of high levels of cholesterol in blood have been long and hotly debated, to the point of deserving the name of ‘cholesterol wars’; the debate, to be sure, isn’t settled yet. In this contribution, we focus on some selected loci and reasons for disagreement that occurred between 1920 and 1994 in the studies on hypercholesterolemia. We hope that our analysis of ‘loci and reasons’ for disagreement may shed light on the cholesterol wars, and possibly on other episodes of scientific disagreement. (shrink)

The evolution of cognition literature is dominated by views that presume the evolution of underlying neural structures. However, recent models of cognition reemphasize the role of physiological structures, development, and external resources as important components of cognition. This article argues that these alternative models of cognition challenge our understanding of human cognitive evolution. As a case study, it focuses on rehabilitating bipedalism as a crucial moment in human evolution. The australopithecines are often seen as “merely” bipedal chimpanzees, with a similar (...) suite of behaviors. But an embodied, developmental approach to understanding australopithecine cognitive abilities shows that the transition between australopithecines and the emergence of the Homo genus is less of a break than is often thought. Bipedalism on this view is not just a physiological and behavioral breakthrough: it represents a major cognitive leap as well. (shrink)

Early in 1826, at the age of 28, Charles Lyell began writing the first of a series of articles for J. G. Lockhart, the new editor of theQuarterly review. These articles gave him his first opportunity to express to the educated public his views on the state of science in general, and of geology in particular, in English society. According to the convention of theQuarterly, each article was nominally a review of one or more recently published works, but like other (...) reviewers Lyell clearly chose them as ‘pegs’ on which to hang his own arguments. In content, the articles form a kind of ‘gradualistic’ series, rather like his own later interpretations of geological phenomena. At one end of the series (though published third) was an essay on the place of science in general in English university education. Another article (the first to appear in print) focused on some of the English institutions specifically devoted to science. Here there was a hint that the need for reform in the place of science in English society was not unrelated to a similar need for reform in Lyell's chosen branch of science. The next article enlarged on this hint by examining the publications of the Geological Society of London, on which Lyell had recently served as Secretary. This essay expressed for the first time in a general context Lyell's characteristic emphasis on the need for actualistic comparison between present and past. Finally, what he needed to complete the series was an article in which he could show in detail the positive explanatory advantages of following this method in geology. The ‘peg’ which he chose for this purpose was a single work, George Poulett Scrope'sMemoir on the geology of central France. (shrink)
