Continental philosophy of science has developed alongside mainstream analytic philosophy of science. But where continental approaches are inclusive, analytic philosophies of science are not–excluding not merely Nietzsche’s philosophy of science but Gödel’s philosophy of physics. As a radicalization of Kant, Nietzsche’s critical philosophy of science puts science in question and Nietzsche’s critique of the methodological foundations of classical philology bears on science, particularly evolution as well as style (in art and science). In addition to the critical (in Mach, Nietzsche, Heidegger (...) but also Husserl just to the extent that continental philosophy of science tends to depart from a reflection on the crisis of foundations), other continental philosophies of science include phenomenology (Husserl, Bachelard, Merleau‐Ponty, etc.) and hermeneutics (Heidegger, Gadamer, Heelan, etc.), especially incorporating history of science (Nietzsche, Mach, Duhem, Butterfield, Feyerabend, etc.). Examples are drawn from the philosophy of sciences (chemistry, geology, and biology) other than physics. (shrink)

Phillip Sloan has thoroughly documented the importance of Darwin's general invertebrate research program in the period from 1826 to 1836 and demonstrated how it had an impact on his conversion to transformism. Although Darwin later spent eight years of his life investigating barnacles, this period has received less treatment in studies of Darwin and the development of his thought. The most prominent question for the barnacle period that has been attended to is why Darwin "delayed" in publishing his theory of (...) evolution. A related but distinct question concerns the variety of earlier events and influences that led Darwin to the study of "Cirripedia" in 1846, apart from its role in the trajectory that led to "On the Origin of Species ". In this paper I focus on four specific episodes prior to 1846 that inform a picture of why Darwin had an antecedent interest in barnacles: the orientation to collecting strange and curious invertebrate organisms, as well as the strong affinities of Darwin's invertebrate collecting on the Beagle voyage with the work of John Vaughan Thompson; the critical role of marine invertebrate fossils in Darwin's geological reasoning aboard the Beagle and exemplified in his "Geological Observations of South America;" the strange absence of a "Zoology of the Beagle" volume on invertebrates and Darwin's original intent to publish some of the descriptions himself; and the noteworthy presence of barnacles in Darwin's transformation theorizing between 1837 and 1839. There is a wealth of support for the thesis that Darwin had a strong interest in cirripedes prior to the formal barnacle research, blunting arguments that it was psychological aversion or a feeling of inferiority about his taxonomic abilities that drove Darwin to the cirripedes.

A detailed account is given of the development of the Archaean Controversy in Caernarvonshire and Anglesey. Sedgwick had found no base for his Cambrian in North Wales, but had intimated that some of the unfossiliferous rocks of the Lleyn Peninsula and Anglesey might be older than his Cambrian. He also described two ‘ribs’ of igneous rock: one running from Caernarvon to Bangor; the other inland, parallel to the first and crossing the Llanberis Pass at Llyn Padarn. The early Surveyors supposed (...) that these ‘ribs’ had altered the surrounding rocks, and the resulting ‘Altered Cambrian’ could be traced across the Menai Strait to Anglesey, where it formed the various metamorphic rocks of that island. This view was challenged by the usual coalition of ‘amateurs’ with attempts being made to recognize a sequence of Archaean rocks in North Wales similar to that in Pembrokeshire. However, vigorous debate occurred amongst the ‘Archaean’ geologists themselves, especially about a rock at Twt Hill, Caernarvon, and about a claimed unconformity at the base of the Cambrian in the Llanberis Pass, perhaps adjacent to the Llyn Padarn ‘rib’. Vigorous debate took place about the location of the claimed Llanberis unconformity, but the ‘Archaeans’ were united in regarding the metamorphic rocks of Anglesey as Precambrian. Eventually, the greywackes of Anglesey, and around Bangor and Caernarvon, were identified as Ordovician, not Cambrian. Very detailed map-work in Anglesey was carried out privately by Edward Greenly, and his results were published by the Survey in the form of a map and a high-quality Memoir. Greenly utilized for Anglesey tectonic ideas derived from his earlier fieldwork in the Scottish Highlands, so that although his mapping and stratigraphical divisions have proved to be of permanent value it is believed that his structures for Anglesey were mistaken and his stratigraphic sequence inverted. The Survey eventually abandoned its earlier model of Anglesey without too much difficulty; and the igneous ‘rib’ of Llyn Padarn is now construed as an ignimbrite. However, a definite base for the Cambrian has still not been found in Caernarvonshire, and the stratigraphical evidence for the Precambrian age of the Anglesey rocks remains incomplete. The study reveals the great difficulty experienced by early geologists when working in unfossiliferous rocks, the evidence from included fragments proving particularly uncertain. The paper also examines further the community of nineteenth-century British geologists, with their various factions and competing interests. (shrink)

The prevailing view among historians of science holds that Charles Darwin became a convinced transmutationist only in the early spring of 1837, after his Beagle collections had been examined by expert British naturalists. With respect to the fossil vertebrate evidence, some historians believe that Darwin was incapable of seeing or understanding the transmutationist implications of his specimens without the help of Richard Owen. There is ample evidence, however, that he clearly recognized the similarities between several of the fossil vertebrates he (...) collected and some of the extant fauna of South America before he returned to Britain. These comparisons, recorded in his correspondence, his diary and his notebooks during the voyage, were instances of a phenomenon that he later called the “law of the succession of types.” Moreover, on the Beagle, he was following a geological research agenda outlined in the second volume of Charles Lyell’s Principles of Geology, which implies that paleontological data alone could provide an insight into the laws which govern the appearance of new species. Since Darwin claims in On the Origin of Species that fossil vertebrate succession was one of the key lines of evidence that led him to question the fixity of species, it seems certain that he was seriously contemplating transmutation during the Beagle voyage. If so, historians of science need to reconsider both the role of Britain’s expert naturalists and the importance of the fossil vertebrate evidence in the development of Darwin’s ideas on transmutation.

ArgumentDarwin's narrative of the earthquake at Concepción, set within the frameworks of Lyellian uniformitarianism, romantic aesthetics, and the emergence of geology as a popular science, is suggestive of the role of the sublime in geological enquiry and theory in the early nineteenth century. Darwin'sBeaglediary and later notebooks and publications show that the aesthetic of the sublime was both a form of representing geology to a popular audience, and a crucial structure for the observation and recording of the event from the (...) beginning. The awesome spectacle of the earthquake proved in turn the magnitude of the forces at stake in earth history, and helped to make geology an epic conjoining the history of civilization with the history of the earth.

1831 was a momentous year for Charles Darwin. He passed his BA examination on 22 January, stayed up in Cambridge for two further terms and returned to The Mount, his home in Shrewsbury, in mid-June. On 6 August he left Shrewsbury with Adam Sedgwick for a geological field trip to North Wales, and after his lone traverse over the Harlech Dome returned to The Mount on Monday 29 August to find letters from John Stevens Henslow and George Peacock inviting him (...) to joint HMS Beagle. This geological field trip was crucial for his work on the Beagle. For example, when he began his first geological work of the voyage on Quail Island, he was by that time a competent geologist. Though others have studied the North Wales tour in some detail, there is also another earlier and much briefer episode to consider. Darwin appears to have geologized on his own at Llanymynech in July. The contrast between his first recorded attempts at Llanymynech in July 1831 and then elsewhere in North Wales in August 1831 is most instructive, as his development as a geologist can be followed in his field notes. Retracing his steps today, and comparing his measurements and observations with new ones, throws light on what he might have learnt at different points during that summer. (shrink)
