It has long been thought that the ancient Greeks did not take mechanics seriously as part of the workings of nature, and that therefore their natural philosophy was both primitive and marginal. In this book Sylvia Berryman challenges that assumption, arguing that the idea that the world works 'like a machine' can be found in ancient Greek thought, predating the early modern philosophy with which it is most closely associated. Her discussion ranges over topics including balancing and equilibrium, lifting water, (...) sphere-making and models of the heavens, and ancient Greek pneumatic theory, with detailed analysis of thinkers such as Aristotle, Archimedes, and Hero of Alexandria. Her book shows scholars of ancient Greek philosophy why it is necessary to pay attention to mechanics, and shows historians of science why the differences between ancient and modern reactions to mechanics are not as great as was generally thought.

In this paper I address Descartes’ use of analogy in physics. First, I introduce Descartes’ hypothetical reasoning, distinguishing between analogy and hypothesis. Second, I examine in detail Descartes’ use of analogy to both discover causes and add plausibility to his hypotheses—even though not always explicitly stated, Descartes’ practice assumes a unified view of the subject matter of physics as the extension of bodies in terms of their size, shape and the motion of their parts. Third, I present Descartes’ unique “philosophy (...) of analogy”, where the absence of analogy serves as a criterion for falsifying proposed explanations in physics. I conclude by defending Descartes’ philosophy of analogy by appeal to the value scientists assign to simplicity in their explanations. (shrink)

This paper describes and analyses a hitherto unknown document of considerable historical significance: a narrative diary of the weather for every day of the year 1703. Available evidence enables us to assign the authorship of the document, with a high degree of probability, to an Oxford graduate residing in rural Worcestershire. The text presents plentiful natural philosophical speculations about the causes of meteorological phenomena, drawing both upon the ideas of leading scientific thinkers and upon vernacular lore concerning the weather. Furthermore, (...) the diarist composed a remarkably personal document, in a richly descriptive style, cataloguing his physiological and emotional reactions to prevailing weather conditions. The document thus represents an empathic and discursive style of meteorology, an alternative to the contemporary efforts to establish objective weather records that have previously been recognized by historians.
