There are many good reasons for seeing Aristotelian hylemorphism and atomism as diametrically opposed theories of matter. Aristotle himself had forcefully combatted the physical model of Leucippus and Democritus, whose ontology consisted of indivisible material bodies moving in an immaterial void, presenting his own model as an alternative. This alternative excluded both indivisibles and the void and postulated instead a plenist world made up of substances all of which were infinitely divisible continua composed of universal matter and specific substantial forms. (...) Unlike elementary atoms, Aristotle’s elementary substances could transmute into one another: water, when evaporating, was said to turn into air. (shrink)

We are all used to drawing straight lines to represent time, and above them, we plot historical events or physical or economic data. What to us is a self-evident convention, is however of an astonishingly recent date: it emerged only in the second half of the eighteenth century. To us, this late date seems paradoxical and cries out for an explanation. How else did earlier periods measure change, if not as a function of time? it will be argued that since (...) Antiquity, time was taken to measure change, and change to occur in space. ‘Our’ idea of representing time as an independent dimension would have seemed aberrant. But then, a second issue arises. Did not medieval natural philosophers employ timelines, Oresme’s diagram of the mean speed theorem being the most famous case? However, as will be shown, our interpretation of his diagram is probably wrong. This insight, in turn, takes care of a third paradox, namely Galileo’s initial inability to represent the law of free fall correctly. This article will document that the timeline first emerged in the late sixteenth century in works on chronology, made its first appearance in physics in Galileo’s diagrams, and had its general breakthrough in the eighteenth century.

Daniel Sennert is one of the more neglected big figures of that seventeenth-century process that goes by the shorthand name of Scientific Revolution. Born in Breslau/wroclaw in 1572, he was professor of medicine at the University of Wittenberg from 1602 until his death in 1637. However, his fame and importance were not due to his classroom teaching but to his writings, which were reprinted throughout the century in Germany, France, England, Italy, and the Netherlands, and partially translated into English. His (...) reputation among both his contemporaries and today’s historians of science has to do with the highly innovative synthesis of natural philosophy, medicine, and chymistry, which he presented notably in the two editions of his De chymicorum cum Aristotelicis et Galenicis consensu ac dissensu and in his late Hypomnemata physica, both of which relied on a novel type of atomistic matter theory. His influence, generally underestimated in today’s scholarship, was felt throughout the century and, as William R. Newman has demonstrated, is particularly important in the case of Robert Boyle, who was “plundering Sennert’s œuvre for proofs of the corpuscularian hypothesis,” albeit without acknowledging his source.

This book explores the dynamics of the commentary and textbook traditions in Aristotelian natural philosophy under the headings of doctrine, method, and scientific and social status. It enquires what the evolution of the Aristotelian commentary tradition can tell us about the character of natural philosophy as a pedagogical tool, as a scientific enterprise, and as a background to modern scientific thought. In a unique attempt to cut old-fashioned historiographic divisions, it brings together scholars of ancient, medieval, Renaissance and seventeenth-century philosophy. (...) The book covers a remarkably broad range of topics: it starts with the first Greek commentators and ends with Leibniz. (shrink)

This article opens with a distinction between David Hockney's strong and weak theses. According to the strong thesis, in the period 1430-1860, optical tools were used in the production of paintings; according to the weak thesis, mirrors and lenses merely inspired their naturalistic look. It will be argued that while for the fifteenth and sixteenth centuries, there is little evidence in favor of the strong thesis, the case is different for the seventeenth century, for which the use of optical instruments (...) by painters is a documented fact. In this article, an early case is examined. The extant preparatory drawings of Gaspare Vanvitelli suggest that this cityscape painter relied on a camera obscura. But even here, the strong thesis must be tempered. The fact that several stages of artistic transformation separate the camera obscura projection from the finished painting undermines Hockney's analogy between optically assisted painting and 'naturalistic' photography.

In faith and practice, Pentecostals put emphasis on practical issues as well as spiritual experience in their theological understanding and doctrinal teachings. The Pentecostals take their doctrine from certain empirical events. One of the spiritual experiences often underlined is the baptism of the Holy Spirit. In interpreting the Book of Acts, Pentecostals tend to emphasise the theological character of the narratives and seldom their historical uniqueness. That is why Pentecostals stress the normative theological intent of the historical record for contemporary (...) Christian experience. This article therefore examines critically Pentecostal paradigm of the baptism of the Holy Spirit, deriving examples from the Acts of the Apostles. It is concluded that the practice of the baptism of the Holy Spirit carried out by Christians today, arguably, has no biblical basis. This is because, there is nowhere the Bible commands people to seek baptism in the Holy Spirit. The observation is that, all the events or experiences of Christians baptised in the Holy Spirit in Acts are not necessarily universal normative for every Christian and for this reason, there is no need to be dogmatic.Contribution: This article challenges the practice of the baptism of the Holy Spirit in church today. This study supports the fact that the baptism of the Holy Spirit is not a universal experience for every Christians and there is no need to be dogmatised. (shrink)
