This paper analyses the questions on the science of the soul and on the immortality of the soul in two commentaries on Aristotle’s De anima that subsist in the manuscripts of the teaching of philosophy in Coimbra in the sixteenth-century. The paper shows that the positions of the two commentators – Petrus Fonsecae (attr.) and Christophorus Gilli – are in total opposition, concerning either the commentary tradition on Aristotle’s De anima or the theories on the soul they assume. Focused (...) on unpublished and less studied sources this research brings to light some innovative aspects of the teaching of philosophy in Coimbra. We thus suggest that the manuscript sources of the period be reassessed and studied in comparison to the published works. (shrink)

Drawing on archival material in Utrecht and Rotterdam, we examine the geophysical surveys of Indonesia and Brazil carried out by Elie van Rijckevorsel during the period 1870 to 1890. We pay special attention to the complex interactions among university academics, government administrators and ministers of state, and private, ‘gentlemanly’ specialists. Making an appearance, in addition to Van Rijckevorsel, are the Utrecht polymath Christophorus Hendricus Diedericus Buys Ballot , the colonial and metropolitan astronomer Jean Abraham Chrétien Oudemans , colonial geophysicist (...) Pieter Adriaan Bergsma , French-Brazilian astronomer Emmanuel Liais , Colonial Minister Isaac Dignus Fransen van de Putte , and others. The decision of Van Rijckevorsel, an independently wealthy man of learning, to carry out a magnetic survey of the Malay archipelago spurred colonial authorities at The Hague to endow the finest geomagnetic observatory in the tropics. Van Rijckevorsel's interactions with academia and government suggest the extent to which wealthy Dutch patricians readily accepted government patronage for their scientific undertakings. A late-nineteenth-century Dutch ‘gentleman of science’ is seen to differ rather widely from his English counterpart of an earlier generation. An appendix reproduces, in English translation, correspondence from the early 1870s. (shrink)

Vydání Galileova Hvězdného posla vyvolalo okamžitou reakci mnoha evropských učenců, s jednou důležitou výjimkou, kterou tvořili jezuitští matematici Římské koleje pod vedením uznávaného matematika Christophora Clavia. Cílem článku je prozkoumat možné důvody opožděné reakce římských jezuitů, kteří se k nebeským objevům vyjádřili více než rok po vydání Galileovy knihy. Existují důkazy nasvědčující tomu, že i když byli římští matematici nakloněni uznání novinek odhalených teleskopem, nástrojem, který ještě musel dokázat svou důvěryhodnost, byli omezeni přísnými pravidly, která měla za úkol udržet jednotu (...) jezuitského řádu.
