This essay deals with Girolamo Fracastoro’s ensouled cosmology. His Homocentrica sive de stellis (1538), an astronomy of concentric spheres, was discussed by the Padua School of Aristotelians. Since the polemics over the immortality of the human soul, which had famously opposed Pomponazzi to Nifo, psychological discussions—including those about heavenly spheres’ souls—raised heated controversies. Fracastoro discussed the foundations of his homocentric planetary theory in a dialogue titled Fracastorius, sive de anima (1555). In a 1531 exchange with Gasparo Contarini, Fracastoro discussed celestial (...) physics, including problems linked to mathematical analysis of physical causation. Contarini expressed his doubts over Fracastoro’s lack of consideration of Aristotelian viewpoints on heavenly souls and intelligences. Fracastoro offered an account of cosmic animation in his later dialogue “On the Soul,” taking a different path than his Paduan teachers. He picked up the Platonic idea of the “world soul,” freely connecting it with Aristotelian views about the ensouled cosmos of concentric spheres, resulting in an eclectic composition of Platonic, Aristotelian, and Averroistic elements. Fracastoro grounded his renewed mathematical astronomy on an understanding of the cosmos as a living whole. His animated homocentric cosmos represented a development of Aristotelian premises and a step beyond this legacy. (shrink)

The focus of this paper is a fascinating but hitherto unstudied 1742 manuscript treatise by Johannes Daniel Schlichting (1705–1765) titled “Sapientiæ Problema” that contains something extremely rare in the mid-eighteenth century: a full-blown speculative cosmogony. As this article reveals, Schlichting developed a distinctive vital liquid matter in an effort to account for the generation of all natural bodies and combat the stamina-based theories that were dominant in his day. He hoped that his treatise would be published in the Philosophical Transactions (...) of the Royal Society, but an accompanying abridgment by the FRS Henry Baker (1698–1774) strongly implies that Schlichting’s speculative bent and desire to divulge causal explanations were unacceptable to the Englishman and generally ill-suited to the intellectual climate of mid-century England.

This essay proposes to discuss the manner in which Jan Baptista van Helmont helped to transform the Neoplatonic notions of vital spirit and of ferment by giving these notions an unambiguously chemical interpretation, thereby influencing the eventual naturalization of these ideas in the work of late seventeenth century chymists. This chemical interpretation of vital spirit and ferment forms part of Helmont’s hybrid ontology, which fuses a corpuscular conception of minima naturalia with a non-corporeal conception of semina rerum. For Helmont, chemical (...) alterations involve the minima as physical units but also depend upon ferments that are contained in the semina, which function as formative spiritual agents. Helmont’s nuanced ontology ultimately contributes to the development of modern corpuscularian theory by explaining many chemical reactions in fundamentally corpuscular terms, as the addition and subtraction of particles.

RESUMO O objetivo deste trabalho é indicar como a exploração estilística de Margaret Cavendish responde às particularidades do conceito de natureza dela, por exemplo, a tese de que a natureza é uma matéria viva, infinita, mutável e heterogênea. Primeiramente, mostrarei o modo pelo qual a autora está presente em seus escritos, como ela escreve de uma perspectiva de primeira pessoa sobre sua própria experiência e de quem ela é. Resumirei brevemente sua biografia e o contexto no qual ela praticou filosofia. (...) Dado que suas escolhas de estilo são bastante numerosas, apresentarei somente algumas poucas, entre as peculiaridades estilísticas dela. Em segundo lugar, desenvolverei uma visão geral do seu conceito de natureza, ao contrário do proposto pelas teorias mecanicistas de seu tempo. Esclarecerei que tal conceito é expresso adequadamente pela diversidade estilística à qual Cavendish se volta em suas investigações. ABSTRACT This paper aims at indicating how Margaret Cavendish's stylistic exploration answer to the particularities of her concept of nature, i.e. the thesis that nature is live, infinite, changing and heterogeneous matter. I will first show the way in which the author is present in her writings, as she writes from a first person perspective about her own experience and from who she is. I will briefly summarise her biography and the context in which she practiced philosophy. Given that her stylistic choices are quite numerous, I will only present a few of her stylistic particularities. Secondly, I will develop the general outline of her concept of nature, as opposed to the one proposed by the mechanistic theories of her time. I will make it clear that said concept is adequately expressed in the stylistic diversity to which Cavendish turns in her investigations. (shrink)

This essay deals with two seventeenth-century intellectuals, the Aristotelian philosopher at Padua, Cesare Cremonini, and the Jesuit controversist, Robert Bellarmine. In the years of the cosmological affair of 1616, both defended their cosmological conceptions by relying on the principle of authority. However, they embraced different sources of legitimation in matters of natural philosophy. While the Padua professor stick to (what he considered to be) the letter of Aristotle, basically a secular interpretation of his world conception, Cardinal and Inquisitor Bellarmine understood (...) the cosmos against a theological background. In particular, Bellarmine subordinated natural philosophy to exegesis and the authority of the Scriptures, and this allowed him to depart from Aristotle to some extent (for instance on the fluidity and possibly the corruptibility of the heavens). Yet, the two thinkers also shared the criticism of the major astronomical novelty of their time, namely the planetary system of Copernicus and his followers. But their objections rested on different worldviews and authorities (Aristotle and the Scriptures, respectively). Cremonini also supported a vision of celestial animation which was received with much preoccupation by religious authorities as they feared that his views might revive forms of astral worshipping. This essay discusses the manner in which Cremonini and Bellarmine received geocentrism and cosmology in very different, even opposite, manners, especially concerning the relation between natural philosophy and theology, and the reconcilability of cosmology with the Scriptures.
