Cesare Pastorino, New perspectives on the investigation of specific weight in the sixteeenth century


Received accounts on the history of the determination of specific weights of substances in the early modern period have mostly focused on the antecedents of modern disciplinary concepts and methodologies. In particular, this has meant that much attention has been devoted to experimentation and measurements adopting the hydrostatic methods based on the principle of Archimedes. However, the use of these methods was not as self-evident and widespread as the modern assessments suggest. In this presentation I will show how the investigation of specific weights in the sixteenth century had a larger scope than the hydrostatic Archimedean tradition, and that its proper history still needs to be written.

What is enactment? The interplay between trials and hypotheses.

Dana Jalobeanu, Enactment and the interplay between ‘data’ and research hypotheses: the „middle region” of the air

Abstract: In the beginning of the second part of the Novum organum Bacon gives us an example which is intended to illustrate the steps of his method of inquiry. Chief among these steps is the operation of filling the tables: tables of presence, absence and variation. However, Bacon’s tables of heat are not really filled in. They contain open-ended questions, gaps, suggestions and ideas of complex experimental inquiries. In a way, they are hardly “tables” and more like lists recorded as something one might want to still work on, in the future. In this paper I am addressing a deceptively simple question: how are these tables supposed to be filled in? Like Bacon, I am also working on a single example: the issue of heat in the middle-region of the air which appears in his table of absence. I will show how Bacon’s followers have pursued this issue in their attempts to fill in the table. And what a difficult task it has proven to be. And I will try to show that thinking of experimental work in terms of deciphering, enactment and recording/encoding can throw an interesting light on these difficult matters.

Dana Jalobeanu and Oana Matei, Spiritual Technologies: Cider-Making and Natural Philosophy in Early Modern England


Cider making does not strike one as much of a philosophical enterprise. However, in England, in the second part of the seventeenth-century, many natural philosophers were actively involved in it. Among them, a consistent bunch of members of the Royal Society, organized in an agricultural or Georgical Committee. Working on plans previously laid out by Samuel Hartlib and his friends, natural philosophers such as John Beale, Ralph Austen and John Evelyn, practitioners such as John Worlidge or William Lawson, conceived a grand-scale project of turning England into a paradise of orchards, thus replacing wine and beer with cider. This paper investigates the philosophical premises and methodological underpinning of this enterprise, showing that cider-making developed as a branch of applied Baconian science. We show that the grand-scale enterprise of cider making shared a background theory of Baconian inspiration and was conceived in terms of Bacon’s rules and methods of experimenting and collaborative data-sharing. With this Baconian theoretical and methodological framework, naturalists involved in this enterprise selected and tried old recipes, experimented with new ones and turned cider-making into an early modern technology. Central to this technology was the idea that, in the process of cider-making, the naturalist manipulates the living spirits of the vegetal world, encapsulating them in a bottle. In terms of methods and practices, the spiritual technology of cider-making drew on old and new recipes, turning them into trials and experiments, by applying rules and principles of testing, corroborating and collaboration borrowed from other Baconian natural and experimental histories.

Practical exegetics: a discussion with Jennifer Rampling

We will be discussing the notion of “practical exegetics” starting from Chapters 2 and 3 of Jennifer Rampling’s book, “The Experimental Fire.” The Experimental Fire. University of Chicago Press, 2020.

The `practical exegetics’ is an important concept in Rampling’s book. It denominates a complex methodology of reading and interpreting alchemical texts which effaces many of the differences one can imagine between the practitioner of the medieval alchemy and the historian trying to make sense of the old texts.

Oana Matei, Vegetation, Fermentation, and Digestion. Nehemiah Grew’s conceptual vocabulary in The Anatomy of Plants

Grew’s Anatomy of Plants presents the microscopic structure, organization and functioning of plants. Apart from that, Grew’s research work allowed him to question and investigate the fundamental process of vegetation using microscopic lenses and to delve into its multiple stages of filtration, separation and mixture. This presentation focuses on Grew’s use of vocabulary in describing the processes through which a seed becomes a mature plant. I will try to delineate what Grew understood by vegetation, fermentation and digestion. I will also try to capture the existing relation between these concepts and to identify how Grew used them in different contexts.

Dana Jalobeanu, Experimenting with artificial life: Francis Bacon’s Historia et inquisitio de animato et inanimato

Bacon, Historia de animato et inanimato (BN manuscript, Dupuy collection)

Among the unfinished projects one can find among Francis Bacon’s posthumous and fragmentary works there is an extremely interesting and under-investigated short fragment of a projected history of “animated” and “unanimated” beings. It is called Historia et inquisitio de animato et inanimato. The very title sets this fragment aside from Bacon’s other natural and experimental histories. It is not merely a natural history, but a more advanced, philosophically informed experimental inquiry (the meaning of Bacon’s term inquisitio) into the nature of living beings. And chief among its concern is an attempt to experiment with the production of life itself. But what does it mean to experiment with “artificial life”? It is what I attempt to answer in this presentation.
