140 Roger Bacon and the Hermetic Tradition in Medieval Science Roger Bacon and the Hermetic Tradition in Medieval Science GEORGE MOLLAND Roger Bacon would no more have wished to be called a Hermeticist than to be called a magician. For him magic was by its very nature bad, but this did not stop him from indulging beliefs and practices that bordered on the magical. Similarly, although he had no great or very favourable image of Hermes Trismegistus, his writings are infused with a spirit akin to what in a loose understanding of the term have been called Hermetic trends in Renaissance thought, and especially to the ` `Hermetic Tradition in Renaissance Science" .1 1 In exciting scholarship dating back some thirty years and more, a group of scholars, some closely associated with the Warburg Institute in London, demonstrated the vitality in Renaissance thought of quasi- magical traditions associated (sometimes rather remotely) with writings attributed to the supposed ancient Egyptian sage Hermes Trismegistus, and urged their importance for a proper historical assessment of the nascent Scientific Revolution.2 The impact made by these studies has produced the impression that "Hermetic" influences upon science were in essence a Renaissance phenomenon and had I The phrase is from Frances A. Yates' oft-cited article, The Hermetic Tradition in RenaissanceScience, in: Art, Science, and History in the Renaissance, ed. Charles S. Singleton, Baltimore 1968, 255-74, reprinted in F. A. Yates, Ideas and Ideals in the North EuropeanRenaissance.- Collected Essays, VolumeIII, London 1984, 227-46. 2 Among important writings in this genre, together with some more critical of it, I cite here: F.

The aim of the present article is to help redress the balance, and, while by no means denying Renaissance originality, to show that important ideas now often regarded as characteristically Renaissance, were very much alive in the Middle Ages. To this end I shall consider two facets of the work of Roger Bacon: the role that he ascribed to prisca auctoritas, or ancient authority, and his attempt to naturalise some apparently magical prac- tices by means of the doctrine of multiplication of species. 1. Prisca Auctoritas The role of things ancient-I adhere to this translation against Schmitt's preferred "venerable" -in Renaissance thought has been well summarised by the late Charles B. Schmitt in an article centred on Agonisto Steuco: The word priscus, probably best translated as "venerable", is one which recurs often in Steuco. He speaks of priscissaeculis, in former centuries, prisci philosophi, prisca philosophia,and firisci alone, referring to "the venerable philosophers and theologians". None of this is accidental. Truth flows from a single fountain, as it were, but is manifested in various forms. Moreover, the revelation of truth dates back to the most ancient times, to the prisca saecula,and we can find truth in the writings derived from this period. The wisdom of earliest times is then transmitted to the later centuries, truth and wisdom being as old as man himself.33 But, for all its other virtues, Schmitt's article paid scant attention to the Middle Ages. In like vein D.P. Walker, after discussing the for- tunes of what he called Ancient Theology in the early Christian period, continued, "When in the Renaissance the Ancient Theology was revived... "4 It is as if Renaissance scholars were launching a counter-attack to the "revolt of the medievalists"5 which would have antedated many of the Renaissance's more traditional virtues, and staking a claim for originality, or rather genuine rebirth, in this less familiar and prima facie rather "irrational" territory. But here again their claim must be modified, as I hope that the example of Roger Bacon will demonstrate. The phrase prisca auctoritas occurs in the opening passage of 3 Schmitt, PerennialPhilosophy, 520. 4 Walker, Ancient Theology,2. 5 To use the phrase of Wallace K. Ferguson, The Renaissancein Historical Thought, Cambridge, MA 1948, ch. 11. 141 .

  • THE INVENTION of ATOMIST ICONOGRAPHY 1. Introductory
    THE INVENTION OF ATOMIST ICONOGRAPHY Christoph Lüthy Center for Medieval and Renaissance Natural Philosophy University of Nijmegen1 1. Introductory Puzzlement For centuries now, particles of matter have invariably been depicted as globules. These glob- ules, representing very different entities of distant orders of magnitudes, have in turn be used as pictorial building blocks for a host of more complex structures such as atomic nuclei, mole- cules, crystals, gases, material surfaces, electrical currents or the double helixes of DNA. May- be it is because of the unsurpassable simplicity of the spherical form that the ubiquity of this type of representation appears to us so deceitfully self-explanatory. But in truth, the spherical shape of these various units of matter deserves nothing if not raised eyebrows.

  • Giordano Bruno and Michel De Montaigne
    Journal of Early Modern Studies, n. 6 (2017), pp. 157-181 DOI: http://dx.doi.org/10.13128/JEMS-2279-7149-20393 (Re)thinking Time: Giordano Bruno and Michel de Montaigne Rachel Ashcroft Durham University (<[email protected]>) Abstract The article seeks to illustrate how the theme of time may be a worthwhile starting point towards uncovering useful connections between the philosophy of Giordano Bruno and that of Michel de Montaigne. Firstly, a brief literature review will assess the admittedly small but promising criticism that has previously attempted to bring the two writers together. Subsequently, the article argues that time is a meaningful way to approach their texts. Specifically, time refers to the drama that arises between the material body, which generally exists within a so-called natural order of time, and the mind which is not tied to the present moment, and is free to contemplate both past and future time. The article argues that Bruno and Montaigne’s understanding of time in this manner leads them to question traditional representations of time, such as the common fear of death, in remarkably similar ways. This process will be illustrated through examples drawn from two chapters of the Essais and a dialogue from the Eroici furori, and will conclude by assessing the straightforward connections that have arisen between the two authors, as well as scope for further research in this area. Keywords: Giordano Bruno, Michel de Montaigne, Sixteenth Century, Time 1. Introduction In recent years, a small number of critics have attempted to establish significant biographical and intellectual connections between Giordano Bruno and Michel de Montaigne.

His brutal public execution and the fact that all of his books were placed on the Index of Prohibited Books are clear indications of just how controver- sial was his thought and polemical his personage. His trial is one of the most notorious in Italian history, along with that of Galileo, who, when confronted by the Inquisition, reacted meekly in comparison.1 Maurice Finocchiaro writes in his comparative article on the two trials, “If the trial of Galileo epitomizes the conflict between science and religion, then the trial of Bruno may be said to epitomize the clash between philosophy and religion.”2 Bruno’s clash with the Church came about early on in his ecclesias- tical career. Not long after being ordained in 1572, he found himself in disfavor for heretical ideas, and by 1576 had fled to avoid trial. He spent the greater part of his life traveling from center to center in Europe in search of patrons, publishers, and university employment, meeting with controversy almost everywhere he set foot; hence his imprisonment in Geneva and the dismissals from positions held in Marburg, Wittenberg, Prague, Helmstadt, Frankfurt, and Zurich.

  • Giordano Bruno and Plotinus on World Soul Dr
    Croatian philosophy and science in the European context between the 12th and 20th century Lecture – 12 February 2016 Giordano Bruno and Plotinus on World Soul Dr. Giannis Stamatellos (The American College of Greece) Abstract Giordano Bruno (1548-1600) and his Crotian contemporay Franciscus Patricius (1529- 1597) or Patrizzi (Frane Petrić) have been recognized as eminent figures of Reanaissance philosophy. Their innovative work incorporates not only elements of their contemporary intellectual tradition, but also embraces a reconsideration of antiquity through a novel interpretation of ancient Greek thought. Although Bruno and Patrizzi were contemporaries, the relation between the two philosophers is still unexamined in modern scholarship. In Bruno’s and Patrizzi’s explorations of a new intellectual and scientific world, pre- Platonic thinkers and Neoplatonic philosophers are some of their central sources of inspiration. From the Neoplatonic tradition, the philosopher who is highly acknowledged by Giordano Bruno is Plotinus (204-270 BCE); the “prince of Plato’s school” (princeps Plotinus). It is noteworthy that throughout Giordano Bruno’s work, his attitude towards Plotinus is always affirmative, with direct references to the Neoplatonist and key notions of the Enneads. In particular, Bruno refers by name to Plotinus twenty-six times with special mention in the works: The Shadow of Ideas (1582), Cause, Principle and Unity (1584), The Heroic Frenzies (1585), On Magic (1589-1590). Bruno discusses Plotinus’ metaphysics, psychology, cosmology and anthropology and especially Plotinus’ theories of intellect, soul, matter, memory and the nature of human being. In particular, Plotinus’ theory of the soul seems to be a key notion in Bruno’s thought.

    Filozofski vestnik Volume/Letnik XXV • Number/Številka 2 • 2004 • 25–50 GIORDANO BRUNO’S COPERNICAN DIAGRAMS Hilary Gatti The study of Giordano Bruno’s Copernicanism has a long and distinguished history, going back to the nineteenth century and continuing until the present day. It has involved a number of prestigious scholars, both histori- ans of science and historians of philosophy, such as Paul-Henri Michel, Alex- andre Koyré, Hélène Vedrine, Thomas Kuhn and Robert Westman, among many others1. This notable body of comment on Bruno as one of the major Copernican philosophers of the sixteenth century will be taken as given, and mention will be made of the details of his reading of the De revolutionibus only when necessary to the development of our subject. This intends to be a com- ment on the way in which Bruno attempted to pilot a recalcitrant sixteenth- century public, convinced of the falsity of the Copernican hypothesis except within a strictly mathematical formulation of it, towards a realist acceptance of the heliocentric principle, together with much else that Copernicus him- self would not have been prepared to accept. It was precisely this realist helio- 1 Serious consideration of Bruno’s Copernicanism starts with Domenico Berti’s pages in Copernico e le vicende del sistema copernicano in Italia, Paravia, Rome 1876, pp. 76–92.

  • Rhetoric and Philosophical Discourse in Giordano Bruno's Italian Dialogues
    Rhetoric and Philosophical Discourse in Giordano Bruno’s Italian Dialogues Eugenio Canone Italian Council of Research, ILIESI-CNR, Rome, Institute for the European Intellectual Lexicon and for History of Ideas Leen Spruit Philology, Linguistics, and Anthropology, University of Rome La Sapienza Abstract The Renaissance writers adapted the dialogue form to represent the cul- ture they were creating, using it for numerous subjects: philosophy, ethics, politics, religion, the arts, the study of language, and literature. The dialogue was an appro- priate form for works which are at once serious, ironical, and critical. Giordano Bruno’s Italian dialogues are a case in point. This essay scrutinizes the structure of these works, with special attention to the role of the interlocutors in his rhetoric. During his sojourn in England (1583–85), Giordano Bruno (1548–1600) published six Italian dialogues. Since the end of the nineteenth century, these works have been the object of scholarly research. The dialogues have been studied not only as philosophical works but also—since the second 1. In 1584 Bruno published La cena de le Ceneri, De la causa, principio et uno, De l’infinito, universo e mondi, and Spaccio de la bestia trionfante; in 1585 Cabala del cavallo pegaseo and De gli eroici furori. Recently, a reprint of the original editions appeared; see Bruno 1999a. All dialogues were published in London with John Charlewood; the title pages display mere fictitious indica- tions of places and editors. The edition we used was Bruno 2002a. For the titles we use the following translations: The Ash Wednesday Supper (Bruno 1995 [1977]), On Cause, Principle, and Unity (Bruno 1998), On the Infinite Universe and Worlds (Bruno 1950), The Expulsion of the Trium- phant Beast (Bruno 1992 [1964]), The Cabala of Pegasus (Bruno 2002b), and The Heroic Frenzies (Bruno 1964).

Leibniz invented machines and developed the calculus. He was a force for peace, and industrial and cultural development through his work as a diplomat and correspondence with leaders across Europe, and in Russia and China. With Leibniz, science became a means for improving human living conditions. For Leibniz, science must begin with the “God’s eye view” and begin with an understanding of how the Creator would have designed the universe. Accordingly, Leibniz advocated the a priori method of scientific discovery, including the use of intellectual constructions or artifices. He defended the usefulness and success of these methods against detractors. While cognizant of Baconian empiricism, Leibniz found that an unbalanced emphasis on experiment left the investigator short of conclusions on efficient causes.
