Fortunio Liceti Against Marsilio Ficino on the World-Soul and the Origin of Life CHAPTER FIVE FORTUNIO LICETI AGAINST MARSILIO FICINO ON THE WORLD-SOUL AND THE ORIGIN OF LIFE 1. Introduction The name of the Florentine Platonist Marsilio Ficino has surfaced several times in the previous chapters. To evaluate the impact of his philosophy on early modern science, it is important to consider the application of his metaphysical ideas to natural questions in the sixteenth and seven- teenth centuries. In spite of some recent studies devoted to cosmology, the fijields of matter theory and life sciences remain largely unexplored by specialists of Ficino. One of the most crucial problems of these domains is without doubt the origin of life. In this regard, the question of sponta- neous generation or “abiogenesis,” that is, the birth of living beings from lifeless matter, is interesting since it illustrates the cause of matter’s activ- ity and its animation or ensoulment.1 Ficino actually used this phenom- enon as crucial evidence toward his thesis on universal animation. Thus the present chapter will focus on his theory of spontaneous generation. For this purpose, the criticism formulated by Fortunio Liceti (1577–1657), a Paduan professor of philosophy and a friend of Galileo Galilei (1564– 1642), seems to serve as the best guide.2 In his work On the Spontaneous 1 See Edmund O. von Lippmann, Urzeugung und Lebenskraft: Zur Geschichte dieser Probleme von den ältesten Zeiten an bis zu den Anfängen des 20.

In Italy too, Liceti’s theory was well known, being literally absorbed into the writings of Athanasius Kircher, who pro- voked intense debates on the issue all over Europe.4 From antiquity, the problem of spontaneous generation was often linked to the idea of universal animation. To explain its mechanism, Aris- totle argued in his Generation of Animals, 3.11, that the pneuma resides in the earth’s humidity and conveys a “soul-heat” (thermotês psuchikê) every- where in the world, so that “all things are in a sense full of soul.”5 One of his most successful Greek commentators, Themistius, then connected the Platonic idea of the World-Soul to spontaneous generation more explic- itly. His theory was widely difffused through a quotation made by Aver- roes in his Long Commentary on Aristotle’s Metaphysics, 12.18.6 Averroes’s “L’opera medica di Fortunio Liceti (nota preliminari),” in Atti del XX° congresso nazionale di storia della medicina (Rome, 1965), 235–44; Marilena Marangio, “I problemi della scienza nel carteggio Liceti-Galilei,” Bollettino di storia della fijilosofijia 1 (1973), 333–50.

  • A New Vision of the Senses in the Work of Galileo Galilei
    Perception, 2008, volume 37, pages 1312 ^ 1340 doi:10.1068/p6011 Galileo's eye: A new vision of the senses in the work of Galileo Galilei Marco Piccolino Dipartimento di Biologia, Universita© di Ferrara, I 44100 Ferrara, Italy; e-mail: [email protected] Nicholas J Wade University of Dundee, Dundee DD1 4HN, Scotland, UK Received 4 December 2007 Abstract. Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astron- omy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a different path from the main stream of the then contemporary studies in the field; these were concerned with the dioptrics and anatomy of the eye, as elaborated mainly by Johannes Kepler and Christoph Scheiner. Galileo was more concerned with the phenomenology rather than with the mechanisms of the visual process. His general interest in the senses was psychological and philosophical; it reflected the fallacies and limits of the senses and the ways in which scientific knowledge of the world could be gathered from potentially deceptive appearances. Galileo's innovative conception of the relation between the senses and external reality contrasted with the classical tradition dominated by Aristotle; it paved the way for the modern understanding of sensory processing, culminating two centuries later in Johannes Mu« ller's elaboration of the doctrine of specific nerve energies and in Helmholtz's general theory of perception.

  • Galileo in Early Modern Denmark, 1600-1650
    1 Galileo in early modern Denmark, 1600-1650 Helge Kragh Abstract: The scientific revolution in the first half of the seventeenth century, pioneered by figures such as Harvey, Galileo, Gassendi, Kepler and Descartes, was disseminated to the northernmost countries in Europe with considerable delay. In this essay I examine how and when Galileo’s new ideas in physics and astronomy became known in Denmark, and I compare the reception with the one in Sweden. It turns out that Galileo was almost exclusively known for his sensational use of the telescope to unravel the secrets of the heavens, meaning that he was predominantly seen as an astronomical innovator and advocate of the Copernican world system. Danish astronomy at the time was however based on Tycho Brahe’s view of the universe and therefore hostile to Copernican and, by implication, Galilean cosmology. Although Galileo’s telescope attracted much attention, it took about thirty years until a Danish astronomer actually used the instrument for observations. By the 1640s Galileo was generally admired for his astronomical discoveries, but no one in Denmark drew the consequence that the dogma of the central Earth, a fundamental feature of the Tychonian world picture, was therefore incorrect. 1. Introduction In the early 1940s the Swedish scholar Henrik Sandblad (1912-1992), later a professor of history of science and ideas at the University of Gothenburg, published a series of works in which he examined in detail the reception of Copernicanism in Sweden [Sandblad 1943; Sandblad 1944-1945]. Apart from a later summary account [Sandblad 1972], this investigation was published in Swedish and hence not accessible to most readers outside Scandinavia.

  • Introduction
    Introduction 1Aristotle Accordingtothe Oxford English Dictionary (online version), in contemporary English usagethe word ‘nutrition’ carries four meanings: 1. The action or process of supplying,orofreceiving,nourishment or food. 2. That which nourishes; food,nourishment. 3. The state or condition of being (well or badly) nourished;aperson’sstate of health considered as aresultorindicator of (good or bad) nourishment. 4. The branch of science that deals with nutrition (sense 1)and nutrients, esp. in humans;the studyoffood and diet. In light of the abovedefinitions, ‘nutrition’ seems an appropriate English render- ing for the Greek words τροφή or τὸ τρέφειν/τρέφεσθαι,which are used by au- thors of the 5th and 4th centuries BCE to refer to processes, activities or functions related to nourishment,oreventokinds of food or nutriment that are able to nourish or procuresustenance. The term θρέψις is not attested before the 2nd cen- tury CE. In Galen θρέψις is acknowledgedasone of the three main activities (ἐνέργειαι)ofnature – the othertwo being growth and generation (De facultati- bus naturalibus I,5, K. II,10). Specifically, rendering 4resonates with what in Hippocratic texts is some- times referredtoasdietetics, that is, that part of the medicalart (and not science) which dealswith diet (δίαιτα). The gradual development of dietetics into acor- nerstone of medicine wasset off by medical ideas of that time which are closely akin to rendering3,most notablythe belief that aperson’sstate of health de- pends heavilyonthe food (s)he consumes.Inone of its two main meanings (the other being ‘rearing’, ‘bringingup’), τὸ τρέφειν,apart from the act of nour- ishing,refers to the substances thatare able to nourish (so, rendering 2).Now concerning nutrition as abodilyfunctionrelated to aset of individual physiolog- ical activities of certain bodyparts, Aristotle seems to deserve, at least to acer- tain degree, credit for being the first to explicitlymake such aprogress (cf.

  • Galileo E Liceti, Ovvero Genio E Mediocrità
    LA COSCIENZA: TRA FILOSOFIA E NEUROSCIENZE 239 GALILEO E LICETI, OVVERO GENIO E MEDIOCRITÀ MARIAPIERA MARENZANA già Docente di Lettere presso l’Accademia Nazionale di Danza, Roma 1. Fortunio Liceti Fortunio Liceti, chi era costui? Era, proprio come il Carneade di manzoniana memoria, un filosofo aristotelico, il quale tuttavia, a differenza dell’antico Carneade, ebbe la ventura di essere contemporaneo di Galileo e suo corrispondente. A questo egli deve, assai più che alla vasta cultura libresca e alla iperprolifica attività di scrittore, l’aver consegnato il suo nome alla storia. Emerge infatti, dalla trentennale corrispondenza tra i due, oltre al ritratto a tutto tondo di due personalità tanto diverse, un quadro vivace dei rapporti conflittuali e drammatici fra la cultura tradizionale fondata su «un mondo di carta» e quella nuova, basata sull’esperimento e sul dubbio. C’è inoltre molto Liceti ritratto nel Simplicio del Dialogo, e anche nel più rispettabile Simplicio dei Discorsi, ed è da una polemica con Liceti che ha origine l’ultima opera scientifica di Galileo. Sullo sfondo dell’epistolario sono le vicende biografiche dei due corrispondenti, i principali allievi dello scienziato pisano, le dispute accademiche, i contatti culturali in Italia e in Europa, l’ombra minacciosa dell’Inquisizione, la peste, ma anche aspetti minuti della vita quotidiana del ‘600. Liceti deve il suo nome, Fortunio, alla nascita prematura e avventurosa avvenuta, nel 1577, su una nave sbattuta da una tempesta nel tratto di mare fra Recco e Rapallo; il padre, medico, avrebbe assicurato la sopravvivenza del bimbo ponendolo in una scatola tenuta in caldo. Il fortunoso ingresso nel mondo, e i racconti che certamente gliene vennero fatti, influirono senza dubbio sul gusto per il meraviglioso e l’insolito che avrebbe caratterizzato la vita di Liceti.

    Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) De Monstruorum Causis, Natura et Differentiis (On the Reasons, Nature and Differences of Monsters) (1616), by Fortunio Liceti [1] By: Guerrero, Anna Keywords: monsters [2] De monstruorum [3] Fortunio Liceti [4] birth abnormalities [5] supernatural [6] In 1616 in Padua, Italy, Fortunio Liceti, a professor of natural philosophy and medicine, wrote and published the first edition of De Monstruorum Causis, Natura et Differentiis (On the Reasons, Nature, and Differences of Monsters), hereafterD e monstruorum. In De monstruorum, Liceti chronologically documented cases of human and animal monsters from antiquity to the seventeenth century. During the seventeenth century, many people considered such monsters as frightening signs of evil cursed by spiritual or supernatural entities. Liceti categorized monsters based on their potential causes, several of which he claimed were unrelated to the supernatural. Historians later noted that some documented monsters were infants with birth defects [7]. In De monstruorum, Liceti elevated the status of monsters to potential subjects of scientific inquiry and provided an early model for the study of birth defects [7], a field later called teratology [8]. In the seventeenth century, when Liceti publishedD e monstruorum, many people classified infants with birth defects [7] as monsters. According to historians Lawrence Longo and Lawrence Reynolds, humans [9] have a fascination with abnormal body form, depicting anatomical anomalies on ancient rock carvings. By the late Middle Ages, people understood physical abnormalities in a religious context. Therefore, during the fifteenth, sixteenth, and seventeenth centuries, many people considered monsters, or those with physical abnormalities, to be signs of evil caused by supernatural beings.
