The Scientific Revolution and the Origins of Modern Science Third edition John Henry Magic and the Origins of Modern Science 4 Magic and the Origins of terms. Success as a natural magician depended upon a profound knowledge of bodies, and how they act upon one another, in Modern Science order to bring about the desired outcome [53; 146; 313]. Repeat edly we see Renaissance natural magicians insisting that their form of magic depends upon nothing more than knowledge of nature, so much so that one recent historian has suggested that we should designate this kind of thinking as 'Renaissance natural ism' to distinguish it from what he thinks of as real magic [156]. Further important sources of the empiricism of the Scientific In a very real sense, however, the separation of the natural Revolution were to be found in the magical tradition, and these istic elements from other aspects of magic was just what was influences can be seen at work in a number of areas. They deserve accomplished during the Scientific Revolution. The history of separate consideration here, however, because they have gener magic since the eighteenth century has been the history of what ated considerable historiographical debate [304; 54; 216; 221; was left to that tradition after major elements of natural magic 146]. A number of historians of science have refused to accept had been absorbed into natural philosophy [153; 150: Chs 5, that something which they see as so irrational could have had 6]. Moreover, for us magic deals with the supernatural, but any impact whatsoever upon the supremely rational pursuit of for early modern thinkers magic relied for its effects upon the science. Their arguments seem to be based on mere prejudice, manipulation of natural objects and processes. For them only or a failure to understand the richness and complexity of the God could bring about supernatural events.

The flourishing of magic hidden natural powers of objects to bring about desired events certainly owed a great deal to the rediscovery of Ancient Neopla [36; 53; 156; 150: Ch. 7]. The reason why natural magic has tonic writings, which included the writings attributed to Hermes disappeared from our conception of magic is precisely because Trismegistus (although it is now generally agreed that the claims of the most fundamental aspects of the tradition have now been Frances Yatesand her followersabout the influence of the so-called absorbed into the scientific world-view. Or, to put it another Hermetic tradition have been greatly exaggerated [54]), but it is way, the scientific world-view developed, at least in part, out of a now clear that it also owed much to new trends within Renaissance wedding of natural philosophy with the pragmatic and empiri Aristotelianism. The principles upon which the medieval theory of cal tradition of natural magic [146,153]. magical interactions was based derived, inevitably, from scholastic The pragmatism of magic is obvious. The aim of the magus Aristotelianism. During the Renaissance, a number of Aristotelian is always to bring about some desired outcome, either for his philosophers, notably Giovanni Pico della Mirandola (1463-94) own benefit or that of a patron or client [54; 83; 84; 87; 88; and Pietro Pomponazzi (1462-1525), refined the more naturalis 139; 294; 216; 287]. The empiricism of magic may seem more tic aspects of the magical tradition (in which magical effects were surprising to us.

In other words, the numbers Fludd used were correct wayto understand the natural world can be seen in the fact imposed upon the heavens by his own fancy, but Kepler used that, surprising though it may seem, technology was inextricably only numbers which can be seen to be built into the actual system linked with magic throughout the Middle Ages and the Renais [54; 95; 72; 131]. Kepler's distancing of himself from Fludd in sance [83; 84; 253; 153]. This does not mean that the uninitiated this way should not be seen as a rejection of magical traditions, believed machines were worked by inner demons (remember, however, but as a reaffirmation of sound natural magic. When magic was believed to work by natural means). The elaboration Francis Bacon wrote that 'There is a great difference between the of mechanical contrivances to produce marvellous effects was Idols of the human mind and the Ideas of the divine', he might simply regarded as the exploitation of the occult, but natural, have spoken for Kepler, and it is clear from what he went on powers of things and therefore the province of the magician [83; to say, that Bacon nonetheless believed that God's Creation bore 296]. Moreover, because of the close links between mechanics and signs of its significance and usefulness for mankind: 'That is to mathematics, this kind of exploitation of machinery was often say,between certain empty dogmas, and the true signatures and called 'mathematical magic'. So magic also became associated marks set upon the works of creation as they are found in nature' with the mathematical approach to understanding the physical [quoted in 8: 323; 150]. world [84; 146; 153; 42; 91]. Indeed, associations between magic Accordingly, it is important to note that Kepler's determina and mathematics were so commonplace that there was a notice tion of celestial harmonies, using Tycho Brahe's extremely accu able attempt by numerous mathematicians to dissociate them rate observations, enabled him to prove to his own satisfaction selves from magic as they began to rise in social status. Magic had that there are only six planets because God created the universe always been condemned by the Church because of its demono in accordance with a 'geometrical archetype'. God separated the logical associations, and it was always distrusted by the common planets from one another, Kepler became convinced, by nesting people who were all too aware of the fraudulent use of magic. It them alternately with each of the five so-called Platonic solids. The became important, therefore, for the new breed of mathematical point about these solids is that the principles of Euclidean geom practitioners to distinguish themselves from the wrong kinds of etry establish that they are the only three-dimensional bodies magicians [219; 330]. of their kind. No other closed solid can be made with all faces The process was by no means simply a wholesale rejection of the same. Thus, when God inscribed a cube inside the sphere of anything that smacked of magic. Many thinkers at this time still Saturn, touching the sphere at its eight corners, and then used sawmagic as a noble and worthwhile pursuit and their concern was that cube to demarcate the sphere of Jupiter, so that that sphere with corruptions or debasements of it.Tohannes Kepler, consum touched each face of the cube, and proceeded similarly with the mate mathematical astronomer that he was, can also be seen to tetrahedron between Jupiter and Mars and so on, the creation of have been deeply affected by the magical tradition of numerol planets had to stop with six, since there were no remaining solids ogy. It is well known that a major stimulus to his work in cosmol which God could use to determine where to place the next planet ogy was his attempt to answer the question of why there were [95; 185; 148]. Kepler's use of mathematics was very different only six planets. This is not a scientific question: it seeks to under from Fludd's, but it can hardly be said that it was not steeped in stand what is so significant about the number six that God should the Neoplatonic magical tradition. have used it, and no other number, to be the number of planets.
