By William A. Wallace

William Wallace brings a good intelligence and years of mirrored image to teach how the idea that of causal rationalization can give a contribution to the cumulative development of data in technological know-how. Wallace's procedure is ancient in addition to analytical, and is composed in a cautious and hugely unique research of the way the hunt for explanations has supplied a paradigm of clinical strategy from its origins within the heart a while as much as the current day. the 1st of 2 volumes poses the modern query and strains its beginning again to the 'Posterior Analytics' of Aristotle. the writer then concentrates on medieval technological know-how to record the impression of the 'Analytics' on the universities of Oxford, Paris, and Padua from the thirteenth to the sixteenth centuries, comparing within the procedure the rival claims of historians of technology as to the significance of those facilities for the genesis of the experimental strategy. the quantity concludes with a learn of the founders of recent technological know-how from William Gilbert to Isaac Newton, displaying the amazing use they made from causal strategies of their personal now classical contributions.

Sample text

But the efficacy of the efficient cause and of the material cannot be known without the great power of mathematics, even as the effects produced cannot be known without it. There are then these three, the efficient cause, the matter, and the effect. In celestial things there is a reCiprocal influence of forces, as of light and other agents, and a change takes place in them, without however any tendency toward their destruction. And so it can be shown that nothing within the range of things can be known without the power of geometry.

Like Aristotle, Grosseteste explains the relationship of particular causes to demonstration when comparing causal definitions and explaining how such definitions may be related to one another through the process of demonstration. oo In this context he explains that a definition based on the formal cause may be used to demonstrate a definition based on the material cause, and that if the definition contains both the fannal and the material causes it is equivalent to a demonstration and differs only in the way in which the terms are ar- 44 Medieval Science at Oxford ranged.

This is not an Aristotelian teaching, of course, but Grosseteste has already admitted this and is attempting to go beyond the text on which he is commenting. The case of the moon's sphericity is treated by Grosseteste in similar fashion. 25 His quia demonstration, based on the generally accepted geometry of the De sphaera, again involves the visual pyramid theory of sight, and the analysis is carried out in terms of the pyramid subtended at the eye by Medieval Science at Oxford the moon's surface and another, larger pyramid whose base is the curve of the illurnined portion of the moon, which curve he calls a circle "causa brevitatw," 26 His proof consists in showing that the moon's phases can effectively be accounted for by the rotation of the "circle" which is the base of this larger pyramid around the moon's disc (itself the base of the smaller pyramid), and that granted the conditions of the moon's illumination by the sun in conjunction.
