Albert of Saxony, master of Arts at Paris from 1351 until 1361/62, has left two commentaries on the Physics of Aristotle. Since he was well aware of the tradition, his writings may serve for an analysis of the transmision of ideas from the ancient and Arabic philosophers into the fourteenth century. In this paper, this is exemplified by the problems of place and space, especially by those of the definition of place and of the immobility of place, of natural place (...) and of the location of the last and outermost sphere. As a result, four modes emerge how an author of the fourteenth century may have been influenced by tradition. Ancient Greek or Pre-Socratic philosophers were mainly known through Aristotle, and thus their opinions were mostly refuted; the same holds true for later ancient or Arabic authors known through the commentaries of Averroes; the influence of the authors of the thirteenth century was present though their texts may not have been directly consulted; and, finally, the contemporary authors were known, but nearly never quoted. Thus, though there was a line of tradition from Aristotle into the fourteenth century, there was also room for proper solutions. (shrink)

Experience played a key role in the natural science of the later Middle Ages. Both the terms “experience” and “experiment” can be found in medieval texts. However, the latter was mainly used as a synonym and there is only a slight allusion to the concept of experiments in the modern sense. In their arguments, medieval authors rather referred to day-to-day experience, to phenomena which were evident from simple observation. The medieval Latin meaning of expertus (or its close equivalent experimentator) was (...) thus closely related to the notion of everyday experience. An expert was someone who had a wide experience of natural phenomena and who always sought to extend his knowledge. During the later Middle Ages, this aspect slowly gained in importance (despite the fact that written authorities and the textbooks of natural philosophy remained dominant), thus opening up new ways of thinking, which finally led to the Scientific Revolution.
