Robert Grosseteste's Conclusiones and the Commentary on the Posterior Analytics
AbstractThis article examines the nature of Robert Grosseteste's commentary on Aristotle's Posterior Analytics with particular reference to his “conclusions” (conclusiones). It is argued (using book 1, chapter 2, of the commentary as a case study) that the simple demonstrative appearance of the commentary, which is very much the result of the 64 conclusions, is in part an illusion. Thus, the exposition in the commentary is not simply based on the strict principles of the Posterior Analytics and on the proof-procedures of Euclidean geometry; rather the commentary is a complicated mixture of different elements of twelfth-century texts and the scholarship of Grosseteste's day.
