Few figures of the Middle Ages command the attention of so many modern disciplines as Robert Grosseteste (c. 1170-1253). Theology, Philosophy, History, and Science are all areas which his life and thought continue to have significance and to inspire re-interpretation. Accompanied by a series of original commentaries, this new edition of Grosseteste's work, with English translation, draws together the perspectives of modern scientists and medieval specialists. Volume I of a six volume series, Knowing and Speaking presents two of the earliest (...) of Grosseteste's works, the treatises On the Liberal Arts and On the Generation of Sounds. These are accompanied by a significant Middle English treatise on the Seven Liberal Arts whose anonymous fifteenth-century author translated and excerpted passages from Grosseteste's treatises in a re-imagining of their structure and function.0Each work is treated separately within the volume, which is constructed in three parts. On the Liberal Arts sets Grosseteste's thoughts on the arts subjects and emphasises moral concerns about the purpose of learning. On the Generation of Sounds builds on the theories and statements of On the Liberal Arts in connection to the production of sound, elaborating the earlier position, relating the generation of sounds to human vocal and speech production.

This dissertation studies Grosseteste's attempt in his De libero arbitrio to develop a theory of non-temporal modality which severs possibility and changeability. It consists in close philosophical analysis of Grosseteste's views, based on new editions and translations of De libero arbitrio, De scientia Dei, and De veritate propositionis contained in the Appendices. ;After studying the theories of modality proposed by Boethius, Abelard, and twelfth century logic texts, together with the logico-linguistic framework thirteenth century writers drew from them, I examine the (...) basic assumptions and motivations of Grosseteste's discussion: the notions of sentences and dicta, time-variable truth-value, the notion of power, the problem of reconciling divine knowledge and human free will. ;I identify two main modal theories in Grosseteste, one linking possibility with changeability of truth-value and bearing similarities with as well as important differences from the theories of the twelfth century logicians; the other presented as a reaction to this theory and, in particular, to its unusual claim that true sentences about future contingents are necessary. I attempt to make sense of this by a reconstruction of the theory, making use of the notion of dense time. ;I then investigate in detail Grosseteste's theory of the eternal truths, with an eye to its relation to his theories of modality. I show that Grosseteste's sophisticated theory is not a theory of modality; the theory is seen, nonetheless, to highlight obscurities in Grosseteste's account of non-temporal modality. ;The account of non-temporal modality rests on the notion of a dictim's eternal power; these powers are reduced to God's eternal powers. I critically examine Grosseteste's defense of the idea of divine power, highlighting the difficulties he viewed the notion of the actualizability of a power and of its priority to act as posing. His views on these matters are compared with those of Scotus. ;I investigate the theory of non-temporal modality erected on this basis and, in particular, its reduction to divine powers, the adequacy of the strategy, and Grosseteste's use of the theory to solve the problem divine knowledge poses for free will.
