This volume comprises Parts XIII XVI of the Speculum Divinorum et Quorundam Naturalium of Henricus Bate and includes "On Thinking and Happiness.""

This volume examines how the notion of law was transformed and reformulated during the Middle Ages. It focuses on encounters between ancient and local legal traditions and the three great revelation religions Judaism, Christianity, and Islam each of which understood the written word of God as law and formulated new cultures. The work thus furnishes interdisciplinary and intercultural insight into medieval legal discourse."

In the history of medieval philosophy and theology, Henry of Ghent ( 1293) occupies a prominent place. On the one hand, he is a critical reader of Thomas Aquinas, whose Aristotelianism he attempts to adjust by means of his so-called Augustinian Avicennianism; on the other hand, Henry can be considered a precursor of fourteenth-century thinkers, such as Duns Scotus and Ockham.

The papers collected in the volume, Henry of Ghent and the Transformation of Scholastic Thought, throw light on the particular renewal of the theological and philosophical tradition which Henry brought about and elucidate various aspects of his metaphysics and epistemology (e.g., truth, divine ideas, relation, certitude and wisdom), ethics (e.g., prudence, freedom, the role of the clergy), and theology (e.g., Trinity, creation, absolute and ordained power). The volume is completed with a comprehensive bibliography on Henry."
