"An Enquiry Concerning Human Understanding" is a book by David Hume created as a revision of an earlier work, Hume's "A Treatise of Human Nature". The argument of the Enquiry proceeds by a series of incremental steps, separated into chapters which logically succeed one another. After expounding his epistemology, Hume explains how to apply his principles to specific topics. This book has proven highly influential, both in the years that would immediately follow and today. Immanuel Kant points to it as the book which woke him from his self-described "dogmatic slumber."

The medieval Christian West's most radical practitioners of a Neoplatonic, negative theology with a mystical focus are John Scottus Eriugena, Meister Eckhart and Nicholas Cusanus. All three mastered what Cusanus described as docta ignorantia: reflecting on their awareness that they could know neither God nor the human mind, they worked out endlessly varied attempts to express what cannot be known. Following Pseudo-Dionysius the Areopagite, they sought to name God with symbolic expressions whose negation leads into mystical theology. For within their Neoplatonic dialectic, negation moves beyond reason and its finite distinctions to intellect, where opposites coincide and a vision of God's infinite unity becomes possible. In these papers Duclow views these thinkers' efforts through the lens of contemporary philosophical hermeneutics. He highlights the interplay of creativity, symbolic expression and language, interpretation and silence as Eriugena, Eckhart and Cusanus comment on the mind's work in naming God. This work itself becomes mystical theology when negation opens into a silent awareness of God's presence, from which the Word once again 'speaks' within the mind - and renews the process of creating and interpreting symbols. Comparative studies with Gregory of Nyssa, Pseudo-Dionysius, Anselm and Hadewijch suggest the book's wider implications for medieval philosophy and theology.

The Decisive Treatise is perhaps the most controversial work of Averroes (Ibn Rushd, 1126-1198) and belongs to a trilogy which boldly represent the philosophical contribution to Islamic theology of this famous Andalusian commentator on Aristotle. The Decisive Treatise is a fatwa (a legal opinion) that the judge, Averroes, promulgated for his fellow Malikite jurists in order to demonstrate that the study of philosophy is not only licit from the point of view of religious law, but even mandatory for the skilled people. However, many subjects are dealt with in this comparatively short book: An epistemology aimed to show that philosophical truth and religious truth are not in contradiction; a sociology of knowledge pointing out that humans are classified in three classes (philosophers, theologians, common folk); a Qur'anic hermeneutics suggesting how to approach philosophically the Holy Book in agreement with religious requirements and linguistic rules.
