Although Pseudo-Dionysius was, after Aristotle, the author whom Thomas Aquinas quoted most frequently, surprisingly little attention has been paid to the role of this Neoplatonist thinker in the formation of Aquinas' philosophy. Fran O'Rourke's book is the only available work that investigates the pervasive influence of Pseudo-Dionysius on Aquinas, while at the same time examining the latter's profound originality. Central themes discussed by O'Rourke include knowledge of the absolute, existence as the first and most universal perfection, the diffusion of creation, the hierarchy of creatures, and their return to God as final end. O'Rourke devotes special attention to the Neoplatonist element in Aquinas' notion of "being" as intensity or degree of perfection. He also considers the relation of being and goodness in light of Aquinas' nuanced reversal of Dionysius' theory of the primacy of the good, and Aquinas' arguments for the transcendental nature of goodness.

Logics of Worlds stands as one of the most important texts in contemporary thought. Conceived as the sequel to Alan Badiou's Being and Event, the book expands upon and elucidates the questions that were posed in the first book. As a complex theory of worlds, the text has, for the most part, been misunderstood, but in William Watkin's diligent and critical close reading of the book, he makes the case for Logics of Worlds being the essential Badiou book for anyone interested in existence, meaning and the potential for radical change. For Watkin, this recasting of ontology is followed by a transformation of logic, which is not only a theory of being, but of appearing and allows Badiou to give new meaning to the object, body and relation. To do this, he explores these concepts through architecture, astronomy and renowned thinkers such as Kant, Hegel and Kierkegaard. For students of French Continental philosophy, ontology and Badiou himself, Watkin's commentary on the philosopher's text provides a brilliant and incisive new interpretation of this underrated work by the leading Continental philosopher of our time.

This study examines the motivations and doctrinal coherence of the Commentary on the Elements of Theology of Proclus written by Berthold of Moosburg, O.P. ( c. 1361/1363). It provides an overview of Berthold's biography and intellectual contexts, his manuscript remains, and a partial edition of his annotations on Macrobius and Proclus. Through a close analysis of the three prefaces to the Commentary, giving special attention to Berthold's sources, it traces the Dominican's elaboration of Platonism as a soteriological science. The content of this science is then presented in a systematic reconstruction of Berthold's cosmology and anthropology. The volume includes an English translation of the three fundamental prefaces of the Commentary.

Horst Ruthrof revisits Husserl's phenomenology of language and highlights his late writings as essential to understanding the full range of his ideas. Focusing on the idea of language as imaginable as well as the role of a speech community in constituting it, Ruthrof provides a powerful re-assessment of his methodological phenomenology. From the Logical Investigations to untranslated portions of his Nachlass, Ruthrof charts all the developments and amendments in his theorizations. Ruthrof argues that it is the intersubjective character to linguistic meaning that is so emblematic of Husserl's position. Bringing his study up to the present day, Ruthrof discusses mental time travel, the evolution of language, and protosyntax in the context of Husserl's late writings, progressing a comprehensive new phenomenological ontology of language with wide-ranging implications for philosophy, linguistics, and cultural studies.

The philosopher Abu Nasr al-Farabi (c. 870-c. 950 CE) is a key Arabic intermediary figure. He knew Aristotle, and in particular Aristotle's logic, through Greek Neoplatonist interpretations translated into Arabic via Syriac and possibly Persian. For example, he revised a general description of Aristotle's logic by the 6th century Paul the Persian, and further influenced famous later philosophers and theologians writing in Arabic in the 11th to 12th centuries: Avicenna, Al-Ghazali, Avempace and Averroes. Averroes' reports on Farabi were subsequently transmitted to the West in Latin translation. This book is an abridgement of Aristotle's Prior Analytics, rather than a commentary on successive passages. In it Farabi discusses Aristotle's invention, the syllogism, and aims to codify the deductively valid arguments in all disciplines. He describes Aristotle's categorical syllogisms in detail; these are syllogisms with premises such as 'Every A is a B' and 'No A is a B'. He adds a discussion of how categorical syllogisms can codify arguments by induction from known examples or by analogy, and also some kinds of theological argument from perceived facts to conclusions lying beyond perception. He also describes post-Aristotelian hypothetical syllogisms, which draw conclusions from premises such as 'If P then Q' and 'Either P or Q'. His treatment of categorical syllogisms is one of the first to recognise logically productive pairs of premises by using 'conditions of productivity', a device that had appeared in the Greek Philoponus in 6th century Alexandria.

This is the first volume exclusively devoted to the Expositio by Berthold of Moosburg (c.1295-c.1361) on Proclus' Elements of Theology. The breadth of its vision surpasses every other known commentary on the Elements of Theology, for it seeks to present a coherent account of the Platonic tradition as such (unified through the concord of Proclus and Dionysius) and at the same time to consolidate and transform a legacy of metaphysics developed in the German-speaking lands by Peripatetic authors (like Albert the Great, Ulrich of Strassburg, and Dietrich of Freiberg). This volume aims to provide a basis for further research and discussion of this unduly overlooked commentary, whose historical-philosophical importance as an attempt to refound Western metaphysics is beginning to be recognized.
