Abū’l-Barakāt is a renowned philosopher of the Arabic-Jewish milieu who composed in his magnum opus the Kitāb al-Mu‘tabar, a comprehensive metaphysics which challenged the accepted notions of the traditional metaphysical philosophy. ‘Abū’l-Barakāt al-Baghdādī’s Metaphysical Philosophy’ examines the novel philosophical conceptions of the first book of the Metaphysics of the Kitāb al-Mu‘tabar. The aim is to present a developed conception of Abū’l-Barakāt’s systematic metaphysics. This is accomplished by following the order of topics discussed, while translating the relevant passages. These different topics comprise stages of cognition that move from an analysis of time, creation and causality to the conception of a higher spiritual realm of mental entities and a conception of God as the First Knower and Teacher. The epistemological and ontological conceptions are analyzed at each culminating stage. ‘Abū’l-Barakāt al-Baghdādī’s Metaphysical Philosophy’ analyzes vast portions of the metaphysical study for the first time. The book will thus be a valuable resource for all those seeking an original and broad metaphysics, and for students and scholars of Jewish and Islamic Philosophy. Furthermore, it is of importance for those seeking a metaphysics related to scientific theories and those interested in the history of science and metaphysics.

Abū’l-Barakāt is often considered one of the most comprehensive philosophers of the Arabic-Jewish milieu in the medieval age. His extensive and unique philosophical theories, especially his theories in the particular sciences, were seen as a major challenge for the traditional conceptions of the Aristotelian school of thought during and after this period. ‘Abū’l-Barakāt al-Baghdādī’s Scientific Philosophy’ explores the core material of Abū’l-Barakāt’s scientific studies, found in his magnum opus the Kitāb al-Mu‘tabar. The book then locates these scientific theories within Abū’l-Barakāt’s philosophy more widely. Whilst providing a comprehensive critique of ancient philosophy, including the work of Aristotle, certain affinities between Abū’l-Barakāt’s work and that of more modern scientific conceptions are also examined. Containing vast amounts of previously untranslated text, ‘Abū’l-Barakāt al-Baghdādī’s Scientific Philosophy’ sheds new light on the philosopher’s scientific theories, particularly with regards to his logical conceptions. For this reason, the book will be a valuable resource for students and scholars of Jewish and Islamic Philosophy, whilst the scientific material will appeal to those studying the history of science.

The so-called "Theology of Aristotle" is a translation of the Enneads of Plotinus, the most important representative of late ancient Platonism. It was produced in the 9th century CE within the circle of al-Kindī, one of the most important groups for the early reception of Greek thought in Arabic. In part because the "Theology" was erroneously transmitted under Aristotle's authorship, it became the single most important conduit by which Neoplatonism reached the Islamic world. It is referred to by such thinkers as al-Fārābī, in an attempt to demonstrate the agreement between Platonism and Aristotelianism, Avicenna, who wrote a set of comments on the text, and later on thinkers of Safavid Persia including Mullā Ṣadrā. Yet the "Theology" is not just a translation. It may in fact more accurately be described as a creative paraphrase, which takes frequent liberties with the source text and even includes whole paragraphs' worth of new material. Adamson's book offers a philosophical interpretation of the changes introduced in the Arabic version. It is argued that these changes were in part intended to show the relevance of Plotinus' thought for contemporary Islamic culture, for instance by connecting the Neoplatonist theory of the First Principle to theological disputes within Islam over the status of God's attributes. At the same time the paraphrase reflects a tendency to harmonize the various strands of Greek thought, so that a critique by Plotinus of Aristotle's theory of the soul is subtly changed into a defense of Aristotle's theory against a possible misinterpretation. The upshot, or so Adamson argues, is that the "Theology" needs to be read as an original philosophical work in its own right, and understood within the context of the ʿAbbāsid era.
