Giles of Rome’s On Ecclesiastical Power, a polemical work arguing for the political supremacy of the pope, claims that the papacy holds a ‘plenitude of power’ and has direct or indirect authority over all aspects of human life. This paper shows how Giles uses themes from natural philosophy in developing his argument. He compares cosmic and human ordering and draws an analogy between the relations of soul to body and of Church to state. He also understands the pope’s power to be ‘universal’ in nature, another idea taken from Aristotelian physics. Further, Giles views the pope’s right to intervene arbitrarily in the affairs of the Christian community as mirroring God’s ability to work miracles. We thus see that Giles, no less than intellectuals on the other side of this debate such as Dante and Marsilius of Padua, believed that Aristotelian natural philosophy could be enlisted in the service of political thought.

This book introduces readers to Abū Bakr al-Rāzī (known as Rhazes in Latin), one of the most innovative and divisive figures of the early philosophical tradition in the Islamic world. It attempts to reconstruct his notorious theory of "five eternals" which posited four principles alongside God for the creation of the world, which led Razi to be charged with heresy by other authors. Other topics discussed in depth include his medical works, his alchemical theories, his works on ethics, and his controversial views on religion and prophecy.

L'analisi dell'aristotelismo «platonizzante» nell'ambito della filosofia araba prima della sistemazione della Shifa di Avicenna, secondo cui Dio non avrebbe conoscenza dei particolari, consente all'A. di dimostrare come ci siano stati anche approcci platonici ad Aristotele , che non sono passati attraverso il filtro dei neoplatonici greci. L'altra cosa significativa è il fatto che all'interno della scuola di Baghdad vi sono modi diversi di intendere lo stato ontologico degli universali. L'A. tenta anche di ridimensionare la figura di al-Farabi all'interno della scuola di Baghdad. I filosofi considerati sono al-Farabi, Yahya b. Adi e Ibn al-Tayyib

Peter Adamson offers an accessible, humorous tour through a period of eight hundred years when some of the most influential of all schools of thought were formed: from the third century BC to the sixth century AD. He introduces us to Cynics and Skeptics, Epicureans and Stoics, emperors and slaves, and traces the development of Christian and Jewish philosophy and of ancient science. Chapters are devoted to such major figures as Epicurus, Lucretius, Cicero, Seneca, Plotinus, and Augustine. But in keeping with the motto of the series, the story is told 'without any gaps, ' providing an in-depth look at less familiar topics that remains suitable for the general reader. For instance, there are chapters on the fascinating but relatively obscure Cyrenaic philosophical school, on pagan philosophical figures like Porphyry and Iamblichus, and extensive coverage of the Greek and Latin Christian Fathers who are at best peripheral in most surveys of ancient philosophy. A major theme of the book is in fact the competition between pagan and Christian philosophy in this period, and the Jewish tradition also appears in the shape of Philo of Alexandria. Ancient science is also considered, with chapters on ancient medicine and the interaction between philosophy and astronomy. Considerable attention is paid also to the wider historical context, for instance by looking at the ascetic movement in Christianity and how it drew on ideas from Hellenic philosophy. From the counter-cultural witticisms of Diogenes the Cynic to the subtle skepticism of Sextus Empiricus, from the irreverent atheism of the Epicureans to the ambitious metaphysical speculation of Neoplatonism, from the ethical teachings of Marcus Aurelius to the political philosophy of Augustine, the book gathers together all aspects of later ancient thought in an accessible and entertaining way.
