In this paper, I explore the origins of the ‘problem of universals’. I argue that the problem has come to be badly formulated and that consideration of it has been impeded by falsely supposing that Platonic Forms were ever intended as an alternative to Aristotelian universals. In fact, the role that Forms are supposed by Plato to fulfill is independent of the function of a universal. I briefly consider the gradual mutation of the problem in the Academy, in Alexander of (...) Aphrodisias, and among some of the major Neoplatonic commentators on Aristotle, including Porphyry and Boethius. (shrink)

A fairly long (~15,000 word) overview of ancient theories of freedom and determinism. It covers the supposed threat of causal determinism to "free will," i.e., the sort of control we need to have in order to be rightly held responsible for our actions. But it also discusses fatalistic arguments that proceed from the Principle of Bivalence, what responsibility we have for our own characters, and god and fate. Philosophers discussed include Aristotle, Epicurus, the Stoics, Carneades, Alexander of Aphrodisias, and Plotinus. (...) Plato is mentioned in passing a few times in connection with other philosophers. (shrink)

The article examines the state of research on Michael of Ephesus as a probable author of the Commentaries on Metaphysics E–N, mainly the works of Leonardo Tarán and Concetta Luna. In spite of their opposed views, they both agree on the mediocrity of the Byzantine author. The article questions the criteria for this negative appraisal and offers some material for reconsidering Michael of Ephesus’ idea of philo­sophical culture.

In "De anima" 3.5, Aristotle argues for the existence of a second intellect, the so-called "Agent Intellect." The logical structure of his argument turns on a distinction between different types of soul, rather than different faculties within a given soul; and the attributes he assigns to the second species make it clear that his concern here -- as at the climax of his other great works, such as the "Metaphysics," the "Nicomachean" and the "Eudemian Ethics" -- is the difference between (...) the human and the divine. If this is right, we needn't go on a wild goose chase trying to invent a role for the so-called Agent Intellect to play. God moves our intellects as he moves the heavenly spheres, "as a beloved": he constitutes the complete actualization towards which all of our intellectual striving is directed. Aristotle regards such final causation as an efficient cause, but not in a way that would make it part of what we would call the causal processes or mechanisms of human psychology. But, he would insist, it is essential for appreciating who we are and what our place is in the world. (shrink)

This piece of work intends to shed light on Alexander of Aphrodisias from the second-century Aristotle commentator through the history of Aristotelian psychology up to the sixteenth century's clandestine prompter of the new philosophy of nature. In the millennium after his death the head of the Peripatetic school in Athens served as the authority on Aristotle in the Neo-Platonic school, survived the Arabic centuries of philosophy as Averroes' exemplary exponent of the mortality of the soul and as such was not (...) considered worthy of translation by the Latin Scholastics. This attitude changed only in the Late Middle Ages, when the resistance against Averroes grew fierce and Alexander emerged as the only Aristotelian alternative to him. In 1495 his account of Aristotle's psychology was translated and published and the underlying principles of a natural philosophy, based on sense perception and exempt from metaphysics, became accessible. The prompt reception and widespread endorsement of Alexander's teaching testify to his impact throughout the sixteenth century. (shrink)

According to Alexander of Aphrodisias, our potential intellect is a purely receptive capacity. Alexander also claims that, in order for us to actualise our intellectual potentiality, the intellect needs to abstract what is intelligible from enmattered perceptible objects. Now a problem emerges: How is it possible for a purely receptive capacity to perform such an abstraction? It will be argued that even though Alexander's reaction to this question causes some tension in his theory, the philosophical motivation for it is a (...) sound one. Rather than a calculation of actualities and potentialities, the doctrine of receptivity is supposed to explain how human beings come to grasp universal aspects of reality in an accurate manner.
