Cleary discusses the origin, development, and use of the many senses of priority as a central thesis in Aristotle's metaphysics. Cleary contends that one of the most revealing problems for the ambiguity of Aristotle's relationship to Platonism is that of the ontological status of mathematical objects. In support of his claim, Cleary analyzes a curious passage from Aristotle's Topics, where he appears to accept a schema of priorities that makes mathematical entities more substantial than sensible things. How does Aristotle try to reconcile the ordering of things dictated by sciences like mathematics and dialectic with the ordering of sense experience upon which his own physics and metaphysics are based? To find the answer, Cleary reviews three different outlines of the many senses of priority given by Aristotle himself and found in Categories 12-13, Metaphysics Delta 11, and Metaphysics Theta 8. Cleary suggests there is an implicit hierarchy for Aristotle that leads him to posit the Prime Mover at its apex as complete actuality and, therefore, as the focus for the concept of priority. Having reviewed Aristotle's treatment of the many uses of priority, Cleary demonstrates how the concept is used in some typical arguments by Aristotle for his mature metaphysical positions.

In Necessary Existence and the Doctrine of Being in Avicenna’s Metaphysics of the Healing Daniel De Haan examines the primary notions being, thing, one, and necessary and their roles in the central argument of Avicenna’s metaphysical masterpiece.

Gregoric investigates the Aristolian concept of the common sense, which was introduced to explain complex perceptual operations that can't be explained in terms of the five senses taken individually. Such operations include perceiving that the same object is white and sweet, or knowing that one's senses are inactive.

"Marmodoro's monograph engages with Aristotle's views on a philosophically challenging question regarding perception, which has been central in the history of philosophy and is very much the focus of current debates in a number of philosophical and psychological disciplines: How do we become perceptually aware of objects in the world? Despite the significance of the question, the ways in which ancient philosophers have addressed it have only just begun to be be explored. There is a great wealth of insight on this question to be found in Aristotle, regarding our ability to perceive items in our environment, which he develops through his very demanding metaphysics, and Marmodo explores these insights in depth here. Aristotle's attempts at accounting for our awareness of complex perceptual content were highly original, drawing on and building on the metaphysics he has developed elsewhere in his works, but have not been adequately explored to date"--
