In this paper I ask how Timaeus explains change within the trianglebased part of his cosmos. Two common views are that change among physical items is somehow caused or enabled by either the forms or the demiurge. I argue for a competing view, on which the physical items are capable of bringing about change by themselves, prior to the intervention of the demiurge, and prior to their being turned into imitations of the forms. I outline three problems for the view (...) that physical things depend on the forms for their causal powers, and show how the view I propose solves each. I then add further arguments for my view, based on (a) statements by Timaeus that seem to favor my view directly, (b) implications of Timaeus’ positions that favor the view, and (c) Timaeus’ explanatory practice in the second half of his speech.

Although the Phaedo never mentions a Form of Soul explicitly, the dialogue implies this Form’s existence. First, a number of passages in which Socrates describes his views about Forms imply that there are very many Forms; thus, Socrates’ general description of his theory gives no ground for denying that there is a Form of Soul. Second, the final argument for immortality positively requires a Form of Soul.

Written by a group of leading scholars, this unique collection of essays investigates the views of both pagan and Christian philosophers on causation and the creation of the cosmos. Structured in two parts, the volume first looks at divine agency and how late antique thinkers, including the Stoics, Plotinus, Porphyry, Simplicius, Philoponus and Gregory of Nyssa, tackled questions such as: is the cosmos eternal? Did it come from nothing or from something pre-existing? How was it caused to come into existence? (...) Is it material or immaterial? The second part looks at questions concerning human agency and responsibility, including the problem of evil and the nature of will, considering thinkers such as Plotinus, Porphyry, Proclus and Augustine. Highlighting some of the most important and interesting aspects of these philosophical debates, the volume will be of great interest to upper-level students and scholars of philosophy, classics, theology and ancient history.

Near the end of his speech, Timaeus outlines a theory of bodily health and disease which has seemed to many commentators loosely unified or even inconsistent . But this section is better unified than it has appeared, and gives us at least one important insight into the workings of physical causality in the Timaeus. I argue first that the apparent disorder in Timaeus’s theory of disease is likely a deliberate effect planned by the author. Second, the taxonomy of disease in (...) the passage consists of one genus subsuming two species. Third, in Timaeus’s theory, health lies between perfect stability and a chaos of all possible motions; this indicates a conception of health as the activation of the body's powers in the right way. A power is a property directed towards bringing about some change. Fourth, the activation of these powers can change depending on the location of their possessors. This last point shows that causation among the physical items in the Timaeus involves structures as well as pushes. (shrink)
