I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

As Socrates recounts his search for causes (aitiai) in the Phaedo, he identifies the following as genuine causes: intelligence (nous), seeming best, choice of the best, and the forms. I argue that these causes should be understood as norms prescribing the conditions their effects must meet if those effects are to be produced. Thus, my account both explains what Socrates’ causes are and the way in which they cause what they cause.

Towards the close of Book V of theRepublicPlato tells us that the true philosopher has knowledge and that the objects of knowledge are the Forms. By contrast, the ‘lovers of sights and sounds’, he tells us, have no more than belief, the objects of which are physical particulars. He then goes on to present us with some very radical-sounding assertions about the nature of these physical particulars. They are bearers of opposite properties, he says, in so thorough-going a manner that (...) we cannot say of them that they are nor that they are not: they lie somewhere between being and utter non-being.This passage of theRepublic still awaits an agreed interpretation and I want to suggest as a reason for this that it is usually interpreted in isolation. I will argue that it becomes easier to understand when seen against the background of Plato's developing thought. To be more precise, it makes sense when taken as a rejection by Plato of one of his earlier beliefs: namely, a doctrine of essentialism to be found in thePhaedo.The greater part of this paper then will be an attempt to show thatRepublicV is a rejection of thePhaedo'sdoctrine of essences. Its concluding part will try to explain why that doctrine was rejected. (shrink)

In this paper there are two claims that I wish to defend. One is that in Socrates’ much discussed “causal” theory concrete particulars are more central than Forms. The other is that these concrete particulars are held by Plato to be not simply bundles of characteristics, not mere meeting-points of Forms, but independent individuals, existing in their own right.It will not, I believe, be questioned that from one point of view the prime concern of the Phaedo is with concrete particulars; (...) not with Forms, characteristics, or anything else. For, the overriding aim of the dialogue is, surely, to persuade us each to care for his own soul; it is for this reason that arguments are put forward to show that souls are indestructible. But there is no doubt that these souls are particulars. (shrink)

In Plato’s Timaeus, two different theories – the Receptacle theory and the geometrical particle theory – are presented to explain change in the natural world. In this paper, I argue that there is tension between the two theories. After examining several possible solutions for this tension, I conclude that Plato does not present it as something ready to be solved within the dialogue but, rather, as something to be understood in a way that maintains both theories. Finally, I also argue (...) that the contrast between the two theories in the Timaeus derives from a similar contrast in the Phaedo. (shrink)
