Abstract

Plato offers the first metaphysical exploration of the nature of causation and explanation, and the relationship between these and other metaphysical concepts, such as forms, properties, and the soul. Hankinson focuses on two dialogues, the _Phaedo_ and the _Timaeus_; in the first of these, Plato rejects the materialism of natural science, in favour of the good as the ground of teleological explanations, and he invokes forms as invariable causal properties. Plato explores the notion of an _archê_, or ultimate principle, in his argument for the immortality of the soul; this notion comes together with the concept of hypothetical investigation and the casual account of knowledge in the _Timaeus_. Here, Plato offers a cosmogony invoking a divine artificer who fashions the universe from a receptacle, a material substratum that can receive all forms. In Plato's philosophy, there is the emergence of a concern with the correct form that an explanation ought to take, and also an emphasis on teleological explanation.
