Physics (or "Physica", or "Physicae Auscultationes" meaning "lessons") is a key text in the philosophy of
Aristotle. It inaugurates in the current
Andronichean order, the long series of Aristotle's physical, cosmological and biological works, and is preliminary to them. This collection of treatises or lessons deals with theoretical, methodological, philosophical concerns, rather than physical theories or contents of particular investigations. It sets the bases for the scientist to study the world subject to change, and change, or movement, or motion (kinesis) is one of the chief topics of the work. The ancient Greek title of these treatises - - meant "the [writings] on nature" or "
natural philosophy".
