Aristotle's "Physics" argues that the natural world is fundamentally characterized by change, which is explained through the principles of motion, causality, and the nature of being. He posits that understanding "nature" requires examining these intrinsic drivers of transformation in all physical entities. The book identifies four causes—material, formal, efficient, and final—as essential for a complete explanation of why things are the way they are and why they change.
Readers will learn to analyze natural phenomena by identifying the potentiality and actuality within objects, the role of prime movers in initiating and sustaining motion, and the concept of place as the innermost limit of a containing body. Aristotle's work establishes a teleological view of nature, where every natural object has an inherent purpose or end towards which it strives.
