What is Physics about

Aristotle's 'Physics' is a foundational text in the study of natural sciences. Written by Aristotle in the 4th century BCE, it systematically explores the principles of motion, causality, and the nature of the physical world. This modern translation, the first since 1930, by David Bostock and Robin Waterfield, makes Aristotle's profound and complex ideas more accessible to contemporary readers. The book includes a lucid introduction and extensive notes that clarify the structure of each section and address particular interpretive challenges, providing a comprehensive understanding of Aristotle's views on physics.

Physics 6 Key Takeaways

Principle of Motion

Aristotle explores the nature of motion, asserting that every motion has a mover and that objects move to fulfill their potential. He categorizes motion into four types: locomotion, alteration, natural growth, and decay.

Four Causes

Aristotle introduces the concept of four causes – material, formal, efficient, and final – to explain why things exist or happen. This framework helps in understanding the underlying principles of physical phenomena.

Nature of Change

According to Aristotle, change is the actualization of potentiality. He elaborates on how substances undergo changes while maintaining their essential nature, a concept fundamental to his physics.

Place and Space

Aristotle defines place as the immediate immovable container of a body and distinguishes it from space, which he views as an extension that bodies may occupy.

Time

Aristotle describes time as a measure of change and motion, linked intrinsically to the concept of 'before' and 'after.' He argues that time cannot exist without change.

The Unmoved Mover

Aristotle introduces the concept of the Unmoved Mover, a primary cause of all motion that itself is not moved by anything else, laying the groundwork for later metaphysical and theological explorations.
