This volume investigates the evolution and significance of the search for definitions as a foundational practice in Ancient Greek philosophy. Edited by Professor David Charles, the text compiles fourteen original essays from prominent scholars to address how thinkers from Socrates to Plotinus conceptualized the act of defining. The work argues that definition has been an under-examined subject in contemporary scholarship and seeks to re-establish its importance within the history of logic and metaphysics.

Scholars recognize this collection as a specialized resource that fills a significant gap in the study of ancient logic and methodology. Readers frequently note the academic density of the prose, which is intended for advanced students and researchers of classical philosophy.
