What is time? What is its nature? Is time something natural or cultural? Is it the property of knowing objects or the property of knowing subjects? How has time been conceived, defined, and characterized throughout history by philosophical and scientific thinking? What are the theoretical obstacles that have historically prevented a better understanding of time? Why does that concept still remain so mysterious and enigmatic these days? In the search for the answers to these and other questions, this article explores the concept of time of one of the greatest and most influential sociologists of the 20th century—the German Norbert Elias (1897–1990)—whose sociological theory has been of great value to the debate on the problems of contemporary society. In recent decades, his reflections on time that guided by a holistic and procedural perspective have caused a spreading impact, becoming compulsory reading for anyone wanting to study the topic. By questioning and critical analysis of the bases on which Elias’ concepts of time are founded, this article aims to instigate and contribute to a debate founded on the nature of time.
