Motion is not just a new way to think about the world. It is a synthetic description of life in the 21st century based on our shared experience of increasing mobility, displacement, and instability. These movements are changing every structure on the planet we previously thought was stable. We are entering a startling new epoch where every aspect of life in science, society , technology, and nature itself is increasingly deﬁned by movement and mobility. The philosophy of movement is an attempt to understand the new spirit of our times, how we got here , the consequences of these changes, and how we can move better together. The philosophy of movement is motivated by four significant contemporary phenomena that force us to rethink the nature and centrality of movement.
