Does being in motion change how we think? Tracing the connections between thinking and transit—including walking, being transported by a vehicle, and many other modes—this innovative book shows how embodiment and movement deepen, expand, and transform creative thought. Megan Craig and Edward S. Casey provide a collaborative phenomenological exploration of thought in motion, interspersing lively first-person accounts with broader philosophical inquiry. Their investigation, structured around the four ancient elements—water, air, earth, and fire—ranges across swimming, boats, balloons, planes, cars, trains, and other modes of transport. Craig and Casey invite readers to recall their own experiences of travel and how thinking changes in tandem with shifting environments and whatever conveys a person from place to place. They also consider how changing climates and evolving technologies, with new rhythms and materialities, have shaped human thinking in its many varieties. Thinking in Transit celebrates forms of movement and motion that carry the body and mind out of their habituated routines. This book urges a change in how philosophers have traditionally framed the setting for serious thought: from the austere, solitary space of a study to populated places of interaction and passage.
