Process philosophy originally referred to a small group of philosophers including Henri Bergson, William James, and Alfred North Whitehead as well as Heraclitus. These thinkers view the world processually, working from within things and reversing the relationship between ideas and life. This Handbook explores process philosophy’s relationships to organisation studies by focusing on five aspects: temporality, wholeness, openness and the open self, force, and potentiality. Each article considers the life and work of a specific philosopher, such as Jacques Derrida, Charles Sanders Peirce, George Herbert Mead, Mikhail Bakhtin, Hannah Arendt, and Jacquese Lacan, and how their work could potentially be used to think processually in organization and management studies.
