This conceptual article aims to stimulate reflection and debate on the contribution of the philosophy of science to coaching, an area which remains under-represented in the literature. Specifically, critical realism, evolved from the original work of Roy Bhaskar, is proposed as a valuable foundation for developing the knowledge base of coaching in a climate of increasing global complexity. The need for fresh perspectives is discussed and the distinctive features of critical realism are summarised. Examples of how critical realism has already been applied within coaching are provided and the potential benefits for coaching of embracing a critical realist perspective are explored.
