Alfred North Whitehead was a renowned 20th-century British philosopher and mathematician known for his process philosophy and for co-authoring the "Principia Mathematica" with Bertrand Russell.
Whitehead's process philosophy views reality as a dynamic and ever-changing process, rather than a static entity. In his work, "Process and Reality," he introduces the idea of "actual entities" or "actual occasions" that are constantly coming into being, influencing, and perishing. He rejects the notion of static substances and instead focuses on events and processes as the fundamental constituents of reality.
