How did Henri Bergson influence Alfred North Whitehead’s early philosophy?

Alfred North Whitehead’s early philosophical development was influenced by Henri Bergson’s antimechanistic philosophy of change.1

Specifically, Whitehead adopted the view that events serve as the fundamental components of nature and that passage—or creative advance—is its most essential feature. These doctrines, which Whitehead explored in works such as The Concept of Nature (1920), foreshadowed his later metaphysics.1

While Whitehead drew from Bergson’s focus on change, he maintained a distinct perspective by incorporating Platonist elements, arguing that the definite character of these events arises from the ingression of timeless entities.1
