Whitehead's philosophy is based on the idea that reality is composed of a multitude of "other realities." He also argues that creativity is not a thing, but a process. Whitehead's Process Philosophy is attractive to people in the Christian tradition because it parallels the idea of a creator God.
Whitehead's philosophy is based on the idea that everything is a process, and that each event is the result of a series of preceding events. In the video, Whitehead discusses how a deep frost can kill spring tulips, and how the decision to freeze them was the culmination of a process that had been going on for weeks. In every event, there is a "nature of the process," which is determined by the objective data that is involved.
