 As Darwin’s theory of evolution introduced history into the conceptualization of biology, Samuel Alexander (1859–1938), Henri Bergson (1859–1941), and C. Lloyd Morgan (1852–1936) introduced development into the ways in which all of physical reality was conceptualized. They then worked out positions that in a variety of ways understood God and the world as growing in relationship to each other. Although Hartshorne’s classification of “panentheism” did not include Alexander in the category of “panentheism,” only occasionally mentioned Bergson, and made no reference to Morgan, Whitehead referred to all three of these thinkers positively. It may be too strong to claim that they influenced Whitehead (Emmett 1992), but they did provide the background for Whitehead’s and then Hartshorne’s systematic development of process philosophy as an expression of panentheism. Hartshorne popularized the modern use of the term “panentheism” and considered Whitehead to be the outstanding panentheist (Hartshorne 1953, 273). Although Hartshorne made several modifications to Whitehead’s understanding of God, the basic structures of Whitehead’s thought were continued in Hartshorne’s further development of Whitehead’s philosophy (Ford 1973, Cobb 1965). God, for process philosophy, is necessary for any actual world. Without God, the world would be nothing more than an unchanging existence radically different from the actual world of experience. God as both eternal and temporal provides possibilities that call the world to change and develop. God as eternal provides an actual source of those possibilities. However, if God is only eternal, the possibilities would be unrelated to the actual world as it presently exists. Thus, Whitehead and Hartshorne understand the world to be present in God in order for the possibilities that lead to development to be related to the world (Hartshorne 1953, 273). The implication of God’s inclusion of the world is that God is present to the world and the world influences God. Although the presence of the world in God could be understood as a form of pantheism, process philosophy avoids collapsing the world into God or God into the world by maintaining a distinction between God and the world. This distinction is manifest in the eternality of God and the temporality of the world. It is also apparent in the freedom of the events in the world. Although God presents possibilities to the events in the world, each event “decides” how it will actualize those possibilities. The freedom of each event, the absence of divine determination, provides a way for process thought to avoid God being the cause of evil or containing evil as evil. Since God includes the events of the world, God will include the evil as well as the good that occurs in the world and this evil will affect God since the world affects God’s actualization. But, because God does not determine the response of each event to the possibilities that God presents, any event may reject God’s purpose of good through the intensification of experience and actualize a less intense experience. God does take this less intense, evil, experience into God’s self, but redeems that evil by means of relating it to the ways in which good has been actualized. Thus, God saves what can be saved from the world rather than simply including each event in isolation from other events (J. Cooper 2006, 174, 180).
