The mind's natural preferences motivate the first strategies activated in a problem solving context. The mind also prefers symmetric relations to asymmetric ones. This bias is especially strong among psychologists who study variation in human behavior and mood. By contrast, children who will become inhibited in the second year show a high reactive profile characterized by vigorous motor activity and frequent crying to only some of the episodes. The assumptions that nature consists of asymmetries and of surprises are only two of the premises that Bill Bevan brings to his scholarship. He also appreciates that every event occurs in a context. In a review of a biography of Niels Bohr, F. Wilczek commented on Bohr's appreciation of the inevitability and importance of unexpected observations. Bill Bevan shares many qualities with Alfred North Whitehead. Whitehead believed that the entities that are participants in a functional relation formed a unitary whole.
