For James, the big question is, how do we explain the emergence of monotheism?
So, let's give him an answer. How monotheism?
A sense of wonder is the primary impulse of religion.
Early conceptions of deities were attempts to define and categorize the sense of awe inherent within human beings and their social groups.
James describes the singular focus of that awe as an All-Father.
These All-Fathers clearly were not just glorified human souls or departmental spirits, since they were represented as having existed before death entered the world, and still exist in the sky, where they dwell in remote seclusion, usually disinterested in human affairs. Sometimes they are thought to have lived at one time on earth ...
James states that theories of a "primeval revelation" (such as by Schmidt) fail due to lack of evidence.
[T]here is no possible means of ascertaining scientifically the original beliefs of mankind about anything. (James)
The theory of primeval revelation raises more problems than it solves, for James. And it goes well beyond any sociological or anthropological evidence.
[T]he function of a Supreme Creator must be limited by the creative outlook of almost culture less tribes for whom the problems of causation have little or no meaning. (James)
The All-Father belief seems to represent the purposive functioning of an inherent type of thought and emotion rather than an elaboration of a certain kind of knowledge concerning the universe. (James)
It is driven by a desire to identify and name the "awful and mysterious power" at the basis of what we perceive to be as the order of the world.
