From Joseph Campbell, The Hero With A Thousand Faces:
“The universal triumph of the secular state has thrown all religious organizations as a definitely second ary, and finally ineffectual, position that religious pantomime is hardly more today than a sanctimonious exercise for Sunday morning, whereas business ethics and patriotism stand for the remainder of the week. Such monkey-holiness is not what the functioning world requires; rather a transmutation of the whole social order is necessary, so that through every detail and act of secular life the vitalizing image of the universal-god who is actually immanent and effective in all of us may somehow be made known to consciousness.”
Not to be confused with Immanant, a term in mathematics, or imminent, a word meaning “soon to happen”.
Immanence refers to philosophical and metaphysical theories of divine presence, in which the divine is seen to be manifested in or encompassing the material world. It is often contrasted with theories of transcendence, in which the divine is seen to be outside the material world.
So, yeah, clouds would be a pretty handy example of the sort of omnipresent reminder that Campbell speaks of here.
PROOF OF GOD! ...and other tragedies.
