The simplest logic posits order: the basest survival instinct is insistent appeal for order, for primal form: the whole nervous system's constantly jostled continuities and particularities of thought prompt thought's ultimatum--ordered form (to degree of agnostic, atheistic negation/positivistic BELIEF) in "crystal clear", like we say--giving that "cluster" of, then, centered idea the word "God": gender, generatrix, generator, evermore.
