Having access to the Lego bucket of raw data, humans are compelled to make operating structures to interface the millions of bits into manageable chunks. Some choose to build houses to dwell in, others are lit with the wish to craft spaceships that will ferry them through the asteroid field of experience, where they might glean valuable minerals and alien organisms for further research. Others build to see how gravity works (philosophers), or purely under an experimental Geist (such as artists).
By this analogy, belief-systems are like meta-structures, or templates that people adopt and subsequently model their buildings upon. Each religion (or school), and each denomination (or discipline), possesses certain characteristics that appeal to distinct types of thinking, feeling, and action. And within each system there are those who wish to follow the template more or less exactly, and who distrust any deviation from those instructions (or interpretations thereof).
As well, those who exist outside such constructs sometimes see them as prisons, even as insulting to their intelligence, which finds fulfillment in the act of exploration and experiment. These persons see truth as always in flux, and frame the game as a contest of invention.
While this playmate is sitting crisscross applesauce in the rainbow pile, the others have taken their accepted models and started playing house or battlebots, until an accident or vigorous playmate breaks their construct, and back to the template they must go.
Returning to the pile for a missing piece, there they find the inventor/ investigator, who has already discovered a few novel combinations in the chaos of potentiality. Sadly, each of these are lying forgotten in a pile behind him, discarded by the hands already onto something else.
