Jordan B. Peterson, Maps of Meaning: the Architecture of Belief (1999) 185-186 > As such, a given cultural structure necessarily must meet a number of stringent and severely constrained requirements: (1) it must be self-maintaining (in that it promotes activities that allow it to retain its central form); (2) it must be sufficiently flexible to allow for constant adaptation to constantly shifting environmental circumstances; and (3) it must acquire the allegiance of the individuals who compose it. [...] Furthermore, the group solution must appear ideal – in comparison to any or all actual or imaginable alternatives. The compelling attractiveness of simplistic utopian ideologies, even in the “skeptical” twentieth century, is evidence for the stringent difficulty of this final requirement.
