People acting politically are commonly assumed to be immune to the limitations and ‘imperfections’ that afflict people acting non-politically. The force that somehow infuses near-godlike abilities and motives into people acting politically remains forever mysterious.

It is a dogma that is both more absurd and more dangerous than nearly all of the many others that have so often duped human beings into mindsets of self-destruction.
