Certainly institutions play a role in maintaining humankind's tragic direction.
However, they could have a role in changing the course.
Consider for a moment that
a) governments play a "following" role rather than a "leading" role
in human existence.
governments came into existence following agricultural surplus
governments function follows from a need to:
constrain uncivilized individual action within the group.
economies of scale,
specialization of labor, and
protected trade, and
reduction in supporting resources
untenable distribution of resources
outside competition for internal resources
acquisition of outside resources
b) After initial formation governments calcify and
change only with large pushes from:
(think suffrage or abolition)
population: (think plague, migration, reproduction)
resources (think soil water, minerals, energy)
Now given this view how do we unwind the human predicament.
Let me suggest three steps.
1) we change the common will without
any initial attempt to change common behavior.
That is we get a large number (maybe half of the earth’s population) to
a) reject the current course and expected future conditions.
b) visualize a working system
(a future sustainable peaceful civilization) and,
c) understand which actions transition our current civilization to
this new one
2) this group forces its institutions to enact laws
to implement these actions (think abolition and suffrage)
3) the new laws coerce the behavior that implements the new civilization.
