In the study of history, nothing is more
fascinating than the mergence of those ideas that
periodically galvanize mankind into urgent
action. Such ideas lap onto the center stage of
public awareness, stay for a time and then
effectively vanish. The most interesting
moments in this process, of course, are those
when the idea is on stage, when it engages the
public in passionate debate, when people struggle
to fit the idea into the existing order, and
when, through their effort, people inevitably
change both the existing order and the character
of the idea. -William D. Ruckelshaus , 1985

sticking to a status quo policy until there is
some often-belated recognition that action is
required at this point very large changes are
common. - F.J. Baumgartner, In R. Repetto (2006)
