"The frivolity and boredom which unsettle the established order, the
vague foreboding of something unknown, these are the heralds of
approaching change.  The gradual crumbling that left unaltered the
face of the whole is cut short by a sunburst which, in one flash,
illuminates the features of the new world."  --G.W.F. Hegel,
_Phenomenology of Spirit_ 5:11
