Something About The Duration Of Past Time

Bob Dylan: Going Going Gone

Therefore
a man should
examine for himself
the great piles
of superimposed strata,
and watch the rivulets
bringing down mud,
and the waves
wearing away
the sea-cliffs,
in order to comprehend
something about
the duration
of past time,
the monuments of which
we see all around us.
--Charles Darwin
On the Origin of Species
