The Great Undiscovered Ocean Of Truth

I do not know
what I may appear
to the world,
but to myself
I seem to have been
only like a boy
playing on the seashore,
and diverting myself
now and then
finding a smoother pebble
or a prettier shell
than ordinary,
while the great ocean
of truth lay all
undiscovered before me.
--Isaac Newton
(1642-1727)
