We have a
hunger of the
mind which asks
for knowledge
of all around
us, and the
more we gain,
the more is
our desire; the
more we see,
the more we
are capable
of seeing.
~ Maria Mitchell

Any piece of
knowledge I acquire today has a value at
this moment exactly
proportioned to
my skill to deal
with it. Tomorrow,
when I know
more, I recall
that piece of
knowledge and
use it better.
~ Mark van Doren
