“Imagination
is more important
than Knowledge.”
“I am not an advocate for
frequent changes in laws
and constitutions. But
laws and constitutions
must go hand in hand
with the progress of the
human mind...with the
change of
circumstances,
institutions must
advance also to keep
pace with the times.”

—Thomas Jefferson
