The most effectual means of being secure against pain is to retire within ourselves, and to suffice for our own happiness. Those, which depend on ourselves, are the only pleasures a wise man will count on: for nothing is ours which another may deprive us of. Hence the inestimable value of intellectual pleasures. Ever in our power, always leading us to something new, never cloying, we ride, serene and sublime, above the concerns of this mortal world, contemplating truth and nature, matter and motion, the laws which bind up their existence, and that eternal being who made and bound them up by these laws. Let this be our employ. Leave the bustle and tumult of society to those who have not talents to occupy themselves without them. Thomas Jefferson
