Page 193 - Who finds not Providence all good and wise, Alike in what it gives and what denies ? VII. Far as creation's ample range extends, The scale of sensual, mental powers ascends : Mark how it mounts to man's imperial race, From the green myriads in the peopled grass ! What modes of sight betwixt each wide extreme!
Page 42 - Political liberty consists in the power of doing whatever does not injure another.
