Famous quotes containing the words open and/or defence:
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
“Behold now this vast city; a city of refuge, the mansion house of liberty, encompassed and surrounded with his protection; the shop of war hath not there more anvils and hammers waking, to fashion out the plates and instruments of armed justice in defence of beleaguered truth, than there be pens and hands there, sitting by their studious lamps, musing, searching, revolving new notions.”
—John Milton (1608–1674)
