We physicians had need be a self-confronting and a self-reproving race; for we must be ready, without fear or favor, to call in question our own Experience and to judge it justly; to confirm it, to repeal it, to reverse it, to set up the new against the old, and again to reinstate the old and give it preponderance over the new.
