“All scientific work is incomplete – whether it be observational or experimental. All scientific work is liable to be upset or modified by advancing knowledge. That does not confer upon us a freedom to ignore the knowledge we already have, or to postpone the action that it appears to demand at a given time. ‘Who knows,’ asked Robert Browning, ‘but the world may end tonight?’ True, but on available evidence most of us make ready to commute on the 8:30 the next day.”
