'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.'
所有的科学工作都是不完整的——无论是观察性的还是实验性的。所有的科学工作都有可能随着知识的进步而被推翻或修改。这并不意味着我们可以无视已经掌握的知识,或者推迟在特定时间看来需要采取的行动。
