David Hume argued that cannot be derived from . That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume's words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.
大卫·休谟认为,“应该”不能从“是”中推导出来。也就是说,任何一组事实,再多的科学知识,本身都不足以促使我们采取行动。然而,一代又一代善意的科学家(随着世俗影响在西方日益增强,这样的科学家越来越多)似乎已经忘记了休谟这句睿智的话。所有有动机的行动最终都依赖于无法用科学方法证明的信念,也就是信仰。
