把这一句，留给此刻的你
The business of a Political Economist is neither to recommend nor to dissuade, but to state general principles, which it is fatal to neglect, but neither advisable, nor perhaps practicable, to use as the sole, or even the principal, guides in the actual conduct of affairs
政治经济学家的工作既不是建议也不是劝阻，而是陈述一般原则，忽视这些原则是致命的，但把它们作为指导实际事务的唯一甚至主要原则，既不可取，也不可行
