Sometimes leaders need to stretch the boundaries of realism to inspire their followers and call forth extra effort, as Winston Churchill did in Great Britain in 1940. But, without a degree of prudence based upon comprehension of the context, visions turn from grand to grandiose and undercut the values that they seek to promote.
当然，一味的谨慎渐进也是不够的。有时候领导人就需要突破现实的藩篱去激励追随者并激发出额外的效应，如同温斯顿·丘吉尔1940年在英国所做的那样。但如果没有对背景的理解，没有基于这种理解的某种程度上的谨慎，远景很容易从宏大沦为浮夸，从而损害了它所追求的价值。
