把这一句，留给此刻的你

His impact would have been of transient memory and comparatively small importance, had not that impact occurred at a time and in a way to make it supply particulars from which momentous generalizations can properly be projected.

如果这种影响不是发生在某一时期，并以某种方式使其提供了可以恰当地作出重大概括的具体情况，那么他的影响就会是短暂的记忆，而且相对不那么重要。
