The agony that America is undergoing is not to be associated with breakdown as much as with the parturition of self-knowledge.

美国疋在经历的痛苦与其是伴离析而来，还不如是伴自我识的而产生的。

As Owen has remarked, the benefit derived from the yielding of the separate pieces in the act of parturition by mammals, will by no means explain the same construction in the skulls of birds and reptiles.

正如欧所， 哺乳动物在娩过程中产生单独的碎片所带来的好处，绝不能解释鸟类和爬行动物头骨中的相同结构。
