把这一句，留给此刻的你
Perhaps, to the uninformed, it may appear unaccountable that a man should be able to retain in his memory such a variety of learning; but the close alliance with each other, of the different branches of science, will explain the difficulty.
也许，对于无知的人来说，一个人能够在记忆中记住如此丰富的知识似乎是不可思议的;但是，不同科学分支之间紧密的联盟将会解释这一困难。
