3 . Libraries made education possible, and education in its turn added to libraries: the growth of knowledge followed a kind of compound interest law, which was greatly enhanced by the invention of printing.藏書使教育成為可能，而教育反過來又豐富了藏書，因為知識的增長遵循著一種「滾雪球」的規律。印刷術的發明又大大提高了知識增長的速度。
4 . With the invention of writing, a great advance was made, for knowledge could then be not only communicated but also stored.隨著書寫的發明，又邁進了一大步，因為這樣一來，知識不僅能交流，而且能儲存了。

Could any spectacle, for instance, be more grimly whimsical than that of gunners ourselves very seriously what will happen if this twofold use of knowledge, with its ever-increasing power, continues.炮兵利用科學毀壞人的身體、而外科醫生就在附近用科學搶救被炮兵毀壞的人體，還有什麼情景比這更可怕、更怪誕的嗎？我們不得不嚴肅地問問我們自己：隨著日益增長的知識的力量，如果我們繼續利用知識的這種雙重性，將會發生什麼樣的情況呢？
14 . The trickle became a stream; the stream has now become a torrent.涓涓細流匯成小溪，小溪現已變成了奔騰的江河。
