无知往往比有知更能让人产生自信:正是那些知之甚少的人,而非那些学识渊博的人,才会如此肯定地断言这个或那个问题永远无法通过科学来解决。
——查尔斯·达尔文《人类的由来》,第一卷,导论
ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
Charles Darwin, The Decsent of Man, Volume I, “Introduction”.
