It has often and confidently been asserted, that man's origin can never be known: but 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 Descent of Man - 1871
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. - Et sinn déi, déi wéineg wëssen, an net déi déi vill wëssen, déi sech sou sécher sinn, datt dësen oder dee Problem ni wäert vun der Wëssenschaft geléist ginn." - Introduktioun vun The Descent of Man, 1871.
