A Reminder from Darwin

“Ignorance more frequently begets confidence than does knowledge” 

Charles Darwin, The Descent of  Man (vol. I).

See Darwin Online

"This work contains hardly any original facts in regard to man; but as the conclusions at which I arrived, after drawing up a rough draft, appeared to me interesting, I thought that they might interest others. 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".
