Ignorance Begets Confidence
"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
"Darwin didn't know 99 percent of what we know, but the 1 percent he did know was the most important part."
Francisco Ayala
University of California biologist
