February 12, 1809 must have seemed like an ordinary day to those alive at the time, but we now know it was the day that two giants of humanity were born: Abraham Lincoln and Charles Darwin. Lincoln ended slavery in the United States in the nineteenth century, and Darwin made one of the greatest scientific discoveries of the nineteenth century.
But the same people vilified both of these great men, often for the same reason: biblical literalists found scriptural reasons to promote slavery and denigrate the theory of evolution.
Lincoln is now revered for what he accomplished — the humanist principle that it is morally wrong for one person to own another is commonly accepted. But moral issues are more easily understood than scientific ones, which is why so many Americans today who reject slavery still cling to a creationist worldview.
