"So, if we've found feet of clay on yet another hero, we've also made the hero larger. For, like Lincoln, Darwin's genius was his ability to let his mind take him where he had not meant to go. Darwin inherited the full set of 19th-century prejudices. Then he created a new scientific vision that laid waste to those very beliefs." -- John H. Lienhard, "Darwin and Racism" (Engines of Our Ingenuity, no. 617)
