"I lose patience with the argument that because of someone's time, that his limitations are therefore excusable, or even praiseworthy. It is not true that it was impossible in that time and place to look any higher. Think of Wendell Phillips, who, commenting on Abraham Lincoln's proposal to colonize black people out of the country, was sarcastic. He said, ‘colonize the blacks? A man might as well colonize his own hands, or when the robber is in his house, he might as well colonize his revolver.’"
