George Spring Merriam, The Negro and the Nation
“ Its existence in one section of the Union is a reproach to us among the nations of the earth, and a blot on the flag. Yet we so thoroughly recognize that our national principle allows each State to shape its own institutions that we have not attempted and shall not attempt to hinder you from cherishing slavery among yourselves as long as you please. If, for the vast and vital interests bound up with the unity of this nation, we can tolerate the presence within it of a system we so disapprove, cannot you on your part tolerate the inevitable criticism which it calls out among us? ”
