Twain was an adamant supporter of the abolition of slavery and the emancipation of slaves, even going so far as to say, "Lincoln's Proclamation ... not only set the black slaves free, but set the white man free also".[109] He argued that non-whites did not receive justice in the United States, once saying, "I have seen Chinamen abused and maltreated in all the mean, cowardly ways possible to the invention of a degraded nature ... but I never saw a Chinaman righted in a court of justice for wrongs thus done to him".[110] He paid for at least one black person to attend Yale Law School and for another black person to attend a southern university to become a minister.[111]
