"All great qualities are never found in any one man or in any one race. The whole of humanity, like the whole of everything else, is ever greater than a part. Men only know themselves by knowing others, and contact is essential to this knowledge. In one race we perceive the predominance of imagination; in another, like the Chinese, we remark its almost total absence. In one people we have the reasoning faculty; in another the genius for music; in another exists courage, in another great physical vigor, and so on through the whole list of human qualities. All are needed to temper, modify, round and complete the whole man and the whole nation. Not the least among the arguments whose consideration should dispose us to welcome among us the peoples of all countries, nationalities and colors, is the fact that all races and varieties of men are improvable. This is the grand distinguishing attribute of humanity, and separates man from all other animals. If it could be shown that any particular race of men are literally incapable of improvement, we might hesitate to welcome them here. But no such men are any where to be found, and if they were, it is not likely that they would ever trouble us with their presence. The fact that the Chinese and other nations desire to come and do come is a proof of their capacity for improvement and of their fitness to come."
