The record is not a good one, but it confirms, on the whole, the view we have suggested that a growth of the sense and conception of humanity may be traced from the time when modern science was born in the sixteenth century. The Middle Ages hardly furnish us with any examples of the action of Christendom towards heathen and weaker people until the Crusades, in which, with rare examples of personal chivalry, the earlier attitude was one of contempt and hatred of the unbeliever. In the conquest of the New World, which was to some of its earliest conquerors a new Crusade, there is the same general savagery marked by rare cases of Christian kindness, such as Las Casas showed. But after the Reformation, when the Church itself had been purified and more human tolerance and care and interest in life prevailed, we find the enlightened Jesuit missions to China and Paraguay, St. Francis Xavier's work in India, and the Quaker dealings with Red Indians in the New World. From the middle of the seventeenth century, slavery, which had fallen into abeyance during the Middle Ages as a domestic institution, began to be denounced as a trade. We are on the threshold of the great humanitarian outburst of the eighteenth century. It is impossible to believe that this growth of human feeling in dealing with other men is unconnected with that new gospel of human power which Bacon and Descartes had just proclaimed. Except for the occasional superman, the greater the powers a man possesses and the higher he rates human capacity at its best, the more careful he is to cherish and develop the germs of humanity in the young and weak. This was undoubtedly the case with the 'philosophers' of the eighteenth century; it is equally true of the nineteenth century, an age wonderful alike for its unexampled development of science and for the rise of activities, national and international, for the betterment of the race. Jointly the western nations have in this period put down the slave trade, and in the Brussels Conference of 1890 we see the highest point yet reached by the united humanity of the West expressed by the assembled states in regard to backward people. The point therefore is a notable one, and Englishmen will be glad to remember that it was Lord Salisbury, then Foreign Secretary, who took the first step. The previous Conference at Berlin, in 1884, had secured freedom of trade for the basins of the Congo and the Niger, and in 1889 Lord Salisbury, through the Belgian Government, called the Powers together to consider questions relating to the slave trade in Africa. For Africa, home of the black race, last exploited of the continents, discovered after the white man had discovered science, was pre-eminently the part of the world where the co-operation of leading peoples in civilizing backward races was most needed and most to be expected. The Congo, the Herreros, Morocco, Tripoli, Omdurman, offer a blood-stained record in reply.
