84 THE SHADOW OF THE WORLD’S FUTURE even migration may be promoted with a sinister inten- tion. It may even happen that one nation is anxious to see migration promoted elsewhere, in order to relieve its own fears of consequences. The whole plexus of relations which modern trans- port and economics, and the intricacies of trade and commerce have established, have really welded the peoples of the earth into a kind of pseudo-solidarity. The evidence of this is that disaster to any one people means some measure of disaster to all.

It is one, however, which needs to be faced. Every day this need becomes nore pressing. There is a reason for this. Man’s power to destroy has been enormously enhanced by recent achievements in chemical and physical science. On the other hand, although his power to ameliorate and meet all evils has also advanced, the measure of this advance is relatively insignificant as compared with his powers of spreading ruin and disaster.
