bsolute justice, but as much justice as the
collective intelligence and will of the community are able to put into
force. For the attainment of such a result, the forms of social life
must be constantly altered to keep pace with economic change.

5. _The foregoing principles must apply, not to one man, or class, or
people, but to all men, all classes and all peoples._

Recent events have shown that an injury to one is an injury to all.
Reasoning, foresight and experience will convince the people of the
world that a benefit to one is a benefit to all. While men continue to
live together, their livelihood problems must be thought about
collectively, and the solutions that are determined upon must be applied
to all, without discrimination.

How shall such results be obtained? By what means is it possible to lead
men to a world vision? Who can persuade them to work toward the building
of a sounder society than that with which the world is now laboring?

Of all the issues that confront the teachers of men, this is one of the
most pressing and most insistent. Those who have taken upon themselves
the task of seeking out and of expounding ideas have seldom faced a
graver responsibility than that with which they are at the moment
confronted. World facts demand world thoughts and world acts, before the
human race can adopt saner, wiser and more enlightened economic
policies. World thoughts and acts are impossible without world
understanding. Therefore it is world understanding that is most
imperatively needed in this critical hour.

The people of the world have many things in common--economic interests,
science, art, ideas, ideals. Ranged against these common interests there
are the traditions, prejudices, hatreds, national barriers, sectarian
differences, language obstacles and racial conflicts that have proved so
effective in keeping the peoples separated. The common interests are the
vital means of social advancement, and it is upon them that the emphasis
of constructive thinking must be laid in an effort to promote world
understanding.

There is no need to apologize, then, for adding to groaning library
shelves a book dealing with world economics, the purpose of which is to
propose a plan that will pull together the scattered threads of world
economic life. The time is so ripe for an examination of these problems
that no man may consider himself informed who has not pondered them
deeply, and no man may consider th
