Two notable doctrines of the courts point ways for ethics. The first is that of property affected with public interest. Applied thus far by the courts to warehouses, transportation, and similar public services, what limits can we set ethically to the doctrine that power of one man over his fellows, whether through his office, or through his property, is affected with public interest? The police power, which sets the welfare of all above private property when these conflict, is a second doctrine whose ethical import far outruns its legal applications. Yet it is by neither of these that the most significant progress has been made toward removing that handicap of inequality which is the chief injustice of our economic system. It is by our great educational system, liberal in its provisions, generously supported by all classes, unselfishly served, opening to all doors of opportunity which once were closed to the many, the most successful department of our democratic institutions in helping and gaining confidence of all--a system of which this University of California is one of the most notable leaders and the most useful members--that fair conditions for competition and intelligent coöperation in the economic world are increasingly possible. V What bearing has this sketch of the significance and progress of coöperation upon the international questions which now overshadow all else? Certainly the world cannot remain as before: great powers struggling for empire; lesser powers struggling for their separate existence; great areas of backward peoples viewed as subjects for exploitation; we ourselves aloof. It must then choose between a future world order based on dominance, which means world empire; a world order based on nationalism joined with the non-social type of competition, which means, every nation the judge of its own interests, continuance of jealousies and from time to time the recurrence of war; and a world order based on nationalism plus international coöperation, "to establish justice, to provide for common defense, to promote the general welfare, and to secure the blessings of liberty to ourselves and our posterity." It is not necessary to discuss in this country the principle of dominance and world empire. It contradicts our whole philosophy. Safety for dominance lies only in a civilization of discipline from above down, in ruthless repression of all thinking on the part of the subject class or race.
