Abstract
With the help of planes and solids, this paper presents an enlargement of the field of observation of economic theory. Through this transformation, the distribution of ownership rights to money and wealth assumes a central position in economic analysis. Thus social relevance is returned to economics. The validity of this operation is confirmed by the return of the millenarian field of economic justice to its traditional function as guidance to economic policy. The paper then presents four sets of economic rights and responsibilities that offer the potential of translating principles of economic justice into the complexities of the modern world.
