ABSTRACT
THE simple greatness which lies in unconditional surrender to one task is what strikes us when we look back today on this scholarly life. Its inherent logic, inevitability, and power impress us as a natural event. Exclusive meditation on the problems of pure economics formed its content. Nothing else. Nothing disturbs the unity of the whole picture. No other element is of importance in it; it alone affects us. Slowly but steadily, as if by its weight, the achievement of this life’s work impresses itself upon us.
