32 In this same Encyclical of Ours We have shown that the means of saving the world of today from the lamentable ruin into which a moral liberalism has plunged us, are neither the class-struggle nor terror, nor yet the autocratic abuse of State power, but rather the infusion of social justice and the sentiment of Christian love into the social-economic order. We have indicated how a sound prosperity is to be restored according to the true principles of a sane corporative system which respects the proper hierarchic structure of society; and how all the occupational groups should be fused into a harmonious unity inspired by the principle of the common good. And the genuine and chief function of public and civil authority consists precisely in the efficacious furthering of this harmony and coordination of all social forces.
