Sollicitudo Rei Socialis: On Social Concern
12 The first fact to note is that the hopes for development, at that time so lively, today appear very far from being realized. In this regard, the Encyclical had no illusions. Its language, grave and at times dramatic, limited itself to stressing the seriousness of the situation and to bringing before the conscience of all the urgent obligation of contributing to its solution. In those years there was a certain widespread optimism about the possibility of overcoming, without excessive efforts, the economic backwardness of the poorer peoples, of providing them with infrastructures and assisting them in the process of industrialization. In that historical context, over and above the efforts of each country, the United Nations Organization promoted consecutively two decades of development. In fact, some measures, bilateral and multilateral, were taken with the aim of helping many nations, some of which had already been independent for some time, and others - the majority - being States just born from the process of decolonization. For her part, the Church felt the duty to deepen her understanding of the problems posed by the new situation, in the hope of supporting these efforts with her religious and human inspiration in order to give them a "soul" and an effective impulse.
