The excessive segmentation of knowledge, the rejection of metaphysics by the human sciences, the difficulties encountered by dialogue between science and theology are damaging not only to the development of knowledge, but also to the development of peoples, because these things make it harder to see the integral good of man in its various dimensions. The “broadening [of] our concept of reason and its application” is indispensable if we are to succeed in adequately weighing all the elements involved in the question of development and in the solution of socio-economic problems.
32. The significant new elements in the picture of the development of peoples today in many cases demand new solutions. These need to be found together, respecting the laws proper to each element and in the light of an integral vision of man, reflecting the different aspects of the human person, contemplated through a lens purified by charity. Remarkable convergences and possible solutions will then come to light, without any fundamental component of human life being obscured.
Economic science tells us that structural insecurity generates anti-productive attitudes wasteful of human resources, inasmuch as workers tend to adapt passively to automatic mechanisms, rather than to release creativity. On this point too, there is a convergence between economic science and moral evaluation. Human costs always include economic costs, and economic dysfunctions always involve human costs.
It should be remembered that the reduction of cultures to the technological dimension, even if it favours short-term profits, in the long term impedes reciprocal enrichment and the dynamics of cooperation. It is important to distinguish between short- and long-term economic or sociological considerations. Lowering the level of protection accorded to the rights of workers, or abandoning mechanisms of wealth redistribution in order to increase the country's international competitiveness, hinder the achievement of lasting development.
Moreover, the human consequences of current tendencies towards a short-term economy — sometimes very short-term — need to be carefully evaluated. This requires further and deeper reflection on the meaning of the economy and its goals, as well as a profound and far-sighted revision of the current model of development, so as to correct its dysfunctions and deviations. This is demanded, in any case, by the earth's state of ecological health; above all it is required by the cultural and moral crisis of man, the symptoms of which have been evident for some time all over the world.
