In the beginning Communism showed itself for what it was in all its perversity; but very soon it realized that it was thus alienating the people. It has therefore changed its tactics, and strives to entice the multitudes by trickery of various forms, hiding its real designs behind ideas that in themselves are good and attractive. Thus, aware of the universal desire for peace, the leaders of Communism pretend to be the most zealous promoters and propagandists in the movement for world amity. Yet at the same time they stir up a class-warfare which causes rivers of blood to flow, and, realizing that their system offers no internal guarantee of peace, they have recourse to unlimited armaments. Under various names which do not suggest Communism, they establish organizations and periodicals with the sole purpose of carrying their ideas into quarters otherwise inaccessible. They try perfidiously to worm their way even into professedly Catholic and religious organizations. Again, without receding an inch from their subversive principles, they invite Catholics to collaborate with them in the realm of so-called humanitarianism and charity; and at times even make proposals that are in perfect harmony with the Christian spirit and the doctrine of the Church. Elsewhere they carry their hypocrisy so far as to encourage the belief that Communism, in countries where faith and culture are more strongly entrenched, will assume another and much milder form. It will not interfere with the practice of religion. It will respect liberty of conscience. There are some even who refer to certain changes recently introduced into soviet legislation as a proof that Communism is about to abandon its program of war against God. (Papal Encyclical, Divini Redemptoris, 19 March 1937).
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
