"Never has the human race enjoyed such an abundance of wealth, resources and economic power, and yet a huge proportion of the worlds citizens are still tormented by hunger and poverty, while countless numbers suffer from total illiteracy. Never before has man had so keen an understanding of freedom, yet at the same time new forms of social and psychological slavery make their appearance. Although the world of today has a very vivid awareness of its unity and of how one man depends on another in needful solidarity, it is most grievously torn into opposing camps by conflicting forces. For political, social, economic, racial and ideological disputes still continue bitterly, and with them the peril of a war which would reduce everything to ashes. True, there is a growing exchange of ideas, but the very words by which key concepts are expressed take on quite different meanings in diverse ideological systems. Finally, man painstakingly searches for a better world, without a corresponding spiritual advancement. Influenced by such a variety of complexities, many of our contemporaries are kept from accurately identifying permanent values and adjusting them properly to fresh discoveries. As a result, buffeted between hope and anxiety and pressing one another with questions about the present course of events, they are burdened down with uneasiness. This same course of events leads men to look for answers; indeed, it forces them to do so."
