50 If these efforts are to be successful, they cannot be disparate and disorganized; nor should they vie with one another for the sake of power or prestige. The times call for coordinated planning of projects and programs, which are much more effective than occasional efforts promoted by individual goodwill. As We said above, studies must be made, goals must be defined, methods and means must be chosen, and the work of select men must be coordinated; only then will present needs be met and future demands anticipated. Moreover, such planned programs do more than promote economic and social progress. They give force and meaning to the work undertaken, put due order into human life, and thus enhance man's dignity and his capabilities.
