Though the Commission was concerned with environmental problems arising from rampant exploitation of the earth's resources, it rejected the notion of limits to growth voiced by those who believed that the world's resources were limited. Instead it took the stand that infinite growth was possible if the mental and organizational resources available to humanity in the form of knowledge, technology, vocational skills and modes of organizations were fully utilized. ICPF noted with concern the marked absence of a body of theoretical knowledge concerning the process of development and issued a call for efforts to formulate a comprehensive theory of social evolution.
