" To overcome this he proposed to "dissect" the "tasks and relevant authority" of government on "functional lines." Only the "[f]unctional integration of materiel activities on an international scale and cultural devolution on a regional basis", he argued, offered the "most hopeful way out of international anarchy."The four lectures he gave at Yale were later published as The Progress of International Government (1933)."

Second, several groups of functional agencies would be coordinated.
Third, the functional agencies would then collaborate with certain international planning agencies. Mitrany envisaged two such agencies: an International Investments Board and an International Development Commission.
