The review of the development of a psychological unity for the nation provides insight into the issues to be faced when the nation is superseded in favor of a world-state. There are clear advantages that will arise from the formation of a world-state, not the least of which are peace, as well as the more efficient use of resources and addressing the issues of climate change and pollution on a global scale. At the same time, there are risks, or disadvantages which may disturb the process and work against the formation of the psychological unity required for both stability and duration.
Sri Aurobindo notes: “The World-State will give its inhabitants the great advantages of peace, economic well-being, general security, combination for intellectual, cultural, social activity and progress.”
“Peace and security we all desire at present, because we have them not in sufficiency; but we must remember that man has also within him the need of combat, adventure, struggle, almost requires these for his growth and healthy living; that instinct would be largely suppressed by a universal peace and a flat security and it might rise up successfully against suppression. Economic well-being by itself cannot permanently satisfy and the price paid for it might be so heavy as to diminish its appeal and value. The human instinct for liberty, individual and national, might well be a constant menace to the World-State, unless it so skilfully arranged its system as to give them sufficient free play. A common intellectual and cultural activity and progress may do much, but need not by themselves be sufficient to bring into being the fully powerful psychological factor that would be required. And the collective ego created would have to rely on the instinct of unity alone; for it would be in conflict with the separative instinct which gives the national ego half its vitality.”
