Humanity has experimented with a number of different forms of government in the past. None of these appears to be easily translated to the needs of a complex globe-spanning world-state governing body. It is likely therefore that some modified form must evolve under the pressure of circumstances. Sri Aurobindo indicates that it is more important that the essential needs and functions be met than to try, in advance, to envision the exact form such a government would take: There are historical fixed habits of governance and economics, not to mention culture and embedded religions, that create fixed lines that are generally difficult to break away from. There are also pressures arising from the current world situation which militate that some kind of global governance arise to address them. And there remain the unknowable future events and directions, particularly with the fast evolution of human technology, that themselves are part of the process which will shape the result.
Sri Aurobindo observes: “On the whole, then, whichever way we turn, this question of the form of a World-State is beset with doubts and difficulties that are for the moment insoluble. Some arise from the surviving sentiments and interests of the past; some menace from the rapidly developing revolutionary forces of the future. It does not follow that they can never or will never be solved, but the way and the line any such solution would take are beyond calculation and can really be determined only by practical experience and experiment under the pressure of the forces and necessities of the modern world. For the rest, the form of government is not of supreme importance. The real problem is that of the unification of powers and the uniformity which any manageable system of a World-State would render inevitable.”
