There is a concept in quantum physics, called “quantum entanglement” which describes the difficult of a pure wave carrying out its force in its native purity and strength due to the “entanglement” of enormous numbers of competing or conflicting waves which confuse the signal. In terms of technology, this translates, more or less, to what is called a “signal to noise” ratio, where the pure wave is the “signal” and all the conflicting waves that interfere with it, distract, or throw it off course, are the “noise”. We can see this principle at work if we consider that an ideal solution that we can envision, such as the free interchange and mutuality of an ideal of human unity which preserves individual freedom and national uniqueness, has little chance of coming to fruition in its pure form at this time due to the large number of conflicting demands and forces at work in the world, such as nationalism, religious strife, greed, corporatism, prejudice, unequal access to education, and manipulation through media and the educational systems that tends to mislead people and fails to create an educated populace that can make rational, positive choices. This means that for at least the present, any advance towards human unity has to take place in a practical sense through the interplay of political, military and economic forces for the most part.
Sri Aurobindo observes: “Ideal conditions cannot be expected, for they demand a psychological clarity, a diffused reasonableness and scientific intelligence and, above all, a moral elevation and rectitude to which neither the mass of mankind nor its leaders and rulers have yet made any approach. In their absence, not reason and justice and mutual kindliness, but the trend of forces and their practical and legal adjustment must determine the working out of this as of other problems. And just as the problem of the State and the individual has been troubled and obscured not only by the conflict between individual egoism and the corporate egoism of the society, but by the continual clash between intermediate powers, class strife, quarrels of Church and State, kings and nobles, king and commons, aristocracy and demos, capitalist bourgeoisie and labour proletariate, this problem too of nation and international unity is certain to be troubled by the claims of just such intermediate powers. To say nothing of commercial interests and combinations, cultural or racial sympathies, movements of Pan-Islamism, Pan-Slavism, Pan-Germanism, Pan-Anglo-Saxonism, with a possible Pan-Americanism and Pan-Mongolianism looming up in the future, to say nothing of yet other unborn monsters, there will always be the great intermediate factor of Imperialism, that huge armed and dominant Titan, that must by its very nature demand its own satisfaction at the cost of every suppressed or inconvenient national unit and assert its own needs as prior to the needs of the new-born international comity.”
