„[The integrative system] deals with such matters as respect, legitimacy, community, friendship, affection, love, and of course their opposites, across a broad scale of human relationships and interactions.“
— Kenneth E. Boulding British-American economist 1910 - 1993
Spicer (1997) explains: "Boulding (1989) referred to three independent systems from which power is exercised in our society: threat, production and exchange, and integrative. The threat system is one in which power is accomplished through coercion in its many guises, often including asymmetrical one-way persuasive communication exchanges. The production and exchange system speaks to the economic system, of which public relations is certainly a part. And, finally, the integrative system.

„Thus they are destitute of that very lovely and exquisitely natural friendship, which is an object of desire in itself and for itself, nor can they learn from themselves how valuable and powerful such a friendship is. For each man loves himself, not that he may get from himself some reward for his own affection, but because each one is of himself dear to himself. And unless this same feeling be transferred to friendship, a true friend will never be found; for a true friend is one who is, as it were, a second self.“
— Marcus Tullius Cicero Roman philosopher and statesman -106 - -43 a.C.

Original: (la) Ita pulcherrima illa et maxime naturali carent amicitia per se et propter se expetita nec ipsi sibi exemplo sunt, haec vis amicitiae et qualis et quanta sit. Ipse enim se quisque diligit, non ut aliquam a se ipse mercedem exigat caritatis suae, sed quod per se sibi quisque carus est. Quod nisi idem in amicitiam transferetur, verus amicus numquam reperietur; est enim is qui est tamquam alter idem.
