Synergetics : An Adventure in Human Development by Norman Arthur Coulter
Synergy is a complex idea with many facets. There are three interdependent definitions that are mutually synergic:
(a) Synergy is the fusion between different aims and resources to create MORE between the interacting parties than they had prior to the interaction.
(b) Synergy is created by the resolution of apparent opposites and social contradictions.
(c) Synergy grows out of a dialectical and dialogical process of balance, justice, and equality, between persons or groups, and between the ideas and resources they represent; such synergy always exists on multiple levels.
