Much social conflict emerges out of the individual desire to expand and make replicas of itself.
All conflicts have causes that are infinitely complex. But to take two individuals in conflict, both of whom have a certain nature and a certain way of interacting with reality as a consequence of that nature, we can express this conflict by stating that these separate natures are in tension with one another.
An intractable conflict occurs when both individuals have overriding desires to replicate themselves simultaneously, to solve the conflict in their own way, both solutions of which reproduce the conflict.
