for it was not knowledge but unity that she desired, not inscriptions on tablets, nothing that could be written in any language known to men, but intimacy itself, which is knowledge
Unity of command is essential to the economy of time. Warfare in the field was like a siege: by directing all one's force to a single point a breach might be made, and the equilibrium of opposition destroyed.
You use force, you create fear. Fear destroys trust. Trust is the basis of harmony. The hardliner believes harmony and unity can be brought by force. That's totally unscientific, totally wrong.
