persuade the person that she or he originated it

High quality power is not simply clout. Not merely the ability to get one's way, to make others do what you want, though they might prefer otherwise. High quality implies much more. It implies efficiency - using up the fewest power resources to achieve a goal. Knowledge can often be used ti make the other party like your agenda for action. It can even persuade the person that she or he originated it.
..It can transform enemy into ally. Best of all it can circumvent nasty situations in the dirst place, so as to avoid wasting force or wealth altogether. (Alvin Toffler "Powershift", Chapter 2, High quality power)
