Power makes knowledge sufficient Whether it is civil rights' violations in many countries, whether it is the increasing numbers of unemployed people in our own country, whether it is the homeless we see on our way to work, it isn't as though we don't know. But there is that horrible realization that, while the knowledge of facts may be a necessary condition for action, and we talk about democracy in civic action, it is unfortunately not a sufficient one. While knowledge may be a necessary condition, it may in fact be a less necessary condition that the one that makes that a sufficient condition, and that is access to power. Ursula M.
