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. Franklin, Every Tool Shapes the Task power
The inventive process was often a nonverbal one Through the ages, the professional users of tools by and large have not needed to, been able to, or wanted to talk to outsiders about their implements. They did not need to because tools themselves are used to make other tools, and thus users could very often fashion a new tool with their old ones. If they did need to communicate the design for a new tool to someone outside their trade, they could do so without having to reveal the tool's intended use...Besides, the inventive process of conceiving a new tool was often a nonverbal one. Finally, craftsmen were unwilling to share information about their specialized tools because to do so would have been to give up their competitive edge and their value to those outside the craft.
