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
207. Good Materials Problem There is a fundamental conflict in the nature of materials for building in industrial society. Solution Use only biodegradable, low-energy-consuming materials, which are easy to cut and modify on site. For bulk materials we suggest ultra-lightweight 40–60 lbs. concrete and earth-based materials like tamped earth, brick, and tile. For secondary materials, use wood planks, gypsum, plywood, cloth, chickenwire, paper, cardboard, particle board, corrugated iron, lime plasters, bamboo, rope, and tile.
