Foolish ideas seem logical if they are repeated often enough. Sun Tzu's strategy teaches the use of analogies to support logic. For example, do the arguments about energy policy make sense in terms of food policy? Current food technology does a thousand times more ecological damage than any other human activity including using oil. Farming cuts down trees, plows up the land, depletes limited water resources, spreads dangerous chemicals, and intentionally poisons natural plants and animals. Using ecologically unsound food is destroying the planet.
