Po: Beyond Yes and No

Po: Beyond Yes and No by De Bono, Edward. paperback edition. ISBN: 9780140137828.

NO is the basic tool of the logic system. YES is the basic tool of the belief system. PO is the basic tool of the creative system. In the past, ideas have always lived longer than people. Once they were established, ideas would be changed only slowly and over several generations. But today technology and science have so speeded up the rate of change in the world that for the first time ever people actually live longer than ideas. This means that for the first time people need to change their ideas within their lifetime in order to keep up with the world.
