By no means sufficient…

Imagine eight brilliant critical thinkers sitting around a table to consider means to improve the town's water supply. None of those brilliant minds can get started until someone puts forward a proposal. […] But where does the proposal come from? Who has been trained to put forward the proposal?

Critical thinking is a very important part of thinking, but it is by no means sufficient. What I so strongly object to is the notion that it is enough to train critical minds.
Edward de Bono, Six Thinking Hats, Chapter 25.
