No need to be an inventor or a scientist or a neuroscientist to enjoy inventor Alexander Graham Bell's words of wisdom on any of these gifts. Quote says: "I am a believer in unconscious cerebration. The brain is working all the time, though we do not know it. At night it follows up what we think in the daytime. When I have worked a long time on one thing, I make it a point to bring all the facts regarding it together before I retire; I have often been surprised at the results... we are thinking all the time; it is impossible not to think." Intelligent quote gifts for all those who think -- even when they do not think that they are thinking!
