"Mao's mind was philosophical and poetic. He felt at home with the Chinese classics. He knew Confucius and his follower Mencius, and he knew how the Ming and the Tang and the other dynasties had handled economics. Statistics bored him. He preferred to leave these details to subordinates. Mao's great strength in the Long March and in the Revolution was his belief in the efficacy of mass action. He was convinced that there was no problem that could not be solved if he mobilized the strength of the masses. He did not literally believe in his famous parable of the old man who moved a mountain, but he did believe he knew how to direct the strength of China's huge population. With that energy there was no goal China could not attain — whether moving a mountain or creating a steel industry or wiping out the opium habit."
