"Mao's beginnings were commonplace, his education episodic, his talents unexceptional: yet he possessed a relentless energy and a ruthless self-confidence that led him to become one of the world's most powerful rulers. He was one of the toughest and strangest in China's long tradition of formidable rulers who wielded extraordinary powers neither wisely nor well, and yet were able to silence effective criticism for years or even decades by the force of their own character and the strength of their acolytes and guards. Mao need not have done what he did, and it was he alone who ensured that his visions of social and economic change became hopelessly enmeshed with violence and fear. It was his rhetoric and his inflexible will that led to the mobilization of hundreds of millions of Chinese citizens, who - even when they wished to - could find no way to halt the cataract of energy swirling around them."
