"I think my first impression – dominantly one of native shrewdness – was probably correct. And yet Mao was an accomplished scholar of Classical Chinese, an omnivorous reader, a deep student of philosophy and history, a good speaker, a man with an unusual memory and extraordinary powers of concentration, an able writer, careless in his personal habits and appearance but astonishingly meticulous about details of duty, a man of tireless energy, and military and political strategist of considerable genius."
