"The psychological effects of the Long March are much more intangible. For Mao, at least, the experience served to reinforce his voluntaristic faith that people with the proper will, spirit, and revolutionary consciousness could conquer all material obstacles and mold historical reality in accordance with their ideas and ideals. For those who survived the ordeal-and for those who were inspired by the story of their survival-the experience, however bitter it was at the time, gave rise to a renewed sense of hope and a deepened sense of mission. People must be able to hope before they can act; they must possess not only ideals and a sense of mission, but hope and confidence that they will be able to realize their ideals through their own actions. More than any other event in the history of Chinese Communism, it was the Long March-and the legendary tales to which it gave rise-that provided this essential feeling of hope, the confidence that determined people could prevail under even the most desperate conditions. And more than any other individual, it was Mao Zedong who radiated and inspired this faith in the future. It was a faith not only in those deemed capable of molding the future in accordance with Communist hopes but also in the values regarded as essential to the eventual realization of those hopes. The familiar Maoist virtues of unending struggle, heroic sacrifice, self-denial, diligence, courage, and unselfishness were values espoused not by Mao alone but carried and conveyed by all of the veterans of the Long March, for these were the values they had come to regard as essential to their own survival and to the survival of the revolution to which they had devoted their lives. These ascetic values lay at the core of what later came to be celebrated as "the Yan'an spirit.""
