生命向力是全部生命个体、生命能力与生命意识的总和。人的正方向发展的生命力状态,必然与其创造力大小成正比例关系。人类的政治、经济、哲学、学术等各个方面都显示了这一特征。伟大的思想家往往十分敏锐地关注这方面的情况。恩格斯就是如此。他把文艺复兴时代的成就,与创造这些成就的伟大人物在其性格、情欲、思维能力等方面的强悍和气魄紧密地结合 Life force is the sum of all life individual, life ability and life consciousness. The state of human being’s development in the positive direction must be directly proportional to the size of its creativity. This feature is shown in all aspects of human politics, economics, philosophy and scholarship. Great thinkers are often very keenly concerned about this situation. Engels is the case. He combines the achievements of the Renaissance with the power and courage of the great men who created these achievements in their character, passions, and thinking abilities
