思想的生命力在于与时俱化，以适应时代的需要。汉代之所以推行"罢黜百家，独尊儒术"的方略，正因为先秦儒学在其衍化的过程中，逐步实现了从文化儒学向政治儒学的转向。这一转向，不仅使得先秦儒学成为超越具体时代而相通于人类精神的文化儒学，而且还成为与生活世界息息相关的政治儒学；不仅为儒学的推廓与发展奠定了基础，而且也为中国传统文化在"新时代"进行创造性转换、创新性发展提供了历史借鉴。

Constant advancing with the time constitutes the vitality of thought. In the Han Dynasty, the policy of advocating Confucianism only while rejecting all other doctrines was performed. This was due to the transformation from cultural Confucianism to political Confucianism in pre-Qin. This transformation advanced pre-Qin Confucianism to cultural Confucianism of mankind beyond particular times on the one hand, and also political Confucianism closely related to the life world. This transformation made later development of Confucianism possible. In addition, we can also learn much from this historical transformation for creative transformation and innovative development of Chinese traditional culture in the "new era".
