康有为的《孟子微》以阐发孟子思想的"微言大义"为宏旨，通过对"性善"、"仁"的重新诠释，为中国社会找到了适用于西方进化理论的可能性、动力和标准，将西方社会进化论融入传统思想。康有为立足孟子思想，提出重"时"、重"仁"，强调阶段性发展的"三世"进化思想，并对严复译介、宣传的西方进化论展开理性矫正。康有为《孟子微》一书具有鲜明的时代意蕴，其进化思想演绎着传统和时代的双重变奏，昭示着中西方思想文化由交织到融合的可能性，折射出调融中西方思想的智慧和勇气，对我们当下正确对待中西方思想文化具有启发和借鉴意义。

From the perspective of the "Eastward Spread of Western learning", KANG You-wei's Deep Meaning of Mencius had distinct characteristics of the times in the late Qing Dynasty. In The Deep Meaning of Mencius, KANG integrated Chinese tradition with Western evolutionism. He discovered in Mencius the applicability of evolutionism in China, and put forward his evolutionism of "three eras", emphasizing "time", "benevolence" and periodical development. KANG also tried to rectify evolutionism translated and advocated by YAN Fu. Representing the dual variation between tradition and times, and reflecting the wisdom and courage of integrating Chinese and Western thoughts, KANG's evolutionism in The Deep Meaning of Mencius is significant for us to deal with Chinese and Western cultures.
