徐光启 / Xu Guangqi
Xu Guangqi enters the wiki through EP259 与苗师傅漫谈徐光启：四百年前如何让人变聪明？, where [[MiaoWeiSanlian|苗伟]] and [[GaoYiding|高一丁]] present him as a late-Ming official whose importance lies in learning and application together. The episode does not treat him only as a high official or Christian convert; it emphasizes his willingness to study difficult new knowledge with [[MatteoRicci|利玛窦]] and translate [[EuclidsElementsChinese|《几何原本》]].
The source makes Xu’s intellectual profile double-sided. On one side, he represents [[EuclideanProofTraining|严密证明训练]] and [[LateMingWesternLearning|晚明西学东渐]]: maps, geometry, astronomy, and the desire to understand “why” rather than only calculate. On the other side, he represents [[AgriculturalReliefStatecraft|农政救荒]] through [[NongzhengQuanshu|《农政全书》]], famine concern, crop promotion, and the practical problem of helping people survive.
Xu also anchors the episode’s statecraft branch. His interest in firearms, city defense, and [[ChongzhenLishu|《崇祯历书》]] shows knowledge being pulled into late-Ming military and imperial-legitimacy crises. The source therefore makes Xu a bridge between [[IntellectualLifeAsPractice|智识生活]], public responsibility, and the political vulnerability of new knowledge.
