對於儒家哲學而言，關於身體討論，不會僅只生理上的器官與四肢，也同時兼含生活歷史中個體身分的理解，而帶有「我」之擴張的狀態，且會將「體」、「身」與「心」連動做一個完整表述。在此論點的基礎上，反思智慧型手機此科技產品作為現代日常必須，譬如：手機不離身；面對這表面上作為「器」、「物」，但又不僅於「器」、「物」的科技產品，孔孟會以「體」的擴張來理解嗎？抑或是我們將其以「身體思維」來看待更適切。而「身體思維」與智慧型手機又是一個怎樣的身體互動？筆者以論語「君子不器」的觀點進行開展，以孟子「知言養氣」的章節中論及「志」的重要性給予儒家理論中可能提供對身體思維的規範參考，以此對智慧型手機作為體之延伸進行反思。

In Confucian philosophy, the concept of the body extends beyond mere physiological organs and limbs. It encompasses an understanding of individual identity within the context of one’s life and history, integrating the “body” and “mind” into a unified expression. Building on this premise, this paper explores the relationship between technological products and the body, particularly in light of our constant interaction with smartphones. Can such technological products be regarded as mere “tools,” which Confucian thought might interpret as extensions of the “body”? Or would it be more appropriate to examine them through the lens of “bodily thinking”? Moreover, how does this “bodily thinking” interact with the body in the context of mobile phone? The author expands on the Analects’ perspective that “the gentleman is not a mere instrument”(君子不器) and draws on Mencius’ discussion of zhi (志, will) in the chapter Knowing Words and Cultivating Qi (知言養氣). These Confucian theoretical insights offer a potential framework for understanding and regulating bodily thinking. Based on this foundation, the author reflects on mobile phone as an extension of the body.
