展延心靈論的提出已有十年之久，以對工具的掌握為其心靈理論的起點，對於展延心靈開展時內在面的控制角色，一直還留有一個理論發展的空間。本文站在展延心靈論內部維護的立場，以展延心靈之控制運作所產生的內容為基礎來進行理論發展：展延心靈的確有一個內在核心，它在展延心靈開展的過程裡占有顯著重要的角色，那就是儘可能地維護支持內容，那是一種新意義的內容，是動態性的內容，由作用者對內在資源的組織方式所構成，用以支持作用者掌握工具運用的種種活動表現。本文並以展延心靈論中曾討論過的幾種人與外在資源契合的方式，來說明作用者如何藉著支持內容來構成心靈的內在核心，這個內在核心比之外在工具的用處仍然有其不可忽視的特殊重要性。

The thesis of the extended mind has been upheld for a decade and defended seriously. However, within the thesis the role of internal mentality (that controls various tools) standing in the unfolding of the extended mind seems to have been underestimated. The present paper provides a new perspective within the thesis of the extended mind: the extended mind indeed has an inner core that has a distinctive role in the extended mind’s course of unfolding, to wit, to maintain a novel sense of content—the supporting content—in order to flexibly support agents’ performance. Such content is conceived of as ways of organizing activities: when the extended mind unfolds, it continues to hold to an inner core that constantly serves to organize internal men-tal resources (including attention and internalized tools) in support of the agent’s problem-solving performance in the environment and/or cultural settings. The supporting content qua content on the system-atic connection between an agent’s controlling states and her per-forming activities. The aforementioned distinctive role of maintaining supporting content, this paper argues, manifests that the extended mind has an inner core that is reasonably privileged in comparison to external resources.
