本文將透過馮特在《民族心理學》中的語言手勢起源論，論述語言表達的意義基礎，應在表情與手勢等身體姿態上。馮特的意義身體姿態構成論源自十九世紀的語言哲學傳統，本文因而也將追溯十九世紀歷史比較語言學的語言心理學轉向，以說明史坦塔爾對於洪堡特內在語言形式的心理學闡釋，如何影響馮特嘗試將語言意義的可理解性，建立在基於民族共通感的情感與身體表達運動之上。這些說明同時也將確立，十九世紀的民族心理學，實已開創了文化科學之語言學奠基的思路。

Based on the gestural theory of language origins that Wundt of-fered in his Folkpsychology, this paper aims to justify the notion that the foundation of the meaning of words lies in bodily gestures, such as facial and pantomimic expression. Since Wundt’s body gesture theory of meaning derives from the tradition of philosophy of language in the nineteenth century, this paper would also retrace to the psycho-logical turn within historical comparative linguistics in that century, and explain how Steinthal’s psychological exposition of Humboldt’s inner language form carried weight with Wundt’s insight that the ac-cessibility of the meaning of language should be established upon ex-pressive movements of affection and the body. These explanations will, at last, reveal Wundt’s concept of folkpsychology as a linguistic foundation of cultural science.
