本文將從班雅明早期對經驗、感覺和認知等方面的論述開始，探討所謂的純粹語言與認知在本質上的相關聯性。首先藉由對〈彩虹：關於奇想的對話〉、〈關於感覺〉以及〈關於未來哲學的規劃〉等文的討論，說明班雅明如何反思傳統知識建構的形式。這其中主要是在於對康德哲學的批評。所批評的重點為：以康德哲學為主的知識系統過於服從科學理性的形式，而這樣的知識結構因太依賴脆弱的主體自我意識，無法形成純粹自主的知識，反而變成知識神話。在此，班雅明提出另一種知識建構的形式之可能。他借助宗教的道理，主張以「更高層次的經驗」為基礎來建立「真實內涵」的知識。在此思考背景下，班雅明在〈關於語言本身與人的語言〉一文裡討論純粹語言的直接傳達，以及如何透過翻譯把人的語言移動轉變至此。這篇文章透露出班雅明對「更高層次的經驗」之探索和發掘，以及表達建立「真實內涵」的知識系統之企圖。

This paper opens by discussing Walter Benjamin’s early views of experience, perception and epistemology to serve as the theoreticalphilosophical foundation for probing the close relationship between the pure language and epistemology in his thought. By interpreting his early works such as The Rainbow: Dialogue on Phantasy, On Perception, and On the Program of the Coming Philosophy, this paper explicates how Benjamin critically reflects on some traditional forms of constructing knowledge. Benjamin’s criticism focuses mainly on Kant’s philosophy. Some of his critical points are: The epistemological system based on Kant’s philosophy conforms to the form of scientific reason. Such an epistemological structure depends too much on the subject’s self-consciousness, which is to some extent unstable; hence, the knowledge based on that is a sort of epistemological mythology. Therefore, Benjamin seeks to revise Kant’s philosophy by integrating the religious doctrine into his reflection about the philosophical tradition. This serves as the foundation of his suggested epistemological system of the “true content.” With this philosophical consideration, Benjamin discusses the pure language, its communicatability, and why translation is meant to remove human language to the pure language in his essay “On Language as Such and on the Language of Man.” In this essay, Benjamin argues the “higher concept of experience” is to be found in the pure language from which the epistemological system of the “truth content” can be developed.
