內容摘要：本文主要就海德格早期弗萊堡時期的一些文獻，討論他從原初的生命處境去談語言、科學，乃至文化之如何生成。具體言之，對於「生命自行解釋出意義」，對於從「在己生命」到「在己與為己的生命」，或對於「生命的趨勢與自我滿足性」的要求，是讓生命處境生成原初語言的根本動機。這進一步生成出的「表述關連」與「展現關連」就包括文化、文明及各種科學的形成。而本文將生命處境與原初語言連接到原初理性，則是鑒於海德格晚期對於logos的更深入體認，將logos不只視為一般所了解的理性、語言，甚或聚集、統合，展現理據，而更視為讓流動的、具開顯與遮蔽交替的生命展現出來；logos本身也以顫動的、既具揭蔽性又具遮蔽性的語言呈現。海德格既將理性reason一詞回溯至這種logos，故就顯示它具備原初理性的意涵。這是本文從海德晚期回頭看早期生命處境與原初語言時，欲從其思想的問題性，而暫不計其歷史性的立場出發所做的一種觀察與連結。

Abstract: This article discusses Heidegger’s deliberation of the generation of language, science and culture from the original life situation, mainly according to his early literatures in Freiburg period. Precisely speaking, the demands of “the self-explication of the meaning of life,” “the development from life in itself to life in and for itself,” and “the tendency of life and its self-filling,” are the basic motive of the generation of the original language from the life situation. This further develops “the relation of expressions” and “the relation of manifestations” in terms of culture, civilization and any sort of science. Furthermore, this article connects the life situation and the original language with the original reason, with regard to Heidegger’s deep comprehension of logos in his later period. He understands logos not merely as reason, language, or even as collection, unification, and expression of justification (logon dinonai), but rather as letting the life be manifested in its floating and changeable form of disclosing and closing. Logos self also manifests language in the form of vibration, and with the both uncovering and covering functions. Since Heidegger traces the term “reason” back to logos in this sense, logos shows the meaning of “the original reason.” This is an observation and connection from the standpoint of Heidegger’s whole problematic, instead of his historical development of thinking, as we review his early conceptions of the life situation and the original language from his later thinking.
