Letter on Humanism
Brief über den Humanismus — Heidegger's 1946 letter to Jean Beaufret, the central late-period statement of the Kehre
Tradition: Continental philosophy / late Heidegger
After the Kehre — language is the house of being, the human is the shepherd of being, and humanism is the metaphysical forgetfulness to be overcome
The Letter on Humanism is the central published statement of Heidegger's late thought after the "turn" (die Kehre) of the 1930s. Written in 1946 in response to questions from Jean Beaufret in Paris (and partly in answer to Sartre's 1946 lecture Existentialism is a Humanism), the Letter develops three positions that mark Heidegger's late-period shift away from Being and Time's framework: that "language is the house of being," that the human is not the master but the "shepherd" of being, and that every humanism — Christian, Marxist, existentialist, liberal — remains within the metaphysical forgetfulness of being that the late Heidegger's thought attempts to overcome. The Letter shaped post-war French philosophy (Levinas, Derrida, Lacan) and the broader twentieth-century "anti-humanist" turn.

School Embodiments
The Letter on Humanism remains a phenomenological work — the analysis of language, the call of being, and the human relation to truth as unconcealment all extend phenomenological method.
"Language is the house of Being. In its home man dwells. Those who think and those who create with words are the guardians of this home." (Letter on Humanism, opening)
The late Heidegger's critique of metaphysics, his rejection of every humanism, and his treatment of language as the medium of thinking shaped Derrida, Foucault, and the broader French postmodern turn more directly than any other twentieth-century work.
"Every humanism is grounded in a metaphysics or is itself the basis of one. Every determination of the essence of man that presupposes an interpretation of being... is metaphysical." (Letter on Humanism)
The Letter is partly a rejection of Sartre's existentialist humanism — Heidegger insists that his "existentialism" of Being and Time has been misread and that the Kehre has moved his thought beyond the subject-centred frame existentialism retains.
"Sartre states the basic tenet of existentialism in this way: 'Existence precedes essence.' But the reversal of a metaphysical statement remains a metaphysical statement." (Letter on Humanism)
The late Heidegger's engagement with Hölderlin, the pre-Socratics, and what he calls the "destinal" sendings of being places him near the broader esoteric tradition of philosophical readings of being. The connection is genuine, though Heidegger himself would resist the label.
"Being is the destiny of thought." (Letter on Humanism, paraphrasing the late-period formula)
A real philosophical kinship: the late Heidegger's treatment of being as event (Ereignis), as the happening of unconcealment, has structural similarities with Whitehead's process metaphysics. Both reject substance-ontology as the framework of philosophy.
"Being itself 'is' the relation insofar as it gathers ek-sistence to itself as the locality of the truth of being." (Letter on Humanism)
Less an embodiment than a critical relation: the Kantbuch (1929) read Kant as fulfilment of phenomenology; the Letter on Humanism reads even Kant as part of the metaphysical tradition the Kehre has moved beyond.
"Metaphysics has, in a way unknown to itself, been refused the simple question of what man is." (Letter on Humanism)
Graham Harman and the OOO tradition read the late Heidegger as the principal twentieth-century philosophical resource for a non-anthropocentric ontology of being. The Letter is one of the most cited late texts.
"Man is the shepherd of being. Man loses nothing in this 'less'; rather, he gains in that he attains the truth of being." (Letter on Humanism)
Heidegger's late critique of technological enframing (Gestell) and his recovery of dwelling as the human relation to earth shaped the deep ecology movement (Naess, Foltz, Bruce Foltz, Michael Zimmerman).
"To save the earth is more than to use it up. Saving the earth does not master the earth and does not subjugate it." (the formula Heidegger develops in "Building Dwelling Thinking" — consonant with the Letter's anti-humanism)
The late-Heidegger's analysis of being as the relation that gathers thinking, language, and the human is one of the most influential relational ontologies in twentieth-century philosophy.
"The relation to being is letting itself rather than acting." (Letter on Humanism — the famous "letting be," Gelassenheit)
Continental-philosophical tradition.
Internal Tensions
The relation between Being and Time (1927) and the late work is the central interpretive question of Heidegger studies. The Letter on Humanism asserts continuity ("there is no Heidegger I and Heidegger II"), but the late language — destinal sending, the call of being, the shepherd metaphor — has a quasi-religious register that the early existential-analytical work lacked. The compare-pair with Being and Time on this site makes the shift legible. The other major tension is Heidegger's Nazi affiliation in the 1930s and the relation between his thought and his politics, intensified by the 2014 publication of the Black Notebooks.
I. Time
The late Heidegger's analysis of time shifts from Being and Time's temporality (Zeitlichkeit) toward a more "destinal" treatment — being "sends" itself in epochs, each granting a different determination of the truth of beings. Time emerges from the event of being itself; the human responds, does not initiate.
Attributes
II. Space
Space is the field of dwelling — relational and lived. The Letter's concern with the human as shepherd rather than master implies a spatial humility: we do not occupy space, we are addressed by it.
Attributes
III. Matter
The late Heidegger turns increasingly to a relational treatment of the earth — matter as the source from which beings emerge into unconcealment. "Building Dwelling Thinking" (1951) is the locus classicus; the Letter's anti-humanism is the philosophical preparation.
Attributes
IV. Observer
The late-Heidegger observer is the "shepherd of being" — embodied, plural, fundamentally passive in the precise sense of being addressed and responding rather than initiating. Knowledge is immediate (thinking is responsive to being's call) and finite. No personal metaphysical agency; being is no personal God. Moral authority is experience — thinking, dwelling, attending — rather than tradition or revelation.
Attributes
V. Energy
The energetic principle is the "event of appropriation" (Ereignis) — being's self-giving in the relation that gathers thinking, language, and world. Emergent from no prior cause; the late Heidegger explicitly rejects the search for first causes as the metaphysical forgetfulness to be overcome.
Attributes
VI. Information
Language is the substantival informational medium of being's self-revelation: "language is the house of being." But language here is relational, not a static repository. Personal information is not conserved across death; the late Heidegger's treatment of mortality continues the Being-and-Time analysis without retracting it.
