Pick two or more works to set their attribute fingerprints, dimension-by-dimension passages, and shared school embodiments side by side. Especially useful for author-stage comparisons (Wittgenstein early vs late) and for setting a single tradition's foundational texts against each other.
Letter on Humanism
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

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
Letter on Humanism
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.
Space
Letter on Humanism
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.
Matter
Letter on Humanism
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.
Observer
Letter on Humanism
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.
Energy
Letter on Humanism
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.
Information
Letter on Humanism
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.
Internal Tensions
Where each work's argument pulls against itself.
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.
