Dust thou art, and to dust shalt thou return

“Dust thou art, and to dust shalt thou return” turns a biblical statement of human mortality into a recurring measure of what must be removed, ruined, or remade. The formula first accompanies Franz Biberkopf’s violent expulsion of Otto Lüders, then returns amid the emptied buildings of Alexanderplatz, linking a private rupture to a wider vision of destruction and historical change.

A Formula of Expulsion

When Otto Lüders visits Franz Biberkopf in the room where he has gone into hiding, he brings a few marks and tries to explain himself. He asks Franz for a note confirming that he came, or suggests that Meck or Lina might visit instead. Franz rises, points toward the door, and tells him to leave. At the washstand he takes up the basin and throws its water across the room toward Lüders’s feet. He then grabs the water jug and splashes water at the doorway, striking Lüders on the throat and mouth as he tries to get out. The formula’s movement from dust to return to earth gives this rejection the character of a rough, improvised rite: water is made to carry away the visitor and what he represents.

Cleansing, Ruin, and the Closed Room

After Lüders has gone, Biberkopf throws jugful after jugful of water around the room. He splashes it through the air, insists inwardly that everything must be clean and gone, and opens the window. Yet the action does not leave him in a posture of renewal. He looks down at the wet floor and worries that water will drip onto the people below and stain everything. He closes the window and lies flat on the bed, the dust formula returning beside the stark thought that he is dead. The sequence turns cleansing into exhaustion: the room has been drenched, but the past has not been resolved, and Biberkopf disappears from it that night.

From the Room to Alexanderplatz

The expression reappears in a public landscape of demolition. At Alexanderplatz, the site of Jürgens’s stationery shop has become a building site, while Hahn’s department store stands emptied, cleared out, and gutted, with only scraps of red remaining on its windows. The scene names the ground before it as a rubbish dump and sets the formula against the remains of buildings once regarded as substantial. Rome, Babylon, and Nineveh join Hannibal and Caesar in a catalogue of what has been smashed; the passage then turns from ruin toward rebuilding, noting that the old cities are being excavated and have served their purpose, so new cities can be built.

Meaning and Recurrence

Across these scenes, the formula shifts from a personal weapon to a broad account of material change. In Biberkopf’s room it accompanies the forceful clearing out of a visitor and the desperate wish to make a contaminated space clean; at Alexanderplatz it places modern demolition within a longer succession of cities that fall and are replaced. The comparison with worn-out trousers, which are discarded for new ones, makes that succession bluntly practical rather than elegiac. The phrase therefore holds together mortality, waste, and renewal without making them the same thing: what is destroyed may give way to something new, but the return to dust remains an image of loss, not a promise that the lost will be restored.
