All Things End—All but Death and Time

“All Things End—All but Death and Time” is the aphoristic conclusion Thebes offers Sully when she asks how he has endured the crew’s crisis. It joins the limits of scientific knowledge to a practical counsel for living: the future and the fate of Earth cannot be controlled by thinking about them, but the present can still be met one moment and one task at a time.

Context and Form

Sully presses Thebes to explain how he has stayed composed and why he has not fallen apart. He does not claim to be whole; he says he is in pieces too, but keeps those pieces separate, handling them “one piece at a time.” His answer makes the expression less a detached maxim than a hard-won way of managing distress.

Thebes makes that method concrete through ordinary routines. He brushes his teeth by thinking only about brushing his teeth, changes an air filter by focusing on that task, and starts conversations when loneliness calls for connection. He tells Sully that she is learning to return from thoughts of elsewhere to the present. Since neither of them can help anyone on Earth merely by thinking about them, attention to the immediate moment becomes a form of endurance rather than denial.

Meaning of the Expression

Thebes connects the saying to Sully’s identity as a scientist: “We study the universe in order to know, yet in the end the only thing we truly know is that all things end—all but death and time.” The turn from the ambition to know the universe to the single certainty of endings gives the line its force. Scientific inquiry may expand understanding, but it cannot exempt human beings from finitude or make loss easier to face.

The wording also holds an unsettling distinction. Individual things end, while death and time are presented as enduring realities against which human lives unfold. Thebes does not use this recognition to offer reassurance that suffering will be solved; he acknowledges that being reminded of it is difficult, and that forgetting it is harder. The expression therefore names a limit without pretending to remove its pain.

Role in Thebes’s Counsel

The phrase gathers the two parts of Thebes’s response to Sully: accept that existence is bounded, and live within the moment that is actually available. His advice is neither to master grief nor to turn away from it. He recognizes that Sully finds the situation hard, pats her hand, and describes a practice of attention and companionship that has helped him and can help both of them.

In this exchange, the cosmic scale of the universe does not make daily acts meaningless. Instead, the contrast between studying vastness and brushing one’s teeth sharpens the value of the present: a small task, or a conversation begun because someone feels lonely, is something a person can still do. The expression is the memorable statement of that tension between ultimate limits and immediate human action.
