One cannot judge a mortal’s life until their death

“One cannot judge a mortal’s life until their death” expresses a central tension in Sartre’s account of the past: while living, a person is bound to what they have done without being reducible to it; in death, that unfinished relation closes, and the past becomes the person’s definitive record. The proverb makes death the threshold at which a life becomes judgeable as a whole.

The Saying and Its Source

Sartre invokes a proverb spoken by Deianeira in Sophocles’ Trachiniae: the life of a mortal cannot be called happy or unhappy until death. Its force lies not in postponing judgment as a matter of incomplete information alone, but in the way death changes the status of the life being judged. Before that limit, what someone has been remains joined to what they may yet do.

The wording also serves as a bridge between the ancient tragic formulation and Sartre’s philosophical account. It condenses the claim that a person’s life cannot be finally settled while they remain alive, because they continue to take up and sustain their past rather than simply possess it as a finished object.

The Living Relation to the Past

Sartre’s surrounding argument treats “was” as a mode of being. A person does not merely have a past: they are their past. A remark about yesterday’s act or former mood can still wound or flatter, provoke protest, or be allowed to pass, because the person remains involved in what happened. The past is not an indifferent possession set apart from the present self.

A living person can insist that they are no longer what they were, and can point to change or progress. But Sartre describes this dissociation as a secondary reaction: even the attempt to disown a particular part of the past confirms a continuing relation to it. The person remains responsible for reassuming that past in the present, and so cannot yet be identified with it in the fixed manner that death makes possible.

Death and Final Judgment

At death, the possibility of further action ends. Sartre describes the dying person as left with no further card to play: the life can no longer be altered by a new choice. In this sense, death reunites a person with themselves, but it also leaves them defenseless before the judgments of others, who may decide what that life means.

A final repentance cannot simply undo what has congealed through a lifetime. It may be an effort to break away from one’s accumulated being, but death itself becomes one more determination within the whole rather than an escape from it. The person’s former freedom is fixed as part of the past; Sartre says that the for-itself is thereby changed forever into an in-itself. The past, in turn, becomes the growing totality of what the person has been.

Meaning of the Proverb

The proverb does not imply that a living person has no past, or that their past can be discarded. Its distinction is between being what one has been while still freely sustaining and reassuming it, and being that past as a completed totality. While life continues, the person can act on and alter the meaning of what came before; after death, that possibility is gone.

Sartre also connects the saying to the formulation that death changes life into destiny. Together, these expressions mark the same reversal: a life that was lived as an open project becomes, at its end, a fixed whole that others can judge. The proverb’s restraint—judgment must wait—therefore follows from the structure of a life that remains unfinished until death.
