One must always do what one could

“One must always do what one could” is the recurring principle behind Karl Oskar’s response to uncertainty: he cannot command what happens, but he believes he must act with the means available. Its meaning sharpens aboard the Charlotta, where his effort to save Kristina from a potentially fatal hemorrhage becomes inseparable from his regret that he persuaded his family to emigrate.

Meaning and Earlier Context

The expression is grounded in a contrast between different understandings of human agency and divine will. Nils Jakob’s Son accepts his disability as part of God’s preordination and does not question the Creator. Kristina, too, reads the major turns of her life—including the childhood fall that eventually brought her to Karl Oskar—as events God had directed. Against these convictions, the expression does not claim that people control outcomes; it insists that uncertainty is no reason to abandon action.

That practical outlook appears in the household’s earlier hardships. After Karl Oskar throws hay upward during the harvest, the couple later watches the hay barn burn in a lightning fire. On the way home, Kristina recalls the gesture and tells him that what he asked for happened. The exchange connects his action to a belief that human effort and providence may meet, without establishing that effort can determine what follows.

A Principle in Crisis

During the storm aboard the Charlotta, Danjel reads the passengers the Gospel account of Christ calming a tempest. He understands the storm as a trial of faith and brings the story to those suffering below deck, but the seasick passengers remain absorbed in their own distress. The scene places religious interpretation beside immediate human need: a promise or explanation does not itself relieve those who are suffering.

The expression becomes most urgent when Kristina is bleeding and Karl Oskar fears she may die before the night is over. He remembers that there were people at home who could stop such bleeding, but knows of no one aboard. Rather than accept that nothing can be done, he decides to seek help from the captain, who keeps the medicine chest and acts as the ship’s doctor. Kristina thinks her death may be preordained; Karl Oskar’s opposing conviction is that nothing is so settled that trying to change it is pointless.

The attempt costs him a hazardous passage across the deck in rough weather. When he returns, he learns that the bleeding had stopped, and recognizes that the captain had been the one person aboard able to help. The outcome gives the principle its clearest practical form: effort matters not because it guarantees success, but because without trying Karl Oskar would not have found the available aid.

Responsibility and Limits

The crisis does not end with relief. Believing Kristina may be recovering, Karl Oskar must also face the thought he has tried to evade: he persuaded his wife and children to undertake the voyage, and the family’s suffering makes him feel the weight of that decision. His assertion that someone had to take responsibility now returns as an account he must answer for. The phrase thus bears two related meanings: the duty to act in an emergency and the burden of owning the choices that brought others into danger.

The expression’s force lies in the tension it preserves. Karl Oskar’s persistence does not erase Kristina’s belief in divine purpose, nor does a favorable turn make the voyage safe or his decision consequence-free. It instead names a limited but consequential human freedom: one cannot know the outcome in advance, but one can still try, and one must still accept responsibility for having chosen.
