Life & Wisdom Quote by Henrik Ibsen

Sin, in Ibsen’s world, isn’t a naughty slip; it’s a kind of commitment. “Really to sin you have to be serious about it” flips the usual moral arithmetic. The most corrosive wrongdoing isn’t the impulsive vice but the deliberate one: the choice you rehearse, justify, and build a life around. He’s poking at the comforting fiction that people become “bad” by accident. No, Ibsen implies, the truly destructive acts come with a clear-eyed will, even a perverse integrity.

The line’s sting is how it smuggles intention into morality. To “sin” here isn’t simply breaking a rule; it’s investing yourself in the breach. That targets a familiar bourgeois evasiveness: the respectable person who wants the thrill or advantage of transgression without the self-image cost. Ibsen was obsessed with that gap between public virtue and private calculation, where denial becomes its own craft. Seriousness is the tell. It’s what turns a momentary lapse into a system.

There’s also a sly jab at moral grandstanding. If sin requires seriousness, then sanctimony can look like a mirror image: another kind of theater performed with solemn conviction. Ibsen’s characters often weaponize earnestness, using duty, religion, or “what people will say” as a moral alibi. The quote reads like a diagnosis: guilt isn’t always proof of conscience; it can be proof of how thoroughly someone has chosen their part.
