Love Quote by Søren Kierkegaard

"Purity of heart is to will one thing"

About this Quote

Kierkegaard’s line doesn’t flatter the reader with innocence; it dares you to pick a center of gravity and live as if it matters. “Purity of heart” sounds like moral hygiene, the scrubbed-soul ideal peddled by piety. Kierkegaard flips it into a question of direction: purity isn’t about having no stains, it’s about refusing to be split. The verb “to will” does the heavy lifting. This isn’t a warm feeling or a correct opinion; it’s commitment enacted over time, the kind that shows up in choices, habits, and what you quietly excuse.

The subtext is a diagnosis of modern distraction before “modern distraction” had a name. Kierkegaard is writing in a 19th-century Denmark where Christianity is socially ambient, a respectable backdrop rather than a lived risk. In that world, you can “will” God and also will comfort, admiration, careerism, and moral self-congratulation. You can want the good and also want to be seen wanting the good. Kierkegaard calls that inner double-bookkeeping the real impurity: not vice, but dividedness.

The phrase “one thing” is intentionally severe. It strips away the alibis of complexity and the romance of being torn. Kierkegaard’s target is the cultivated ambivalence that lets you postpone decision indefinitely. He’s insisting that integrity is singular: not a personality trait, but a chosen aim that organizes everything else. If that feels claustrophobic, it’s meant to. The line is a pressure test for sincerity.

Evidence:
Purity of heart is to will one thing (First part (An Occasional Discourse): 'On the Occasion of a Confession' , often issued in English as 'Purity of Heart Is to Will One Thing'). This line is not originally a spoken remark or interview quote; it is the (English) title/tagline used for Kierkegaard’s 1847 discourse in Danish (commonly cited as 'Hjertets Reenhed er at ville Eet' / modern spelling 'Hjertets renhed er at ville ét'). The discourse first appeared as the first part of Kierkegaard’s 1847 book usually known in English as 'Upbuilding/Edifying Discourses in Various Spirits' (Danish publication dated 1847; commonly given as March 13, 1847). Later, an English translation of this first part was published as a standalone volume: 'Purity of Heart Is to Will One Thing: Spiritual Preparation for the Feast of Confession' (Harper, New York, 1938), translated by Douglas V. Steere. A readily citable secondary confirmation that the work was published in 1847 and that Steere’s translation appeared in 1938 is on the Wikipedia page for the book.
