Daily Inspiration Quote by Carl Jung

"Knowledge rests not upon truth alone, but upon error also"

About this Quote

Jung is smuggling a rebuke into what sounds like a calm epistemological slogan. “Knowledge” doesn’t sit on a pedestal of verified facts; it squats on a compost heap of wrong turns, projections, misreadings, and half-true stories we tell ourselves before reality corrects us. The provocation is in the word “rests”: error isn’t a temporary embarrassment on the way to truth, it’s structural support. Pull it out and the whole enterprise collapses into sterile certainty.

The intent tracks with Jung’s broader project: psyche over proof, meaning over mere measurement. In analytic psychology, “error” includes the distortions we’d rather deny - the dream that lies, the memory that edits, the superstition that persists. Those aren’t just bugs; they’re data. A patient’s mistaken belief can be the most honest signal of an underlying conflict. The unconscious, after all, doesn’t speak in clean propositions. It speaks in symbols, substitutions, and defenses - a language that looks like error if you’re expecting a lab report.

The subtext is also a swipe at the modern fantasy of pure objectivity. Jung had watched Freud’s movement harden into doctrine and saw how quickly “truth” becomes a badge of belonging. Error, by contrast, keeps knowledge humble and alive; it forces revision, admits complexity, and resists moralizing. Read historically, in a Europe rocked by world wars and mass ideologies, the line lands as an anti-certainty ethic: the refusal to pretend we’re ever finished learning, or finished being wrong.

Evidence:
Knowledge rests not upon truth alone, but upon error also. (null). This line is attributed (with a specific work title) to Jung’s essay "Freud and Jung: Contrasts" (dated 1929) and is later reprinted in Jung’s Collected Works, Volume 4 ("Freud and Psychoanalysis"). I was not able to access a scan/page image from a publisher-controlled primary text in this browsing session (one major host returned a 403 Forbidden), so I can’t yet verify the exact page/paragraph number from an authoritative edition. However, multiple secondary-but-specific attributions converge on this exact sentence being in that essay; some quote sites instead cite the 1933 English collection "Modern Man in Search of a Soul" (which includes the essay), but those are later republications rather than the first appearance.
