Imagination is the eye of the soul.

Joseph Joubert (1754–1824) was a French moralist and essayist best known for his posthumously published notebooks—brief reflections rather than formal treatises. He moved in literary circles that included Chateaubriand, who later edited and issued selections from Joubert’s papers. The remark “Imagination is the eye of the soul” fits Joubert’s characteristic mode: aphoristic, inward, and concerned with the faculties of mind and spirit. It reflects late-Enlightenment and early Romantic-era interest in imagination as a bridge between sensory experience, moral feeling, and religious or metaphysical insight, themes that recur throughout Joubert’s pensées.

The aphorism treats imagination not as mere fantasy but as a faculty of perception. Just as the physical eye lets the body see the visible world, imagination lets the inner self “see” meanings, possibilities, ideals, and spiritual realities that are not directly available to the senses. Joubert suggests that moral and religious understanding depends on this inward vision: imagination animates sympathy, enlarges experience beyond the immediate, and gives form to what the soul intuits but cannot empirically verify. The line also implies a discipline: if imagination is the soul’s eye, it can clarify or distort—so the quality of one’s inner life depends on how that faculty is cultivated.
