“The human mind always makes progress, but it is a progress in spirals.”
Probably a paraphrase of this line from De l’Allemagne, Pt. 3. ch. 10. "Goethe has made a remark upon the perfectability of the human mind, which is full of sagacity: It is always advancing, but in a spiral line." Not known from Goethe's works.
