 I know well that in removing everything upsetting to me (which I believe to be represented only by the imagination) from the idea of an affair, I would judge it healthily and would find in it the remedies as well as the affection which I bring to it. But I have never known how to put this into practice until the passion has already played its role. (Shapiro [ed.] 2007: 93; AT IV, 233–234)
