And as I received a few others containing greetings tardy or retarded by the overburdening of the mails at that season, on the third and fourth of January I hoped still, but my hope grew hourly more faint. Upon the days that followed I gazed through a mist of tears. This undoubtedly meant that, having been less sincere than I thought in my renunciation of Gilberte, I had kept the hope of a letter from her for the New Year. And seeing that hope exhausted before I had had time to shelter myself behind another, I suffered as would an invalid who had emptied his phial of morphia without having another within his reach. But perhaps also in my case--and these two explanations are not mutually exclusive, for a single feeling is often made up of contrary elements--the hope that I entertained of ultimately receiving a letter had brought to my mind's eye once again the image of Gilberte, had reawakened the emotions which the expectation of finding myself in her presence, the sight of her, her way of treating me had aroused in me before. The immediate possibility of a reconciliation had suppressed in me that faculty the immense importance of which we are apt to overlook: the faculty of resignation. Neurasthenics find it impossible to believe the friends who assure them that they will gradually recover their peace of mind if they will stay in bed and receive no letters, read no newspapers. They imagine that such a course will only exasperate their twitching nerves. And similarly lovers, who look upon it from their enclosure in a contrary state of mind, who have not begun yet to make trial of it, are unable to believe in the healing power of renunciation. In consequence of the violence of my palpitations, my doses of caffeine were reduced; the palpitations ceased. Whereupon I asked myself whether it was not to some extent the drug that had been responsible for the anguish that I had felt when I came near to quarrelling with Gilberte, an anguish which I had attributed, on every recurrence of it, to the distressing prospect of never seeing my friend again or of running the risk of seeing her only when she was a prey to the same ill-humour. But if this medicine had been at the root of the sufferings which my imagination must in that case have interpreted wrongly (not that there would be anything extraordinary in that, seeing that, among lovers, the most acute mental suffering assumes often the physical identity of the woman with whom they are living), it had been, in that sense, like the philtre which, long after they have drunk of it, continues to bind Tristan to Isolde. For the physical improvement which the reduction of my caffeine effected almost at once did not arrest the evolution of that grief which my absorption of the toxin had perhaps--if it had not created it--at any rate contrived to render more acute.
