She believed then that at bottom she had a different morality. Of course the morality of civilised persons has always much in common; but our young woman had a sense in her of values gone wrong or, as they said at the shops, marked down. She considered, with the presumption of youth, that a morality differing from her own must be inferior to it; and this conviction was an aid to detecting an occasional flash of cruelty,an occasional lapse from candour, in the conversation of a person who had raised delicate kindness to an art and whose pride was too high for the narrow ways of deception. Her conception of human motives might,in certain lights, have been acquired at the court of some kingdom in decadence, and there were several in her list of which our heroine had not even heard.She had not heard of everything, that was very plain;and there were evidently things in the world of which it was not advantageous to hear. She had once or twice had a positive scare; since it so affected her to have to exclaim, of her friend, "Heaven forgive her,she doesn't understand me!" Absurd as it may seem this discovery operated as a shock, left her with a vague dismay in which there was even an element of foreboding. The dismay of course subsided, in the light of some sudden proof of Madame Merle's remarkable intelligence; but it stood for a high-water-mark in the ebb and flow of confidence. Madame Merle had once declared her belief that when a friendship ceases to grow it immediately begins to decline—there being no point of equilibrium between liking more and liking less. A stationary affection, in other words, was impossible—it must move one way or the other.However that might be, the girl had in these days a thousand uses for her sense of the romantic, which was more active than it had ever been. I do not allude to the impulse it received as she gazed at the Pyramids in the course of an excursion from Cairo, or as she stood among the broken columns of the Acropolis and fixed her eyes upon the point designated to her as the Strait of Salamis; deep and memorable as these emotions had remained. She came back by the last of March from Egypt and Greece and made another stay in Rome. A few days after her arrival Gilbert Osmond descended from Florence and remained three weeks, during which the fact of her being with his old friend Madame Merle, in whose house she had gone to lodge, made it virtually inevitable that he should see her every day. When the last of April came she wrote to Mrs. Touchett that she should now rejoice to accept an invitation given long before, and went to pay a visit at Palazzo Crescentini, Madame Merle on this occasion remaining in Rome. She found her aunt alone; her cousin was still at Corfu. Ralph, however,was expected in Florence from day to day, and Isabel,who had not seen him for upwards of a year, was prepared to give him the most affectionate welcome.
