Nevertheless he felt that he should have liked to talk further with Bianca on the subject; of course only to convince her of the absolute injustice of her suspicions. Still she was a woman, a fellow artist; placed in some respects in the same position in relation to the world to which he belonged, as his Paolina--in some respects similar; but oh, thank God, how different! Yet women understood each other in a way a man could never hope to understand them. What immediately struck Bianca, struck her naturally and instinctively in this matter of a marriage between him and the Venetian artist, was the idea that Paolina, almost as a matter of course, was at least biassed in her acceptance of his love by a consideration of the material advantages she would gain by it. It was the natural thing then, the thing a priori to be expected, that a girl in Paolina's position should be so influenced. Ludovico would fain have questioned and cross-questioned La Bianca, his experienced monitress, a little more on this point. Yes, to be expected a priori. But when one knew Paolina; when one knew her as he knew her, was it not impossible? Could it be that Paolina, being such as he knew her in his inmost heart to be, should even adulterate her love with interested calculations? He knew it was not so; and yet--and yet other men had been as certain as he, and had been deceived. In short the germ of doubt had been planted in his mind. And Bianca well knew what she had been about when she planted it there. Why had she done so? She spoke with perfect sincerity when she had told him that she would do much and suffer much for his happiness. And yet she had knowingly placed this thorn in his heart. Why could she not let him, as Quinto Lalli had expressed it, have his Venetian in peace? She spoke truly, moreover, when she said that, married to the Marchese Lamberto, she fully purposed to make him a good and true wife; truly, when she declared to old Lalli, and also to her own heart, that she really did like and admire him much. And yet there was something in the sight of the love of Ludovico and Paolina that was bitter, odious, intolerable to her. Ludovico hastened to the house in the Via di Santa Eufemia on quitting that in the Via di Porta Sisi, not unhappy, not even uneasy; with no recognized doubt, but with a germ of doubt in his mind.
