Pierre boldly ventured to discuss this point. "But won't you admit, doctor, the possibility of some disorder of the will?" he asked. "Has it not been proved, is it not admitted nowadays, that when certain degenerate creatures with childish minds fall into an hallucination, a fancy of some kind or other, they are often unable to free themselves from it, especially when they remain in the same environment in which the phenomenon occurred? Cloistered, living alone with her fixed idea, Bernadette, naturally enough, obstinately clung to it." The doctor's faint smile returned to his lips, and vaguely waving his arm, he replied: "Ah! my child, you ask me too much. You know very well that I am now only a poor old man, who prides himself but little on his science, and no longer claims to be able to explain anything. However, I do of course know of that famous medical-school example of the young girl who allowed herself to waste away with hunger at home, because she imagined that she was suffering from a serious complaint of the digestive organs, but who nevertheless began to eat when she was taken elsewhere. However, that is but one circumstance, and there are so many contradictory cases." For a moment they became silent, and only the rhythmical sound of their steps was heard along the road. Then the doctor resumed: "Moreover, it is quite true that Bernadette shunned the world, and was only happy in her solitary corner. She was never known to have a single intimate female friend, any particular human love for anybody. She was kind and gentle towards all, but it was only for children that she showed any lively affection. And as, after all, the medical man is not quite dead within me, I will confess to you that I have sometimes wondered if she remained as pure in mind, as, most undoubtedly, she did remain in body. However, I think it quite possible, given her sluggish, poor-blooded temperament, not to speak of the innocent sphere in which she grew up, first Bartres, and then the convent. Still, a doubt came to me when I heard of the tender interest which she took in the orphan asylum built by the Sisters of Nevers, farther along this very road. Poor little girls are received into it, and shielded from the perils of the highways. And if Bernadette wished it to be extremely large, so as to lodge all the little lambs in danger, was it not because she herself remembered having roamed the roads with bare feet, and still trembled at the idea of what might have become of her but for the help of the Blessed Virgin?"
