It was thus that Professor E⁠⸺ learned or recalled the death of my grandmother, and (I must say this to his credit, which is that of the medical profession as a whole), without displaying, without perhaps feeling, any satisfaction. The mistakes made by doctors are innumerable. They err habitually on the side of optimism as to treatment, of pessimism as to the outcome. “Wine? In moderation, it can do you no harm, it is always a tonic.⁠ ⁠… Sexual enjoyment? After all it is a natural function. I allow you to use, but not to abuse it, you understand. Excess in anything is wrong.” At once, what a temptation to the patient to renounce those two life-givers, water and chastity. If, on the other hand, he has any trouble with his heart, albumen, and so forth, it never lasts for long. Disorders that are grave but purely functional are at once ascribed to an imaginary cancer. It is useless to continue visits which are powerless to eradicate an incurable malady. Let the patient, left to his own devices, thereupon subject himself to an implacable regime, and in time recover, or merely survive, and the doctor, to whom he touches his hat in the Avenue de l’Opéra, when he supposed him to have long been lying in Père Lachaise, will interpret the gesture as an act of insolent defiance.
