Doctor Pascal by Émile Zola

Dr. Pascal then resumed his professional visits in the town and the surrounding country. And he was generally accompanied by Clotilde, who went with him into the houses of the poor, where she, too, brought health and cheerfulness.

But, as he had one night confessed to her in secret, his visits were now only visits of relief and consolation. If he had before practised with repugnance it was because he had felt how vain was medical science. Empiricism disheartened him. From the moment that medicine ceased to be an experimental science and became an art, he was filled with disquiet at the thought of the infinite variety of diseases and of their remedies, according to the constitution of the patient. Treatment changed with every new hypothesis; how many people, then, must the methods now abandoned have killed! The perspicacity of the physician became everything, the healer was only a happily endowed diviner, himself groping in the dark and effecting cures through his fortunate endowment. And this explained why he had given up his patients almost altogether, after a dozen years of practise, to devote himself entirely to study.
