Chekhov on judges, police officers, and doctors

From his story, Ward No. 6:

People who have an official, professional relation to other men’s sufferings–for instance, judges, police officers, doctors–in course of time, through habit, grow so callous that they cannot, even if they wish it, take any but a formal attitude to their clients; in this respect they are not different from the peasant who slaughters sheep and calves in the back-yard, and does not notice the blood.
