Some evil actions are public. Maybe genocide is the most awful. Other evil actions are private, a matter of one person harming another or of self-inflicted injury. Child abuse, in our current reckoning, is the worst of private evils. We want to put a stop to it. We know we can’t do that, not entirely. Human wickedness won’t go away. But we must protect as many children as we can. We want also to discover and help those who have already (...) been hurt. Anyone who feels differently is already something of a monster.We are so sure of these moral truths that we seldom pause to wonder what child abuse is. We know we don’t understand it. We have little idea of what prompts people to harm children. But we do have the sense that what we mean by child abuse is something perfectly definite. So it comes as a surprise that the very idea of child abuse has been in constant flux the past thirty years. Previously our present conception of abusing a child did not even exist. People do many of the same vile things to children, for sure, that they did a century ago. But we’ve been almost unwittingly changing the very definitions of abuse and revising our values and our moral codes accordingly.

is a term introduced by Ian Hacking to refer to the kinds of people—child abusers, pregnant teenagers, the unemployed—studied by the human sciences. Hacking argues that classifying and describing human kinds results in feedback, which alters the very kinds under study. This feedback results in human kinds having histories totally unlike those of natural kinds (such as gold, electrons and tigers), leading Hacking to conclude that human kinds are radically unlike natural kinds. Here I argue that Hacking's argument fails and (...) that he has not demonstrated that human kinds cannot be natural kinds.
