  Early treatises on privacy appeared with the development of privacy protection in American law from the 1890s onward, and privacy protection was justified largely on moral grounds. This literature helps distinguish descriptive accounts of privacy, describing what is in fact protected as private, from normative accounts of privacy defending its value and the extent to which it should be protected. In these discussions some treat privacy as an interest with moral value, while others refer to it as a moral or legal right that ought to be protected by society or the law. Clearly one can be insensitive to another’s privacy interests without violating any right to privacy, if there is one.
