Privacy | Stanford Encyclopedia of Philosophy - http://plato.stanford.edu/entries...
"The term “privacy” is used frequently in ordinary language as well as in philosophical, political and legal discussions, yet there is no single definition or analysis or meaning of the term. The concept of privacy has broad historical roots in sociological and anthropological discussions about how extensively it is valued and preserved in various cultures. Moreover, the concept has historical origins in well known philosophical discussions, most notably Aristotle's distinction between the public sphere of political activity and the private sphere associated with family and domestic life. Yet historical use of the term is not uniform, and there remains confusion over the meaning, value and scope of the concept of privacy. Early treatises on privacy appeared with the development of privacy protection in American law from the 1890's 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. " - Amira
"This essay will discuss all of these topics, namely, (1) the historical roots of the concept of privacy, including the development of privacy protection in tort and constitutional law, and the philosophical responses that privacy is merely reducible to other interests or is a coherent concept with fundamental value, (2) the critiques of privacy as a right, (3) the wide array of philosophical definitions or defenses of privacy as a concept, providing alternative views on the meaning and value of privacy (and whether or not it is culturally relative), as well as (4) the challenges to privacy posed in an age of technological advance." - Amira
