Abstract

Privacy is something we all want. We seek privacy to prevent others from securing information about us that is immediately embarrassing, and so causes us pain but not material loss. We also value privacy for strategic reasons in order to prevent others from imposing material and perhaps psychic costs upon us. I use the expression “securing information” so that it covers everything from the immediate sensory data that a voyeur acquires to the financial data a rival may acquire about our businesses. In the degenerate case of the Peeping Tom's invasion of our privacy, suffering is caused just by the voyeur's having acquired the information, even if nothing is ever done with it beyond the voyeur's recalling it from time to time. In all other cases, privacy prevents others from imposing costs or harms on us in ways that require that they secure information about us
