  Theorists including William Parent (1983) and Judith Thomson (1975) argue that the constitutional right to privacy is not really a privacy right, but is more aptly described as a right to liberty. Other commentators believe, to the contrary, that even if Douglas’ opinion is flawed in its defense, using vague language about a penumbral privacy right emanating from the Constitution and its Amendments, there is nevertheless a historically and conceptually coherent notion of privacy, distinct from liberty, carved out by the constitutional privacy cases (Inness, 1992; Schoeman, 1992; Johnson, 1994; DeCew, 1997).
