The previous chapters have focused on the First Amendment’s protection for freedom of speech (and unexpressed thought and knowledge creation) as possible bases for a right to use our perception to observe the world—and to augment that perception. This chapter takes a different approach. It begins with a right that different provisions of the Constitution (the Fourth, Fifth, and Fourteenth Amendments) give us: a right (or rights) to bodily freedom and personal integrity. It then points out that these provisions should not only shield our bodies and persons but more broadly shield the prosthetics we use to replace lost body functions, as well as other technologies we integrate into our bodies (and perhaps, make a part of our minds). The challenge arises when we explore extending such protection to technologies that aren’t restorative and integrated into us—but rather are at a further remove and enhance our vision. These extensions may seem less integral to our autonomy and may also threaten other interests in the world.
