Privacy and perfect voyeurism

I argue that there is nothing wrong with perfect voyeurism, covert watching or listening that is neither discovered nor publicized. After a brief discussion of privacy I present attempts from Stanley Benn, Daniel Nathan, and James Moor to show that the act is wrong. I argue that these authors fail to make their case. However, I maintain that, if detected or publicized, voyeurism can do grave harm and to that extent should be severely punished. I conclude with some thoughts on the stubborn intuition that perfect voyeurism is wrong despite the absence of harm.
