Many theorists have expressed the view that current or future applications of neurotechnology may prompt serious ethical problems in terms of privacy. This article concerns the question as to whether involuntary neurotechnological mind reading can plausibly be held to violate a person’s moral right to mental privacy. It is argued that it is difficult to specify what a violation of a right to mental privacy amounts to in a way that is consistent with the fact that we usually regard natural mind reading as morally unproblematic.
