The aim of the paper is to show that the privacy of conscious experience is inconsistent with any kind of
physicalism. That is, if you are a physicalist, then you have to deny that more than one subject cannot undergo
the very same conscious experience. In the first part of the paper we define the concepts of privacy and
physicalism. In the second part we delineate two thought experiments in which two subjects undergo the same
kind of conscious experience in such a way that all the physical processes responsible for their experiences are
numerically the same. Based on the thought experiments and their interpretations we present our argument for
the inconsistency of the privacy of experience with physicalism in the third part of the paper. In the final part
we defend our argumentation against some objections.
