First, I introduce the concept of a “non-agential subject,” where a non-agential subject exists within an organism and has phenomenally conscious experiences in a morally significant way, but is not morally responsible for the organism's voluntary actions. Second, I argue that it's a live possibility that typical adult humans contain non-agential subjects. Finally, I argue that, if there are non-agential subjects, this has important and surprising implications for a variety of ethical issues. Accordingly, ethicists should pay more attention to whether (...) there are non-agential subjects and what their implications for ethics would be. (shrink)
