Couldn't all the arguments that a foetus is not a person be applied to someone who is asleep? If you gave someone a powerful drug that caused them to fall into a deep, dreamless sleep, they would not be conscious, they wouldn't feel pain, they wouldn't have any emotions, they lack rational thought and free ability, preferences, sense of identity etc. It doesn't seem to matter that sleep is temporary, as being a foetus is also a temporary state. Do we all cease to be persons for eight hours every night? Is it acceptable to a being that is asleep or otherwise unconscious, under the abortionist view?
