  The difficulty with (6*)–(8*), I think, is that (8*) does not stipulate what it is about yourself that you are required to value, so that this could be my sheer particularity (self-conceit), or if I am not in fact human, my non-human nature (Satan). This is because (6*) just identifies a need, and says that this need could not be important unless the agent who has the need were seen to be valuable somehow – whereas the previous argument narrows value down to rational agency, and so rules out both self-conceit and devilishness.
