" As discussed earlier, humans who lack the reflective self-awareness of normal adults, such as those with particular forms of amnesia or very young children or those with certain mental disabilities, still are self-aware and still have an interest in continuing to live. There may, of course, be a difference between the self-awareness of normal adult humans and that of other animals. But even if that is the case, it does not mean that the latter have no interest in continuing to live, and it does not justify treating the latter as commodities. "
