 This argument will of course be found unconvincing to many. Some will deny premise (1), either because they reject moral realism as a metaethical stance, or because they reject the normative claim that humans have any kind of special value or dignity. (Maybe they will even think that such a claim is a form of “speciesism.”). Others will find premise (2) suspect. They may be inclined to agree that human persons have a special dignity, but hold that the source of that dignity can be found in such human qualities as rationality. With respect to the status of infants and those suffering from dementia, the critic might bite the bullet and just accept the fact that human dignity does not extend to them, or else argue that the fact that infants and those suffering mental breakdown are part of a species whose members typically possess rationality merits them a special respect, even if they lack this quality as individuals. Others will find premise (2) doubtful because they find the theistic explanation of dignity unclear. Another alternative is to seek a Constructivist account of dignity, perhaps regarding the special status of humans as something we humans decide to extend to each other. Perhaps the strongest non-theistic alternative would be some form of ethical non-naturalism, in which one simply affirms that the claim that persons have a special dignity is an a priori truth requiring no explanation. In effect this is a decision for a non-theistic form of Platonism.
