 A second approach to addressing the problem of moral status for those with significant cognitive disabilities is to emphasize passages in which Kant says all human beings have dignity or are ends in themselves (G 4:428–29; MM 6:410) and to argue that, according to Kant’s theories of biology and psychology, all human beings, including those with severe cognitive disabilities, necessarily have the requisite features of moral personhood (Kain 2009). A third approach is to draw on and perhaps supplement some of Kant’s moral views by, for example, arguing that because we value things, we must value ourselves as ends, which in turn commits us to valuing all human and non-human animals as ends (Korsgaard 2020) or that respect for all human beings is a constitutive feature of rational agency that does not depend on any intrinsic properties of the objects of respect (Sensen 2018).
