 Some support for this criticism of the attempt to see reason as the basis of the value of humans can be found in Nicholas Wolterstorff’s recent work on justice (2007, especially Ch. 8). Wolterstorff in this work defends the claim that there are natural human rights, and that violating such rights is one way of acting unjustly towards a person. Why do humans have such rights? Wolterstorff says these rights are grounded in the basic worth or dignity that humans possess. When I seek to torture or kill an innocent human I am failing to respect this worth. If one asks why we should think humans possess such worth, Wolterstorff argues that the belief that humans have this quality was not only historically produced by Jewish and Christian conceptions of the human person, but even now cannot be defended apart from such a conception. In particular, he argues that attempts to argue that our worth stems from some excellence we possess such as reason will not explain the worth of infants or those with severe brain injuries or dementia.
