Consciousness, the brain and what matters.

Grant Gillett argues that it is consciousness which makes a human or other being the 'locus of ethical value'. Since cortical functioning is, in Gillett's view, necessary for conscious activity, an individual whose neocortex is permanently non-functional is no longer a locus of ethical value and cannot be benefited or harmed in a morally relevant sense. This means that there is no obligation to continue treating those who have suffered neocortical death.
