Abstract
Many pro-life supporters accept the substance view of human value, tying intrinsic value to properties essential to all human beings. Many pro-choice supporters accept the functionalist view of human value, tying intrinsic value to accidental functional properties. They argue that there are circumstances in which terminating human beings is permissible. I offer three reasons for rejecting FV. First, FV fails to ontologically ground intrinsic qualities. Second, FV entails that technologically enhanced human beings may have greater intrinsic value than unenhanced human beings. Third, FV entails a problematic pragmatic-utilitarian view of value that undermines widespread convictions about human dignity.
