An Alternative to the Rational Substance Pro-life View

Abstract

The Rational Substance View is a pro-life position which maintains that all humans are moral equals and have a right to life in virtue of their kind membership. Healthy embryos, newborns, children, adults, and as the cognitively impaired all essentially have a root or radical capacity for rationality, though it may not be developed or have its operations blocked. Their being substances with a rational nature is the basis of their moral status and what makes it wrong to kill them. I will argue that the view is committed to some bad biology, and suspect metaphysics, and is unable to escape all the reductios of potentiality. I will offer the Healthy Development View as an alternative to the Rational Substance View. It is a pro-life view that avoids the problematic biology and metaphysics and reductios of potentiality. It understands our rational development to be a contingent rather than an essential trait.
