Although these two philosophers share a few similarities in their views, their accounts are starkly contrasting. Marquis could raise several objections to Tooley’s philosophy. In particular, he would question Tooley’s criteria for a right to life. It seems as if Tooley’s criteria essentially entails being self-autonomous and having developed into an adult to some degree- at least to the extent at which one is self aware. Marquis might argue, based on Tooley’s account, that a medical patient who is unconscious and unaware of a possible treatment is undeserving of medical attention, although that may seem contrary to the popular stance. Another criticism he could possibility raise would be against Tooley’s premise that regarding continued personhood.
