Abstract
Gewirth's view that ethics is based on human rights is contrasted to Blanshard's view that human rights derive their support from ethics. For Blanshard intrinsic good is comprised of whatever both satisfies and fulfills human nature. Human rights and correlated duties depend entirely upon whether or not they foster this intrinsic good. For Gewirth, by contrast, human claim-rights, such as freedom and well-being, are the foundation of human agency required for moral action of any sort. Such rights, properly conceived, are the foundation and basis of ethics
