Principlism is an ethical framework that has dominated bioethical discourse for the past 50 years. There are differing perspectives on its proper scope and limits. In this article, we consider to what extent principlism provides guidance for the abortion and euthanasia debates. We argue that whilst principlism may be considered a useful framework for structuring bioethical discourse, it does not in itself allow for the resolution of these neuralgic policy discussions. Scholars have attempted to use principlism to analyse the ethics (...) and legality of abortion and euthanasia; but such efforts are methodologically problematic. We close with a consideration of the proper scope of principlism in bioethics–a vision that is more modest than the manner in which principlism is often deployed in contemporary academic bioethics and medical education.
