The document provides an overview and comparison of three ethical frameworks: natural law, virtue ethics, and situation ethics. It discusses the perspectives of philosophers like Cicero, Aquinas, and Aristotle in developing natural law and virtue ethics. For situation ethics, it outlines the perspective of Joseph Fletcher who argued that love should be the single principle to judge situations rather than absolute rules. The document then provides potential pros and cons of each approach and asks the reader to apply them to the ethical issue of abortion.
