This document provides an overview of ethical models and applied ethics. It discusses several key points: 1) Applied ethics focuses on the practical application of moral issues to clarify, organize, and refine moral ideas in order to enrich moral experience and guide judgment. 2) There are two main theoretical categories of ethics: consequential (e.g. utilitarianism) and non-consequential (e.g. Kant's categorical imperative). 3) All ethical models have limitations and weaknesses, and determining what is ethical in reality utilizes aspects of multiple models rather than just one alone.
