The document introduces different types of ethical arguments. Definitional arguments define concepts, evaluative arguments evaluate defined concepts, and ethical arguments assess inherent worth based on right vs wrong. Ethical arguments require comparison of ethical systems and must be framed in moral terms. Common ethical systems include naive egoism, which judges based on personal impact; consequentialism, which considers outcomes; and principilism, which adheres to principles regardless of outcomes. These systems provide different bases for determining right and wrong.
