Ethics are not heavily emphasized in either public speaking textbooks or classroom lectures. This de-emphasis of public speaking ethics is unfortunate. Educators should take responsibility for making sure that students are familiar with ethical issues and that they know that unethical public communication is not acceptable. Since public speaking textbooks do not provide much explicit guidance for ethical decision making, supplementary material is provided in this article. Four ethical principles are provided to help students understand the nature of communication ethics, a sample class lecture is outlined, and teaching ideas are included.
