The fourth edition of Inviting Transformation continues to offer an innovative approach to presentational speaking at a very reasonable price. The authors introduce readers to invitational rhetoric, teaching speakers to clarify ideas and to work to achieve understanding for all participants in an interaction. A primary goal of presentational speaking is to create an environment in which growth and change can occur for both the audience and the speaker. The text highlights four external conditions affecting transformational environments: safety, openness, freedom, and value (honoring the intrinsic worth of all individuals).To reflect respect for the diversity of the world, Sonja Foss and Karen Foss include options from many speaking traditions and practices to foster creativity. Discussions of all the processes of presenting- selecting a speaking goal, organizing ideas, elaborating on ideas, and delivering the presentation-emphasize inclusive speaking practices. Sample presentations provide clear and contemporary examples of the best invitational speaking practices.The authors recognize readers as competent communicators and encourage them to think about and systematize their approaches to presentational speaking. The exceptionally accessible writing style is an aid to readers in thinking through strategies for meeting their interactional goals. Readers learn to design and deliver effective presentations for any speaking situation.
