Communication has been called the most practical of the academic disciplines. Even the most theoretical and philosophical communication scholars are also practitioners of communication, and even though you have likely never taken another communication studies class, you have a lifetime of experience communicating. This experiential knowledge provides a useful foundation and a starting point from which you can build the knowledge and practice the skills necessary to become a more competent and ethical communicator. I always inform my students that I consider them communication scholars while they are taking my class, and I am pleased to welcome you to the start of your communication studies journey. Whether you stay on this path for a semester or for much longer, studying communication has the potential to enrich your life in many ways. I want this book to be a dialogue, so I encourage you to contact me with any questions, comments, or suggestions you may have as you read.
