For decades to follow, Charles Van Riper played a pioneering and dominant role in the developing profession of speech- language pathology. Doctor Van Riper was destined to become part of the very fiber of generations of students and practitioners throughout the world, even as he also was to become a source of strength, hope, inspiration, under- standing, and help for countless persons with communication disabilities. "Doctor Van" lived, and urged his students and his colleagues to live, in ways intended to have positive and enduring effects. He sought to teach us that, "although we are specks at the intersection of the two infinities of time and space," we are able to erect a perpendicular at that point. "Every time you help a person to have a better life," he reminds us still, "and every time you've made this earth a bit more beautiful, you add another unit to your perpendicular." Through word and deed he impacted in many ways on myriad lives. He relished the notion thus of "playing bil- liards with eternity." It is in his spirit, and now in remembrance of him, that you are in- vited to explore in these pages the miracle of human speech and hearing, the devastations wrought by their malfunctions, and the still-evolving pro- fessions of speech-language pathology and audiology.

Predentistryand premedicine students also may find in this text usefuloverviews of many of the disability types that they eventually will encounter in their practices. In an introductory textbook it is impossible, of course, to reflectad- equately the ever-expanding roles and responsibilitiesof today's speech- language pathologists and audiologists, so studentswho plan to enter either of these professions will be well advised to supplement theirstud- ies with readings from current journals and specialized texts. Towardthat end we have suggested various sources of more detailed information when our own discussion necessarily is foreshortened. In this ninth edition we have maintained the clinical focus that has helped to make the book uniquely readable, relevant, andinformative for many generations of students. As in previous editions,we have used ac- tual client examples to illustrate and clariFy text material. However, some of the detailed discussions of specific therapy procedures found in earlier editions have been either condensed or eliminated. Chapter 8 is an ex- ception in this regard, representing as it does the seniorauthor's final writ- ings on the treatment of stuttering. In addition to updating information, we have included far more com- prehensive coverage of normal communication processes,and we have expanded considerably our consideration of hearing problemsand audiol- ogy. Some materials have been reorganized (for example,emotional prob- lems associated with speech disorders are discussed in a separate chapter, and alaryngeal speech has been combined with voice disorders in a single chapter); and materials related to professional ethics and scopesof prac- tice have been added as appendices. Among the other new features of this edition are the inclusion of study questions in each chapter and the mar- ginal definition of highlighted glossary terms throughoutthe book. We trust that such changes as well as the improved layout of thisedition will enhance its usefulness to students and instructors alike.
