This anthology was originally planned in connection with a symposium "Language in Primates: Implications for Linguistics, Anthropology, Psychology, and Philosophy," at Miami University, Oxford, Ohio. Publication of the book would not have been possible without the support given to the Symposium by many individuals and groups. The Editors thank everyone involved for their kind and generous assistance. Specifi cally, we thank the invited speakers at the Symposium, Thomas A. Sebeok, H. Lyn Miles, Roger S. Fouts, and Thomas Simon. The chapters in this book by Miles, Fouts, and Simon are revised versions of their lectures at the Symposium. We thank Edward Simmel for his encouragement, his patience with our efforts, and his help in planning and directing the Symposium. For their financial assistance, we thank the co-sponsors of the Symposium: the Sigma Chi Foundation/William P. Huffman Scholar-in Residence Program at Miami University, as well as the Departments of Classics, Philosophy, Psychology, and Sociology and Anthropology at Miami. We thank Barbara Johnson, Polly J. Harris and Brenda Shaw for their secretarial and editorial help, and Shirley Gallimore for her patience, care, good humor, and hard work in typing the manuscript. Finally, we thank the contributors to this volume."
