This anthology of original essays has been nearly .two and one-half
years in the making, and reflects the generous effort of many persons.
To begin with, we thank the contributors to the volume, who not only
cooperated with regards to their own works, but who also provided
valuable advice concerning the over-all volume. One of the contributors
was outstanding in his assistance and warrants special mention: we thank
Professor Michel Meyer, for his encouragement, counsel, and dedication
to see this project to comple- tion. We would also like to thank
Professor Jaakko Hintikka for his encouragement and Mrs. Kuipers of
Reidel for her patience and under- standing along the way. A project
such as this could never have been completed without the unique
assistance of members of the Department of Communication, Ohio State
University: Ms. Kimberly Pasi and Mr. Charles Mawhirtcr. Also, special
thanks are due to our graduate research assistant Ms. Susan Jasko, for
her proofreading and bibliographic work. The pressures of developing a
Festschrift are considerable and could not have been met without the
cooperation and enthusiasm of Mrs. Perelman, especially in allowing us
to publish Professor Perelman's address to Ohio State University as our
introduction.
