This book is based on my doctoral dissertation written at Harvard
University in the year of 1963. My interest in Peirce was inspired by
Professor D. C. Williams and that in Lewis by Professor Roderick Firth.
To both of them lowe a great deal, not only in my study of Peirce and
Lewis, but in my general approach toward the problems of knowledge and
reality. Specifically, I wish to acknowledge Professor Williams for his
patient and careful criticisms of the original manuscripts of this book.
I also wish to thank Professor Firth and Professor Israel Scheffler for
their many suggestive comments regarding my discussions of induc- tion.
However, any error in this study of Peirce and Lewis is completely due
to myself. Chung-ying Cheng Honolulu, Hawaii March,1967 TABLE OF
