Principles of Argumentation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The principles set forth in this book, the queries answered, I have so often talked over with the assistants who, at Harvard and Wellesley, have aided me in my work, that I feel the results here given are as much theirs as mine. I owe so much in the past, also, to their enthu siasm and their intelligent devotion to their work, that I cannot refrain from recognizing my indebtedness. For valuable suggestions while this book has been going through the press and for reading of the proofs I wish in particular to thank assistant-professor S. C. Hart of Wellesley College, and Mr. F. G. Caffey, of Montgomery, Alabama. For the classification of definitions used on pp. 54 - 59 I am indebted to Professor Genung in his Practical Elm/tents of R/zetorz'c.
