PREFACE

In this edition of my Logic , the text has been revised throughout,
several passages have been rewritten, and some sections added. The chief
alterations and additions occur in cc. i., v., ix., xiii., xvi., xvii.,
xx.

The work may be considered, on the whole, as attached to the school of
Mill; to whose System of Logic , and to Bain's Logic , it is deeply
indebted. Amongst the works of living writers, the Empirical Logic of
Dr. Venn and the Formal Logic of Dr. Keynes have given me most
assistance. To some others acknowledgments have been made as occasion
arose.

For the further study of contemporary opinion, accessible in English,
one may turn to such works as Mr. Bradley's Principles of Logic , Dr.
Bosanquet's Logic; or the Morphology of Knowledge , Prof. Hobhouse's
Theory of Knowledge , Jevon's Principles of Science , and Sigwart's
Logic . Ueberweg's Logic, and History of Logical Doctrine is
invaluable for the history of our subject. The attitude toward Logic of
the Pragmatists or Humanists may best be studied in Dr. Schiller's
Formal Logic , and in Mr. Alfred Sidgwick's Process of Argument and
recent Elementary Logic . The second part of this last work, on the
"Risks of Reasoning," gives an admirably succinct account of their
position. I agree with the Humanists that, in all argument, the
important thing to attend to is the meaning, and that the most serious
difficulties of reasoning occur in dealing with the matter reasoned
about; but I find that a pure science of relation has a necessary place
in the system of knowledge, and that the formulae known as laws of
contradiction, syllogism and causation are useful guides in the framing
and testing of arguments and experiments concerning matters of fact.
Incisive criticism of traditionary doctrines, with some remarkable
reconstructions, may be read in Dr. Mercier's New Logic .

In preparing successive editions of this book, I have profited by the
comments of my friends: Mr. Thomas Whittaker, Prof. Claude Thompson, Dr.
Armitage Smith, Mr. Alfred Sidgwick, Dr. Schiller, Prof. Spearman, and
Prof. Sully, have made important suggestions; and I might have profited
more by them, if the frame of my book, or my principles, had been more
elastic.

As to the present edition, useful criticisms have been received from
