A digest of deductive logic for the use of students
 |
| A digest of deductive logic -by Johnson Barker |
This book does not pretend to be a treatise. It is a notebook, intended to be used side by side with the ordinary Manual. My indebtedness to the ordinary Manual, as may be supposed, is con- siderable, for in large part these notes are little more than a summary of what any ordinary manual will contain: to summarise, however, was my main purpose.
The book is designed, as stated in the title, for students preparing for the examination. It offers them, firstly, an outline of that portion of the subject which the textbook treats in full; and, secondly, it provides a somewhat fuller discussion of points that are apt to be overlooked or omitted. It has been my aim throughout to bring into the relief of bare outline the essentials of deduction and to elucidate obscurities.
This book, then, differs from other works in being condensed where they are full, and in being supplementary where they are condensed, and thus it may claim a certain sort of freshness of treatment.
These notes have already been found useful in teaching. It is hoped that their usefulness may be extended by publication. The questions in Appendix I. are selected mainly from the B.A. examination papers set at the Universities of London and Durham.
They are arranged, as far as possible, in sets corresponding- ing to the subject matter of the chapters to which the Roman numerals refer.
The number of questions might easily have been multiplied: their purpose here, however, is not so much to supply an exhaustive praxis but to indicate, all along the line of the study, the general standard required of those who take up Logic for examination. The Bibliography in Appendix II. is not in any sense complete. It is a list compiled in the course of my own reading, which for purposes of reference from time to time I have found useful. It is more complete than any similar list with which I am acquainted.
