A Manual of Logic, in Two #245813

This treatise aims at giving a fairly complete view of logical doctrine, as generally accepted at the present time. Of necessity, in a subject where so many conflicting opinions are advanced, some parts of the treatment are somewhat controversial but it is hoped that every view which is criticized is fairly stated. The discussions of disputed points have been mainly confined to the consideration of the theories of logical doctrine advanced in well-known works. It was felt that such a consideration would help in making clear those general principles which can be philosophically justified, and which form the ultimate foundation of the science. A new method of diagrammatically representing categorical propositions is suggested in 5 106, and it is hoped that some freshness of treatment will be found in other parts of the book.
