Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1892 edition. Excerpt: ... chapter xxl the laws of thought The Laws of Thought do not require any elaborate treatment in an elementary treatise upon Logic, but the manner in which they have been assumed, or in which they underlie all our reasonings makes it necessary to state them and their meaning very briefly. We have already explained what a "law of thought" means, in our statement that it denotes the uniform way in which we think and must think. In all our reasoning we take tbese laws for granted. They are condi" tions of our reasoning and of the relation expressed between subject and predicate, antecedent and consequent, in propositions. We do not require to announce them as premises in our processes of transition from proposition to proposition, because they are either universally assumed without question, or they are the conditions of the formal and material truth of the data themselves, which it is not the business of formal Logic to investigate. Besides, they are of that axiomatic nature which renders it necessary to admit them before we could construct an objection or an argument against them. We do not require, therefore, to investigate them to determine their validity, but only to state what they are, their meaning and their functions. The Laws of Thought may be divided into two classes, the Primary or Fundamental, and the Secondary or Derived. The primary laws are those which regulate all thought, whatever, whether of Conception, Judgment, or Reasoning. The secondary are simply those modified forms of the primary laws which are formulated in a particular way to suit the contingencies of syllogistic reasoning. We shall consider them in their order. 1st. The Primary Laws.--As defined, they are the fundamental laws of all thinking; that is, of conceiving...

Book Description
Excerpt from Logic, Theoretical and Practical It is now some fifteen years since I published "An Elementary Treatise on Logic," which in its third edition is still before the public. I would not, however, have the reader regard this Book as merely a compilation, condensation, abridgement or re-arrangement of the former Work. On the contrary, it differs from it in many essential particulars. Since the time of the publication of that Treatise, my attention has been chiefly directed to the study of the Principles and Forms of reasoning, as they occur in the actual practice of men who are engaged in the various intellectual processes that are called for in the prosecution of the affairs of life, and I am able to offer here a Work, which, I think, will be found, in many respects, to be especially worthy of attention.

Book Description
From the PREFACE. It is now some fifteen years since I published "An Elementary Treatise on Logic," which in its third edition is still before the public. I would not, however, have the reader regard this Book as merely a compilation, condensation, abridgement or re-arrangement of the former Work. On the contrary, it differs from it in many essential particulars. Since the time of the publication of that Treatise, my attention has been chiefly directed to the study of the Principles and Forms of reasoning, as they occur in the actual practice of men who are engaged in the various intellectual processes that are called for in the prosecution of the affairs of life, and I am able to offer here a Work, which, I think, will be found, in many respects, to be especially worthy of attention. It has been customary to regard Logic as a mere formal or instrumental science, dealing with "ideas," "notions" or "conceptions," as something intermediate between the mind that perceives and reasons, and the substantial objects which it perceives and reasons about. I have fully adopted and carried out Cousin's declaration. "If by ideas is understood something real which exists independently of language, and is intermediate between the mind and things that exist, 1 say that there are no ideas. There is nothing real, except things and the mind with its operations." I hold, therefore, that Logic deals with Things, and hot any mere fictions, under whatever name they may be designated, whether "ideas," "notions," "concepts" or whatnot. And it uses words as representing things; and sentences or propositions as representing the relations which things appear to sustain to each other. What those relations really are, is a question that belongs to a higher department of metaphysics, Ontology. This view of the nature of Logic has enabled me to simplify my discussions of the Formulae very greatly, to dispense with an immense amount of technicalities, and by constantly referring to things instead of mere "notions" about them, it has" enabled me to make the general principles and laws of reasoning much simpler and more easily comprehensible. This view of the nature of Logic and of the functions of language in relation to it has led to, and rendered possible, a much more satisfactory account of the Fallacies, especially those in Diction, than has hitherto been attained. I think I have now made a classification that has enabled me to give an account of them that is clear, complete and satisfactory....

Book Description
Originally published in 1965. This is a textbook of modern deductive logic, designed for beginners but leading further into the heart of the subject than most other books of the kind. The fields covered are the Propositional Calculus, the more elementary parts of the Predicate Calculus, and Syllogistic Logic treated from a modern point of view. In each of the systems discussed the main emphases are on Decision Procedures and Axiomatisation, and the material is presented with as much formal rigour as is compatible with clarity of exposition. The techniques used are not only described but given a theoretical justification. Proofs of Consistency, Completeness and Independence are set out in detail. The fundamental characteristics of the various systems studies, and their relations to each other are established by meta-logical proofs, which are used freely in all sections of the book. Exercises are appended to most of the chapters, and answers are provided.
