    An outline of the necessary laws of thought: (1860) PDF book by William Thomson

    An outline of the necessary laws of thought: (1860) PDF book by William Thomson a treatise on pure and applied logic The present work is an attempt to enlarge the science of Pure Logic, so that it may be adequate to the analysis of any act of reasoning. How far it has attained its object ought to be decided by the application of its principles to many miscellaneous examples from different sciences; and whilst I have rigorously and frequently applied this test to it for many years, I cannot hope that the partiality of an author will be a sufficient guarantee of its pretensions, and therefore commend the same line…

It is with hesitation that it is now offered to the public in its present form because it is still growing; but having seen the great advantages which have come to many from the practice of its principles, there arose the…

    How the mind falls into error,( 1923) PDF book:  a brief treatment of fallacies for the general reader by Henry Bradford Smith Excerpt from the author’s preface:Nothing has a higher value in the eyes of the mere teacher attempting to present some subject dry and forbidding in itself, than a fresh illustration; and a teacher of logic is no exception to the rule. Every student in this field who has suffered at the hands of preceptors is familiar with that ancient argument: ” What you bought yesterday, you eat today; you bought raw meat yesterday; therefore, you eat raw meat today.” A well- known writer observes of this case: “This…

    Easy lessons on reasoning by Richard Whately (1872) PDF book

    Download Easy lessons on reasoning by Richard Whately 1872 PDF book The subject treated of in the following pages is one which has not usually been introduced into the course of elementary studies for young persons of all classes. It is supposed by some, that the difference between a better and a worse reasoner depends either wholly on natural ability, or on that combined with practice, or on each man’s greater or less proficiency in the subjects he is treating of. And ‘others again consider a systematic study of the principles of Reasoning as suitable only to a few persons of rare endowments, and of a peculiar turn of mind; and…

    A text-book of logic (1915) by Arthur Ernest Davies

     A text-book of logic (1915) by Arthur Ernest Davies PDF book The time has not arrived when it is possible or desirable to write a text-book of logic for elementary students which departs vary considerably from the course that has been defined by university requirements in various parts of the world. Both in Eu- rope and in America instruction in this subject has to a large extent been controlled by what may be called the classical tradition of which Aristotle and Mill are the two fountain heads. In some quarters this fact has operated as a hardship, and has led to open, if rather one-sided, criticism of the subject’s educational…

I. Mechanical paradoxes.–pt. II. Paradoxes of physical state.–pt. III. Chemical paradoxes.–pt. IV. Physiological paradoxes NATURE is a great conjurer. With many of her tricks, we are so familiar that they do not astonish us; but on giving them a little consideration we often find that they are really very puzzling performances, and we become as eager to learn the explanation as children at a Christmas conjuring party to hear the per- former’s account of how he does it, or children of…

    Fallacies. A view of logic from the practical side (1884) by Alfred Sidgwick PDF book

    Fallacies. A view of logic from the practical side (1884)  by Alfred Sidgwick Excerpt from the introduction:Logic holds what may well be called an uncomfortable position among the sciences. According to some authorities, it cannot be properly said that a body of accepted logical doctrines exists: according to others, the facts and laws that form such doctrine are so completely undeniable that to state them is hard to convey new or important information. Hence, if a writer on the science tries to avoid truism, and so to give practical importance to his statements, there is a danger both of real but crude innovation, and also of over-simple belief in the…

    Logic Free PDF book by Richard F. Clarke (1909) (Laws and Fallacies)

    Logic Free PDF book by Richard F. Clarke (1909) (Laws and Fallacies) Excerpt from the introduction When Scholastic Philosophy ceased to be the subject of systematic study in Protestant Univer- sitieSy and was regarded as possessing a historical rather than scientific interest, there was one branch of it that was treated with less dishonor than the rest. In Ethics and Metaphysics, in Psychology and Natural Theology, the principles handed down by a tradition unbroken for centuries came to be looked upon -as an antique curiosity or as merely illustrating the development of human progress and human thought. These sciences were either set aside as things of the past, consisting of…
