| Summary: | "The present work aims at embracing a full course of Logic, both Formal and Inductive. In an introductory chapter, are set forth such doctrines of psychology as have a bearing on Logic, the nature of knowledge in general, and the classification of the sciences; the intention being to avoid doctrinal digressions in the course of the work. Although preparatory to the understanding of what follows, this chapter may be passed over lightly on a first perusal of the work. The part on Deduction contains the usual doctrines of the Syllogism, with the additions of Hamilton, and a full abstract of the novel and elaborate schemes of De Morgan and Boole. The Inductive portion comprises the methods of inductive research, and all those collateral topics brought forward by Mr. Mill, as part of the problem of Induction; various modifications being made in the manner of statement, the order of topics, and the proportion of the handling. The greatest innovation is the rendering of Cause by the new doctrine called the Conservation, Persistence, or Correlation of Force"--Preface.
