Elementary Lessons in Logic: Deductive and Inductive, written by William Stanley Jevons in 1870, is a comprehensive guide to the study of logic.
The book is divided into three main parts, with the first part focusing on the definition and scope of the science of logic.
In the second part of the book, Jevons delves into the various aspects of terms, which are the building blocks of logical reasoning.
He discusses the different kinds of terms and explores the ambiguity that can arise from the use of language. Jevons also examines the dual nature of terms, looking at how they can have both extension and intension.
The third part of the book is dedicated to propositions, which are statements that can be either true or false.
Jevons explains the different kinds of propositions and how they can be opposed to one another.
He also covers the conversion of propositions and immediate inference, which are important concepts in logical reasoning.
Throughout the book, Jevons draws on the work of philosophers such as Leibnitz to provide a deeper understanding of logic and knowledge. He also discusses the evolution of language and how it influences our ability to reason logically.
Elementary Lessons in Logic is a valuable resource for anyone looking to improve their understanding of deductive and inductive reasoning.
Jevons' clear and concise explanations make complex concepts accessible to readers of all levels, making this book a must-read for students and scholars alike.
