Textbook of Logic. For Educational Institutions and Self-Education

The study of logic — the science of correct thinking — is one of the essential stages in the formation of an educated and cultured person, especially in our time, when public consciousness is subjected to various kinds of manipulations... based on neglect of logic.
In this regard, the "Textbook of Logic" by the Russian philosopher, logician, and psychologist Georgy Ivanovich Cheltanov (1862–1936) can serve as an excellent aid in studying this ancient and extremely important science. Having gone through several editions before the revolution, it is still popular today. Among its merits are a simple and clear presentation style, an abundance of examples, and explanations of the rules.
The edition is intended for everyone studying and teaching logic — students, graduate students, university instructors, as well as for those who are mastering it independently.
