Logic Texts

William Stanley Jevons, the Englishman who discovered the subjective theory of value simultaneously with Austrian Karl Menger and Frenchman Léon Walras, wrote a book called Elementary Lessons in Logic, which he considered an introduction to John Stuart Mill's A System of Logic, Ratiocinative and Inductive.

The latter was highly recommended by Dr. James Hall, whose course, Tools of Thinking I bought from The Teaching Company and the latter is on sale now by The Mises Institute.

I set myself the task of reading them.
