Elementary Lessons In Logic: Deducitve and Inductive

William Stanley Jevons's book was the seminal contribution that educated many generations of English and American scholars that crucial discipline of logic. It teaches the rules for thinking. This was a subject that every student once had to take, and not in college but quite early in life, and certainly by high school. No more. Today, it is widely assumed that there is no structure of thinking that is worth studying. And perhaps that explains why serious thinking is so rare. It is nothing short of astonishing that most people go all the way through school with no exposure to logic at all. This book is not easy. It takes patience and discipline. It offers a great challenge to anyone. However, if you can go through the book and learn from it, you will have a massive advantage over colleagues, most of whom have never studied this area.
