This is a challenging read, and as such is perhaps an indication of what we've lost, academically, over the past century in terms of challenge. The original edition of this book dates back to around the turn of the 20th century; the edition I read dates from some time after WWI. I would regard this as a must for anyone interested in any kind of deep debate on any topic. My biggest gripe is that the section on Fallacies is relegated to an appendix.
