Originally published in 1916. This volume from the Cornell University Library's print collections was scanned on an APT BookScan and converted to JPG 2000 format by Kirtas Technologies. All titles scanned cover to cover and pages may include marks notations and other marginalia present in the original volume.
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.
