THESE pages are a modest contribution towards the accomplishment of an important purpose. They are written in compliance with an earnest desire repeatedly expressed in the solemn utterances of our venerated Supreme Pontiff Leo XIII. "The more active," he says, "the enemies of religion are to teach the unlearned, the young especially, what clouds their intellect and corrupts their morals, the more should you exert yourselves to establish not only a well-adapted and solid method of instruction, but a method in perfect conformity with the Catholic faith, especially as regards Mental Philosophy, on which the right teaching of all the other sciences in a great measure depends -- a Philosophy which shall prepare the way for Divine Revelation instead of aiming at its overthrow.
This book was truly great for critical logic and mental philosophy, here are my pros and cons.
Pros: He explains critical logic very concisely, with much detail, and interacts with different schools of thought on various occasions. His work on mental philosophy is very good for a beginner and he explains these concepts well. Fr. Coppens is well suited for beginners
Cons: Many printing errors such as misspelled words, missing letters, distortions in the text etc.
Fr.Coppens as a jesuit defends middle knowledge (cringe, read Fr Billuart’s refutation translated by Christian B Wagner)
Very anti evolution of all types (including theistic evolution) however it is worthy of mention that this was written in 1891, before modern evolutionary science.
Overall: Great book and I definitely recommend it for any level of reader!
