QUOTE : As regards the soul, many people thought that its nature cannot easily be investigated, and some have even dared say that human reason shows us that the soul dies with the body and that the contrary view is held by faith alone; however, the Lateran Council, held under Leo X (Session 8), condemns them and explicitly commands Christian philosophers to defeat their arguments and prove the truth to the best of their abilities, and therefore I too have not hesitated to take on this challenge.
