"Certainly the Church does not condemn the efforts of those who want to know the truth, since it is God who made it the nature of man to be most eager to grasp truth. Nor does she condemn the efforts of healthy and right reason, for it is through this reason that we cultivate the spirit, study nature, and bring to light its most hidden secrets. This tender mother recognizes and justly maintains that reason is the most notable of the heavenly gifts, since it is through reason that we raise ourselves above the senses and display a certain image of God in ourselves."
