3 Following his example, many of you have energetically used these same weapons against your educated enemies by continually studying all the finest sciences and enthusiastically cultivating the liberal arts in order to defend the honor of religion. You were sustained in this by the desire and approval of the popes whose constant preoccupation has always been to preserve the ancient majesty of the arts and to promote the constant progress of culture. You are aware that Our greatest desire has been to see to the proper education of youth. We have everywhere made all possible provisions to ensure it.
