Life Leads to the Knowledge of Truth

Such a combination of doctrine and piety, of erudition and virtue, of truth and charity, is to be found in an eminent degree in the angelic Doctor and it is not without reason that he has been given the sun for a device; for he both brings the light of learning into the minds of men and fires their hearts and wills with the virtues. God, the Source of all sanctity and wisdom would, therefore, seem to have desired to show in the case of Thomas how each of these qualities assists the other, how the practice of the virtues disposes to the contemplation of truth, and the profound consideration of truth in turn gives luster and perfection to the virtues. For the man of pure and upright life, whose passions are controlled by virtue, is delivered as it were of a heavy burden and can much more easily raise his mind to heavenly things and penetrate more profoundly into the secrets of God, according to the maxim of Thomas himself: “Life comes before learning: for life leads to the knowledge of truth” (Pius XI: St. Thomas Aquinas)
