The disbelief of immortality was however too obvious a temptation in a corrupt age, as well as too generally spread, especially in the next century, to be wholly attributable to the subtle influence of the doctrine of absorption of the Arabic philosophy. A mediæval English poet(297) attributes incredulity to the higher classes of his age; and Dante, in that poem which is a romantic picture of his contemporaries or predecessors, when devoting one circle of the Inferno to the habitation of the “more than a thousand” of those “who make the soul die with the body,” attributes the cause of the sin to Epicureanism, a moral and not an intellectual cause.(298) It is a sad and humiliating thought to reflect also that a cause which must have increased incredulity, if it did not create it, was to be found in the vices of the clergy, especially near the papal court of Avignon. Most of the distinguished laymen whom history records as evincing unbelief belonged to the political party, which strove to repress the political centralization and temporal authority of the church; and it is to be feared that the causes just named were the means of repelling more deeply from religion the hearts of such persons whose interests or whose vices already led them to hate its promoters.(299) We have thus collected the few traces which mark the history of free thought in the second great crisis of church history, and incidentally illustrated its connexion with social movements as well as religious, and shown its relation to intellectual or moral causes. On the intellectual side we have witnessed the scholastic philosophy giving activity to the spirit of change, and contact with Mahometan life and opinion imparting the latitude to Christian thought which passed into incredulity. On the moral we have noticed that the effect of social wants or of actual viciousness gave birth respectively to religious restlessness, or to actual disbelief of the supernatural. The church of the time was not unaware of the movement. In part it tried to repress it by persecution and by the Inquisition; but in part also by the lawful weapon of spiritual contest. The grand works of defence of the thirteenth century, which adjusted scholastic philosophy to dogmatic theology, and the spiritual activity of the mendicant orders, were real and lawful means of victory, appealing respectively to the intellect and heart.
