May we not return to those scoundrels of old, the illustrious founders of superstition and fanaticism, who first took the knife from the altar to make victims of those who refused to be their disciples?
Ne peut-on pas remonter jusqu'à ces anciens scélérats, fondateurs illustres de la superstition et du fanatisme, qui, les premiers, ont pris le couteau sur l'autel pour faire des victimes de ceux qui refusaient d'etre leurs disciples?
