10. It is true that one may imagine possible worlds without sin and without unhappiness, and one could make some like Utopian or Sevarambian romances: but these same worlds again would be very inferior to ours in goodness. I cannot show you this in detail. For can I know and can I present infinities to you and compare them together? But you must judge with me _ab effectu_, since God has chosen this world as it is. We know, moreover, that often an evil brings forth a good whereto one would not have attained without that evil. Often indeed two evils have made one great good: _Et si fata volunt, bina venena juvant_. Even so two liquids sometimes produce a solid, witness the spirit of wine and spirit of urine mixed by Van Helmont; or so do two cold and dark bodies produce a great fire, witness an acid solution and an aromatic oil combined by Herr Hoffmann. A general makes sometimes a fortunate mistake which brings about the winning of a great battle; and do they not sing on the eve of Easter, in the churches of the Roman rite: _O certe necessarium Adae peccatum, quod Christi morte deletum est!_ _O felix culpa, quae talem ac tantum meruit habere Redemptorem!_ 11. The illustrious prelates of the Gallican church who wrote to Pope Innocent XII against Cardinal Sfondrati's book on predestination, being of the principles of St. Augustine, have said things well fitted to elucidate this great point. The cardinal appears to prefer even to the Kingdom of Heaven the state of children dying without baptism, because sin is the greatest of evils, and they have died innocent of all actual sin. More will be said of that below. The prelates have observed that this opinion is ill founded. The apostle, they say (Rom. iii. 8), is right to disapprove of the doing of evil that good may come, but one cannot disapprove that God, through his exceeding power, derive from the permitting of sins greater goods than such as occurred before the sins. It is not that we ought to take pleasure in sin, God forbid! but that we believe the same apostle when he says (Rom. v. 20) that where sin abounded, grace did much more [130] abound; and we remember that we have gained Jesus Christ himself by reason of sin. Thus we see that the opinion of these prelates tends to maintain that a sequence of things where sin enters in may have been and has been, in effect, better than another sequence without sin.
