Valuable as this volume is to the careful student for its erudition and acute reasoning, and for the aid it gives in the polemical controversies that rise from time to time with Protestants, it is chiefly valuable, in our eyes, as a well-reasoned and, as it were, practical refutation of that rationalistic or materialistic system of false philosophy which is taught in some of our colleges, and is being spread through the land, and which either leaves God out of sight altogether, or at most acknowledges him only as the Creator and founder of the physical order. Dr. Newman, in discussing what some would term the philosophy of miracles, sets forth strongly and clearly the necessity of recognizing and taking into account the moral order, established by God, equally with the physical order, and superior to it in rank. The world is under both. To leave either out is to take only a partial view. To exclude the moral order from our consideration is to err at the very commencement of our course, and our progress will be but from error to error. The action of both orders may, and often does, coincide--would have always coincided had not sin brought in jarring and confusion. But in point of fact, they are sometimes found in opposition. A wise and good sovereign dies immaturely, leaving his sceptre to a wicked and unscrupulous successor; a good father dies early in life, and his orphans are left to grow up in ignorance and vice; a just and benevolent man dies or is ruined, and debts are left unpaid, and a stream of charity fails at the fount. And if we class the evil actions of men as belonging to this physical order, and the rationalists refuse to class them otherwise, do they not present a continual opposition between the physical and the moral orders? And if the physical order so asserts itself, should we not reasonably look for corresponding, if not greater, manifestations in the moral order?
