lumen de lumine, was added the Athanasian scholium, Deum verum de Deo vero; and the Trinitarian dogma of the union of persons in a single Godhead became thus the only available logical device for preserving the purity of monotheism. February, 1870. V. A WORD ABOUT MIRACLES. [24] [24] These comments on Mr. Henry Rogers's review of M. Renan's Les Apotres, contained in a letter to Mr. Lewes, were shortly afterwards published by him in the Fortnightly Review, September 15, 1866. It is the lot of every book which attempts to treat the origin and progress of Christianity in a sober and scientific spirit, to meet with unsparing attacks. Critics in plenty are always to be found, who, possessed with the idea that the entire significance and value of the Christian religion are demolished unless we regard it as a sort of historical monstrosity, are only too eager to subject the offending work to a scathing scrutiny, displaying withal a modicum of righteous indignation at the unblushing heresy of the author, not unmixed with a little scornful pity at his inability to believe very preposterous stories upon very meagre evidence. "Conservative" polemics of this sort have doubtless their function. They serve to purge scientific literature of the awkward and careless statements too often made by writers not sufficiently instructed or cautious, which in the absence of hostile criticism might get accepted by the unthinking reader along with the truths which they accompany. Most scientific and philosophical works have their defects; and it is fortunate that there is such a thing as dogmatic ardour in the world, ever sharpening its wits to the utmost, that it may spy each lurking inaccuracy and ruthlessly drag it to light. But this useful spirit is wont to lead those who are inspired by it to shoot beyond the mark, and after pointing out the errors of others, to commit fresh mistakes of their own. In the skilful criticism of M. Renan's work on the Apostles, in No. 29 of the "Fortnightly Review" there is now and then a vulnerable spot through which a controversial shaft may perhaps be made to pierce.
