of an honest writer. After a time the writer has cooled down from his excitement,—has got over his apprehensions, is pleased to find that his book is still read, and that he must write a new Preface. He comes smiling to his task. How many things have explained themselves in the ten or twenty or thirty years since he came before his untried public in those almost plaintive paragraphs in which he introduced himself to his readers,—for the Preface writer, no matter how fierce a combatant he may prove, comes on to the stage with his shield on his right arm and his sword in his left hand. The Professor at the Breakfast-Table came out in the “Atlantic Monthly” and introduced itself without any formal Preface. A quarter of a century later the Preface of 1882, which the reader has just had laid before him, was written. There is no mark of worry, I think, in that. Old opponents had come up and shaken hands with the author they had attacked or denounced. Newspapers which had warned their subscribers against him were glad to get him as a contributor to their columns. A great change had come over the community with reference to their beliefs. Christian believers were united as never before in the feeling that, after all, their common object was to elevate the moral and religious standard of humanity. But within the special compartments of the great Christian fold the marks of division have pronounced themselves in the most unmistakable manner. As an example we may take the lines of cleavage which have shown themselves in the two great churches, the Congregational and the Presbyterian, and the very distinct fissure which is manifest in the transplanted Anglican church of this country. Recent circumstances have brought out the fact of the great change in the dogmatic communities which has been going on silently but surely. The licensing of a missionary, the transfer of a Professor from one department to another, the election of a Bishop,—each of these movements furnishes evidence that there is no such thing as an air-tight reservoir of doctrinal finalities. The folding-doors are wide open to every Protestant to enter all the privileged precincts and private apartments of the various exclusive religious organizations. We may demand the credentials of every creed and catechise all the catechisms. So we may discuss the gravest questions unblamed over our morning coffee-cups or our evening tea-cups. There is no rest for the Protestant until he
