The aim I have had in view in writing this book has been to give a history of the origin of Unitarianism in the United States, how it has organized itself, and what it has accomplished. It seemed desirable to deal more fully than has been done hitherto with the obscure beginnings of the Unitarian movement in New England; but limits of space have made it impossible to treat this phase of the subject in other than a cursory manner. It deserves an exhaustive treatment, which will amply repay the necessary labor to this end. The theological controversies that led to the separation of the Unitarians from the older Congregational body have been only briefly alluded to, the design of my work not requiring an ampler treatment. It was not thought best to cover the ground so ably traversed by Rev. George E. Ellis, in his Half-century of the Unitarian Controversy; Rev. Joseph Henry Allen, in his Our Liberal Movement in Theology; Rev. William Channing Gannett, in his Memoir of Dr. Ezra Stiles Gannett; and by Rev. John White Chadwick, in his Old and New Unitarian Beliefs. The attempt here made has been to supplement these works, and to treat of the practical side of Unitarianism,--its organizations, charities, philanthropies, and reforms.

With the theological problems involved in the history of Unitarianism this volume deals only so far as they have affected its general development. I have endeavored to treat of them fairly and without prejudice, to state the position of each side to the various controversies in the words of those who have accepted its point of view, and to judge of them as phases of a larger religious growth. I have not thought it wise to attempt anything approaching an exhaustive treatment of the controversies produced by the transcendental movement and by "the Western issue." If they are to be dealt with in the true spirit of the historical method, it must be at a period more remote from these discussions than that of one who participated in them, however slightly. I have endeavored to treat of all phases of Unitarianism without reference to local interests and without sectional preferences. If my book does not indicate such regard to what is national rather than to what is provincial, as some of my readers may desire, it is due to inability to secure information that would have given a broader character to my treatment of the subject.

The present work may appear to some of its readers to have been written in a sectarian spirit, with a purpose to magnify the excellences of Unitarianism, and to ignore its limitations. Such has not been the purpose I have kept before me; but, rather, my aim has been to present the facts candidly and justly, and to treat of them from the standpoint of a student of the religious evolution of mankind. Unitarianism in this country presents an attempt to bring religion into harmony with philosophy and science, and to reconcile Christianity with the modern spirit. Its effort in this direction is one that deserves careful consideration, especially in view of the unity and harmony it has developed in the body of believers who accept its teachings. The Unitarian body is a small one, but it has a history of great significance with reference to the future development of Christianity.

The names of those who accept Unitarianism have not been given in this book in any boastful spirit. A faith that is often spoken against may justify itself by what it has accomplished, and its best fruits are the men and women who have lived in the spirit of its teachings. In presenting the names of those who are not in any way identified with Unitarian churches, the purpose has been to suggest the wide and inclusive character of the Unitarian movement, and to indicate that it is not represented merely by a body of churches, but that it is an individual way of looking at the facts of life and its problems.

In writing the following pages, I have had constantly in mind those who have not been educated as Unitarians, and who have come into this inheritance through struggle and search. Not having been to the manner born myself, I have sought to provide such persons with the kind of information that would have been helpful to me in my endeavors to know the Unitarian life and temper. Something of what appears in these pages is due to this desire to help those who wish to know concretely what Unitarianism is, and what it has said and done to justify its existence. This will account for the manner of treatment and for some of the topics selected.

When this work was begun, the design was that it should form a part of the exhibit of Unitarianism in this country presented at the seventy-fifth anniversary of the formation of the American Unitarian Association. The time required for a careful verification of facts made it impossible to have the book ready at that date. The delay in its publication has not freed the work from all errors and defects, but it has given the opportunity for a more adequate treatment of many phases of the subject. Much of the work required in its preparation does not show itself in the following pages; but it has involved an extended examination of manuscript journals and records, as well as printed reports of societies, newspapers, magazines, pamphlets, and books. Many of the subjects dealt with, not having been touched upon in any previous historical work, have demanded a first-hand study of records, often difficult to find access to, and even more difficult to summarize in an interesting and adequate manner.

I wish here to warmly thank all those persons, many in number and too numerous to give all their names, who have generously aided me with their letters and manuscripts, and by the loan of books, magazines, pamphlets, and newspapers. Without their aid the book would have been much less adequate in its treatment of many subjects than it is at present. Though I am responsible for the book as it presents itself to the reader, much of its value is due to those who have thus labored with me in its preparation. In manuscript and in proof-sheet it has been read by several persons, who have kindly aided in securing accuracy to names, dates, and historic facts.
