The testimony concerning Lincoln's religious belief presented in this volume has been derived chiefly from three sources. 1. A part of it has been gathered from the works above named. In a single volume is published for the first time matter which heretofore was only to be found scattered through numerous volumes, some of them inaccessible to the general reader. 2. A considerable portion of it has been gleaned from newspapers and periodicals containing statements brought out by this controversy, many of which would otherwise soon be lost or forgotten. 3. A very large share of it has been obtained by the writer from personal friends of Lincoln; and when we realize how rapidly those who lived and moved with him are passing away--that erelong none of them will remain to testify--the importance of this evidence can hardly be overestimated. The writer believes that he has fully established the negative of the proposition that forms the title of his book. He does not expect to silence the claims of the affirmative; but he has furnished an arsenal of facts whereby these claims may be exposed and refuted as often as made. This effort to prove that Lincoln was not a Christian will be condemned by many as an attempt to fasten a stain upon this great man's character. But the demonstration and perpetuation of this fact will only add to his greatness. It will show that he was in advance of his generation. The fame of Abraham Lincoln belongs not to this age alone, but will endure for all time. The popular faith is transient and must perish. It is unpopular now to reject Christianity, but the day is fast approaching when to accept its dogmas will be considered an evidence of human weakness. To perpetuate the claim that Lincoln was a Christian is to perpetuate an idea that in a future age will lessen the luster of his name. It will be urged by some that the intent and purpose of this work is solely to promote the interests of Freethought. But it is not. The writer advocates no cause that requires the prestige of a great name to make it respectable. The cause that requires the indorsement of the great to sustain it is not worthy to survive. He has prosecuted this investigation, not in the interest of any belief or creed, but in the interest of truth; and truth is certainly as high as any creed, even if that creed be true. In proving Lincoln a disbeliever he does not presume to have proved Christianity false, or Freethought true; but he has shown that some Christians are not honest, and that an honest man may be a Freethinker. Atchison, Kan., April, 1893. INTRODUCTION. Was Abraham Lincoln a Christian? Many confidently believe and earnestly contend that he was; others as confidently believe and as earnestly contend that he was not.
