"For many years a mass of documents of interest to Christian Scientists and to their critics as well, has been withheld from publication, although earnestly sought. These documents were written by Dr. P. P. Quimby, of Portland, Maine, and contain his views regarding mental and spiritual healing. They become familiar to Mrs. Mary Baker Eddy when she visited Dr. Quimby as a patient, and it has been charged by her critics that many of the ideas later promulgated in her teachings were born of the Quimby theories. In order to set this controversy at rest, many attempts have been made to gain access to the Quimby manuscripts, but heretofore without success except in piecemeal or disjointed form. The present editor, however, has been fortunate in securing from Mrs. George A. Quimby, owner of the manuscripts, permission to print the documents in full. Many of them now see the light of the printed page for the first time. Others give a full and authentic version of material from which only short extracts have previously appeared."-From the Preface.
