THE long-looked-for, much-coveted volume of SCIENCE AND HEALTH, that is to mark an epoch in the Christian Science movement, has at last appeared; and will be eagerly searched, studied, pored over, by every student among us. From this date forward, the thought of all true Scientists will mount higher, and there will appear correspondingly glorious results in the wide and practical field of demonstration; yet, a full understanding of the book will come only as the ripened fruit of years of study combined with faithful, daily effort to reduce its teachings to practice. Why is a revised edition of SCIENCE AND HEALTH a necessity? Inspiration is not a mechanical process of repeating mere words by rote, of rounding them up in just so many sentences and no more. It is not a lifeless force which can be caught and imprisoned in a word or a volume—as a taxidermist would stuff birds, always to present the same stiff, glassy appearance. It is, rather, the kaleidoscopic presentation of the beauty and wondrous power—not of some new truth heretofore unheard of—but of an eternally existing spiritual Fact unfolding and forever re-unfolding itself to “eyes that see.” . . . Rather, would not each address himself faithfully to the task of clearing up difficulties, of removing doubts as to his precise meaning in certain passages and upon certain points that as yet seem obscure to our sense? The Work is intended for all ages, grades and classes; for the child just beginning to prattle, and for the aged grandsire; for the novitiate just entering upon the study of Christian Science, and for the student who has made, as human language expresses it, the greatest advance. Without wishing to establish any dictum, the writer cannot refrain from giving expression to his conviction that this volume gradually will supersede all teaching, in the technical sense of the word; and further, that it will prove great gain for the Cause of Truth when that day arrives. While, as before stated, this volume is for all grades and classes, it is but pertinent to say that the most conscientious, painstaking and experienced student will advance fastest. There can be no imperative law laid down regarding John’s Gospel, Paul to the Hebrews, or Revelation, to the effect that these are only for advanced Christians to study. Certainly they are for all learners—no hedges are put around them to keep any away; yet, who does not know that the experienced miner will more readily and directly delve to those subterranean depths containing the precious veins of gold! So it will be with the new volume; and we shall very soon come to realize that we have in hand a golden key with which to unlock the Treasure-house of the Bible. The author expresses it as “treasures of Truth first thrown by revelation into her grasp, and now adjusted to be more readily seen.” A practical suggestion or two regarding study of the new edition: In the first place, do not attempt to dispose of the earlier editions. Some are asking, “Can we be permitted to exchange?” Probably not; but you do not want to do so, even if you can. Fortunate is he who has all former revisions, together with the original edition of 1875! They are indicators of successive stages of growth in Christian Science; and as such, at some future day will not only possess historic value, but will be exceedingly difficult to procure. Keep them all; they will prove a “treasure trove.” Again: Let the new volume be studied in connection with earlier editions. The very contrasts help to see how the thoughts have risen only as we have been able to receive them. This, again, will reveal why the new edition could now be written for us. It is simply because the advancing thought, or demonstration, of Christian Students has ascended to that plane which makes it both possible and practicable for us to have the new Work.
