meet with as direct negatives as the truth supplies. such sweeping negations. In so doing I have aimed as much as possible to avoid abstruse metaphysics and technical terms for the ordinary reader's sake, but have given to students the opportunity of appreciating the very words of those who in Haeckel's native land strenuously oppose his doctrines. I have also preferred throughout to express my own views in the words of others, whose greater competence will serve to add weight to the statements made. In almost every case I have given the exact words of Professor Haeckel, or of his English advocate. This detail is not superfluous, because it is impossible, in numberless cases, to deal effectively with such assertions as theirs in any other way. Whether such an attempt to maintain Christian truth against modern assault is as unnecessary and 'distressful' a popular preachers not seldom affirm must be left to the reader's intelligence and honesty. It is only too true that many Christian teachers are serenely confident only because they live in a conservatory which excludes all reference to the atmosphere outside. Such a method will avail, doubtless, for the maintenance of an esoteric sect, but cannot either truly or wisely represent the attitude of the Christian Church, which is to aim at moving, let alone winning, the world of humanity. Far indeed as every true Christian may be from panic, it is but the confidence of ignorance which is blind to the seriousness of the modern situation. The imagination that this country-to say nothing of the Continent-can be flooded with half a million of such publications as are here scrutinized, without producing any anti-Christian effect that need be noticed, is but an imitation of the policy of the pursued ostrich, altogether unworthy of those who are bidden on the highest authority to be 'wise as serpents' no less than 'innocent as doves.' That real and lasting good may be brought to pass by 'missions' and 'revivals' is not here disputed. But it is simply childish to suggest that by such means alone all the vexed problems of our day, scientific, philosophical, critical, social, will be for thoughtful people-and especially for the better-educated young men and women in our midst-either solved on Christian principles or robbed of their anti-Christian tendencies. It is surely beyond dispute that in all the departments of modern life intellectual questions are multiplying, and practical problems are thickening. In such a case, all who are attached to the Churches, whatever their degree of culture, are warranted in looking to their avowed teachers for guidance in regard to the quantity and quality of that adaptation to environment which becomes as manifestly necessary for theology as for any other branch of human study. To ignore such a patent need would be but an ecclesiastical renewal of the policy of Rehoboam, alike treasonable to truth and ruinous to religion. The positive grounds of fundamental Christian beliefs, in modern light, I hope to set forth in other volumes. Here the task attempted is but to point out plainly and truthfully the many and great errors which characterize the haughty dicta and confident prophecies of Haeckel's monism. Well knowing the thanklessness of the undertaking, no one regrets its necessity more than the writer. Meanwhile, for all concerned in the 'search for truth,' there can be no better philosophical method than that embodied in the apostolic maxim: 'In malice be ye babes, but in mind be men.'

'You see, Hylas, the water of yonder fountain, how it is forced upwards, in a round column, to a certain height; at which it breaks, and falls back into the basin from which it rose; its ascent as well as descent proceeding from the same uniform law or principle of gravi tation. Just so, the same principles which at first view lead to scepticism, pursued to a certain point, bring men back to common sense.' BISHOP BERKELEY. See Selections from the Literature of |
