"to be taken for granted, by many persons, that Christianity is not so much as a subject of inquiry," set himself, in the first instance, to prove "that it is not, however, so clear a case that there is nothing in it;"--this preliminary proof being designed to neutralize objections, and to disburden the subject of all adverse presumptions, so as to be judged on its own proper and independent merits. We are imitating, too, the example of another sagacious writer on a kindred theme, who thought that "Apologists had paid too little attention to the _prejudices_ of their opponents, and had been too confident of accomplishing their object at once, by an overpowering statement of the direct evidence, forgetting that the influence of prejudice renders the human mind very nearly inaccessible to both evidence and argument."[1] If this method was ever necessary or expedient, it is peculiarly so in the present age. Opinions are afloat in society, and are even avowed by men of high philosophical repute, which formally exclude Theology from the domain of human thought, and represent it as utterly inaccessible to the human faculties. They amount to a denial, not merely of its truth, but of its very possibility. They place it among the dreams of the past--with the fables of the Genii, or the follies of Alchemy, or the phantoms of Astrology. They intimate, in no ambiguous terms, not only that Catholicism is effete, and Christianity itself dead or dying, but that Theology of every kind, even the simplest and purest form of Theism, must speedily vanish from the earth. Admitting that the religious element was necessarily developed in the infancy of the species, and that its influence was alike inevitable and salutary during the world's minority, when it was placed provisionally "under tutors and governors," they proclaim that mankind have outgrown the vestments which suited them in earlier times, and that now they must "put away childish things." That such sentiments have been publicly avowed, that they have been proclaimed as the scientific results of speculative thought, and that they have been widely circulated in the vehicles both of philosophic discussion and of popular literature, will be proved by evidence, equally sad and conclusive, in the succeeding chapters; in the meantime we refer to them merely for the purpose of showing that, in so far as their influence prevails, they must necessarily tend, unless they be counteracted by some effective antidote, to generate such a prejudice against the whole scheme of Theology, whether Natural or Revealed, as may be expected, especially in the case of young, inexperienced, and ardent minds, to prevent them from entertaining the subject at all, or examining, with serious and candid interest, any kind or amount of evidence that might be adduced in regard to it. For this reason, we propose to review the various Theories or Systems which may be said to embody and exhibit these prevailing tendencies, to meet our
