The index appended is brief, and devoted chiefly to Proper Names; the fulness of the Table of Contents seeming to render a longer one unnecessary, which should contain references to subjects. The writer wishes to express his acknowledgments to the chief Librarian of the Bodleian, the Rev. H. O. Coxe, for his kindness in procuring for his use a few foreign works which were necessary. He avails himself also of this opportunity of expressing publicly his thanks to the same individual, for the perseverance with which he has accomplished the scheme of providing a reading-room in connection with the Bodleian Library, open to students in an evening. Those whose time and strength are spent in college or private tuition during the mornings, are thus enabled to avail themselves of the treasures of a library, which until this recent alteration was in a great degree useless to many of the most active minds and diligent students in the university. Thanks are also due to a few other persons for their advice and courtesy in the loan of scarce books; also, in some instances, for assistance in the verification of a reference;(64) and in one case, to a distinguished scholar, for his kindness in revising one of the Notes. The spirit in which the writer has composed the history has been stated elsewhere.(65) His work now goes forth with no extraneous claims on public attention. If it be, by the Divine blessing, the means of affording instruction, guidance, or comfort, to a single mind, the writer’s labour will be amply recompensed. ANALYSIS OF THE LECTURES. Lecture I. _On the subject, method, and purpose of the course of Lectures._ The subject stated to be the struggle of the human mind against the Christian revelation, in whole or in part. (p. 1.) Explanation of the points which form the occasion of the conflict. (pp. 1-3.) The mode of treatment, being that of a critical history, includes (p. 3) the discovery of (1) the facts, (2) the causes, and (3) the moral. The main part of this first lecture is occupied in explaining the second of these divisions. Importance, if the investigation were to be fully conducted, of carrying out a comparative study of religions and of the attitude of the mind in reference to all doctrine that rests on authority. (pp. 4-6.) The idea of causes implies, I. The law of the operation of the causes. II. The enumeration of the causes which act according to this assumed law. The empirical law, or formula descriptive of the action of reason on religion, is explained to be one form of the principle of progress by antagonism, the conservation or discovery of truth by means of inquiry and controversy; a merciful Providence leaving men responsible for their errors, but ultimately overruling evil for good. (p. 7.) This great fact illustrated in the four Crises of the Christian faith in Europe, viz. In the struggle (1) With heathen philosophy, about A.D. 160-360. (p. 8.)
