(From the Preface) The writer of this work proposes to present in three volumes, in English, an outline of a three year course of Dogmatic Theology, such as is offered to students for the priesthood in Catholic Seminaries. No attempt is made to give more than the merest outline; but it is hoped that it will satisfy the needs of some who are not professional students, especially by showing the nature of the questions dealt with in each Treatise, and their proportionate importance, as indicated by the space allowed to them. Originality would be out of place in a work of this the matter is the common property of theologians. The admirable Compendium of Father Hurter is followed in the arrangement of the Treatises. The aim of the work is Exposition, not Controversy, although controversial matter is occasionally introduced by way of illustration. The writer believes that if both parties to a controversy will give a clear exposition of what they hold upon the subject, the questions between them will quickly be brought to a decision. In the Appendix to this volume will be found a sketch of the method of disputation commonly followed in schools of philosophy and theology, by which the class are practised in the art of stating objections clearly and answering them concisely.
