apperception with will, and regards it as the unitary principle. Külpe and Titchener find no self, or will, or soul, but treat these as inferences little warranted. Their psychology is psychology without a soul. The old psychology was exclusively _static_, while the new emphasizes the genetic point of view. Growth and development are the leading ideas of Herbert Spencer, Preyer, Tracy and Stanley Hall. William James is explanatory, while George T. Ladd is descriptive. Cattell, Scripture, and Münsterberg apply the methods of Fechner, and the Psychological Review is their organ. Their error is in their negative attitude. The old psychology is needed to supplement the new. It has greater scope and more practical significance.” On the relation of theology to philosophy and to science, see Luthardt, Compend. der Dogmatik, 4; Hagenbach, Encyclopädie, 109. III. History of Systematic Theology. 1. _In the Eastern Church_, Systematic Theology may be said to have had its beginning and end in John of Damascus (700-760). Ignatius († 115—Ad Trall., c. 9) gives us “the first distinct statement of the faith drawn up in a series of propositions. This systematizing formed the basis of all later efforts” (Prof. A. H. Newman). Origen of Alexandria (186-254) wrote his Περὶ Ἀρχῶν; Athanasius of Alexandria (300-373) his Treatises on the Trinity and the Deity of Christ; and Gregory of Nyssa in Cappadocia (332-398) his Λόγος κατηχητικὸς ὁ μέγας. Hatch, Hibbert Lectures, 323, regards the “De Principiis” of Origen as the “first complete system of dogma,” and speaks of Origen as “the disciple of Clement of Alexandria, the first great teacher of philosophical Christianity.” But while the Fathers just mentioned seem to have conceived the plan of expounding the doctrines in order and of showing their relation to one another, it was John of Damascus (700-760) who first actually carried out such a plan. His Ἔκδοσις ἀκριβὴς τῆς ὀρθοδόξου Πίστεως, or Summary of the Orthodox Faith, may be considered the earliest work of Systematic Theology. Neander calls it “the most important doctrinal text-book of the Greek Church.” John, like the Greek Church in general, was speculative, theological, semi-pelagian, sacramentarian. The Apostles’ Creed, so called, is, in its present form, not earlier than the fifth century; see Schaff, Creeds of Christendom, 1:19. Mr. Gladstone suggested that the Apostles’ Creed was a development of the baptismal formula. McGiffert, Apostles’ Creed, assigns to the meagre original form a date of the third quarter of the second century, and regards the Roman origin of the symbol as proved. It was framed as a baptismal formula, but specifically in opposition to the teachings of Marcion, which were at that time causing much trouble at Rome. Harnack however dates the original Apostles’
