In India and Tibet, again, Brahmanism and Buddhism may be said to have divided these three elements between them, the former representing as great an excess of the external as Buddhism does of abstruse reasoning and pessimistic emotion. Mahometanism, while combining, in very imperfect proportions, all three elements within itself, lays special stress upon the first, the external element; and though harbouring, for centuries now and more or less everywhere, the third, the mystical element, looks, in its strictly orthodox representatives, with suspicion upon this mysticism. Judaism was slow in developing the second, the intellectual element; and the third, the mystical, is all but wholly absent till the Exilic period, and does not become a marked feature till still later on, and in writers under Hellenistic influence. It is in the Book of Wisdom, still more in Philo, that we find all three sides almost equally developed. And from the Hasmonean period onwards till the destruction of Jerusalem by Titus, we find a severe and ardent external, traditional, authoritative school in the Pharisees; an accommodating and rationalizing school in the Sadducees; and, apart from both, more a sect than a school, the experimental, ascetical, and mystical body of the Essenes. But it is in Christianity, and throughout its various vicissitudes and schools, that we can most fully observe the presence, characteristics, and interaction of these three modalities. We have already seen how the New Testament writings can be grouped, with little or no violence, according to the predominance of one of these three moods, under the heads of the traditional, historic, external, the “Petrine” school; the reasoning, speculative-internal, the Pauline; and the experimental, mystical-internal, the Joannine school. And in the East, up to Clement of Alexandria, in the West up to St. Augustine, we find the prevalence of the first type. And next, in the East, in Clement and Origen, in St. Gregory of Nyssa, in the Alexandrian and the Antiochene school generally, and in the West, in St. Augustine, we find predominantly a combination of the second and third types. The Areopagitic writings of the end of the fifth century still further emphasize and systematize this Neo-Platonic form of mystical speculation, and become indeed the great treasure-house from which above all the Mystics, but also largely the Scholastics, throughout the Middle Ages, drew much of their literary material.
