In the popular sense of the word, enthusiasm means a high state of mental excitement. In that state all the powers are exalted, the thoughts become more comprehensive and vivid, the feelings more fervid, and the will more determined. It is in these periods of excitement that the greatest works of genius, whether by poets, painters, or warriors, have been accomplished. The ancients referred this exaltation of the inner man to a divine influence. They regarded persons thus excited as possessed, or having a God within them. Hence they were called enthusiasts (ἔνθεος). In theology, therefore, those who ignore or reject the guidance of the Scriptures, and assume to be led by an inward divine influence into the knowledge and obedience of the truth, are properly called Enthusiasts. This term, however, has been in a great measure superseded by the word Mystics.
Few words indeed have been used in such a vague, indefinite sense as Mysticism. Its etymology does not determine its meaning. A μύστης was one initiated into the knowledge of the Greek mysteries, one to whom secret things had been revealed. Hence in the wide sense of the word, a Mystic is one who claims to see or know what is hidden from other men, whether this knowledge be attained by immediate intuition, or by inward revelation. In most cases these methods were assumed to be identical, as intuition was held to be the immediate vision of God and of divine things. Hence, in the wide sense of the word, Mystics are those who claim to be under the immediate guidance of God or of his Spirit.
A. The Philosophical Use of the Word.
Hence Mysticism, in this sense, includes all those systems of philosophy, which teach either the identity of God and the soul, or the immediate intuition of the infinite. The pantheism of the Brahmins and Buddhists, the theosophy of the Sufis, the Egyptian, and many forms of the Greek philosophy, in this acceptation of the
term, are all Mystical. As the same system has been reproduced in modern times, the same designation is applied to the philosophy of Spinoza, and its various modifications. According to Cousin, “Mysticism in philosophy is the belief that God may be known face to face, without anything intermediate. It is a yielding to the sentiment awakened by the idea of the infinite, and a running up of all knowledge and all duty to the contemplation and love of Him.”1
For the same reason the whole Alexandrian school of theology in the early Church has been called Mystical. They characteristically depreciated the outward authority of the Scriptures, and exalted that of the inward light. It is true they called that light reason, but they regarded it as divine. According to the new Platonic doctrine, the Λόγος, or impersonal reason of God, is Reason in man; or as Clemens Alexandrinus said, The Logos was a light common to all men. That, therefore, to which supreme authority was ascribed in the pursuit of truth, was “God within us.” This is the doctrine of modern Eclecticism as presented by Cousin. That philosopher says, “Reason is impersonal in its nature. It is not we who make it. It is so far from being individual, that its peculiar characteristics are the opposite of individuality, namely, universality and necessity, since it is to Reason we owe the knowledge of universal and necessary truths, of principles which we all obey, and cannot but obey… . . It descends from God, and approaches man. It makes its appearance in the consciousness as a guest, who brings intelligence of an unknown world, of which it at once presents the idea and awakens the want. If reason were personal, it would have no value, no authority beyond the limits of the individual subject… . . Reason is a revelation, a necessary and universal revelation which is wanting to no man, and which enlightens every man on his coming into the world. Reason is the necessary mediator between God and man, the Λόγος of Pythagoras and Plato, the Word made Flesh, which serves as the interpreter of God, and teacher of man, divine and human at the same time. It is not indeed the absolute God in his majestic individuality, but his manifestation in spirit and in truth. It is not the Being of beings, but it is the revealed God of the human race.”2
Reason, according to this system, is not a faculty of the human
soul, but God in man. As electricity and magnetism are (or used to be) regarded as forces diffused through the material world, so the Λόγος, the divine impersonal reason, is diffused through the world of mind, and reveals itself more or less potentially in the souls of all men. This theory, in one aspect, is a form of Rationalism, as it refers all our higher, and especially our religious knowledge, to a subjective source, which it designates Reason. It has, however, more points of analogy with Mysticism, because, (1.) It assumes that the informing principle, the source of knowledge and guide in duty, is divine, something which does not belong to our nature, but appears as a guest in our consciousness. (2.) The office of this inward principle, or light, is the same in both systems. It is to reveal truth and duty, to elevate and purify the soul. (3.) Its authority is the same; that is, it is paramount if not exclusive. (4.) Its very designations are the same. It is called by philosophers, God, the Λόγος, the Word; by Christians, Christ within us, or, the Spirit. Thus systems apparently the most diverse (Cousin and George Fox!) run into each other, and reveal themselves as reproductions of heathen philosophy, or of the heresies of the early Church.
