Some of these fables are quite obviously due to a materialisation of conventional symbols. These symbols are the picture language into which the imagination translates what the soul has felt. A typical case is that of the miniature image of Christ, which is said to have been found embedded in the heart of a deceased saint. The supposed miracle was, of course, the work of imagination; but this does not mean that those who reported it were deliberate liars. We know now that we must distinguish between observation and imagination, between the language of science and that of poetical metaphor; but in an age which abhorred rationalism this was not so clear[337]. Rationalism has its function in proving that such mystical symbols are not physical facts. But when it goes on to say that they are related to physical facts as morbid hallucinations to realities, it has stepped outside its province.

Proceeding a little further as we trace the development of natural or objective religion, we come to the belief in magic, which in primitive peoples is closely associated with their first attempts at experimental science. What gives magic its peculiar character is that it is based on fanciful, and not on real correspondences. The uneducated mind cannot distinguish between associations of ideas which are purely arbitrary and subjective, and those which have a more universal validity. Not, of course, that all the affinities seized upon by primitive man proved illusory; but those which were not so ceased to be magical, and became scientific. The savage draws no distinction between the process by which he makes fire and that by which his priest calls down rain, except that the latter is a professional secret; drugs and spells are used indifferently to cure the sick; astronomy and astrology are parts of the same science. There is, however, a difference between the magic which is purely naturalistic and that which makes mystical claims. The magician sometimes claims that the spirits are subject to him, not because he has learned how to wield the forces which they must obey, but because he has so purged his higher faculties that the occult sympathies of nature have become apparent to him. His theosophy claims to be a spiritual illumination, not a scientific discovery. The error here is the application of spiritual clairvoyance to physical relations. The insight into reality, which is unquestionably the reward of the pure heart and the single eye, does not reveal to us in detail how nature should be subdued to our needs. No spirits from the vasty deep will obey our call, to show us where lies the road to fortune or to ruin. Physical science is an abstract inquiry, which, while it keeps to its proper subject—the investigation of the relations which prevail in the phenomenal world—is self-sufficient, and can receive nothing on external authority. Still less can the adept usurp Divine powers, and bend the eternal laws of the universe to his puny will.

The turbid streams of theurgy and magic flowed into the broad river of Christian thought by two channels—the later Neoplatonism, and Jewish Cabbalism. Of the former something has been said already. The root-idea of the system was that all life may be arranged in a descending scale of potencies, forming a kind of chain from heaven to earth. Man, as a microcosm, is in contact with every link in the chain, and can establish relations with all spiritual powers, from the superessential One to the lower spirits or "dæmons." The philosopher-saint, who had explored the highest regions of the intelligence, might hope to dominate the spirits of the air, and compel them to do his bidding. Thus the door was thrown wide open for every kind of superstition. The Cabbalists followed much the same path. The word Cabbala means "oral tradition," and is defined by Reuchlin as "the symbolic reception of a Divine revelation handed down for the saving contemplation of God and separate forms.[338]" In another place he says, "The Cabbala is nothing else than symbolic theology, in which not only are letters and words symbols of things, but things are symbols of other things." This method of symbolic interpretation was held to have been originally communicated by revelation,[339] in order that persons of holy life might by it attain to a mystical communion with God, or deification. The Cabbalists thus held much the same relation to the Talmudists as the mystics to the scholastics in the twelfth century. But, as Jews, they remained faithful to the two doctrines of an inspired tradition and an inspired book, which distinguish them from Platonic mystics.[340]

Pico de Mirandola (born 1463) was the first to bring the Cabbala into Christian philosophy, and to unite it with his Neoplatonism. Very characteristic of his age is the declaration that "there is no natural science which makes us so certain of the Divinity of Christ as Magic and the Cabbala.[341]" For there was at that period a curious alliance of Mysticism and natural science against scholasticism, which had kept both in galling chains; and both mystics and physicists invoked the aid of Jewish theosophy. Just as Pythagoras, Plato, and Proclus were set up against Aristotle, so the occult philosophy of the Jews, which on its speculative side was mere Neoplatonism, was set up against the divinity of the Schoolmen. In Germany, Reuchlin (1455-1522) wrote a treatise, On the Cabbalistic Art, in which a theological scheme resembling those of the Neoplatonists and speculative mystics was based on occult revelation. The book captivated Pope Leo X. and the early Reformers alike.

The influence of Cabbalism at this period was felt not only in the growth of magic, but in the revival of the science of allegorism, which resembles magic in its doctrine of occult sympathies, though without the theurgic element. According to this view of nature, everything in the visible world has an emblematic meaning. Everything that a man saw, heard, or did—colours, numbers, birds, beasts, and flowers, the various actions of life—was to remind him of something else.[342] The world was supposed to be full of sacred cryptograms, and every part of the natural order testified in hieroglyphics[343] to the truths of Christianity. Thus the shamrock bears witness to the Trinity, the spider is an emblem of the devil, and so forth. This kind of symbolism was and is extensively used merely as a picture-language, in which there is no pretence that the signs are other than artificial or conventional. The language of signs may be used either to instruct those who cannot understand words, or to baffle those who can. Thus, a crucifix may be as good as a sermon to an illiterate peasant; while the sign of a fish was used by the early Christians because it was unintelligible to their enemies. This is not symbolism in the sense which I have given to the word in this Lecture.[344] But it is otherwise when the type is used as a proof of the antitype. This latter method had long been in use in biblical exegesis. Pious persons found a curious satisfaction in turning the most matter of fact statements into enigmatic prophecies. Every verse must have its "mystical" as well as its natural meaning, and the search for "types" was a recognised branch of apologetics. Allegorism became authoritative and dogmatic, which it has no right to be. It would be rash to say that this pseudo-science, which has proved so attractive to many minds, is entirely valueless. The very absurdity of the arguments used by its votaries should make us suspect that there is a dumb logic of a more respectable sort behind them. There is, underlying this love of types and emblems, a strong conviction that if "one eternal purpose runs" through the ages, it must be discernible in small things as well as in great. Everything in the world, if we could see things as they are, must be symbolic of the Divine Power which made it and maintains it in being. We cannot believe that anything in life is meaningless, or has no significance beyond the fleeting moment. Whatever method helps us to realise this is useful, and in a sense true. So far as this we may go with the allegorists, while at the same time we may be thankful that the cobwebs which they spun over the sacred texts have now been cleared away, so that we can at last read our Bible as its authors intended it to be read.[345]

Theosophical and magical Mysticism culminated in the sixteenth and seventeenth centuries. Just as the idealism of Plotinus lost itself in the theurgic system of Iamblichus, so the doctrine of Divine immanence preached by Eckhart and his school was followed by the Nature-Mysticism of Cornelius Agrippa[346] and Paracelsus.[347] The "negative road" had been discredited by Luther's invective, and Mysticism, instead of shutting her eyes to the world of phenomena, stretched forth her hands to conquer and annex it. The old theory of a World-Spirit, the pulsations of whose heart are felt in all the life of the universe, came once more into favour. Through all phenomena, it was believed, runs an intricate network of sympathies and antipathies, the threads of which, could they be disentangled, would furnish us with a clue through all the labyrinths of natural and supernatural science. The age was impatient to enter on the inheritance from which humanity had long been debarred; the methods of experimental science seemed tame and slow; and so we find, especially in Germany, an extraordinary outburst of Nature-Mysticism— astrology, white magic, alchemy, necromancy, and what not—such as Christianity had not witnessed before. These pseudo-sciences (with which was mingled much real progress in medicine, natural history, and kindred sciences) were divided under three provinces or "vincula"—those of the Spiritual World, which were mainly magical invocations, diagrams, and signs; those of the Celestial World, which were taught by astrology; and those of the Elemental World, which consisted in the sympathetic influence of material objects upon each other. These secrets (it was held) are all discoverable by man; for man is a microcosm, or epitome of the universe, and there is nothing in it with which he cannot claim an affinity. In knowing himself, he knows both God and all the other works that God has made.

The subject of Nature-Mysticism is a fascinating one; but I must here confine myself to its religious aspects. An attempt was soon made, by Valentine Weigel (1533-1588), Lutheran pastor at Tschopau, to bring together the new objective Mysticism—freed from its superstitious elements—and the traditional subjective Mysticism which the Middle Ages had handed down from Dionysius and the Neoplatonists. Weigel's cosmology is based on that of Paracelsus; and his psychology also reminds us of him. Man is a microcosm, and his nature has three parts—the outward material body, the astral spirit, and the immortal soul, which bears the image of God. The three faculties of the soul correspond to these three parts; they are sense, reason (Vernunft), and understanding (Verstand). These are the "three eyes" by which we get knowledge. The sense perceives material things; the reason, natural science and art; the understanding, which he also calls the spark, sees the invisible and Divine. He follows the scholastic mystics in distinguishing between natural and supernatural knowledge, but his method of distinguishing them is, I think, original. Natural knowledge, he says, is not conveyed by the object; it is the percipient subject which creates knowledge out of itself. The object merely provokes the consciousness into activity. In natural knowledge the subject is "active, not passive"; all that appears to come from without is really evolved from within. In supernatural knowledge the opposite is the case. The eye of the "understanding," which sees the Divine, is the spark in the centre of the soul where lies the Divine image. In this kind of cognition the subject must be absolutely passive; its thoughts must be as still as if it were dead. Just as in natural knowledge the object does not co-operate, so in supernatural knowledge the subject does not co-operate. Yet this supernatural knowledge does not come from without. The Spirit and Word of God are within us. God is Himself the eye and the light in the soul, as well as the object which the eye sees by this light. Supernatural knowledge flows from within outwards, and in this way resembles natural knowledge. But since God is both the eye that sees and the object which it sees, it is not we who know God, so much as God who knows Himself in us. Our inner man is a mere instrument of God.

Thus Weigel, who begins with Paracelsus, leaves off somewhere near Eckhart—and Eckhart in his boldest mood. But his chief concern is to attack the Bibliolaters (Buchstabentheologen) in the Lutheran Church, and to protest against the unethical dogma of imputed righteousness. We need not follow him into either of these controversies, which give a kind of accidental colouring to his theology. Speculative Mysticism, which is always the foe of formalism and dryness in religion, attacks them in whatever forms it finds them; and so, when we try to penetrate the essence of Mysticism by investigating its historical manifestations, we must always consider what was the system which in each case it was trying to purify and spiritualise. Weigel's Mysticism moves in the atmosphere of Lutheran dogmatics. But it also marks a stage in the general development of Christian Mysticism, by giving a positive value to scientific and natural knowledge as part of the self-evolution of the human soul. "Study nature," he says, "physics, alchemy, magic, etc.; for it is all in you, and you become what you have learnt." It is true that his religious attitude is rigidly quietistic; but this position is so inconsistent with the activity which he enjoins on the "reason," that he may claim the credit of having exhibited the contradiction between the positive and negative methods in a clear light; and to prove a contradiction is always the first step towards solving it.

A more notable effort in the same direction was that of Jacob Böhme, who, though he had studied Weigel, brought to his task a philosophical genius which was all his own.

Böhme was born in 1575 near Görlitz, where he afterwards settled as a shoemaker and glover. He began to write in 1612, and in spite of clerical opposition, which silenced him for five years, he produced a number of treatises between that date and his death in 1624.
