According to the fundamental thought just expounded, we find that the physical medium used in all attempts at magic, never was regarded in any other light than in that of a vehicle for a thing metaphysical; otherwise it could evidently stand in no relation whatever to the effect contemplated. These media consisted in cabalistic words, symbolical actions, traced figures, wax images, &c. &c. We see too that, according to the original feeling, what this vehicle conveyed, was in the last resort always an act of volition that had been connected with it. The very natural inducement to do this, was the observation, that every moment men became aware of a completely unaccountable, that is, evidently metaphysical, agency of the will, in the movements of their own bodies. Might not this agency, they thought, be extended to other bodies also? To find out a way to annul the isolation in which the will finds itself in each individual, and to extend the immediate sphere of the will's action beyond the organism of the person willing, was the aim of Magic.

A great deal was nevertheless still wanting ere this fundamental thought, from which Magic seems properly to have sprung, could pass over at once into distinct consciousness and be recognised in abstracto, and ere Magic could at once understand itself. Only a few thoughtful and learned writers of former ages—as I mean soon to prove by quotations—express the distinct thought, that it is in the will itself that the magic power lies, and that the strange signs and acts together with the senseless words that accompanied them, which passed for the means of exorcising and the connecting link with demons, are in fact merely vehicles and means for fixing the will, by which the act of volition, which is to act magically, ceases to be mere wish and becomes deed, or, to use the language of Paracelsus, "receives a corpus," and the individual will in a sense distinctly proclaims that it is now acting as general will, as will in itself. For in every act of Magic—charm-cure or whatever else it may be—the outward action (the connecting link) is exactly what the passes are in magnetising: i.e. not what is really essential, but the mere vehicle, that by which the will, the only real agent, is directed and fixed in the material world and enters into reality. As a rule therefore, it is indispensable.—From the rest of the writers of those times we gather that, in conformity with that fundamental thought of Magic, their only aim was to obtain absolute, arbitrary power over Nature. But they were unable to elevate themselves to the thought that this power must be a direct one; they conceived it, on the contrary, absolutely as an indirect one. For all religions in all countries had placed Nature under the dominion of gods and of demons. Now, it was the magician's endeavour to subject these gods and demons to his will, to induce, nay, to force them to serve him; and he attributed all that he succeeded in achieving to their agency, just as Mesmer attributed the success of his Magnetism to the magnetic rods he held in his hands, instead of to his will which was the real agent. It was in this sense that all polytheistic nations took the matter, and even Plotinus,[305] but more especially Iamblichus, understood Magic: that is, as Theurgy, an expression which Porphyry was the first to use. That divine aristocracy, Pantheism, was favourable to this interpretation, since it distributed the dominion over the different forces of Nature among as many gods and demons—mostly mere personifications of natural forces—and the magician, by persuasion or by force, subjected now one, now the other of these divinities to his power and made them do his bidding. But in a Divine Monarchy, where all Nature obeys a single ruler, the thought of contracting a private alliance with the Almighty, let alone of exercising sovereignty over him, would have been too audacious. Therefore where Judaism, Christianity or Islam prevailed, the omnipotence of the one God stood in the way of this interpretation of Magic: an omnipotence which the magician could not venture to attack. He had no alternative therefore, but to take refuge with the Devil, and with this rebellious spirit—perhaps even direct descendant of Ahriman—to whom some power over Nature was still attributed, he now entered into a compact, by which he ensured to himself his assistance. This was "necromancy" (the 'black art'). Its antithesis, 'white Magic,' was opposed to it by the circumstance that, in it, the magician did not make friends with the Devil, but rather solicited the permission, not to say co-operation, of the Almighty himself, to intercede with the angels; oftener still, he invoked devils by pronouncing the rarer Hebrew names and titles of the One God, such as Adon-Ai, &c. &c., and compelled them to obey him, without promising them anything in return for their services, in a hell-compulsion[306] (Höllenzwang).—But all these mere interpretations and outward trappings of the thing were received so entirely as its essence and as objective processes, that writers like Bodinus, Delrio, Bindsfeldt, &c., whose knowledge of magic was second-hand and not derived from personal experience, all assert the essential characteristic of Magic to be, that it does not act either through forces of Nature or in a natural way, but through the assistance of the Devil. This view was, and long remained, current everywhere, locally modified according to the religions which prevailed in different countries. The laws against sorcery and the trials for witchcraft were based upon it; likewise, wherever the possibility of Magic was contested, the attacks were generally directed against this opinion. An objective view, such as this, was an inevitable consequence of the decided Realism which prevailed throughout ancient and mediæval Europe and which Descartes was the first to disturb. Till then, Man had not learnt to direct the light of speculative thought towards the mysterious depths of his own inner self, but, on the contrary, had sought everything outside himself. Above all the thought of making the will he found within him rule over Nature, was so bold, that people would have been alarmed by it: therefore it was made to rule over fictitious beings, supposed by the prevailing superstition to have command over Nature, in order through them to obtain at least indirect mastery over Nature. Every sort of god or demon moreover, is always a hypostasis, by which believers of all sects and colours bring to their own comprehension the Metaphysical, that which lies behind Nature, that which gives her existence and consistence and consequently rules over her. Thus, when it is said, that Magic acts by the help of demons, the meaning which lies at the bottom of this thought still is, that it is an agency which is not physically, but metaphysically exercised: that it is not a natural, but a supernatural, agency. Now if, in the small amount of fact which speaks in favour of the reality of Magic: that is, in Animal Magnetism and charm-cures, we still do not recognise anything but an immediate action of the will which here manifests its direct power outside, instead of inside, the individual; if moreover, as I am about to show and to substantiate by decisive, unequivocal citations, those who are more deeply initiated into ancient Magic, derive all its effects from the magician's will alone: this is surely strong empirical evidence in support of my doctrine, that the Metaphysical in general, that which alone exists apart from representation, the thing in itself of the universe—is nothing but what is known to us within ourselves as the will.

Now, if the direct power which may occasionally be exercised over Nature by the will, was conceived by those magicians as a merely indirect one, acquired by the help of demons, this still could not prevent its efficiency wherever and whenever it may have taken place. For, precisely because, in things of this kind, the will acts in itself, in its primariness, therefore apart from representation, its efficiency cannot be frustrated by erroneous conceptions of the intellect; on the contrary, the distance here is a wide one between theory and practice: the errors of the former do not stand in the way of the latter, nor does a correct theory qualify for practice. Mesmer, in the beginning, attributed his agency to the magnetic rods he held in his hands and later on explained the wonders of Animal Magnetism by a materialistic theory of a subtle, all-permeating fluid; nevertheless he produced wonderfully powerful effects. I once myself knew the proprietor of an estate, whose peasants were wont by tradition to have their feverish attacks dispelled by a spell of their master's. Now, although he believed he had convinced himself of the impossibility of all such things, yet he continued good-naturedly to comply with their wish as usual, and indeed often succeeded in relieving them. This success he ascribed to his peasants' firm belief, forgetting that a similar faith ought also to bring success to the medical treatment which is so often applied with complete inefficacy to believing patients.

Now, if Theurgy and Demonomagic, as described above, were but the mere interpretation and outward trappings of the thing, the mere husk, at which the majority were content to stop short: there were nevertheless some, who went below the surface and quite recognised that the agent in influences supposed to proceed from magic, was absolutely nothing but the will. We must not however look for such deeper observers as these among the discountenancers and antagonists of Magic, and the majority of the writers on this subject belong precisely to these: they derived their knowledge exclusively from Courts of Justice and from the examination of witnesses, so that they merely describe the outside of the matter; and, if at any time they chanced, through confessions, to gain an insight into the inner processes they took good care not to betray that knowledge, lest, by doing so, they should contribute to diffuse the terrible vice of sorcery. To this class belong Bodinus, Delrio, Bindsfeldt, and others. For information as to the real nature of the thing, we must on the contrary go to philosophers and investigators of Nature, who wrote in those times of prevailing superstition. Now, from what they say, it clearly follows, that the real agent in Magic, just as in Animal Magnetism, is nothing but the will. Here I must quote some passages in support of this assertion.[307] Theophrastus Paracelsus especially disclosed perhaps more concerning the inner nature of Magic than any other writer, and does not even hesitate to give a minute description of the processes used in it.[308]—He says:[309] "To be observed concerning wax images: if I bear malice in my will against anyone, that malice must be carried out by some medium or corpus. Thus it is possible for my spirit to stab or wound another person without help from my body in using a sword, merely by my fervent desire. Therefore it is also possible for me to convey my opponent's spirit into the image by my will and then to deform or paralyze it at pleasure.—You must know, that the influence of the will is a great point in medicine. For if a man hate another and begrudge him anything good, it is possible that if he curse him, that curse may take effect.—This occurs also with animals and more easily than with men; for the spirit of man has far greater power of resistance than that of animals."

And p. 375: "It follows from this, that one image has magic power over another, not by virtue of the characters or anything of that kind impressed on the virgin wax; but the imagination overcomes its own constellation, so as to become a means for fulfilling the will of its heaven, i.e. of its man."

p. 334: "All the imagining of man comes from his heart. The heart is the sun of the microcosm. And all the imagining of man passes from the small sun of the microcosm into the sun of the great Universe, into the heart of the macrocosm. Thus the imaginatio of the microcosm is a seed which becomes material," &c.

p. 364: "It suffices for you to know what rigorous imagination does, which is the beginning of all magical works."

p. 789: "Even my thought therefore is a looking at a mark. Now I must not turn my eye with my hands in this or that direction; but my imagination turns it as I wish. And this is also to be understood of walking: I desire, I propose to myself, therefore my body moves, and the firmer my thoughts, the more sure it is that I shall run. Thus imaginatio alone is an impulse for my running."

p. 837: "Imaginatio used against me may be employed with such rigour, that I may be killed by the imaginatio of another person."

Vol. ii. p. 274: "Imagination comes from longing and desire: envy, hatred, proceed from longing, for they do not arise unless you long for them. As soon as you wish, the act of the imagination follows. This longing must be quick, ardent, lively, as that of a pregnant woman, &c. &c.—A general curse is commonly verified. Why? It comes from the heart, and the seed lies and is born in that coming from the heart. Thus parents' curses also come from the heart. The curse of the poor is likewise imaginatio. The prisoner's curse, also mere imaginatio, comes from the heart.... Thus too, when one man wishes to stab or paralyze, &c., another by means of his imaginatio, he must first attract the thing and instrument to himself and then he can impress it (with his wish): for whatever enters into it, may also go out of it again by the medium of thought as well as by that of the hands.... In such imagining, women outdo men ... for they are more ardent in revenge."
