High above all other names in his Pantheon of Nihilism, Mr. Huxley writes that of David Hume. He esteems that philosopher’s great service to humanity to be his irrefragable demonstration of “the limits of philosophical inquiry,” outside which lie the fundamental doctrines “of spiritualism,” and other “isms.” It is true that the tenth chapter of Hume’s Enquiry Concerning Human Understanding was so highly esteemed by its author, that he considered that “with the wise and learned” it would be an “everlasting check to all kinds of superstitious delusion,” which with him was simply a convertible term to represent a belief in some phenomena previously unfamiliar and by him arbitrarily classified as miracle. But, as Mr. Wallace justly observes, Hume’s apothegm, that “a miracle is a violation of the laws of nature,” is imperfect; for in the first place it assumes that we know all the laws of nature; and, second, that an unusual phenomenon is a miracle. Mr. Wallace proposes that a miracle should be defined as: “any act or event necessarily implying the existence and agency of superhuman intelligences.” Now Hume himself says that “a uniform experience amounts to a proof,” and Huxley, in this famous essay of his, admits that all we can know of the existence of the law of gravitation is that since, in all human experience, stones unsupported have fallen to the ground, there is no reason for believing that the same thing will not occur again, under the same circumstances, but, on the contrary, every reason to believe that it will.

If it were certain that the limits of human experience could never be enlarged, then there might be some justice in Hume’s assumption that he was familiar with all that could happen under natural law, and some decent excuse for the contemptuous tone which marks all of Huxley’s allusions to spiritualism. But, as it is evident from the writings of both these philosophers, that they are ignorant of the possibilities of psychological phenomena, too much caution cannot be used in according weight to their dogmatic assertions. One would really suppose that a person who should permit himself such rudeness of criticism upon spiritualistic manifestations had qualified himself for the office of censor by an adequate course of study; but, in a letter addressed to the London Dialectical Society, Mr. Huxley, after saying that he had no time to devote to the subject, and that it does not interest him, makes the following confession, which shows us upon what slight foundation modern scientists sometimes form very positive opinions. “The only case of spiritualism,” he writes, “I ever had the opportunity of examining into for myself, was as gross an imposture as ever came under my notice.”

What would this protoplasmic philosopher think of a spiritualist who, having had but one opportunity to look through a telescope, and upon that sole occasion had had some deception played upon him by a tricky assistant at the observatory, should forthwith denounce astronomy as a “degrading belief?” This fact shows that scientists, as a rule, are useful only as collectors of physical facts; their generalizations from them are often feebler and far more illogical than those of their lay critics. And this also is why they misrepresent ancient doctrines.

Professor Balfour Stewart pays a very high tribute to the philosophical intuition of Herakleitus, the Ephesian, who lived five centuries before our era: the “crying” philosopher who declared that “fire was the great cause, and that all things were in a perpetual flux.” “It seems clear,” says the professor, “that Herakleitus must have had a vivid conception of the innate restlessness and energy of the universe, a conception allied in character to, and only less precise than that of modern philosophers who regard matter as essentially dynamical.” He considers the expression fire as very vague; and quite naturally, for the evidence is wanting to show that either Prof. Balfour Stewart (who seems less inclined to materialism than some of his colleagues) or any of his contemporaries understand in what sense the word fire was used.

His opinions about the origin of things were the same as those of Hippocrates. Both entertained the same views of a supreme power,[665] and, therefore, if their notions of primordial fire, regarded as a material force, in short, as one akin to Leibnitz’s dynamism, were “less precise” than those of modern philosophers, a question which remains to be settled yet, on the other hand their metaphysical views of it were far more philosophical and rational than the one-sided theories of our present-day scholars. Their ideas of fire were precisely those of the later “fire-philosophers,” the Rosicrucians, and the earlier Zoroastrians. They affirmed that the world was created of fire, the divine spirit of which was an omnipotent and omniscient GOD. Science has condescended to corroborate their claims as to the physical question.

Fire, in the ancient philosophy of all times and countries, including our own, has been regarded as a triple principle. As water comprises a visible fluid with invisible gases lurking within, and, behind all the spiritual principle of nature, which gives them their dynamic energy, so, in fire, they recognized: 1st. Visible flame; 2d. Invisible, or astral fire—invisible when inert, but when active producing heat, light, chemical force, and electricity, the molecular powers; 3d. Spirit. They applied the same rule to each of the elements; and everything evolved from their combinations and correlations, man included, was held by them to be triune. Fire, in the opinion of the Rosicrucians, who were but the successors of the theurgists, was the source, not only of the material atoms, but also of the forces which energize them. When a visible flame is extinguished it has disappeared, not only from the sight but also from the conception of the materialist, forever. But the Hermetic philosopher follows it through the “partition-world of the knowable, across and out on the other side into the unknowable,” as he traces the disembodied human spirit, “vital spark of heavenly flame,” into the Æthereum, beyond the grave.[666]

This point is too important to be passed by without a few words of comment. The attitude of physical science toward the spiritual half of the cosmos is perfectly exemplified in her gross conception of fire. In this, as in every other branch of science, their philosophy does not contain one sound plank: every one is honeycombed and weak. The works of their own authorities teeming with humiliating confessions, give us the right to say that the floor upon which they stand is so unstable, that at any moment some new discovery, by one of their own number, may knock away the props and let them all fall in a heap together. They are so anxious to drive spirit out of their conceptions that, as Balfour Stewart says: “There is a tendency to rush into the opposite extreme, and to work physical conceptions to an excess.” He utters a timely warning in adding: “Let us be cautious that, in avoiding Scylla, we do not rush into Charybdis. For the universe has more than one point of view, and there are possibly regions which will not yield their treasures to the most determined physicists, armed only with kilogrammes and meters and standard clocks.”[667] In another place he confesses: “We know nothing, or next to nothing, of the ultimate structure and properties of matter, whether organic or inorganic.”

As to the other great question—we find in Macaulay, a still more unreserved declaration: “The question what becomes of man after death—we do not see that a highly educated European, left to his unassisted reason, is more likely to be in the right than a Blackfoot Indian. Not a single one of the many sciences in which we surpass the Blackfoot Indians throws the smallest light on the state of the soul after the animal life is extinct. In truth, all the philosophers, ancient and modern, who have attempted, without the help of revelation, to prove the immortality of man, from Plato down to Franklin, appear to us to have failed deplorably.”

There are revelations of the spiritual senses of man which may be trusted far more than all the sophistries of materialism. What was a demonstration and a success in the eyes of Plato and his disciples is now considered the overflow of a spurious philosophy and a failure. The scientific methods are reversed. The testimony of the men of old, who were nearer to truth, for they were nearer to the spirit of nature—the only aspect under which the Deity will allow itself to be viewed and understood—and their demonstrations, are rejected. Their speculations—if we must believe the modern thinkers—are but the expression of a redundance of the unsystematic opinions of men unacquainted with the scientific method of the present century. They foolishly based the little they knew of physiology on well-demonstrated psychology, while the scholar of our day bases psychology—of which he confesses himself utterly ignorant—on physiology, which to him is as yet a closed book, and has not even a method of its own, as Fournié tells us. As to the last objection in Macaulay’s argument, it was answered by Hippocrates centuries ago: “All knowledge, all arts are to be found in nature,” he says; “if we question her properly she will reveal to us the truths to pertain to each of these and to ourselves. What is nature in operation but the very divinity itself manifesting its presence? How are we to interrogate her; and how is she to answer us? We must proceed with faith, with the firm assurance of discovering at last the whole of the truth; and nature will let us know her answer, through our inner sense, which with the help of our knowledge of a certain art or science, reveals to us the truth so clearly that further doubt becomes impossible.”[668]

Thus, in the case in hand, the instinct of Macaulay’s Blackfoot Indian is more to be trusted than the most instructed and developed reason, as regards man’s inner sense which assures him of his immortality. Instinct is the universal endowment of nature by the Spirit of the Deity itself; reason the slow development of our physical constitution, an evolution of our adult material brain. Instinct, as a divine spark, lurks in the unconscious nerve-centre of the ascidian mollusk, and manifests itself at the first stage of action of its nervous system as what the physiologist terms the reflex action. It exists in the lowest classes of the acephalous animals as well as in those that have distinct heads; it grows and develops according to the law of the double evolution, physically and spiritually; and entering upon its conscious stage of development and progress in the cephalous species already endowed with a sensorium and symmetrically-arranged ganglia, this reflex action, whether men of science term it automatic, as in the lowest species, or instinctive, as in the more complex organisms which act under the guidance of the sensorium and the stimulus originating in distinct sensation, is still one and the same thing. It is the divine instinct in its ceaseless progress of development. This instinct of the animals, which act from the moment of their birth each in the confines prescribed to them by nature, and which know how, save in accident proceeding from a higher instinct than their own, to take care of themselves unerringly—this instinct may, for the sake of exact definition, be termed automatic; but it must have either within the animal which possesses it or without, something’s or some one’s intelligence to guide it.
