In thus realising the undifferentiated unity of Living Spirit as the central fact of any system, whether the system of the entire universe or of a single organism, we are therefore following a strictly scientific method. We pursue our analysis until it necessarily leads us to this final fact, and then we accept this fact as the basis of our synthesis. The Science of Spirit is thus not one whit less scientific than the Science of Matter; and, moreover, it starts from the same initial fact, the fact of a living energy which defies definition or explanation, wherever we find it; but it differs from the science of matter in that it contemplates this energy under an aspect of responsive intelligence which does not fall within the scope of physical science, as such. The Science of Spirit and the Science of Matter are not opposed. They are complementaries, and neither is fully comprehensible without some knowledge of the other; and, being really but two portions of one whole, they insensibly shade off into each other in a border-land where no arbitrary line can be drawn between them. Science studied in a truly scientific spirit, following out its own deductions unflinchingly to their legitimate conclusions, will always reveal the twofold aspect of things, the inner and the outer; and it is only a truncated and maimed science that refuses to recognise both.
The study of the material world is not Materialism, if it be allowed to progress to its legitimate issue. Materialism is that limited view of the universe which will not admit the existence of anything but mechanical effects of mechanical causes, and a system which recognises no higher power than the physical forces of nature must logically result in having no higher ultimate appeal than to physical force or to fraud as its alternative. I speak, of course, of the tendency of the system, not of the morality of individuals, who are often very far in advance of the systems they profess. But as we would avoid the propagation of a mode of thought whose effects history shows only too plainly, whether in the Italy of the Borgias, or the France of the First Revolution, or the Commune of the Franco-Prussian War, we should set ourselves to study that inner and spiritual aspect of things which is the basis of a system whose logical results are truth and love instead of perfidy and violence.
Some of us, doubtless, have often wondered why the Heavenly Jerusalem is described in the Book of Revelations as a cube; "the length and the breadth and the height of it are equal." This is because the cube is the figure of perfect stability, and thus represents Truth, which can never be overthrown. Turn it on what side you will, it still remains the perfect cube, always standing upright; you cannot upset it. This figure, then, represents the manifestation in concrete solidity of that central life-giving energy, which is not itself any one plane but generates all planes, the planes of the above and of the below and of all four sides. But it is at the same time a city, a place of habitation; and this is because that which is "the within" is Living Spirit, which has its dwelling there.
As one plane of the cube implies all the other planes and also "the within," so any plane of manifestation implies the others and also that "within" which generates them all. Now, if we would make any progress in the spiritual side of science—and every department of science has its spiritual side—we must always keep our minds fixed upon this "innermost within" which contains the potential of all outward manifestation, the "fourth dimension" which generates the cube; and our common forms of speech show how intuitively we do this. We speak of the spirit in which an act is done, of entering into the spirit of a game, of the spirit of the time, and so on. Everywhere our intuition points out the spirit as the true essence of things; and it is only when we commence arguing about them from without, instead of from within, that our true perception of their nature is lost.
The scientific study of spirit consists in following up intelligently and according to definite method the same principle that now only flashes upon us at intervals fitfully and vaguely. When we once realise that this universal and unlimited power of spirit is at the root of all things and of ourselves also, then we have obtained the key to the whole position; and, however far we may carry our studies in spiritual science, we shall nowhere find anything else but particular developments of this one universal principle. "The Kingdom of Heaven is within you."

I have laid stress on the fact that the "innermost within" of all things is living Spirit, and that the Science of Spirit is distinguished from the Science of Matter in that it contemplates Energy under an aspect of responsive intelligence which does not fall within the scope of physical science, as such. These are the two great points to lay hold of if we would retain a clear idea of Spiritual Science, and not be misled by arguments drawn from the physical side of Science only—the livingness of the originating principle which is at the heart of all things, and its intelligent and responsive nature. Its livingness is patent to our observation, at any rate from the point where we recognise it in the vegetable kingdom; but its intelligence and responsiveness are not, perhaps, at once so obvious. Nevertheless, a little thought will soon lead us to recognise this also.
No one can deny that there is an intelligent order throughout all nature, for it requires the highest intelligence of our most highly-trained minds to follow the steps of this universal intelligence which is always in advance of them. The more deeply we investigate the world we live in, the more clear it must become to us that all our science is the translation into words or numerical symbols of that order which already exists. If the clear statement of this existing order is the highest that the human intellect can reach, this surely argues a corresponding intelligence in the power which gives rise to this great sequence of order and interrelation, so as to constitute one harmonious whole. Now, unless we fall back on the idea of a workman working upon material external to himself—in which case we have to explain the phenomenon of the workman—the only conception we can form of this power is that it is the Living Spirit inherent in the heart of every atom, giving it outward form and definition, and becoming in it those intrinsic polarities which constitute its characteristic nature.
There is no random work here. Every attraction and repulsion acts with its proper force collecting the atoms into molecules, the molecules into tissues, the tissues into organs, and the organs into individuals. At each stage of the progress we get the sum of the intelligent forces which operate in the constituent parts, plus a higher degree of intelligence which we may regard as the collective intelligence superior to that of the mere sum-total of the parts, something which belongs to the individual as a whole, and not to the parts as such. These are facts which can be amply proved from physical science; and they also supply a great law in spiritual science, which is that in any collective body the intelligence of the whole is superior to that of the sum of the parts.
Spirit is at the root of all things, and thoughtful observation shows that its operation is guided by unfailing intelligence which adapts means to ends, and harmonises the entire universe of manifested being in those wonderful ways which physical science renders clearer every day; and this intelligence must be in the generating spirit itself, because there is no other source from which it could proceed. On these grounds, therefore, we may distinctly affirm that Spirit is intelligent, and that whatever it does is done by the intelligent adaptation of means to ends.
But Spirit is also responsive. And here we have to fall back upon the law above stated, that the mere sum of the intelligence of Spirit in lower degrees of manifestation is not equal to the intelligence of the complex whole, as a whole. This is a radical law which we cannot impress upon our minds too deeply. The degree of spiritual intelligence is marked by the wholeness of the organism through which it
