intellectual life, and it must not be passed by heedlessly by any one concerned with the spiritual interests of humanity. But it is none the less true that the way in which it sets about satisfying spiritual needs is superficial and shallow. If this were the right way, the outlook would indeed be dreary. Would it not be depressing to be obliged to agree with those who say: "Thought is a form of force. We walk by means of the same force by which we think. Man is an organism which transforms various forms of force into thought-force, an organism the activity of which we maintain by what we call 'food,' and with which we produce what we call 'thought.' What a marvellous chemical process it is which could change a certain quantity of food into the divine tragedy of Hamlet." This is quoted from a pamphlet of Robert G. Ingersoll, bearing the title, Modern Twilight of the Gods. It matters little if such thoughts find but scanty acceptance in the outside world. The point is that innumerable people find themselves compelled by the system of natural science to take up with regard to world-processes an attitude in conformity with the above, even when they think they are not doing so.

It would certainly be a dreary outlook if natural science itself compelled us to accept the creed proclaimed by many of its modern prophets. Most dreary of all for one who has gained, from the content of natural science, the conviction that in its own sphere its mode of thought holds good and its methods are unassailable. For he is driven to make the admission that, however much people may dispute about individual questions, though volume after volume may be written, and thousands of observations accumulated about the struggle for existence and its insignificance, about the omnipotence or powerlessness of natural selection, natural science itself is moving in a direction which, within certain limits, must find acceptance in an ever-increasing degree.

But are the demands made by natural science really such as they are described by some of its representatives? That they are not so is proved by the method employed by these representatives themselves. The method they use in their own sphere is not such as is often described, and claimed for other spheres of thought. Would Darwin and Ernst Haeckel ever have made their great discoveries about the evolution of life if, instead of observing life and the structure of living beings, they had shut themselves up in a laboratory and there made chemical experiments with tissue cut out of an organism? Would Lyell have been able to describe the development of the crust of the earth if, instead of examining strata and their contents, he had scrutinised the chemical qualities of innumerable rocks? Let us really follow in the footsteps of these investigators who tower like giants in the domain of modern science. We shall then apply to the higher regions of spiritual life the methods they have used in the study of nature. We shall not then believe we have understood the nature of the "divine" tragedy of Hamlet by saying that a wonderful chemical process transformed a certain quantity of food into that tragedy. We shall believe it as little as an investigator of nature could seriously believe that he has understood the mission of heat in the evolution of the earth, when he has studied the action of heat on sulphur in a retort. Neither does he attempt to understand the construction of the human brain by examining the effect of liquid potash on a fragment of it, but rather by inquiring how the brain has, in the course of evolution, been developed out of the organs of lower organisms.

It is therefore quite true that one who is investigating the nature of spirit can do nothing better than learn from natural science. He need only do as science does, but he must not allow himself to be misled by what individual representatives of natural science would dictate to him. He must investigate in the spiritual as they do in the physical domain, but he need not adopt the opinions they entertain about the spiritual world, confused as they are by their exclusive contemplation of physical phenomena.

We shall only be acting in the spirit of natural science if we study the spiritual development of man as impartially as the naturalist observes the sense-world. We shall then certainly be led, in the domain of spiritual life, to a kind of contemplation which differs from that of the naturalist as geology differs from pure physics and biology from chemistry. We shall be led up to higher methods, which cannot, it is true, be those of natural science, though quite conformable with the spirit of it. Such methods alone are able to bring us to the heart of spiritual developments, such as that of Christianity, or other worlds of religious conceptions. Any one applying these methods may arouse the opposition of many who believe they are thinking scientifically, but he will know himself, for all that, to be in full accord with a genuinely scientific method of thought.

An investigator of this kind must also go beyond a merely historical examination of the documents relating to spiritual life. This is necessary just on account of the attitude he has acquired from his study of natural history. When a chemical law is explained, it is of small use to describe the retorts, dishes, and pincers which have led to the discovery of the law. And it is just as useless, when explaining the origin of Christianity, to ascertain the historical sources drawn upon by the Evangelist St. Luke, or those from which the "hidden revelation" of St. John is compiled. History can in this case be only the outer court to research proper. It is not by tracing the historical origin of documents that we shall discover anything about the dominant ideas in the writings of Moses or in the traditions of the Greek mystics. These documents are only the outer expression for the ideas. Nor does the naturalist who is investigating the nature of man trouble about the origin of the word "man," or the way in which it has developed in a language. He keeps to the thing, not to the word in which it finds expression. And in studying spiritual life we must likewise abide by the spirit and not by outer documents.

THE MYSTERIES AND THEIR WISDOM

A kind of mysterious veil hangs over the manner in which spiritual needs were satisfied during the older civilisations by those who sought a deeper religious life and fuller knowledge than the popular religions offered. If we inquire how these needs were satisfied, we find ourselves led into the dim twilight of the mysteries, and the individual seeking them disappears for a time from our observation. We see how it is that the popular religions cannot give him what his heart desires. He acknowledges the existence of the gods, but knows that the ordinary ideas about them do not solve the great problems of existence. He seeks a wisdom which is jealously guarded by a community of priest-sages. His aspiring soul seeks a refuge in this community. If he is found by the sages to be sufficiently prepared, he is led up by them, step by step, to higher knowledge, in places hidden from the eyes of outward observers. What then happens to him is concealed from the uninitiated. He seems for a time to be entirely removed from earthly life and to be transported into a hidden world.

When he reappears in the light of day a different, quite transformed
