"What we require is no new Revelation, but simply an adequate conception of the true essence of Christianity. And I believe that, as time goes on, the work of the Holy Spirit will be continuously shown in the gradual insight which the human race will attain into the true essence of the Christian religion. I am thus of opinion that a standing miracle exists, and that it has ever existed—a direct and continued influence exerted by the supernatural on the natural."—Paradoxical Philosophy.

For two hundred years the scientific world has been rent with discussions upon the Origin of Life. Two great schools have defended exactly opposite views—one that matter can spontaneously generate life, the other that life can only come from preëxisting life. The doctrine of Spontaneous Generation, as the first is called, has been revived within recent years by Dr. Bastian, after a series of elaborate experiments on the Beginnings of Life. Stated in his own words, his conclusion is this: "Both observation and experiment unmistakably testify to the fact that living matter is constantly being formed de novo, in obedience to the same laws and tendencies which determined all the more simple chemical combinations."[33] Life, that is to say, is not the Gift of Life. It is capable of springing into being of itself. It can be Spontaneously Generated.
This announcement called into the field a phalanx of observers, and the highest authorities in biological science engaged themselves afresh upon the problem. The experiments necessary to test the matter can be followed or repeated by any one possessing the slightest manipulative skill. Glass vessels are three-parts filled with infusions of hay or any organic matter. They are boiled to kill all germs of life, and hermetically sealed to exclude the outer air. The air inside, having been exposed to the boiling temperature for many hours, is supposed to be likewise dead; so that any life which may subsequently appear in the closed flasks must have sprung into being of itself. In Bastian's experiments, after every expedient to secure sterility, life did appear inside in myriad quantity. Therefore, he argued, it was spontaneously generated.
But the phalanx of observers found two errors in this calculation. Professor Tyndall repeated the same experiment, only with a precaution to insure absolute sterility suggested by the most recent science—a discovery of his own. After every care, he conceived there might still be undestroyed germs in the air inside the flasks. If the air were absolutely germless and pure, would the myriad-life appear? He manipulated his experimental vessels in an atmosphere which under the high test of optical purity—the most delicate known test—was absolutely germless. Here not a vestige of life appeared. He varied the experiment in every direction, but matter in the germless air never yielded life.
The other error was detected by Mr. Dallinger. He found among the lower forms of life the most surprising and indestructible vitality. Many animals could survive much higher temperatures than Dr. Bastian had applied to annihilate them. Some germs almost refused to be annihilated—they were all but fire-proof.
These experiments have practically closed the question. A decided and authoritative conclusion has now taken its place in science. So far as science can settle anything, this question is settled. The attempt to get the living out of the dead has failed. Spontaneous Generation has had to be given up. And it is now recognized on every hand that Life can only come from the touch of Life. Huxley categorically announces that the doctrine of Biogenesis, or life only from life, is "victorious along the whole line at the present day."[34] And even while confessing that he wishes the evidence were the other way, Tyndall is compelled to say, "I affirm that no shred of trustworthy experimental testimony exists to prove that life in our day has ever appeared independently of antecedent life."[35]
For much more than two hundred years a similar discussion has dragged its length through the religious world. Two great schools here also have defended exactly opposite views—one that the Spiritual Life in man can only come from preëxisting Life, the other that it can Spontaneously Generate itself. Taking its stand upon the initial statement of the Author of the Spiritual Life, one small school, in the face of derision and opposition, has persistently maintained the doctrine of Biogenesis. Another, larger and with greater pretension to philosophic form, has defended Spontaneous Generation. The weakness of the former school consists—though this has been much exaggerated—in its more or less general adherence to the extreme view that religion had nothing to do with the natural life; the weakness of the latter lay in yielding to the more fatal extreme that it had nothing to do with anything else. That man, being a worshiping animal by nature, ought to maintain certain relations to the Supreme Being, was indeed to some extent conceded by the naturalistic school, but religion itself we looked upon as a thing to be spontaneously generated by the evolution of character in the laboratory of common life.
The difference between the two positions is radical. Translating from the language of Science into that of Religion, the theory of Spontaneous Generation is simply that a man may become gradually better and better until in course of the process he reaches that quantity of religious nature known as Spiritual Life. This Life is not something added ab extra to the natural man; it is the normal and appropriate development of the natural man. Biogenesis opposes to this the whole doctrine of Regeneration. The Spiritual Life is the gift of the Living Spirit. The spiritual man is no mere development of the natural man. He is a New Creation born from Above. As well expect a hay infusion to become gradually more and more living until in course of the process it reached Vitality, as expect a man by becoming better and better to attain the Eternal Life.
