Now with regard to life in its relation to forms, change at the present time is coming over the thought of western Science. I pause on this for a moment in order to substantiate that assertion, for it is important in the search for the means of drawing together the two kinds of science, ancient and modern, to notice how much the position of the leading scientists of the West has been modified with regard to life and form during the last ten years. I take as a declaration on this subject of life, issued some years ago, the article on Biology in the last edition of the _Encyclopædia Britannica_, written, as all the articles in that _Cyclopædia_ are written, by a prominent man in the scientific world. In dealing then with life, the writer of the article in question distinctly states that "a mass of living protoplasm is simply a molecular machine of great complexity, the total results of the working of which, or its vital phenomena, depend, on the one hand, upon its construction, and on the other, upon the energy supplied to it and to speak of 'vitality' as anything but the name of a series of operations is as if any one should talk of the 'horologity' of a clock." That is to say, that to regard life as being in any sense a common existing principle, as anything more than a mere succession of phenomena in connection with a particular apparatus of matter, is as foolish and unreasonable as if, looking at a clock, you should separate its going property from the mechanism of the clock itself. A purely mechanical view of nature is thus taken, and life-processes are regarded as being due to the unstable equilibrium of protoplasm; the series of these life-processes is brought about merely by mechanical and chemical changes, the actions called vital being thus mechanical in their character. But at the last meeting of the British Association, the President of the Chemical Section--chemistry having been the very science to lead the scientific world towards materialism in this respect--has taken up an entirely different standpoint, a point that brings the question into a line with ancient thinking, and that starts the investigations of western Science along a road whereon the most fruitful results are likely to be encountered. Dr. Japp, the President of that Section, compares the action of life to the action of an operator who is deliberately working with a purpose, using knowledge and will in order to bring about a definite result. "The operator," he says, "exercises a guiding power which is akin, in its results, to that of the living organism," and, going on to explain in very technical language the ground on which this view is based, he concludes by saying: "Every purely mechanical explanation of the phenomenon must necessarily fail. I see no escape from the conclusion that at the moment when life first arose a directive force came into play--a force precisely of the same character as that which enables the intelligent operator, by the
