But the earth presents the most perfect adjustment of internal relations to those that are external, and it continuously presents them. Even the upheaval of its fire-spitting mountains affords the highest demonstration of the adjustment of its inner terrestrial forces to those that are purely external; and much more does it show the adjustment of its internal to its external relations. There is a continuous adaptation of means to ends, of causes to effects, of adjustments to re-adjustments, in respect to the characteristics of the earth's surface--its physical configuration, the distribution of its fluids and solids, its fauna and flora, its hygrometric and thermometric conditions, its ocean, wind, and electro-magnetic currents, and even its meteorological manifestations--all showing a continuous adjustment of interior to exterior conditions or relations. The earth should, therefore, fall under the category of "life," according to Herbert Spencer's definitional formula. And so should an automatic dancing-jack that is made to run by internal adjustments to external movements or manifestations. There are any number of Professor Bastian's "ephemoromorphs" that do not live half as long as one of these automatic dancing-jacks will run, and so long as they run, the adjustment of their internal to their external relations is continuous. The success of Mr. Spencer's definition of "life" encouraged Professor Bastian to try his hand at it, with this definitional result: "Life," he says, "is an unstable collocation of Matter (with a big M), capable of growing by selection and interstitial appropriation of new matter (what new matter?) which then assumes similar qualities, of continually varying in composition in response to variations of its Medium (another big M), and which is capable of self-multiplication by the separation of portions of its own substance." It shall not be our fault if the reader fails to understand this definition--to untwist this formidable formula of life. And we can best aid him by grammatically analyzing its structure. And, 1. "Life is capable of growing." We are glad to know this. As a vitalist it enables us to take a step towards the front--gets us off the "back seat" to which we were summarily ordered at the outset of this inquiry. We let its "unstable collocation" pass for what it is worth, and stick to our grammatical analysis. 2. "Life grows--is capable of doing something." This assurance positively encourages us. 3. "It grows by selection and interstitial appropriation." This is still more encouraging. It emboldens us to take a second step forward. Life, we feel, is increasing in potentiality. 4. "By appropriation it enables _new matter to assume similar qualities to old matter_." This makes us more confident than ever; we take another step forward--are half disposed to take two of them. Life is getting to be almost a "potentiated potentiality," to adopt the style of materialistic phrases.
