ONE:CHAPTER XXXIII. SHAPING MACHINES.His analysis of individuality was the first step in this direction. We have seen that he treats definition as a process of gradual specification, beginning with the most general notions, and working down by successive differentiations to the most particular. Now, the completed conception is itself the integration of all these differences, the bond of union holding them together. Turning to an antithetical order of ideas, to the material substance of which bodies are composed, and its various transformations, we find him working out the same vein of thought. According to the Aristotelian chemistry, an ultimate indeterminate unknowable something clothes itself with one or other of the opposing attributes, dry and moist, hot and cold; and when two of these are combined, manifests itself to our senses as one of the four elements. The elements combine in a particular manner to form homogeneous animal tissues, and these again are united into heterogeneous organs, which together constitute the living body. Here, then, we have two analogous series of specificationsone conceptual and leading down from the abstract to the concrete, the other physical, and leading up from the vague, the simple, and the homogeneous, to the definite, the complex, and the heterogeneous. Aristotle embraces both processes under a single comprehensive generalisation. He describes each of them as the continuous conversion of a346 possibility into an actuality. For the sake of greater clearness, let us take the liberty of substituting modern scientific terms for his cumbrous and obsolete classifications. We shall then say that the general notion, living thing, contains under it the two less general notionsplant and animal. If we only know of any given object that it has life, there is implied the possibility of its being either the one or the other, but not both together. On determining it to be (say) an animal, we actualise one of the possibilities. But the actualisation is only relative, and immediately becomes the possibility of being either a vertebrate or an invertebrate animal. The actuality vertebrate becomes the possibility of viviparous or oviparous, and so on through successive differentiations until we come (say) to a man. Now let us begin at the material end. Here are a mass of molecules, which, in their actual state are only carbon, nitrogen, and so forth. But they are potential starch, gluten, water, or any other article of food that might be named; for under favourable conditions they will combine to form it. Once actualised as such, they are possible blood-cells; these are possible tissues; these, again, possible organs, and lastly we come to the consensus of vital functions, which is a man. What the raw material is to the finished product, that are the parts to the entire organism, the elements to the compound, the genus to the species, and such in its very widest sense is potency to realisation, δ?ναμι? to ?ντελ?χεια, throughout the universe of growth and decay.246
TWO:On August 12th I came for the first time to Tongres. They had been there only a few days, and only near the town-hall did I see a goodly number of the garrison. Many wounded were brought there, and carried in through the door under the outside stairway. They came from Haelen, where a battle was being fought that afternoon and for which they had left in the morning. For the attack on the entrenched Belgians they had used cavalry exclusively, who were simply mowed down by the murderous fire from the hidden mitrailleuses and the infantry fire from the trenches. The Germans suffered a great reverse, and were deeply embittered.The keynote of the whole poem is struck in its opening lines. When Venus is addressed as Natures sole guide and ruler, this, from the poets own point of view, is not true of Nature as a whole, but it is eminently true of life, whether we identify Venus with the passion through which living things are continually regenerated, or with the pleasure which is their perpetual motive and their only good. And it is equally appropriate, equally characteristic of a consummate artist, that the interest of the work should culminate in a description of107 this same passion, no longer as the source of life, but as its last outcome and full flower, yet also, when pushed to excess, the illusion by which it is most utterly disappointed and undone; and that the whole should conclude with a description of death, not as exemplified in any individual tragedy, but in such havoc as was wrought by the famous plague at Athens on man and beast alike. Again, it is by the orderly sequence of vital phenomena that Lucretius proves his first great principle, the everlasting duration and changelessness of matter. If something can come out of nothing, he asks us, why is the production of all living things attached to certain conditions of place and season and parentage, according to their several kinds? Or if a decrease in the total sum of existence be possible, whence comes the inexhaustible supply of materials needed for the continual regeneration, growth, and nourishment of animal life? It is because our senses cannot detect the particles of matter by whose withdrawal visible objects gradually waste away that the existence of extremely minute atoms is assumed; and, so far, there is also a reference to inorganic bodies; but the porosity of matter is proved by the interstitial absorption of food and the searching penetration of cold; while the necessity of a vacuum is established by the ability of fish to move through the opposing stream. The generic differences supposed to exist among the atoms are inferred from the distinctions separating not only one animal species from another, but each individual from all others of the same species. The deflection of the atoms from the line of perpendicular descent is established by the existence of human free-will. So also, the analysis which distinguishes three determinate elements in the composition of the soul finds its justification in the diverse characters of animalsthe fierceness of the lion, the placidity of the ox, and the timorousness of the deerqualities arising from the preponderance of a fiery, an a?rial, and a windy ingredient in the animating principle of each respectively. Finally, by another organic108 illustration, the atoms in general are spoken of as semina rerumseeds of things.
