All this throws an important light upon two subjects which are relevant in this connection, but which cannot here be exhaustively dealt with,—evolution and new beginnings. Let us consider, for instance, the marvellous range and diversity of the characteristic chemical properties and interrelations of substances. Each one of them, contrasted with the preceding lower forms and stages of “energy,” contrasted with mere attraction, repulsion, gravitation, is something absolutely new, a new interpolation (of course not in regard to time but to grade), a phenomenon which cannot be “explained” by what has gone before. It simply occurs, and we find it in its own time and place. We may call this new emergence “evolution,” and we may use this term in connection with every new stage higher than those preceding it. But it is not evolution in a crude and quantitative sense, according to which the “more highly evolved” is nothing more than an addition and combination of what was already there; it is evolution in the old sense of the word, according to which the more developed is a higher analogue of the less developed, but is in its own way as independent, as much a new beginning as each of the antecedent stages, and therefore in the strict sense neither derivable from them nor reducible to them. It must be noted that in this sense evolution and new beginnings are already present at a very early stage in nature and are part of its essence. We must bear this in mind if we are rightly to understand the subtler processes in nature which we find emerging at a higher level. It is illusory to suppose that it is a “natural” assumption to “derive” the living from lower processes in nature. The non-living and the inorganic are also underivable as to their individual stages, and the leap from the inorganic to the organic is simply much greater than that from attraction in general to chemical affinity. As a matter of fact, the first occurrence—undoubtedly controlled and conditioned by internal necessity—of crystallisation, or of life, or of sensation has just the same marvellousness as everything individual and everything new in any ascending series in nature. In short, every new beginning has the same marvel.
