In its semblance of simplicity this form of Evolution-philosophy shows itself kin to those other old-world attempts to dispense with a governing mind, and to educe the existing cosmos from the blind strife of primordial atoms. It has indeed a more plausible basis, seeing how many things, too quickly attributed to design in a theological age, can really be explained by the struggle for existence. But in trying to make an occasional and partial cause universal and ultimate, it has undertaken the impossible task of bringing the greater out of the less; which really means bringing their difference out of nothing--and this is creation with the First Cause left out; that is, spontaneous creation. It is from first to last an "aggregation" theory, and has to face the insupportable burdens which such a theory brings with it. Haunted by a false analogy drawn from the political organism whose members are intelligent and self-directive, and who put themselves under an intelligent government to be marshalled and directed to one common end--haunted by this anthropomorphic conception, it tries to explain how independent and indestructible units, void of all intelligence, come together into polities with no assignable government; and how these groups or polities, which are nothing separate from the sum of their components, are aggregated to one another in like manner; until at last we come to the highest organism, which again is only the sum of its ultimate atoms, and its activity the sum of their activities--the whole distinction between highest and lowest organism being such as exists between a society of two and a highly complex civilized state. And all this political life is the spontaneous work of unintelligent units; that is to say, we have results exceeding the highest ever attained by human intelligence, long before intelligence or sentience has yet been evolved.
