Having proved that, in accordance with this theory, you may regard the forest as an organism, you fancy that you have proved to the disciples of the organic doctrine the error of their definition. Nothing of the sort. The definition which they give to the organism is so inaccurate and so elastic that under this definition they may include what they will. "Yes," they say; "and the forest may also be regarded as an organism. The forest is mutual re-action of individuals, which do not annihilate each other,--an aggregate; its parts may also enter into a more intimate union, as the hive of bees constitutes itself an organism." Then you will say, "If that is so, then the birds and the insects and the grass of this forest, which re-act upon each other, and do not destroy each other, may also be regarded as one organism, in company with the trees." And to this also they will agree. Every collection of living individuals, which re-act upon each other, and do not destroy each other, may be regarded as organisms, according to their theory. You may affirm a connection and interaction between whatever you choose, and, according to evolution, you may affirm, that, out of whatever you please, any other thing that you please may proceed, in a very long period of time. And the most remarkable thing of all is, that this same identical positive science recognizes the scientific method as the sign of true knowledge, and has itself defined what it designates as the scientific method. By the scientific method it means common-sense. And common-sense convicts it at every step. As soon as the Popes felt that nothing holy remained in them, they called themselves most holy. As soon as science felt that no common-sense was left in her she called herself sensible, that is to say, scientific science. CHAPTER III. Division of labor is the law of all existing things, and, therefore, it should be present in human societies. It is very possible that this is so; but still the question remains, Of what nature is that division of labor which I behold in my human society? is it that division of labor which should exist? And if people regard a certain division of labor as unreasonable and unjust, then no science whatever can convince men that that should exist which they regard as unreasonable and unjust.
