VI.
THE INDIVIDUAL AND THE SPECIES.
It can also be shown that scientific socialism proceeds directly from Darwinism by an examination of the different modes of conceiving of the individual in relation to the species.
The eighteenth century closed with the exclusive glorification of the individual, of the man—as an entity in himself. In the works of Rousseau this was only a beneficent, though exaggerated re-action against the political and sacerdotal tyranny of the Middle Ages.
This individualism led directly to that artificiality in politics, which I will consider a little further on in studying the relations between the theory of evolution and socialism, and which is common to the ruling classes under the bourgeois regime and to the individualistic anarchists,—since both alike imagine that the social organization can be changed in a day by the magical effect of a bomb,—more or less murderous.
Modern biology has radically changed this conception of the individual and it has demonstrated, in the domain of biology as in that of sociology, that the individual is himself only an aggregation of more simple living elements, and likewise that the individual in himself, the Selbstwesen of the Germans, does not exist in independent isolation, but only as a member of a society (Gliedwesen).
Every living object is an association, a collectivity.
The monad itself, the living cell, the irreducible expression of biological individuality, is also an aggregate of various parts (nucleus, nucléole, protoplasm), and each one of them in its turn is an aggregate of molecules which are aggregates of atoms.
The atom does not exist alone, as an individual; the atom is invisible and impalpable and it does not live.
And the complexity of the aggregation, the federation of the parts constantly increases with the ascent in the zoological series from protozoa to Man.
