arise, for where these do not exist society dissolves; society can only exist where these exist.
These instincts, while they have their origin in habit and necessity, are strengthened by the struggle for existence. Every animal herd still stands in a competitive struggle against the same animals of a different herd; those that are best fitted to withstand the enemy will survive, while those that are poorer equipped will perish. That group in which the social instinct is better developed will be able to hold its ground, while the group in which social instinct is low will either fall an easy prey to its enemies or will not be in a position to find favorable feeding places. These social instincts become therefore the most important and decisive factors that determine who shall survive in the struggle for existence. It is owing to this that the social instincts have been elevated to the position of predominant factors.
These relations throw an entirely new light upon the views of the bourgeois Darwinists. Their claim is that the extermination of the weak is natural and that it is necessary in order to prevent the corruption of the race, and that the protection given to the weak serves to deteriorate the race. But what do we see? In nature itself, in the animal world, we find that the weak are protected; that it is not by their own personal strength that they maintain themselves, and that they are not brushed aside on account of their personal weakness. This arrangement does not weaken the group, but gives to it new strength. The animal group in which mutual aid is best developed is best fit to maintain itself in the strife. That which, according to the narrow conception appeared as a cause of weakness, becomes just the reverse, a cause of strength.
