had to arise which later developed to moral feelings. That our customs and morals are nothing other than social feelings, feelings that we find among animals, is known to all; even Darwin spoke about "the habits of animals which would be called moral among men." The difference is only in the measure of consciousness; as soon as these social feelings become clear to men, they assume the character of moral feelings. Here we see that the moral conception—which bourgeois authors considered as the main distinction between men and animals—is not common to men, but is a direct product of conditions existing in the animal world.
It is in the nature of the origin of these moral feelings that they do not spread further than the social group to which the animal or the man belongs. These feelings serve the practical object of keeping the group together; beyond this they are useless. In the animal world, the range and nature of the social group is determined by the circumstances of life, and therefore the group almost always remains the same. Among men, however, the groups, these social units, are ever changing in accordance with economic development, and this also changes the social instincts.
The original groups, the stems of the wild and barbarian people, were more strongly united than the animal groups. Family relationship and a common language strengthened this union further. Every individual had the support of the entire tribe. Under such conditions, the social motives, the moral feelings, the subordination of the individual to the whole, must have developed to the utmost. With the further development of society, the tribes are dissolved and their places are taken by new unions, by towns and peoples.
