To this striking illustration I may also add that the social instinct is strongly developed with many lower animals, such as the land-crabs, or the Molucca crab; as also with certain fishes, with whom it hardly could be considered as an extension of the filial or parental feelings. In these cases it appears rather an extension of the _brotherly_ or _sisterly_ relations or feelings of _comradeship_, which probably develop each time that a considerable number of young animals, having been hatched at a given place and at a given moment, continue to live together--whether they are with their parents or not. It would seem, therefore, more correct to consider the social and the parental instincts as _two_ closely connected instincts, of which the former is perhaps the earlier, and therefore the stronger, and which both go hand in hand in the evolution of the animal world. Both are favoured by natural selection, which as soon as they come into conflict keeps the balance between the two, for the ultimate good of the species. To sum up all these ideas. We find it suggested that the social feelings from which morality sprang, were partly inherited by man from his animal ancestors, partly imitated from observation of the animals he knew so well in his wild life. And we find it suggested that these social feelings probably began in the love of animals for their young, and in the brotherhood and comradeship of the young for each other. It was the social feelings of men that made their Bibles: the Bibles did not make the social feelings. Morality is the result of evolution, not of revelation. CHAPTER FIVE--THE ANCESTRAL STRUGGLE WITHIN US I HAVE spoken of the "nature" handed down to us by our fore-parents. I might have said "natures," for our inheritance, being not from one, but from many, is not simple, but compound. We too commonly think of a man as an Englishman or a Frenchman; as a Londoner or a Yorkshireman; as good or bad. We too commonly think of a man as one person, instead of as a mixture of many persons. As though John Smith were _all_ John Smith, and _always_ John Smith. There is no such thing as an unmixed Englishman, Irishman, or Yorkshireman. There is no such thing as an unmixed John Smith. Englishmen are bred from the Ancient Briton, from the Roman, from the Piets and Scots, from the Saxons, the Danes, the Norwegians, the Normans, the French. All these varied and antagonistic bloods were mixed in centuries ago.
