Where we can study an actual working system of communism in such a climate as our own, we see that it only succeeded by some elaborate and very forcible regulations. To outsiders, ignorant of the machine, the less advanced states of society are generally supposed to be very simple, and to leave a large amount of liberty. On the contrary, whenever a barbaric or savage society is really understood, the complexity which is essential to its success is seen to be even greater than among ourselves. The movement of society has been from an earlier complexity of special restriction, to a later generalised simplicity. The whole of northern Europe appears to have had a very similar system of communal organisation, which has been mainly brought to light by the researches of Dr. Seebohm. The peace was kept by making every relation of a man responsible for his actions; either wounding in any degree, or murder, had to be compounded for by fines extending even to distant cousins, which were payable to the similar relations of the injured or murdered man. The immediate male relatives, father, son, brother, and first cousin, were responsible for two-thirds of the blood money, and other relations to the fifteenth degree made up the remainder. Thus the criminal law was communal in a full sense; and injuries were fully compensated in a manner which made every man his brother's keeper in a real communism. How would modern admirers of communism like to undertake the responsibilities of making up for the misdeeds of every relative? Yet that is an essential part of communal duties.
