It must further be grasped that the essential mark of the Servile Institution does not depend upon the ownership of the slave by a particular master. That the institution of slavery tends to that form under the various forces composing human nature and human society is probable enough. That if or when slavery were re-established in England a particular man would in time be found the slave not of Capitalism in general but of, say, the Shell Oil Trust in particular, is a very likely development; and we know that in societies where the institution was of immemorial antiquity such direct possession of the slave by the free man or corporation of free men had come to be the rule. But my point is that such a mark is not essential to the character of slavery. As an initial phase in the institution of slavery, or even as a permanent phase marking society for an indefinite time, it is perfectly easy to conceive of a whole class rendered servile by positive law, and compelled by such law to labour for the advantage of another non-servile free class, without any direct act of possession permitted to one man over the person of another. The final contrast thus established between slave and free might be maintained by the State guaranteeing to the _un-free_, security in their subsistence, to the free, security in their property and profits, rent and interest. What would mark the slave in such a society would be his belonging to that set or status which was compelled by no matter what definition to labour, and was thus cut off from the other set or status not compelled to labour, but free to labour or not as it willed. Again, the Servile State would certainly exist even though a man, being only compelled to labour during a portion of his time, were free to bargain and even to accumulate in his "free" time. The old lawyers used to distinguish between a serf "in gross" and a serf "regardant." A serf "in gross" was one who was a serf at all times and places, and not in respect to a particular lord. A serf "regardant" was a serf only in his bondage to serve a particular lord. He was free as against other men. And one might perfectly well have slaves who were only slaves "regardant" to a particular type of employment during particular hours. But they would be slaves none the less, and if their hours were many and their class numerous, the State which they supported would be a Servile State.
