§ 3. Definition for scientific use.
The present investigation is a sociological one; therefore our definition of slavery has to be sociologically relevant. We have to ask: What is the social value of slavery? Slavery is an organ in the social body performing a certain function, and we have to inquire: How is this organ developed, and how, in the various stages of its development, does it perform its function? But then we must know first what this organ and its function are. Thus only can we exclude from our inquiry organs somewhat resembling slavery, but functionally quite different from it, and organs wholly different from slavery, but performing the same function or nearly the same. And this is necessary; for the inclusion of such organs would create a confusion fatal to a right understanding.
What then is slavery and what is its function?
The great function of slavery can be no other than a division of labour[13]. Division of labour is taken here in the widest sense, as including not only a qualitative division, by which one man does one kind of work and another a different kind, but also a quantitative one, by which one man’s wants are provided for not by his own work only, but by another’s, A society without any division of labour would be one, in which each man worked for his own wants, and nobody for another’s; in any case but this there is a division of labour in this wider sense of the word. Now this division can be brought about by two means. “There are two ways” says Puchta, “in which we can avail ourselves of the strength of other men which we are in need of. One is the way of free commerce, that does not interfere with the liberty of the person who serves us, the making of contracts by which we exchange the strength and skill of another, or their products, for other performances [[8]]on our part: hire of services, purchase of manufactures, etc. The other way is the subjection of such persons, which enables us to dispose of their strength in our behalf, but at the same time injures the personality of the subjected. This subjection can be imagined as being restricted to certain purposes, for instance to the cultivation of the land, as with soil-tilling serfs; the result of which is that this subjection, for the very reason that is has a definite and limited aim, does not quite annul the liberty of the subjected. But the subjection can also be an unlimited one, as is the case when the subjected person, in the whole of his outward life, is treated as but a means to the purposes of the man of power, and so his personality is entirely absorbed. This is the institution of slavery”[14]. We have not much to add to this lucid description of slavery and its function. The function is a system of compulsory labour, and slavery is the absorption of the whole personality of the forced labourer to this end. As this absorption is properly expressed by the word “property” or “possession”, we may define the slave as a man who is the property or possession of another man, and forced to work for him.
This definition, however, on further consideration will show itself capable of some simplification. For when one man is the property of another, this implies compulsory labour. The right of property in this case, the object of it being a man, is a power over that man’s will too. The Romans recognised this: “The master has not only a right of property over the slave as over a lifeless thing, but also a power like that over his son, the potestas dominica, that is a power over the slave’s will”[15]. The right of property, that is a legally unlimited power over a man, were useless, if the owner did not influence the man’s will; and this influencing is equivalent to imposing labour upon him, labour being taken in the widest sense. A mere physical possession, such as the preserving of captives for cannibal purposes, which Letourneau and Spencer make so much of[16], is socially of little consequence. Possession of human beings, as a social institution, is that which gets hold [[9]]of the will of its object. Hence it follows, that slavery is the fact that one man is the property or possession of another.
This simplification of our formula has this advantage that, in inquiring whether in any country there are slaves, we need not ask whether there is labour imposed on subjected men. When this does not sufficiently appear, we need not say: We do not know whether slavery really exists here. When we are told that in such a country some men are the property of others (except of course the cases of mere physical possession we have hinted at, which are few and easy to recognise), we may be sure that they perform some kind of compulsory labour, and are justified in calling them slaves.
Further advantages of our definition are, that it is the definition given by many theorists, and that it lies within the limits of current speech.
In the following paragraphs we shall mark the distinction of slavery from some phenomena which somewhat resemble it. Of phenomena of this kind we shall consider only those that most frequently occur; other questionable cases will be examined in surveying the occurrence of slavery in the several parts of the globe.
