+274. Some men serving others. Freedom and equality. Figurative use of "slavery."+ Must we infer, then, that there is a social necessity that some men must serve others? In the New Testament it is taught that willing and voluntary service of others is the highest duty and glory of human life. If one man's strength is spent on another man's struggle for existence, the survival of the former in the competition of life is impaired. The men of talent are constantly forced to serve the rest. They make the discoveries and inventions, order the battles, write the books, and produce the works of art. The benefit and enjoyment go to the whole. There are those who joyfully order their own lives so that they may serve the welfare of mankind. The whole problem of mutual service is the great problem of societal organization. Is it a dream, then, that all men should ever be free and equal? It is at least evident that here ethical notions have been interjected into social relations, with the result that we have been taught to think of free and equal units willingly serving each other. That, at least, is an idealistic dream. Yet it no more follows from the fact that slavery has done good work in the history of civilization that slavery should forever endure than it follows from the fact that war has done good work in the history of civilization that war is, in itself, a good thing. Slavery alleviated the status of women; the domestication of beasts of draft and burden alleviated the status of slaves; we shall see below that serfs got freedom when wind, falling water, and steam were loaded with the heavy tasks. Just now the heavy burdens are borne by steam; electricity is just coming into use to help bear them. Steam and electricity at last mean coal, and the amount of coal in the globe is an arithmetical fact. When the coal is used up will slavery once more begin? One thing only can be affirmed with confidence; that is, that as no philosophical dogmas caused slavery to be abolished, so no philosophical dogmas can prevent its reintroduction if economic changes should make it fit and suitable again. As steam has had put upon it the hard work of life during the last two hundred years, the men have been emancipated from ancient hard conditions and burdens, and the generalities of the philosophers about liberty have easily won greater and greater faith and currency. However, the mass of mankind, taught to believe that they ought to have easy and pleasant times here, begin to complain again about "wages slavery," "debt slavery," "rent slavery," "sin slavery," "war slavery," "marriage slavery," etc. What men do not like they call "slavery," and so prove that it ought not to be. It appears to be still in their experience that a free man is oppressed by contracts of wages, debt, rent, and marriage, and that the cost
