"The revenue derived from labor is called wages; that derived from stock by the person who manages or employs it is called profit. The revenue which proceeds from land is called rent and belongs altogether to the landlord. The revenue of the farmer is derived partly from his labor and partly from his stock.... When those three different sorts of labor belong to different persons they are readily distinguished, but when they belong to the same they are sometimes confounded with one another at least in common language. A gentleman who farms part of his own estate, after paying the expenses of cultivation, should gain both the rent of the landlord and the profit of the farmer. He is apt to denominate, however, his whole gain, profit, and thus confounds rent with profit, at least in common language. The greater part of our North American and West Indian planters are in this situation. They farm, the greater part of them, their own estates, and accordingly we seldom hear of the rent of a plantation but frequently of its profit.... A gardener who cultivates his own garden with his own hands, unites in his own person the three different characters of landlord, farmer, and laborer. His produce, therefore, should pay him the rent of the first, the profit of the second and the wages of the third. The whole, however, is commonly considered as the wages of his labor. Both rent and profit are in this case confounded with wages." This passage is in the sixth chapter of the first book of Adam Smith. The case of the landholder who tills his own land has been examined a hundred years ago and the doubts which perplex Herr Duehring so much are caused entirely by his own ignorance. _X. With Respect to the "Critical History"._ This which is the concluding portion of the Second Division of the work and which deals with Herr Duehring's estimates of economic writers is omitted as being of too limited and polemic a character for general interest. PART III CHAPTER IX SOCIALISM The first two chapters of this Division, which deal respectively with the historical and the theoretical sides of Socialism, are omitted. They have been already translated. The well known pamphlet "Socialism, Utopian and Scientific" contains both of them. The second has also been translated by R.C.K. Ensor and published in his "Modern Socialism." _Production._
