and, since the time of Adam Smith, there has been no doubt at all about it.

If the landlord cultivates the land for his own profit and furnishes the capital he puts the profit on capital in his pocket as well as the ground-rent for it cannot be otherwise under existing conditions. And if Herr Duehring thinks that rent is something different when the lessee cultivates the land for himself it is not so and only shows his ignorance of the matter.
For example:—

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.
