The Other
Note to Ad Valorem from Unto This Last by John Ruskin

If Mr. Mill had wished to show the difference in result between consumption and sale, he should have represented the hardware merchant as consuming his own goods instead of selling them; similarly, the silver merchant as consuming his own goods instead of selling them. Had he done this, he would have made his position clearer, though less tenable; and perhaps this was the position he really intended to take, tacitly involving his theory, elsewhere stated, and shown in the sequel of this paper to be false, that demand for commodities is not demand for labour. But by the most diligent scrutiny of the paragraph now under examination, I cannot determine whether it is a fallacy pure and simple, or the half of one fallacy supported by the whole of a greater one; so that I treat it here on the kinder assumption that it is one fallacy only.
