If the possessor of a units of money receives h additional units, then it is not at all true to say that he will value the total stock a + h exactly as highly as he had previously valued the stock a alone. Because he now has disposal over a larger stock, he will now value each unit less than he did before; but how much less will depend upon a whole series of individual circumstances, upon subjective valuations that will be different for each individual.
