That appears very reasonable. And yet for a century people have been worrying themselves as to how it is with the hundred possible and the hundred actual thalers. But let us take a very obvious point of view, that of practical life; can one say from this point of view that a hundred actual thalers do not contain more than a hundred possible ones? One can say that a hundred actual thalers contain exactly a hundred thalers more than do a hundred possible ones! And it is quite clear: if you think of a hundred possible thalers on one side and of a hundred actual thalers on the other, there is a difference. On this other side there are exactly a hundred thalers more. And in most real cases it is just on the hundred actual thalers that the question turns.
