Lecture I
But the matter has a deeper aspect. One can ask the question: What is the point in the difference between a hundred possible and a hundred actual thalers? I think it would be generally conceded that for anyone who can acquire the hundred thalers, there is beyond doubt a decided difference between a hundred possible thalers and a hundred actual ones. For imagine that you are in need of a hundred thalers, and somebody lets you choose whether he is to give you the hundred possible or the hundred actual thalers. If you can get the thalers, the whole point is the difference between the two kinds. But suppose you were so placed that you cannot in any way acquire the hundred thalers, then you might feel absolutely indifferent as to whether someone did not give you a hundred possible or a hundred actual thalers. When a person cannot have them, then a hundred actual and a hundred possible thalers are in fact of exactly the same value.
