Keith was surprised when his boss invited a co-worker to lunch but did not invite him. at first, keith was convinced that he had not been invited because they wanted to discuss keith's job performance at lunch. later, the co-worker told keith that the boss had taken her to lunch to tell her that she was being laid off. privately, keith was relieved because it now made perfect sense to him why he had not been invited to lunch. in this scenario, keith appears to be: experiencing delusions of grandeur. suffering from delusions of persecution. suffering from delusions of being controlled. having normal thought processes.

Norman jones, an economic historian at the university of utah, has described the views of the ancient greek philosopher aristotle on interest: aristotle defined money as a good that was consumed by use. unlike houses and fields, which are not destroyed by use, money must be spent to be used. there- fore, as we cannot rent food, so we cannot rent money. moreover, money does not reproduce. a house or a flock can produce new value by use, so it is not unreasonable to ask for a return on their use. money, being barren, should not, therefore, be expected to produce excess value. thus, interest is unnatural. what did aristotle mean in arguing that money is “barren”? why would money being barren mean that lenders should not charge interest on loans? do you agree with aristotle’s reasoning? briefly explain.
