I dont agree with Lenninger on the feminist arguement. Prospero in my opinion acted the way any father of any time period would act. It's not like Miranda is a 25 year old woman. She is only 15. She needs someone to keep her in check. And I feel when Prospero said "My foot, my tutor"
he was saying it in jest and not to be malicious or in a way to put Miranda down. After all, it is a comedy.
