Many of the problem areas in the law of contracts stem from the historical fact that the law of contracts has been fashioned out of material that does not fit together logically. Some jurists view contracts as conventions serving to secure people's expectations. These jurists, who support their approach by invoking the allied philosophical traditions of utilitarianism and pragmatism, have tried to make the law of contracts a device to protect parties who rely on promised advantages. Therefore, these jurists want law-enforcement processes to make people live up to the expectations they arouse in others.
