塞缪尔·威利斯顿将学术生涯中大部分的精力都放在了对对价理论的探索上。对价理论展现了他最为理论化、客观化、形式化的一面。对价是英美合同法上存在的一种效力原则,它被认定为双务合同成立的最主要的要件,有了充分对价的存在,双务合同才能最终有效。严格来说,我国的合同法体系中并不存在这样的概念。对威利斯顿来说,对价理论的研究,不仅出于一种理论需要,而且出于一种现实需要。对他而言,对价理论的研究,并非出于对一种理论的单纯追求,而是要让它能够更好应用、服务于法律体系。
Samuel Williston devoted most of his academic career to exploring the theory of value. The theory of value shows his most theoretical, objective and formal aspects. Consideration is a principle of validity existing in the Anglo-American contract law. It is considered as the most important requirement for the establishment of a dual-service contract. With the full consideration, the dual-service contract can be finally valid. Strictly speaking, there is no such concept in the contract law system of our country. For Williston, the study of the theory of value is not only for a theoretical need, but also for a realistic need. For him, the study of the theory of value is not based solely on the pursuit of a theory, but rather on its application and service to the legal system.
