法学对信任的关注,来源于社会信任危机的来临以及法律对信任危机干预的可能性。社会信任危机的社会本质是时空错乱,既表现为社会转型过程中的社会心理危机,也是制度转型的危机所在。在传统社会中,法律不能直接建立有效的社会预期,而是经由法律与社会规范的同构而形成。因此,传统社会中的信任与法律表现为弱相关关系。与此相对,现代社会中,法律无需通过社会规范这一桥梁就可以建立强有力的有效社会预期,使得法律与信任表现为强相关关系。社会信任危机的法律治理在于信任结构的法律改造,即在宏观上,通过改善社会结构,建构社会结构与法律制度一体化的社会系统,消除社会主体的时空错乱感;中观治理上,通过稳定的法律系统建构稳定的法律预期;微观上,则通过法律对不信任的干预,建立系统的社会信任保护机制和对不信任的惩罚机制。当然,社会信任危机的法律治理还需要治理法律自身,防止法律成为社会信任危机的源头。 Law concerns about trust come from the coming of the crisis of social trust and the possibility of law intervening in the crisis of confidence. The social nature of the social crisis of confidence is spatiotemporal confusion, which manifests itself both as a social-psychological crisis in the process of social transformation and as a crisis of institutional transition. In traditional society, the law can not directly establish effective social expectation, but formed by the isomorphism of law and social norms. Therefore, trust and law in traditional society show a weak correlation. In contrast, in modern society, law can establish strong and effective social expectations without going through the social norms, making law and trust a strong correlation. The legal governance of the social crisis of confidence lies in the legal reform of the trust structure. In macro terms, the social system integrating the social structure and the legal system is constructed through the improvement of the social structure and the time-space dislocation of the social subject is eliminated. Of the legal system to build a stable legal expectations; microscopically, through the law of non-trust intervention to establish a system of social trust protection mechanisms and mechanisms for the punishment of mistrust. Of course, the legal governance of the social crisis of confidence also needs to govern the law itself and prevent the law from becoming a source of social crisis of confidence.
