柏林提出的消极自由理念在政治哲学自由主义领域的研究具有里程碑式的意义，他认为消极自由是一个人可以不受外界一切因素干扰而完全按照自身意识行事的自由领域，是人一切自由的前提和本质。以此为理论基础，本文探讨了柏林的消极自由在法律中的应用，认为沉默权是消极自由的载体，无罪推定原是消极自由的保障。进一步地，结合米兰达规则，以典型案例分析的方式揭示了消极自由思想在法律过程中对维护人的基本权利的重要性。最后，本文对沉默权、无罪推定在中国应用前景进行了展望，以期能够从立法、司法和执法过程等方面对法律系统进行完善。

The concept about negative liberty Isaiah Berlin put forward is a milestone in the research of liberalism, which is an important part of political philosophy. In his opinion, negative liberty is that one person enjoys complete freedom to do as he wishes without any interference factors from the outside. Berlin regarded it as the premise and essence of liberty for human. On this basis, this paper discusses the application of negative liberty in laws, which consider right of silence as a carrier, and the safeguard is presumption of innocence. Furthermore, Miranda rule is a typical case shows the importance of negative liberty in protecting the fundamental rights of a man. In the end, we look the application of right of silence and presumption of innocence to the future in China, looking forward to perfecting the legal system from legislation, justice, and enforcement.
