这本书从逻辑语义学的角度介绍了法律语言。作为一种逻辑工具，Boguslaw Wolniewicz的情境形式本体论得到了改编。讨论的核心问题是规范性声明的含义，主要是法律规范。这本书的主要成果包括从情境的形式本体论的角度解释几个法律概念（包括法律事件、法律行为和法律规则）。此外，该书还得出结论，法律规范是逻辑意义上的句子，因此有些是正确的，有些是错误的，它们的逻辑价值并不取决于它们是否在立法过程中被采纳。最后，这本书认为，尽管顺序不是逻辑意义上的句子，也就是说，它们既不是真的，也不是假的，但顺序之间的语义关系类似于蕴涵、矛盾、对立和次对立。这本书还介绍了一些维特根斯坦风格的、建立在一阶逻辑基础上的道义逻辑。形式化结果适用于法律理论中的选定问题，包括法律规范的算法应用的可能性问题。
Introduction to the Semantics of Law (Law and Visual Jurisprudence, 6)
This book offers an introduction to the language of law from the perspective of logical semantics. As a logical tool, Boguslaw Wolniewicz’s formal ontology of situations is adapted. The central issue addressed is the meaning of normative statements, primarily legal norms. The main outcome of the book consists in explications of several legal notions (including legal events, legal acts and legal rules) in terms of the formal ontology of situations. In addition, the book concludes that legal norms are sentences in a logical sense, so some are true, while others are false, and that their logical value does not depend on whether or not they were adopted in the law-making process. Lastly, the book contends that there are semantic relations between orders that are similar to entailment, contradiction, opposition, and sub-opposition, despite the fact that orders are not sentences in a logical sense, i.e., they are neither true nor false.The book also presents some original Wittgenstein-style deontic logics built on the first order logic. The formal results are applied to selected problems in the theory of law, including the problem of the possibility of algorithmic application of legal norms.
