金岳霖是中国哲学知识沦研究领域的开拓者。《知识论》围绕“以经验之所得还治经验”这一主旨，自觉地将逻辑分析方法严格而系统地运用于哲学研究，特别注重思想的清晰性和论证性，系统地论述了知识的来源、知识的形成以及知识的可靠性、衡量真假的标准等问题。弥补了中国知识论不发达的缺陷，改变了中国传统哲学文本的写作模式。

人们直觉上认为，逻辑学独立于一般的哲学分支，与现实生活无涉。这本通俗诙谐的逻辑学普及读物告诉你，这样的想法实在是大错特错。上帝的存在、时间的流逝、概率的计算及决策的制定居然都是逻辑学研究的问题！本书抛弃了艰涩的术语，用最简明的方式介绍了形式逻辑学的基础知识，其中不乏精彩捧腹之处。

墨家逻辑和亚里士多德逻辑是人类思维史上两个最具典型意义的逻辑形态，它们分别对东方和西方的文化、思想等都产生了重大影响，形成了两种不同的思维路向。本书将逻辑放入文化这个大的视野下，以两种逻辑产生的文化背景为依据，采用历史分析与文化诠释、求同与求异相结合的方式，阐明了两种逻辑形态在目的和任务、主导推理类型、推理成分的分析以及后续发展等方面的差异。由此说明：逻辑与文化的客观联系，一方面表现为文化对逻辑的制约，另一方面表现为逻辑对文化的影响，逻辑的研究应注入文化的诠释，文化的研究同样也需要逻辑的关照。

This introduction to first-order logic clearly works out the role of first-order logic in the foundations of mathematics, particularly the two basic questions of the range of the axiomatic method and of theorem-proving by machines. It covers several advanced topics not commonly treated in introductory texts, such as Fraisse's characterization of elementary equivalence, Lindstrom's theorem on the maximality of first-order logic, and the fundamentals of logic programming.

Unsurpassed for its clarity and comprehensiveness, Hurley's A CONCISE INTRODUCTION TO LOGIC is the #1 introductory logic textbook in the market. In this Eleventh Edition, Hurley continues to build upon the tradition of a lucid, focused, and accessible presentation of the basic subject matter of logic, both formal and informal. Hurley's extensive, carefully sequenced collection of exercises continue to guide students toward greater proficiency with the skills they are learning. Review "What I like perhaps most about Hurley's text is the organization of the material. His book introduces the material in step-by-step way building off of what was just learned the section before and adding just enough information to each section to simplify the whole process of learning logic." - David Weise, Gonzaga University "This is the "gold standard" of introductory logic texts." - Frank Ryan, Kent State University "It is the clearest text, with the best technology available." - Stephanie Semler, Radford University "Hurley's text provides a methodical introduction to the strategies and techniques usually covered in an introductory logic course, including both formal and informal topics. Numerous exercises provide plenty of opportunity for students to practice the skills they have learned." - Allyson Mount, Keene State College "Hurley's book is thorough and very accessible to instructors and students. One of the best logic texts on the market." - Paula Smithka, University of Southern Mississippi
