Unsurpassed for its clarity and comprehensiveness, A CONCISE INTRODUCTION TO LOGIC has established itself as the standard for introductory logic texts. In this Tenth Edition, Hurley continues to build upon the tradition of lucid, focused, and accessible presentations of logic's basic topics - both formal and informal. This edition also augments the book's successful technology integration with an updated and enhanced version of CengageNOW, which now includes Learning Logic tutorials, video clips, and the complete text in eBook format. In response to market feedback and the success of Wadsworth's Logical Choice custom program, this text has been reformatted to provide additional flexibility to customize your course material content.

大约两千五百年前，苏格拉底创建了一套方法，通过一系列探问，也就是后世所说的“苏格拉底方法”，来获取问题的答案，并对这些答案进行推断。通过这种方式，他就可以找出各种复杂现象背后的关键问题，揭开很多貌似有理实则荒谬的说法背后的真相。这套方法就是后来我们所说的“逻辑推理”
本质上来说，逻辑推理是一个“收集信息、评估信息的过程”。要想做出正确的决定，我们首先要占有充分的信息，而要想占有充分的信息，首先需要提出正确的问题。所以那些擅长逻辑推理的人，往往也比较善于提问，搜集相关信息，并用“正确的”方式 对这些信息进行评估。最重要的是，他们可以在不受他人干扰的情况下独立完成这一过程。
本书的目的，就是为读者提炼出一套最有用、最完整的逻辑推理概念，帮助读者在学习和现实生活中更好地理清思路，解决问题。
