Book excerpt: From the author of the bestselling How to Read a Book comes a comprehensive and practical guide for learning how to speak and listen more effectively. With over half a million copies in print of his “living classic” How to Read a Book in print, intellectual, philosopher, and academic Mortimer J. Adler set out to write an accompanying volume on speaking and listening, offering the impressive depth of knowledge and accessible panache that distinguished his first book. In How to Speak How to Listen, Adler explains the fundamental principles of communicating through speech, with sections on such specialized presentations as the sales talk, the lecture, and question-and-answer sessions and advice on effective listening and learning by discussion.
