Based on a series of lectures given by Leonard Peikoff in 1981, Principles of Grammar offers not only an organized survey of grammatical rules and principles but their connection to the principles of clear thinking and clear writing. "At the end of the course," says Dr. Peikoff, "you should be able to see every grammatical rule, directly or indirectly, as a consequence or expression of some essential requirement of the human mind," not "a simply a hodge-podge of memorized rules that make no sense. ... I hope that [the course will give you] a sense of logic and security. Logic in regard to understanding the nature of grammatical issues-why they are as they are-and therefore security in regard to the whole subject. You will know the purpose, the rationale of the rules, and so I hope you will be able to think at the end that you can now make decisions on your own dubious or controversial cases. You don't have to rely helplessly on authorities."About the Author: Leonard PeikoffLeonard Peikoff is the preeminent Ayn Rand scholar writing today.
