The ability to reason is man's most important faculty - the attribute which lifts him above all other species. Yet, the science of using his rational faculty effectively has been almost entirely neglected. Most people fail to realize that thinking is not an automatic process, known to everyone "instinctively." It is, indeed, an acquired skill and - like every human skill - it involves certain principles which have to be identified and learned.

The Principles of Efficient Thinking was developed by Barbara Branden to help meet this need. Her course deals with thinking in both its theoretical and practical aspects. The theoretical aspect covers in detail the principles that make possible the most efficient use of one's mind; the practical aspect covers specific techniques by which one avoids thinking errors and maximizes the productiveness of one's mental effort.

As part of the curriculum of the Nathaniel Branden Institute (NBI), the course was attended by tens of thousands of students in cities throughout the United States and Canada. With the exception of lecture nine, which is a guest lecture by Nathaniel Branden, the course is given by Barbara Branden. Many of the lectures were re-recorded to improve sound quality, to slightly revise errors, to update references, and to make the contents readily understandable to those with no previous philosophical training. This course is substantially the same as that offered by NBI and it proved to be one of the most popular series offered by the Institute.
