Each "Briefly" volume provides a very short chapter setting the scene by explaining who this writer is and why this book in particular was so important, or why it became so important to Western thought.
This short contextualising chapter is then followed by an in-depth summary of the book in question.
This includes line by line analysis and short quotes to give students a feel for the original text.
Essentially a "Briefly" will allow students to become familiar with a key philosophical work in a very short time, but without missing out on the relevant parts of the original work.
A glossary of terms follows the summary to help students with definitions of philosophical terms.
