The Aural System Being the Most Direct, the Straight-Line Method for the Simultaneous Fourfold Mastery of a Foreign Language.

"The Aural System" by Charles Hardy is a book that presents a new way to learn a foreign language, focusing on mastering speaking, understanding, reading, and writing all at the same time. Hardy argues against old-fashioned teaching methods that focus too much on grammar, which he believes don't help students actually speak or understand the language. Instead, he suggests a complete learning method where students listen, speak, read, and write together, learning languages in a way that is similar to how children learn their first language. This technique is for students to learn with the help of instructors through listening exercises, speaking exercises, reading exercises, and writing practices. This would allow the students to better master the language in totality.
