Augustine argues that committing the Scriptures to memory is critical to understanding. Once the reader is "familiar with the language of Scripture," it is possible for him to try to untangle sections that are obscure. He also emphasizes studying the Scriptures in their original languages to avoid the problems of imperfect and divergent translations. Throughout Book Two, Augustine stresses the importance of method as well as virtue for attaining wisdom through the Scriptures. He analyzes sources of knowledge, reason, and eloquence as well as charity and humility.
