Mortimer Adler and Charles Van Doren’s 1940 classic How to Read a Book emphasized the four main levels of reading: elementary reading, inspectional reading, analytical reading, and syntopical reading. The book provides everything a learner needs to know and do to progress through and fully function at all levels.
