Ways to Read

"One cannot read a book: one can only reread it."--Vladimir Nabokov

• "Speed reading is a collection of methods for increasing reading speed without an unacceptable reduction in comprehension or retention."

• Structure-Proposition-Evaluation (SPE) (Mortimer Adler's How to Read a Book) 
• Read
• (1) for the structure or outline; 
• (2) for the logical propositions made, organized into chains of inference; and 
• (3) for evaluation of the merits of arguments/conclusions. Suspend judgment until the work is fully understood.

• Survey-Question-Read-Recite-Review (SQ3R) reading toward being able to teach what is read
