Memorization has gotten a bad rap recently. Lots of students, and even some educators, say that being able to reason is more important than knowing facts; and besides, why bother committing things to memory when you've got Google? My response to this - after I've finished inwardly groaning - is that of course reasoning is important, but that doesn't mean you shouldn't know facts as well. It's not like you have to choose between one or the other. Besides, facts give you a foundation on which to reason about things.
