“A student who does not want his labor wasted must so read and reread some good writer so that the author is changed, as it were, into his flesh and blood. For a great variety of reading confuses and does not teach.
It makes the student like a man who dwells everywhere and, therefore, nowhere in particular. Just as we do not daily enjoy the society of every one of our friends but only that of a chosen few, so it should also be in our studying.”
–Martin Luther, What Luther Says: An Anthology, comp. Ewald M. Plass (St. Louis: Concordia Publishing House, 1959), entry no. 344, 112.
