Fra Angelico, The Conversion of St. Augustine
"We must never assume that we now exactly what is happening when anyone else reads a book...The same book can move another's will and understanding differently than it does our own. We ourselves are receptive to different books at different times in our lives. It is quite possible for one to get nothing out of reading a book, whereas someone else, reading the same book, goes out and changes the world. Likewise we can be excited by reading a book that our friends find dull. There is a mystery here of how mind speaks to mind through reading."
-C.S. Lewis & Fr. James V. Schall, The Life of the Mind
