Dan Fuller:
Whenever someone is imparting understanding, or insight, or a new way of looking at things, he will always say things which seem strange and, at the outset, incoherent with other things that he is saying.
Mortmer Adler:
Perhaps you are beginning to see how essential a part of reading it is to be perplexed and know it. Wonder is the beginning of wisdom in learning from books as well as from nature. If you never ask yourself any questions about the meaning of a passage, you cannot expect the book to give you any insight you do not already possess.
