Books are the sign-posts
Mosaic street sign-post in Ocean Grove, NJ
"... I forgot that we are no longer children: you cannot guess how much we men, and more than all, perhaps, we writers whose task it is to unravel the web of human actions, owe even to our own past errors; and if we learned nothing by the errors of others, we should be dull indeed. We must know where the roads divide, and have marked where they lead to, before we can erect our sign-post; and books are the sign-posts in human life."
