Nathaniel Hawthorne said this quote

Possibly, he was in a state of second growth and recovery, and was constantly assimilating nutriment for his spirit and intellect from sights, sounds, and events which passed as a perfect void to persons more practised with the world. As all is activity and vicissitude to the new mind of a child, so might it be, likewise, to a mind that had undergone a kind of new creation, after its longsuspended life.
