The old hunger for voyages fed at his heart....To go alone...into strange cities; to meet strange people and to pass again before they could know him; to wander, like his own legend, across the earth--it seemed to him there could be no better thing than that.

You can't go home again

Only the dead know Brooklyn.

A young man is so strong, so mad, so certain, and so lost. He has everything and he is able to use nothing.

The thought of these vast stacks of books would drive him mad: the more he read, the less he seemed to know — the greater the number of the books he read, the greater the immense uncountable number of those which he could never read would seem to be…. The thought that other books were waiting for him tore at his heart forever.

Loneliness is and always has been the central and inevitable experience of every man.
