Henry Stephens Salt said this quote

There areheights and valleys which, to those who seekthem in a sympathetic spirit, are better seats of learning than any school or university in the land ; there are days when the climber seems to rise into a rarer mental as well as visual atmosphere, and to leave far below him the crass cares and prejudices of commonplace life.
