The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration.
Inside myself is a place where I live all alone and that is where I renew my springs that never dry up.
You can judge your age by the amount of pain you feel when you come in contact with a new idea.
We should so provide for old age that it may have no urgent wants of this world to absorb it from meditation on the next. It is awful to see the lean hands of dotage making a coffer of the grave.
