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.

The most dangerous lies are the ones we believe about ourselves.

Be civil to all; sociable to many; familiar with few; friend to one; enemy to none.

The truth is that we are all capable of great evil, given the right circumstances.
