Darkness cannot drive out darkness

Darkness cannot drive out darkness;

only light can do that.

Hate cannot drive out hate;

only love can do that.

Hate multiplies hate,

violence multiplies violence,

and toughness multiplies toughness

in a descending spiral of destruction...

The chain reaction of evil --

hate begetting hate,

wars producing more wars --

must be broken, or we shall be plunged

into the darkness of annihilation.

Dr. Martin Luther King, Jr.

January 15, 1929 - April 4, 1968
