"a man has not begun to live until he can rise above the narrow confines of his own individual concerns to the broader concerns of all humanity."

     Martin Luther King, Jr., "The three dimensions of a complete life," New Covenant Baptist Church, Chicago, Illinois, 9 April 1967, often bowdlerized as (for example) "An individual has not started living until they can rise above the narrow confines of their individualistic concerns to the broader concerns of all humanity."
     Apparently, though, King preached this sermon more than once, as (for example) already here at the Dexter Avenue Baptist Church of Montgomery, Alabama on 24 January 1954 (?):  "No man has lerned to live until he can rise out of his mere concern for self to the broader concern for others."
