Obama in Tucson: "What we can’t do is use this tragedy as one more occasion to turn on one another."

"As we discuss these issues, let each of us do so with a good dose of humility. Rather than pointing fingers or assigning blame, let us use this occasion to expand our moral imaginations, to listen to each other more carefully, to sharpen our instincts for empathy, and remind ourselves of all the ways our hopes and dreams are bound together."

This theme of humility was reinforced with the musical selection that followed: The choir sang the old Shaker hymn "Simple Gifts"...

'Tis the gift to be simple, 'tis the gift to be free,
'Tis the gift to come down where we ought to be,
And when we find ourselves in the place just right,
'Twill be in the valley of love and delight.
When true simplicity is gain'd,
To bow and to bend we shan't be asham'd....
