“I have packed myself into silence so deeply and for so long that I can never unpack myself using words. When I speak, I only pack myself a little differently.”

Circulated in "A Coil of Rage" http://www.snopes.com/politics/obama/coilofrage.asp, a 2011 mass e-mail attributing several fabricated quotations to Obama.
Obama actually wrote, in Dreams from My Father, p. 220:
Yes, I'd seen weakness in other men — Gramps and his disappointments, Lolo [my adoptive father] and his compromise. But these men had become object lessons for me, men I might love but never emulate, <span style="color:gray">white men and brown men whose fates didn't speak to my own. It was into my father's image, the black man, son of Africa, that I'd packed all the attributes I sought in myself, the attributes of Martin and Malcolm, DuBois and Mandela.</span>

The Inferno (1917), Ch. XVII
Context: Who shall compose the Bible of human desire, the terrible and simple Bible of that which drives us from life to life, the Bible of our doings, our goings, our original fall? Who will dare to tell everything, who will have the genius to see everything?
I believe in a lofty form of poetry, in the work in which beauty will be mingled with beliefs. The more incapable of it I feel myself, the more I believe it to be possible. The sad splendour with which certain memories of mine overwhelm me, shows me that it is possible. Sometimes I myself have been sublime, I myself have been a masterpiece. Sometimes my visions have been mingled with a thrill of evidence so strong and so creative that the whole room has quivered with it like a forest, and there have been moments, in truth, when the silence cried out.
But I have stolen all this, and I have profited by it, thanks to the shamelessness of the truth revealed. At the point in space in which, by accident, I found myself, I had only to open my eyes and to stretch out my mendicant hands to accomplish more than a dream, to accomplish almost a work.
