Known for quips about such things as “known knowns” and “known unknowns,” Mr. Rumsfeld says the game will sharpen the mind and help improve concentration. Whether it counteracts the effects of aging, he won’t precisely say. “It is helpful to know what you know and know what you don’t know, and in this case, I know what I think but I don’t know the answer to your question,” he said.

Donald Rumsfeld, the man who helped nudge the United States into a global war, has adapted a version of Solitaire that Winston Churchill played for the contemporary gaming crowd. It’s a strange footnote in American tragedy, but it is also a wonderful knot that ties together game playing, Slavoj Zizek, and the wonders of not knowing what we know. Zizek famously read Rumsfeld as a strange interlocutor of psychoanalysis, and now we have that man making a game about making jumps and skips based on known and unknown knowns. Perfect.
