I saw this statement for the first time on a framed print in a stairwell in Washington Hall at Carlisle Barracks in Pennsylvania. I was there for a couple nights on a work trip, and the statement seemed so apropos that I took a picture. About a year later I was in an office where my coworkers needed to hear something like this, so I printed it, framed it, and hung it on my cubical wall (the original is in storage right now; this is a rendering with a little more texture to the background).
I'm not sure that it triggered any profound changes, but I am sure that everyone got the point.
