A lot of what is discussed in the article reminds me of the book How to Re-Imagine the World by Anthony Weston. Much like the Center, Prof. Weston suggests right from the beginning of his book that "[A]ffirmative vision is crucial. Be emphatically, visibly, clear-headedly for something, and something that is worked out, widely compelling, and beautiful--not just against the problems or the powers-that-be of the moment."
Imagining an ideal future may seem silly--why waste time thinking about something that will never be?--but by aiming high an organization can hit lots of other incredible and valuable goals along the way while being stimulated and motivated by a dream of a wonderful future. That doesn't sound like a worthless exercise to me, but rather time well spent.
