One of the problems we old geezers have is memory. Not only are we losing it, particularly the short-term variety, but to the extent we retain some, we can be immobilized by it.
Maybe that's the problem with the controversies over memorials. Memorials are signs, and important. but devote too much concern to the past and the future evades your grasp. Much better in my mind to err on the side of focusing on the future, than the past. (Yet, and yet, I tried to be a historian once--how does that fit? Don't know.)
