Even I get fatigued sometimes sitting around trying to arrange the details of a better human world in my mind. It is one thing to speak eloquently of the better world, the "City on the Hill." Politicians must become adept at this. In my lifetime Robert F. Kennedy was the best at it for my money. It is quite another to get the detail right.
Obviously, perfect social justice is impossible. Therefore, in a better world there is only less social injustice and that which remains is of a more benign sort. But what does that mean in practice?
Perhaps, for another example, we can greatly reduce infant mortality. But then at what age is it acceptable for more children to die, as some must? Eight? Twelve?
I always hit the wall rather quickly on this sort of thing. When that happens, I must get out and enjoy the world as it is. Often this involves a walk in the park,
Parque Benito Juárez to be specific.
