I am opposed to holistic social engineering. I refuse, however, to pour out the baby with the bath water and I am a long way from thinking that people should give up altogether on a constant search for ways of improving the world in which they must live together. It must be done even though they may never achieve more than partial improvements in particular areas, will always have to wait to see whether the change was the right thing to do, and must always be prepared to rectify whatever life has shown to be wrong.
