As I said in another connection: “An excellent plumber is infinitely more admirable than an incompetent philosopher. The society which scorns excellence in plumbing because plumbing is a humble activity and tolerates shoddiness in philosophy because it is an exalted activity will have neither good plumbing nor good philosophy. Neither its pipes nor its theories will hold water.”
¶ Excellence, Can We Be Equal and Excellent Too? (1961)
I think that all human systems require continuous renewal. They rigidify. They get stiff in the joints. They forget what they cared about. The forces against it are nostalgia and the enormous appeal of having things the way they have always been, appeals to a supposedly happy past. But we've got to move on.
