"The attitude of the conservative is basically wrong: change should not be opposed. Not in a root and branch sense. What the conservatives should demand and insist on is that any projected changes should be reversible. The deadly changes are those which are irreversible, like the British introducing Greeks into Cyprus. Or like taking the sparrow and the rabbit to Australia. So long as a projected change can be shown to be reversible there should be no very serious objection to making a tryout. If the first step along the new road turns out well, the second step can be made, but if it turns out badly one simply retreats to where one was before. This seems to me to be the essential principle of social change."
