Quote: All politeness is owing to liberty. We polish one another, and rub off our corners and rough sides by a sort of amicable collision. To restrain this, is inevitably to bring a rust upon men’s understandings. — Anthony Nils Christian Ashley-Cooper, 10th Earl of Shaftesbury (1938–2004) British conservationist
