↑McLean, Iain; McMillan, Alistair (2009). "Conservatism". Concise Oxford Dictionary of Politics (3rd ed.). Oxford University Press. "Sometimes [conservatism] has been outright opposition, based on an existing model of society that is considered right for all time. It can take a 'reactionary' form, harking back to, and attempting to reconstruct, forms of society which existed in an earlier period". ISBN978-0-19-920516-5.
