^Iain McLean and Alistair McMillan, "Conservatism", Concise Oxford Dictionary of Politics, Third Edition, "Sometimes it (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.", Oxford University Press, 2009, ISBN 978-0-19-920516-5.
