We are always faced both with the question 'what must be destroyed?' and with the question 'what must be preserved?' and neither Liberalism nor Conservatism, which are not philosophies and may be merely habits, is enough to guide us.
From T.S. Eliot's The Idea of a Christian Society, 1938
T.S. Eliot's observation could be extended beyond politics into any antagonism of progressives vs. conservatives.
