GK Chesterton 'The Well of Shadows'

 Men are progressive because they are a little behind the times. They are reactionary because they are a little in advance of the times. It sounds like a paradox; but it is really a very practical and even inevitable state of things, given certain conditions. Those behind will still cry "Forward!"; and only those far in front will cry "Back!"; when the vanguard of the army has come suddenly to the edge of a precipice.
