Thomas Paine on Being "Temperate and Moderate"

Liberty Letters, Thomas Paine

Those words, “temperate and moderate,” are words either of political cowardice, or of cunning, or seduction. — A thing, moderately good is not so good as it ought to be. Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
