When Thomas More wrote Utopia in 1516 he gave a name to a very old, perhaps universal, tradition of thinking that included the Epic of Gilgamesh, Plato's Republic and the Old Testament — and he started an argument. Francis Bacon (utopia through Science) and Jean Jacques Rousseau (utopia through Nature) soon joined the debate, but it was the harsh changes in daily life engendered by the factory systems of the early Industrial Revolution that brought an urgency to the discussion, as seen in the writings of David Owens, Karl Marx and Friedrich Engels.
