We want to see our people raised, not into a society of State ownership, but into a society in which, increasingly, the individual may become an owner. There is a very famous sentence of Sir Henry Maine's, in which he said that the progress of our civilisation had been of recent centuries a progress on the part of mankind from status to contract. Socialism would bring him back from contract to status.
