Bertrand Russell: The subject will make great strides when it is taken up by scientists under a scientific dictatorship. The social psychologists of the future will have a number of classes of school children on whom they will try different methods of producing an unshakable conviction that snow is black. Various results will soon be arrived at. First that the influence of home is obstructive. Second that not much can be done unless indoctrination begins before the age of ten. Thirdly verses set to music and repeatedly intoned are very effective. Fourth that the opinion that snow is white must be held to show a morbid taste for eccentricity. But I anticipate. It is for future scientists to make these maxims precise and discover exactly how much it costs per head to make children believe that snow is black, and how much less it would cost to make them believe it is dark gray. https://wordsmith.social/protestation/quotes#quote7791
