"Happiness is the right of all children, and it is very wrong to make their lives difficult in order to prepare them for a life that may not contain enough elements to make them happy. This fundamental belief is hidden behind all schools that punish and frighten poor children; the belief that happiness is not a right, that it must be sacrificed for duty, ambition, to glorify proud parents and teachers. Education can be called today the system that kills children's happiness with desks and lessons, with fear and punishment [...] The basic principle that should govern all educational systems should be the condition of the child's happiness. A school should be judged by the faces of its students and not by its academic achievements".
(A. S. Neill, Talking of Summerhill)
