"The Temper of a Child misled by Vice or Mistake, like a dislocated Bone, is easie to be reduc'd into its Place, if taken in time; but if suffer'd to remain in its dislocated Position, a callous Substance fills up the empty Space, and by neglect grows equally hard with the Bone, and resisting the Power of the Surgeon's Skill, renders the Reduction of the Joynt impossible."
— Defoe, Daniel (1660?-1731)
