Contemporary wisdom about the necessity of smacking children was expressed in 1976 by an American psychologist. Dr James Dobson was so appalled by the widespread discarding of parental discipline that he wrote a book to explain the obvious: why children need smacking and what happens when smacking is not used.
For an explanation of the traditional use of discipline on children see the talk by Samuel Johnson (1709-1784).
