Sometimes guardians think it is necessary to slap a child, to slap its face. Slapping is sometimes dangerous, because there are veins and delicate organs in the forehead and on the temples, and slapping could cause a condition which though not manifest at the time, might become so after twenty or forty years. And therefore instead of slapping it is far better to tweak the ears. Punishment has a very bad effect when it blunts the sharpness of the child's spirit. Very often punishment may work with the child, but in some way or other it blunts its fineness; and therefore one must try to do without it if one can. Then, after giving good advice and counsel and encouragement, and after showing appreciation and doing everything possible, the last thing is to tweak the ears.
