Corporal punishment is as humiliating for him who gives it as for him who receives it; it is ineffective besides. Neither shame nor physical pain have any other effect than a hardening one.
Rewards and punishments, to speak frankly, are the desk of the soul, that is, a means of enslaving a child's spirit, and better suited to provoke than to prevent deformities.
Speaking generally, punishment hardens and numbs, it produces concentration, it sharpens the consciousness of alienation, it strengthens the power of resistance.
All in all, punishment hardens and renders people more insensible; it concentrates; it increases the feeling of estrangement; it strengthens the power of resistance.
Misbehavior and punishment are not opposites that cancel each other - on the contrary they breed and reinforce each other.
Physical punishment teaches children that the larger, stronger person has the power to get his way, whether or not he is in the right, and they may resent this in the parent-for life.
The broad effects which can be obtained by punishment in man and beast, are the increase of fear, the sharpening of the sense of cunning, the mastery of the desires; so it is that punishment tames man, but does not make him "better.".
When we use punishment, our children are robbed of the opportunity to develop their own inner discipline-the ability to act with integrity, wisdom, compassion, and mercy when there is no external force holding them accountable for what they do.
I think we actually punish children out of their relationship with their bodies... we categorically separate mind and body and emotion and intellect.
