Slavish discipline makes a slavish temper... If severity carry'd to the
highest pitch does prevail, and works a cure upon the present unruly
distemper, it often brings in the room of it a worse and more dangerous
disease, by breaking the mind; and then, in the place of a disorderly young
fellow, you have a low spirited moap'd creature, who, however with his
unnatural sobriety he may please silly people, who commend tame unactive
children, because they make no noise, nor give them any trouble; yet at
last, will probably prove as uncomfortable a thing to his friends, as he
will be all his life an useless thing to himself and others... Beating them,
and all other sorts of slavish and corporal punishments, are not the
discipline fit to be used in the education of those we would have wise,
good, and ingenuous men...
John Locke, 1692
