Punishment (n.) can backfire into desire: a spanking at eight left more longing than fear of its repetition.
Punishment (n.) when frequent is always a sign of a government's weakness: there is not a single ill-doer who could not be turned to some good.
Punishment (n.) should never come as punishment, only as the natural consequence of the fault: the liar should simply find he is not believed when he tells the truth.
Punishment (n.) repeated often enough becomes a price: beaten like a slave, he judged he had a right to all the vices of one, and stole in perfect tranquility.
Punishment (n.) can often be escaped by a worse fault: I was the victim of my scruples rather than my incontinence — my respect for marriage gave me away.
Punishment (n.) when harsh is a vain resource of little minds substituting terror for the respect they cannot win: where punishments are most severe they are most frequent, and equal severity for all faults drives men to crime to escape punishment.
Punishment (n.) is always a sign of weakness or supineness in a government. There is no knave that may not be made good for something. No one ought to be put to death, even for the sake of example, except the man who cannot be preserved without danger.
