Punishment (n.) can be dreamt as a wish: 'It would serve me right.'
Punishment (n.) suffered in childhood leaves ineradicable memories that fasten later on the ‘dies irae’ of our stiffest examinations.
Punishment (n.) meted out to the unpopular fits not their wrongdoing but their wrongdoing plus all the ill-feeling that had been waiting for an excuse.
Punishment (n.) began with taboo: first the violated taboo itself took vengeance, then the gods, and finally society — so the earliest penal systems trace back to taboo.
Punishment (n.) protects the punishers from themselves: if the violation went unavenged, they would become aware that they wanted to do the same.
Punishment (n.) lets the punishers commit the same outrage under colour of expiation — it rests on the assumption that the forbidden impulse lives alike in criminal and avenging community.
Punishment (n.) must be exacted for the unconscious even if it does not fall upon the guilty — like the village that hanged a tailor because its only blacksmith had committed the crime.
