Punishment as two-sided form

“The penalty transforms, modifies, establishes signs, arranges obstacles. What use would it be if it had to be permanent? A penalty that had no end would be contradictory: all the constraints that is imposes on the convict and of which, having become virtuous once more, he would never be able to take advantage, would be little better than torture; and the effort made to reform him would be so much trouble and expense lost by society.”–Foucault
