The author is Aneurin Bevan, an English labour politician from Winston Churchill´s era. He created the NHS and he had famous debates with Churchill in the Parliament.
The meaning of the quote seems to be clear, it is an inversion of the sentence "sin is its own punishment".
I would like to know when he wrote or said this quote, and who it was addressed to.
Also I would like to find out whether it happened while in a politic debate or if it was more of a religious/philosophic argument.
