Prison monasteries

The Prison Farms thread gave me an idea for prison reform.  Rather than have prisoners go to the yard and and work out where they become more physical and stronger, why not have them adopt quiet lives of cerebral contemplation?

put on shock collars that forces a vow of silence and fill their days with meditation and transcribing texts.  In the spirit of reform and developing skills they can take on the humble arts of wine making.   

The vow of silence and near constant solitary breaks down gangs and other social orders.   The constant writing and copying of texts indoctrinates them in the great thinkers.  Self flagilation provides physical outlet and trains them to turn their aggression on themselves.  Ultimately driving home an idea subservience and humility to better serve society.
