A surprising one, this, as sin is often presented, nowadays, as socially acceptable, even desirable ‘vice’ – something naughty-but-nice, essentially pleasurable and barely tainted by guilt (or is guilt the only sin left?)
Dante suggests instead that it wears the nerves to the point of collapse.
‘And if you l ike scum you might see the man
Sent to Vicenza by the Pope, before
Florence should see his sin-worn nerves collapse…’
For another angle on frayed nerves, see Steinbeck.
