Cleanth

"Cleanth and fresh air — that's what I believe in. Throw open the doors and the windows. Let's have some fresh air in here."

The Victorians didn't place the highest of priorities on cleanth, and Kingsley played no small part in proselytizing the cause of cleanliness as being part of the godliness business.

'Purity' and 'pollution', the results of 'good' and 'bad' practice respectively, connote spiritual cleanliness and uncleanliness as well as literal 'cleanth' and filth.
