severer manners
Note from Price's Sermon in Part One of Reflections On The Revolution In France

'Foundations of civil freedom in severer manners': cp. the Puritan 'regime' of the Cromwellian commonwealth. We may remember here that if France "when she let loose the reins of legal authority, doubled the licence of a ferocious dissoluteness in manners and of an insolent irreligion in opinions and practices," England did exactly the same when, at the Restoration in 1660, she submitted to similar reins.
