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

We must remember that all through this argument Burke is engaged in a piece of special pleading. He does not appear in the role of an impartial judge but as a warm and skilful advocate. As a matter of fact, though there was very little deviation from formal law in the Revolution of 1688, there was a profound change in the spirit and disposition and sentiment of the nation towards the monarchy, and Burke fights shy of this very significant fact.
