Implications of the affirming the priority of the common good

I've long wanted to understand more deeply what was at issue when Jacques Maritain and Charles De Koninck famously disagreed about the nature of the common good (and the individual person's relation thereto).  The recent translation, by Ralph McInerny, and publication, by the University of Notre Press, of The Writings of Charles De Koninck (2009) have been a great help (to me).  This link, to a blog I recently discovered and like a lot, states the terms of the debate with remarkable economy.
