This is one of a series of comments in which Roger Jones extols the virtues 
of his understanding of second order logic. It's not a bad thing to find 
virtues where others find flaws, so I would invite Jones to provide a 
sample dialog in which these virtues become apparent, specifically in which 
some clear propositions are being communicated using second order validity 
in some essential manner. .
