+CONTENTS
+...
+I should have called my book The Art of Virtue,[72] because
+it would have shown the means and manner of obtaining virtue, which
+would have distinguished it from the mere exhortation to be good, that
+does not instruct and indicate the means, but is like the apostle's
+man of verbal charity, who only without showing to the naked and
+hungry how or where they might get clothes or victuals, exhorted them
+to be fed and clothed.--James ii. 15, 16.
