Four months after Emmanuel Macron became president of France, the French and the rest of Europe still don't know what they are getting.

Bookstore shelves in France are filling with instant books on him, but they are cursory looks at the surface, and there's not much to go on compared with previous presidents of France like de Gaulle or Mitterrand, let alone Sarkozy or Hollande.

Regis Debray, now at age 80 the grand old man of French political intellectualism, has a new book out arguing that Macron represents the triumph of "neo-Protestant globalization" over "Catholic laicism" — whatever that means.
