The Future of Spanish

A few days ago I recommended Mathew Stewart's The Courtier and the Heretic, Leibnitz, Spinoza and the Fate of God in the Modern World, which I have found informative and very good reading. It has an excellent Bibliography of primary and secondary sources in English, French, German, Italian... but not a single entry in Spanish! Alas! No further comment, and you can draw your own conclusions, in the light of the title of this reflection.
