This is by far the best book in any language on Valla as a philosopher. It will immediately take its place on graduate reading lists and in courses on Renaissance humanism and philosophy, and bring Valla into the narrative of Western philosophical history as no book has previously succeeded in doing.
   --James Hankins

Tremendously impressive. This is a welcome development in scholarship on Valla. Nauta has written a book that will be consulted for a long time to come.
