Piron is the author of a book in French, Le bonheur clés en main (The Keys to Happiness), which distinguishes among pleasure, happiness and joy. He shows how one may avoid contributing to his own "anti-happiness" (l'anti-bonheur) and how one may expand the areas of happiness in his life. Piron's view is that, while one may desire happiness, desire is not enough. Just as people must do certain things in order to become physically stronger, they must do certain things in order to become happier. Those are the things that he describes in this book.
