To write introduction to Brentari's monograph on Uexküll

I have been asked (by Marcello Barbieri, who is the book series editor along with Jesper Hoffmeyer), and agreed, to write the introduction chapter to Carlo Brentari's forthcoming monograph on Uexküll, which is entitled Jakob von Uexküll. The discovery of the Umwelt between biosemiotics and theoretical biology. An Italian version of the book already exist, this book, which will appear in Springer's Biosemiotics book series, is a translation from Italian. I will write the introduction at some point next year.
