Book excerpt: The scope of this book is to provide items to understand how and why the Space Renaissance movement was conceived and was born. Therefore I collected hereafter the main works which stand in the background of the Space Renaissance philosophical elaboration, since 2008 (year of birth of the Space Renaissance very first concept), but even before, with some papers authored by the founder Adriano Autino, or co-authored with Patrick Collins and other dealers of the Astronautic Humanist current.
