A tribute to an extraordinary man and a world-famous intellectual, who has always had a very special bond with our country. One hundred Italian authors, expressing a multiplicity of fields of knowledge, are gathered here to celebrate Edgar Morin's 100 years. Brief portraits of a great humanist, which together give an unprecedented picture of his work and his person. One hundred and more reasons to honor the scholar, teacher and friend, who today, in the midst of this serious world crisis, indicates the horizon of a new planetary humanism and continues to motivate resistance against all forms of barbarism, to build together networks and oases of solidarity, fraternity, creative thinking. To come out, together, from this "Iron Age of the Planetary Era".
