The idea of ​​margin runs through our lives much more than we believe: the margin is the limit of space and morality, it divides virtue from sin and the center from the periphery. If in the scientific world the margin remembers the error or limit that every research must face, in society it highlights the economic and social marginalization as much as it circumscribes virtuous phenomena of non-conformism. The center and the periphery are places in continuous mutation, crossing art and literature, economy and geography: Francesco Magris traverses these margins on each side, with a curious and complicit step, having fun in crossing all the borders he meets.
