The present issue of HurbineK features four dense essays on different facets of Primo Levi´s work and on themes related to the original Levi repertoire. In the first essay, Márcio Seligman-Silva uses the metaphor of the "boomerang", introduced by Aimé Césaire, to connect the phenomenon of the Shoah with the prior context of colonial violence, which he terms the "postcolonial turn". His analysis incorporates the rich debate developed within this perspective. Maxim Shrayer presents the literary persona and trajectory of the Russian writer Vassily Grossman, whose work serves as a crucial testament to the Soviet Patriotic War against Nazism and to the Shoah, and marked by his non-alignment with the Stalinist regime. Domenico Scarpa, drawing from the extensive biography of Italo Calvino he has published in Italy in 2023, highlights aspects of the relationship between Calvino and Primo Levi-his friend and soulmate-marked by profound existential complicity (political, literary, and fantastical). Among these affinities is the shared sense of disorder inherent in the natural and human worlds, alongside the imposition of "islands of order", which are both necessary and mutable. Simone Ghelli addresses Primo Levi´s atheism by establishing an original and fundamental association between the Italian writer and the skeptical philosopher Pierre Bayle, author of the principal argument for tolerance in the 17th century, who also advocated for a republic of atheists. Ghelli begins with Levi´s story "Verso Occidente," in which a fictional society free from metaphysical convictions expands the scope of human freedom. The essay further explores central themes in Levi´s imagination: chance, anti-theodicy, and the absence of justifications for inequality.
