Massimo Filippi, a professor of neurology in Milan, is a distinguished anti-speciesism scholar (see, among other work, Questioni di specie, 2017) and a relentless critic of the strict separation of humans and animals, which, according to him, produces and legitimises the ‘crimes’ perpetrated against animals. His article can be read and compared with the one that follows it, by Vasco M. Barreto.
