“Matter was itself intelligent, constantly mutating and producing new forms, some of them self-aware. As a child Leopardi had written an essay on ‘the souls of beasts’, and he is clear that consciousness is not confined to humans. The difference between beasts and human beings is not that humans are self-aware while beasts are not. Both are conscious machines. The difference lies in the greater frailty of the human soul, which produces illusions of which beasts have no need.”
