Answer:
Blood
Blood appears throughout the novel as a symbol of a human being’s repressed soul or primal, instinctive self. Montag often “feels” his most revolutionary thoughts welling and circulating in his blood. Mildred, whose primal self has been irretrievably lost, remains unchanged when her poisoned blood is replaced with fresh, mechanically administered blood by the Electric-Eyed Snake machine. The symbol of blood is intimately related to the Snake machine. Bradbury uses the electronic device to reveal Mildred’s corrupted insides and the thick sediment of delusion, misery, and self-hatred within her. The Snake has explored “the layer upon layer of night and stone and stagnant spring water,” but its replacement of her blood could not rejuvenate her soul. Her poisoned, replaceable blood signifies the empty lifelessness of Mildred and the countless others like her.
